RESUMO

Introducción: El tratamiento de caninos incluidos maxilares, se basa prin cipalmente en la tracción ortodóntica. Cuando esta fracasa, se suele plantear como alternativa la extracción del canino y la posterior colocación de un implante dental. El autotrasplante se plantea como opción de tratamiento siempre que la extracción íntegra del canino sea viable ya que aporta muchas ventajas como la capacidad de ser movilizados con ortodon cia.Caso clínico: Se describe un caso clínico en el que se realizó un autotrasplante de un canino incluido tras haber fracasado la tracción en una paciente joven. Tras realizar una cirugía regenerativa, fue sometida a tratamiento de ortodoncia y restaurador. Después de 20 meses de seguimiento la paciente se encuentra asintomática, sin signos de movilidad ni reabsorción y con un estable estado periodontal de dicho diente.Conclusión: A pesar de las limitaciones, se puede concluir que siempre que sea viable, el autotrasplante puede constituir una alternativa válida cuando la tracción ortodóntica no funciona, principalmente en pacientes jóvenes en los que no están indicados los implantes (AU)


Introduction: The main treatment of impacted canines is orthodontics. In case of failure, extraction of the canine and the subsequent placement of a dental implant is given as an alternative. Autotransplantation is considered a treatment option as long as the full extraction of the canine is viable, because it provides many advantages as the ability of mobilization with orthodontics Case report: Description of a clinical case in which an autotransplantation of an included canine was carried out after traction failed in a young patient. After regenerative surgery was realized in its surroundings the patient underwent orthodontic and restorative treatment. 18 months of follow–up later the patient remains asymptomatic, with no mobility or resorption signs and with a healthy periodontal state in said canine. Conclusion: Autotransplantation can be a suitable alternative when orthodontic traction has failed, as long as it is viable, especially in young patient when implants are not recommended (AU)

RESUMO

Introducción: Hay alteraciones óseas en las crestas alveolares que presentan un defecto volumétrico que dificultan la inserción de un implante dental en la posición tridimensionalmente correcta. Existen diferentes técnicas quirúrgicas de aumento óseo, entre ellas están los injertos en bloque o Split Bone Bloque Technique (SBBT). Esta técnica combina laminas corticales y hueso particulado de origen autólogo, logrando una integración más rápida del injerto. El objetivo de ese caso es describir el manejo y abordaje clínico de un defecto de alto compromiso estético y complicación quirúrgico-protésica mediante colgajo rotado de paladar, SBBT y posterior provisionalización de un implante dental osteointegrado. Caso clínico: Varón de 54 años que acude a la Clínica Universitaria de la Universidad Rey Juan Carlos con una dehiscencia del tejido blando que sobrepasaba la línea mucoginvival a nivel del incisivo 1.1 cursando con movilidad del fragmento vestibular El paciente no refería sintomatología ni signos patológicos. Se estableció como plan de tratamiento la extracción del diente y aumento del tejido blando mediante la técnica de colgajo rotado de paladar a pedículo posterior. Y posteriormente se realizó la regeneración ósea horizontal mediante SBBT. Conclusión: La regeneración ósea mediante SBBT es una técnica predecible con altas tasas de éxito tanto horizontal como vertical. Asociado a la regeneración, el manejo del tejido blando con colgajos o injertos de tejido conectivo permite obtener el volumen deseado. (AU)


Introduction: There are bone alterations in the alveolar crests that present a volumetric defect that makes inserting a dental implant in the correct threedimensional position difficult. There are different surgical techniques for bone augmentation, including block grafts or the Split Bone Block Technique (SBBT). This technique combines cortical laminas and particulate bone of autologous origin, thus achieving a faster integration of the graft. The aim of this case is to describe the management and clinical approach of a defect with high aesthetic compromise and surgical-prosthetic complication by means of a rotated palatal flap, SBBT and subsequent provisionalization of an osseointegrated dental implant. Case study: A 54 year old man attended the University Clinic of the Rey Juan Carlos University with a dehiscence of the soft tissue that went beyond the mucoginvival line at the level of incisor 1.1 with mobility of the vestibular fragment. The patient did not report any symptoms or pathological signs. Tooth removal and soft tissue augmentation using the rotated palatal to posterior pedicle flap technique were established as a treatment plan. Horizontal bone regeneration was then performed using SBBT. Conclusion: Bone regeneration using SBBT is a predictable technique with high success rates both horizontally and vertically. Associated with regeneration, soft tissue management with flaps or connective tissue grafts makes it possible to achieve the desired volume. (AU)

RESUMO

Actualmente, la implantología está considerada como la terapia de elección para rehabilitar dientes ausentes. Sin embargo, debido a diversos factores, no siempre se consigue un enfoque inmediato para la colocación de los implantes. Se debe prestar una atención especial a los sectores maxilares posteriores, que debido al paso del tiempo y a la ausencia de dientes, sufren una gran atrofia alveolar que se encuentra asociada a una expansión del seno maxilar que dificulta, en ocasiones, la rehabilitación con implantes osteointegrados. Debido a esta pérdida ósea, se han desarrollado técnicas quirúrgicas como la elevación de seno maxilar para obtener una ganancia de hueso y poder favorecer la colocación y el pronóstico de los implantes. Sin embargo, existen situaciones en las que incluso esta técnica no aporta un volumen óseo suficiente, siendo preciso acompañarla de técnicas de regeneración ósea.En la actualidad, existen estudios que plantean el uso de células madre mesenquimales en procedimientos de regeneración ósea como alternativa a los procedimientos convencionales.El objetivo del presente trabajo es evaluar a través de la realización de una revisión sistemática de la literatura, la efectividad de las células madres mesenquimales en elevaciones de seno maxilar con diferentes tipos de matriz ósea. (AU)


Currently, implantology is considered the therapy of choice to rehabilitate missing teeth. However, due to various factors, we do not always get an immediate approach to the placement of our implants. Above all, we must pay special attention to the posterior maxillary sectors, which due to the passage of time and the absence of dental pieces suffer great alveolar atrophy associated with an expansion of the maxillary sinus that makes difficult and sometimes impossible the implant therapy. Due to this great bone loss, the professionals have been forced to practice surgical techniques such as maxillary sinus lift to gain bone and to be able to favour the placement and prognosis of the implants. However, there are clinical situations in which even this technique does not give us sufficient bone volume, being necessary a bone regeneration therapy.Thus, thanks to advances in the field of scientific research, various methods have been used to solve this type of problem, but one of the most innovative and current options is bone regeneration using mesenchymal stem cells.This work aims to evaluate, carrying out a systematic review of the literature, the effectiveness of mesenchymal stem cells in maxillary sinus elevations with several types of matrix.

RESUMO

Objetivo: Describir de forma detallada el abordaje clínico basado en la evidencia científica actual de un implante postextracción con carga y provisionalización inmediata. Caso clínico: Se presenta el caso de una paciente mujer de 32 años de edad, que acude por presentar una posible fractura radicular del incisivo central superior izquierdo (ICSI), acompañada de la aparición de un absceso periodontal en la región del fondo de vestíbulo de dicho diente. Tras llevar a cabo la exploración clínica y radiológica, se establece que el pronóstico del ICSI es desfavorable para llevar a cabo un tratamiento conservador del mismo. Tras la valoración de las características clínicas del caso presente, el plan de tratamiento se inclinó por la realización de la exodoncia del ICSI con la colocación simultánea de un IOI postextracción y la carga inmediata con una prótesis provisional del mismo. Conclusiones: La rehabilitación sobre implantes en situaciones de pérdida dental en el sector anterior estético y en especial, en pacientes jóvenes, requiere un plan de tratamiento multidisciplinar en cuanto a la extracción del diente y colocación del IOI en la posición tridimensional correcta, existiendo diferentes aspectos a tener en cuenta para ello, especialmente el remanente óseo residual, la posición del margen gingival, así como la preservación y acondicionamiento de los tejidos duros y blandos periimplantarios mediante injertos y un manejo correcto de una prótesis provisional hasta conseguir un perfil de emergencia y contorno gingival ideal antes de la corona definitiva. (AU)


Objective: To describe in detail the clinical approach based on current scientific evidence for a post-extraction implant with immediate loading and provisionalisation. Clinical case: We present the case of a 32-year-old female patient who presented with a possible root fracture of the upper left central incisor (ULCI), accompanied by the appearance of a periodontal abscess in the region of the bottom of the vestibule of said tooth. After carrying out the clinical and radiological examination, it is established that the ULCI prognosis is unfavourable for carrying out conservative treatment of the tooth. After assessing the clinical characteristics of the present case, the chosen treatment plan was to extract the ULCI with the simultaneous placement of a post-extraction osseointegrated implant (OII) and immediate loading of a provisional prosthesis on the implant. Conclusions: Rehabilitation on implants in situations of tooth loss in the aesthetic anterior sector, especially in young patients, requires a multidisciplinary treatment plan in relation to tooth extraction and placement of the OII in the correct three-dimensional position. There are various aspects to be taken into account, particularly the residual remaining bone, the position of the gingival margin, as well as the preservation and conditioning of the peri-implant hard and soft tissues by means of grafts and proper handling of a provisional prosthesis until an ideal emergence profile and gingival contour is achieved before the final crown.

RESUMO

The advantages of dental autotransplantation and its high level of clinical success mean that it should be considered as a therapeutic option when replacing a lost tooth. In order to achieve optimum results, it is necessary to know the technique of dental autotransplantation, promoting its use whenever the clinical conditions to perform it are present. The objective of this article is to describe the technique in detail by means of a clinical case of a dental autotransplant whose donor tooth was a third unerupted molar. A 39-year-old male patient with no medical history of interest. On clinical examination, tooth 2.6 shows vertical fracture with indication of exodontia. A compatibility study is carried out using a CBCT and after this, a subsequent preparation of a 3D-printed replica of the donor tooth 2.8 is made. A step-by-step description is given of the autotransplantation technique from 2.8 to 2.6. After this, antibiotic coverage, semi-rigid splinting and root canal treatment are carried out in a short time. Results are shown at 12 months. The main factor for the success of this technique is the preservation of periodontal ligament cells. The unerupted teeth are the only ones that fully preserve the periodontal ligament, but they require greater surgical skills. Autotransplantation is a predictable treatment alternative to dental implants, being above all an option indicated to replace teeth with dental fissures or vertical root fractures or poor restorative and/or endodontic prognosis. The third molars are the most used teeth for transplantation, due to their indications for extraction in a high percentage preserving the entire periodontal ligament. The diagnosis by CBCT and the use of 3D- printed replicas of the tooth to be transplanted have meant a highly significant improvement in the prognosis and predictability of the technique. Key words:Dental autotransplant, tooth replica, third molar.

RESUMO

El mucocele oral es una lesión de los tejidos blandos con alta prevalencia en la cavidad oral, siendo motivo de consulta dadas las alteraciones funcionales y es-téticas asociadas al mismo. Su etiología está relacionada con la alteración en las glándulas salivales, correspondiendo la localización más frecuente al labio inferior. Su tratamiento, aunque en la mayoría de los casos es expectante, consiste en la extirpación quirúrgica debido a que pue-den llegar a ser de tamaño considerable. A continuación se describe el caso de un paciente varón, de avanzada edad, que presenta un mucocele de gran tamaño localizado en el labio inferior, región en la que se practicó su remoción quirúrgica y posterior análisis histopatológico


The oral mucocele is a soft tissue lesion with high prevalence in the oral cavity, the oral mucocele can be find associated with functional and aesthetic alterations. The etiology is related to the alteration in the salivary glands, the most frequent location corresponding to the lower lip. The treatment consists in surgical removal because they can be of considerable size. The following describes the case of a male patient, of advanced age, who has a large mucocele located in the lower lip, a region in which surgical removal was performed and subsequent histopathological análisis

RESUMO

OBJETIVO: El objetivo de este artículo es describir la rehabilitación sobre implantes en un caso de alta demanda estética, basando dicho tratamiento en una planificación íntegramente digital. CASO CLÍNICO: Se presenta el caso clínico de una paciente de 52 años de edad que acude por fractura del diente 2.1. Tras el diagnóstico y análisis, tanto de forma clínica como radiográfica, se determina un pronóstico restaurador imposible para el 2.1, planificando como tratamiento una rehabilitación implantosoportada. Se realizó un escaneado de la zona a tratar para llevar a cabo un estudio detallado del caso y la confección de una corona provisional, la cual se atornilló en el mismo momento de la cirugía a un implante colocado de forma inmediata postextracción. Sumado a ello, se realizaron injertos de tejido duro y blando para asegurar el mantenimiento de los contornos periimplantarios. Tras el periodo de integración del implan-te, se trabajó el contorno de la corona provisional hasta conseguir un perfil de emergencia y un volumen de tejido gingival idóneos. Tanto el perfil de emergencia conseguido como el contorno del provisional fueron escaneados, junto con la posición del implante, para la confección de la restauración metal-cerámica definitiva. A los 6 meses tras la finalización del caso, se observa una estética de tejidos blandos idónea y un mantenimiento perfecto de toda la arquitectura gingival. CONCLUSIÓN: El manejo del sector estético anterosuperior evidencia una clara exigencia estética. En casos de pérdida dentaria en esta localización, la rehabilitación fija sobre implantes es el tratamiento de elección. No obstante, para conseguir un resultado adecuado y predecible, es esencial un correcto manejo quirúrgico y protésico. La planificación mediante medios digitales supone un salto de calidad en el enfoque terapéutico de estos casos, permitiendo un tratamiento más exacto e individualizado y siendo, además, más sencilla y eficiente la información que se traslada al laboratorio protésico


AIM: The purpose of this article is to present a clinical case of high aesthetic demand. Such planning and treat with digital flow, included diagnosis, prosthetic planning and finally, the placement of the final prosthesis. CASE REPORT: A 52-year-old woman presents a fracture of the tooth 2.1. After diagnosis and analysis both clinically and radiographically, an impossible restorative prognosis is determined for 2.1, planning implant-supported rehabilitation as treatment. A scan of the area to be treated was carried out to carry out a detailed study of the case and the preparation of a provisional crown, which was screwed at the same time of surgery to an implant placed immediately post-extraction. Besides, hard and soft tissue graft were placed to guarantee the maintenance of the peri-implant contours. After the implant osteointegration, the contour of the provisional crown was scanned to obtain a suitable emergence profile and gingival tissue volume. Both the emergency profile obtained and the contour of the provisional were scanned together with the position of the implant for the preparation of the final metal-ceramic restoration. After six months, it can observe an ideal soft tissue aesthetic and perfect maintenance of the entire gingival architecture. CONCLUSION: The management of the anterior superior aesthetic sector shows a clear aesthetic demand. In cases of tooth loss at this location, fixed implant rehabilitation is the treatment of choice. However, to achieve an adequate and predictable result, proper surgical and prosthetic management is essential. Digital flow it present like alternative and a quality leap in the therapeutic approach to these cases, a more accurate and individualized treatment, and the information that is transferred to the prosthetic laboratory is more simple and efficient

RESUMO

Ellis-van Creveld syndrome (EVC) or chondroectodermal dysplasia is an autosomal recessive disorder, characterized by dwarfism, polydactyly, hypoplastic fingernails and congenital heart defects, finding in most of the cases orofacial anomalies. We describe a clinical case of a 9 year old male patient diagnosed with EVC who visited our Maxillofacial private consultation at Alcorcon Southern Hospital, presenting typical oral manifestations such as dental agenesis, delayed eruption, hypoplasia of the enamel, dental dysmorphism, taurodontism and supernumerary teeth. EVC syndrome is a rare disease and requires a multidisciplinary approach. Oral features are constant and requires the jointly performance of Odontologist and Maxillofacial surgeon aiming to get an appropriate treatment sequence surgery-orthodontics in order to achieve a suitable functional result to improve the quality of life of these patients. Key words:Ellis-Van creveld syndrome, chondroectodermal dysplasia, oral manifestations, craniofacial manifestations.

RESUMO

La enfermedad o disfunción hepática puede deberse a numerosas causas como infecciones adquiridas, patologías congénitas o el abuso de drogas. Cuando esta disfunción y el daño hepático se prolongan a lo largo del tiempo, puede desembocar en una cirrosis hepática, cuadro irreversible y de graves repercusiones para el enfermo. Las dos patologías hepáticas más frecuentes y principales causas de la cirrosis son la hepatitis o inflamación hepática, la cual se puede deber a numerosos factores siendo el más frecuente las infecciones por virus, y la enfermedad hepática alcohólica, provocada por el abuso de alcohol continuado durante un largo período de tiempo. El manejo odontológico de un paciente con alteraciones hepáticas supone un verdadero reto, ya que el hígado juega un papel vital en numerosas funciones metabólicas, como la secreción de bilis o la excreción de bilirrubina procedente del metabolismo de la hemoglobina. Un fallo en la función hepática puede suponer alteraciones en el metabolismo de aminoácidos, amoníaco, proteínas, hidratos de carbono y triglicéridos. Un paciente con patología hepática tendrá un metabolismo alterado de numerosos fármacos empleados habitualmente por el dentista, tendrá un mayor riesgo de hemorragia debido a anomalías en la síntesis de diferentes factores de coagulación, siendo además un paciente con mayor riesgo de infecciones. La gran repercusión de la enfermedad hepática, así como el notable desconocimiento de muchos profesionales odontólogos en su manejo, justifican este artículo donde se talla tanto las generalidades más importantes de esta entidad como sus principales manifestaciones orales y consideraciones en el manejo odontológico


Liver disease or dysfunction may be due to numerous causes such as acquired infections, congenital pathologies or drug abuse. When this dysfunction and liver damage are prolonged overtime, it can lead to hepatic cirrhosis, an irreversible condition and serious repercussions for the patient. The two most frequent liver diseases and major causes of cirrhosis are hepatitis or hepatic inflammation, which may be due to numerous factors being the most frequent virus infections, and alcoholic liver disease, caused by alcohol abuse continued during A long period of time. The dental management of a patient with liver disorders is a real challenge, since the liver plays a vital role in many metabolic functions, such as bile secretion or excretion of bilirubin from hemoglobin metabolism. A failure in liver function can lead to alterations in the metabolismof amino acids, ammonia, proteins, carbohydrates and triglycerides. A patient with liver disease will have an altered metabolism of numerous drugs commonly used by the dentist, will have a greater risk of hemorrhage due to abnormalities in the synthesis of different coagulation factors, being also a patient with a higher risk of infections. The great repercussion of liver disease, as well as the remarkable lack of knowledge of many dental professionals in its management, justify this article where it is detailed both the most important generalities of this entity as its main oral manifestations and considerations in dental management

RESUMO

El objetivo del trabajo es describir el caso clínico de un hombre de 67 años con el Síndrome de Rendu-Osler-Weber (SROW). A la exploración, se pueden apreciar múltiples telangiectasias en la región facial, algunas puntiformes en los lóbulos de ambos pabellones auriculares y otras lineales en el área nasogeniana. A nivel intraoral, se observan telangiectasias de pequeño tamaño en labio, lengua, paladar, encía, y mucosa yugal. Así mismo, presenta lesiones vasculares clínicamente identificadas como hemangiomas intraorales. Según la literatura, la epistaxis es el signo clínico más frecuente en los pacientes con el SROW y el principal motivo de consulta. También es frecuente la presencia de telangiectasias que se pueden observar principalmente en labios (34%), lengua (33%), mucosa yugal (17%), paladar (10%) y encía (6%). Los odontólogos pueden ser los primeros en sospechar el cuadro por la presencia de lesiones orales y ayudar a un diagnóstico precoz por lo que pueden desempeñar un papel clave en el manejo de estos pacientes que incluirá un control y tratamiento multidisciplinar debido a las diferentes manifestaciones de esta entidad


The aim of this study is to describe the clinical case of a 67-yeart-old man with SROW. At the exploration, multiple telangiectasias can be seen in the facial region, some punctiform in the lobes of both atrial and other linear in the nasogenian area. At the oral level, small telangiectasias are seen on the lip, tongue, palate, gums, and buccal mucosa. it also presents vascular lesions clinically identified as intraoral hemangiomas. According to the literature, epistaxis is the most frequent clinical sign in patients with SROW and the main reason for consultation. It is also frequent the presence of telangiectasias that can be seen mainly on lips (34%), tongue (33%), yugal mucosa (17%), palate (10%) and gums (6%). Dentists may be the first to suspect the condition due to the presence of oral lesions and to help early diagnosis, so they can play a key role in the management of these patients, including multidisciplinary treatment and control due to the different manifestations of this condition.

RESUMO

BACKGROUND: For the treatment of the bisphosphonates and other drugs related osteonecrosis of the jaws, currently medication-related osteonecrosis of the jaws (MRONJ), have been established different conservative therapeutic approaches, avoiding surgery except in cases of extreme need. Given the controversy and lack of current consensus regarding MRONJ therapy in patients, new techniques have been developed among which the use of fibrin membranes rich in platelets and leukocytes (L-PRF). The objective of this review is to evaluate whether L-PRF treatment is really effective, as well as the results that can be achieved by this therapeutic alternative. MATERIAL AND METHODS: A review of the literature in the PubMed/Medline database of all those studies using L-PRF in the treatment of osteonecrosis using the keywords "Osteonecrosis", "Jaws", "L-PRF" and " Leucocyte-rich platelet-rich fibrin ". RESULTS: The use of L-PRF for the treatment of MRONJ is really effective, especially when it is performed with a simultaneous application of L-PRF and morphogenetic protein-2 (BMP-2), even in patients submitted for long periods of time to therapy with intravenous bisphosphonates. However, success will depend on several factors such as the previous existence of infection or the clinical stage in which the patient is. CONCLUSIONS: The current literature demonstrates the effectiveness of the use of L-PRF in osteonecrosis, and it can be considered as a real alternative in the treatment of this entity. However, more clinical studies are needed to really assess this new therapy. Key words:Osteonecrosis, Jaws, L-PRF, Leucocyte-rich platelet-rich fibrin.

RESUMO

BACKGROUND: Since its appearance in the dental area, the laser has become a treatment of choice in the removal of lesions in the oral soft tissues, due to the numerous advantages they offer, being one of the most used currently the diode laser. The aim of this review was to determine the efficacy and predictability of diode laser as a treatment of soft tissue injuries compared to other surgical methods. MATERIAL AND METHODS: A literature review of articles published in PubMed/MEDLINE, Scopus and the Cochrane Library databases between 2007 and 2017 was performed. "Diode laser", "soft tissue", "oral cavity" and "oral surgery" were employed for the search strategy. Only articles published English or Spanish were selected. RESULTS: The diode laser is a minimally invasive technology that offers great advantages, superior to those of the conventional scalpel, such as reduction of bleeding, inflammation and the lower probability of scars. Its effectiveness is comparable to that of other types of lasers, in addition to being an option of lower cost and greater ease of use. Its application in the soft tissues has been evaluated, being a safe and effective method for the excision of lesions like fibromas, epulis fissuratum and the accomplishment of frenectomies. CONCLUSIONS: The diode laser can be used with very good results for the removal of lesions in soft tissues, being used in small exophytic lesions due to their easy application, adequate coagulation, no need to suture and the slightest inflammation and pain. Key words:Diode laser, soft tissues, oral cavity, oral surgery.

RESUMO

Objetivo: El objetivo del presente artículo fue describir un caso clínico sobre regeneración periodontal y determinar, a propósito del mismo, la eficacia y la predictibilidad de las diferentes técnicas regenerativas en el tratamiento de defectos intraóseos causados por la periodontitis. Caso clínico: Se presenta el caso de un paciente varón de 65 años con periodontitis crónica avanzada localizada en el incisivo central superior derecho donde se planificó, en la fase de reevaluación, cirugía de regeneración debido a un defecto intraóseo visible radiográficamente, que se correspondía con una profundidad de sondaje de 11 mm. La lesión, que afectaba a la pared vestibular, distal y palatina, fue tratada con una combinación de xenoinjerto óseo (IOs), membrana de colágeno reabsorbible (RTG) y proteínas derivadas de la matriz del esmalte (PMEs), obteniendo como resultado una reducción en la profundidad de sondaje de hasta 7 mm después de nueve meses. Conclusión: La regeneración periodontal ha demostrado ser eficaz para el tratamiento de defectos intraóseos que comprometen la supervivencia del diente, ayudando al propio paciente a mantener una correcta salud y función oral (AU)


Aim: The aim of the present article was to describe a clinical case on periodontal regeneration and to assess the efficacy and predictability of different regenerative techniques for the treatment of intrabony defects caused by periodontitis. Case report: It presents the case of a 65- year-old male patient with localized severe chronic periodontitis where, after receiving basic periodontal treatment, regeneration surgery in tooth #11 was planned due to a radiographically visible intraosseous defect, corresponding to a pocket depth of 11 mm. The lesion, affecting the buccal, distal and palatal walls, was treated with a combination of bone xenograft (BGs), resorbable collagen membrane (GTR) and enamel matrix proteins (EMPs), resulting in a reduction in pocket depth up to 7 mm after nine months. Conclusion: Periodontal regeneration has been shown to be effective for the treatment of an intrabony defect that compromises tooth survival by helping the patient to maintain proper oral health and function (AU)

RESUMO

Introducción: El cáncer oral representa el 1-2% de todos los cánceres del organismo, correspondiendo el 90% a carcinomas orales de células escamosas (COCE). Los factores de riesgo clásicamente implicados en el desarrollo del cáncer oral son la edad avanzada, el sexo masculino y la exposición prolongada a hábitos como el alcohol, el tabaco y la nuez de betel. Sin embargo, el incremento en los últimos años de la incidencia de COCE en pacientes jóvenes sin exposición a factores de riesgo clásicos ha puesto en manifiesto la presencia de otros posibles agentes etiopatogénicos, entre los que destaca el virus del papiloma humano (VPh). Objetivos: Poner de manifiesto el desarrollo molecular del COCE por la intervención del VPh como oncovirus y sus características. Resultados: Los estudios determinan el alto riesgo oncogénico que presenta el subtipo 16 y 18 del VPh actuando a través de sus proteínas E6 y E7, afectando directamente al p53, a la proteína del Retinoblastoma (pRb) y otras enzimas implicadas en la regulación del ciclo celular como la PI3K, alterándose así los procesos de apoptosis, proliferación y diferenciación celular. Conclusiones: El VPh juega un papel importante como carcinógeno en la aparición del COCE, con un pronóstico más favorable respecto a otros factores etiológicos. El proceso de oncogénesis en el desarrollo del COCE a partir del VPh está determinado por los subtipos de alto riesgo, así como la expresión de las proteínas virales E6 y E7, responsables de inhibir la actividad de los genes supresores de tumores del ciclo celular (AU)


Introduction: Oral cancer represents 1-2% of all cancer in the organism, 90% corresponding to oral squamous cell carcinomas (OSCC). Risk factors traditionally involved in the development of oral cancer are advanced age, male sex, and prolonged exposure to habits such as alcohol, tobacco, and betel nut. The increase in the incidence of OSCC in young patients without exposure to classical risk factors in recent years has revealed the presence of other possible etiopathogenic agents, especially the human Papilloma Virus (hPV). Objectives: Describe the molecular development of the OSCC by the hPV intervention as oncovirus and its characteristics. Results: Different studies show the high oncogenic risk of hPV 16 and 18 subtypes acting through their E6 and E7 proteins, directly affecting p53, Retinoblastoma protein (pRb) and other enzymes involved in the regulation of the cycle Cell as the PI3K, altering the processes of apoptosis, cell proliferation and differentiation. Conclusions: hPV plays an important role as a carcinogen in the onset of OSCC, with a more favorable prognosis regarding other etiological factors. The process of oncogenesis in the development of COCE from hPV is determined by the high risk subtypes as well as the expression of the viral proteins E6 and E7 responsible for inhibiting the activity of the cell cycle tumor suppressor genes (AU)

RESUMO

Objetivo: Conocer las principales ventajas, inconvenientes y nuevas alternativas del tratamiento de expansión rápida palatina quirúrgicamente asistida o ‘SARPE’ (Surgically Assisted Rapid Palatal Expansion), realizando para ello una revisión de la literatura científica a propósito de un caso clínico de una compresión transversal del maxilar en un paciente adulto. Caso clínico: Paciente mujer de 19 años con mordida cruzada posterior bilateral asociada a hipoplasia del maxilar a la que se decide realizar un tratamiento de expansión rápida quirúrgicamente asistida. La peculiaridad de este caso se encuentra en que antes de la cirugía se colocó un disyuntor hecho a medida anclado directamente al hueso palatino. Se realizó la cirugía, la expansión y el posterior tratamiento de ortodoncia y, tras un período de seguimiento, se pudo observar una significativa expansión maxilar, evitando los inconvenientes dentales y periodontales de la técnica tradicional. Conclusiones: Los nuevos procedimientos tienden a realizar un anclaje del disyuntor al hueso palatino mediante microtornillos, consiguiendo una expansión palatina satisfactoria, pero evitando los inconvenientes que provoca utilizar un disyuntor dentoanclado (AU)


Objective: To know the main advantages, disadvantages and new alternatives of the treatment of Surgically Assisted Rapid Palatal Expansion (SARPE), making for it a review of the scientific literature on purpose of a clinical case. Clinical case: A 19-year-old female patient with bilateral posterior crossbite associated with maxillary hypoplasia who was decided to perform a surgically assisted rapid expansion treatment. The peculiarity of this case is that before the surgery was placed a custom-made distractor anchored directly to the palatal bone. Surgery, expansion and subsequent orthodontic treatment were performed and, after a follow-up period, a significant maxillary expansion was observed, avoiding the dental and periodontal drawbacks of the traditional technique. Conclusions: New procedures tend to make a direct bone placement of the distractor by means of microimplants, achieving satisfactory palatal expansion but avoiding the inconveniences of using a dental anchorage disjunctor (AU)
