RESUMO

La implantología oral clínica ha evolucionado significativamente durante las últimas décadas. El desarrollo de los aspectos diagnósticos, quirúrgicos y prostodóncicos ha mejorado la predictibilidad de la oseointegración y los resultados clínicos a largo plazo del tratamiento con implantes. Además, algunos criterios de condiciones clínicas y radiográficas se han incorporado al concepto de éxito, como el nivel de los implantes, los tejidos periimplantarios, el nivel de la prótesis y el grado de satisfacción de los pacientes. La evidencia científica ha demostrado que el tratamiento con implantes es una excelente opción para la rehabilitación de los pacientes con parcial y total edentulismo. De hecho, los estudios a largo plazo reflejan el éxito de las rehabilitaciones fijas, sobredentaduras, puentes fijos y coronas unitaria. Sin embargo, algunas complicaciones biológicas y prostéticas han definido los conceptos diferentes de éxito y supervivencia de los implantes dentales. Conclusiones: Este trabajo indica que las restauraciones sobre implantes dentales en la rehabilitación de los pacientes parcial y totalmente edéntulos constituye un tratamiento odontológico con resultados clínicos a largo plazo con un elevado éxito.

Clinical implant dentistry has evolved significantly during last decades. The development of diagnostic, surgical and prosthetic aspects has improved the predictability of osseointegration and long-term clinical outcomes of the implant treatment. Moreover, several criteria of clinical and radiographic conditions have been incorporated in the concept of implant success, as implant level, peri-implant tissues, prosthetic level, and patient satisfaction. The scientific evidence of the literature demonstrates that implant treatment is an excellent option for the rehabilitation of patients with partial and total edentulism. In fact, long-term studies are reported the success of fixed total rehabilitation, overdentures, fixed bridges and single crowns. However, some biological and technical complications are defined the different concepts of success and survival of prosthetic and dental implants. Conclusions: This paper indicates that restorations with dental implants in the rehabilitation of partially and totally edentulous patients constitute a dental treatment with long-term clinical outcomes with a high success.

RESUMO

Introducción: El objetivo del presente estudio era mostrar los resultados clínicos del tratamiento del maxilar superior posterior con implantes colocados mediante la técnica de elevación transalveolar del seno maxilar en pacientes geriátricos. Pacientes y Métodos: 24 pacientes geriátricos (15 hombres y 9 mujeres) con pérdidas dentales maxilares fueron tratados con 28 implantes diferentes colocados mediante la técnica de elevación sinusal transalveolar para su posterior rehabilitación prostodóncica. Los implantes fueron cargados después de un periodo de cicatrización de 6 meses. Resultados: Los hallazgos clínicos indican una supervivencia y éxito de los implantes del 96,4%. En un paciente de los 24 tratados (4,2%) se perdió un implante (3,6%). La altura ósea residual media fué de 6,38 ±1,10 mm (rango:5-10 mm). La ganancia media de hueso vertical fué de 4,40 ±1,15 mm (rango: 2-7 mm). 67,8% de los implantes se insertaron en localización molar y el 32,2% en la localización premolar. Se utilizaron biomateriales en el 97,8% de los implantes. Se realizaron coronas unitarias en 20 pacientes (83,3%), puentes fijos en 3 pacientes (12,5%) y una sobredentadura con bolas en un paciente (4,2%). El seguimiento medio de los pacientes estudiados ha sido de 64,2 ±8,6 meses con un rango entre 50 y 82 meses. Conclusiones: Este estudio indica que el tratamiento con implantes dentales mediante la elevación transalveolar del seno maxilar superior en pacientes geriátricos, constituye una terapéutica implantológica con una elevada tasa de éxito.

RESUMO

La evolución en los diseños de los sistemas de implantes y en la configuración de los pilares protésicos ha desarrollado el concepto de plataforma reducida que comprende la colocación de un pilar más estrecho que la plataforma del implante para aumentar su distancia de la interfase hueso-implante. La plataforma reducida es considerada un factor importante para preservar la estabilidad del hueso crestal y de los tejidos blandos y asegurar el éxito de los implantes dentales a largo plazo. La plataforma reducida reduce las fuerzas oclusales y la contaminación bacteriana en la interfase entre el hueso crestal y el implante. Los estudios experimentales en animales y clínicos en pacientes muestran su eficacia para prevenir la pérdida ósea y de los tejidos blandos periimplantarios


The evolution of designs of implant systems and abutments configurations has developed the concept of platform-switching that involves the connection of a narrower abutment to the platform implant to allow horizontal distance of the interface bone-implant. Platform-switching is considered an important factor to preserve the stability of crestal bone and soft tissue ensuring the success of dental implants in the long-term follow-up. Platform-switching reduces the forces of occlusal loading and bacterial contamination in the interface between the crestal bone and the implant. Experimental studies in animals and clinical studies in patients showed that implants with platform-switching have demonstrated the effectiveness to prevent peri-implant bone loss and subsequent soft tissue los

RESUMO

La planificación preoperatoria de la posición de los implantes constituye una parte importante de la coordinación quirúrgica y prostodóncica que se ha ido incrementando para conseguir resultados funcionales y estéticos. La cirugía guiada de implantes ha aumentado su popularidad, particularmente debido a los avances y a la utilización de la tomografia computarizada de haz cónico (CBCT) y a la planificación del tratamiento con implantes mediante programas informáticos 3D que valoran la localización del implante. De hecho, los pacientes edéntulos pueden ser diagnosticados con una CBCT y tratados con varios implantes por cirugía guiada y carga inmediata. La CBCT constituye un método no invasivo para describir las estructuras maxilofaciales evaluando la cantidad y calidad ósea de los rebordes alveolares. La incorporación de softwares específicos de implantología guiada puede mejorar la planificación virtual de la cirugía sin colgajo y los resultados de los implantes colocados con una férula quirúrgica guiada. En muchos casos, la carga inmediata optimiza el éxito de la técnica de cirugía guiada con muchos beneficios como la reducción del tiempo del tratamiento y el confort del paciente


Preoperative planning of the implant position as part of a coordinated prosthetic and surgical concept is becoming increasingly important regarding function and esthetics. Guided implant surgery is increasing in popularity, particularly due to advances and increased usage of cone beam computed tomography (CBCT) and dental implant treatment planning software allowing three-dimensional assessment of the implant site. In fact, edentulous patients can be diagnosed by a CBCT and treated with several implants for rehabilitation with guided surgery and immediate loading. The CBCT provides a noninvasive method to describe maxillofacial structures and assess bone volume and density of alveolar ridges. The introduction of specific softwares of guided implant dentistry can improve the virtual planning of flapless surgery and outcomes of dental implant placed in edentulous alveolar ridges by template guided surgery. In many cases, the immediate-loading protocol maximises the sucess of the guided surgery techniques with many benefits, such as short time and maximum patient comfort

RESUMO

Un adecuado volumen óseo es uno de los factores críticos para conseguir la oseointegración a largo plazo. En situaciones con un inadecuado volumen de hueso, especialmente la mandíbula atrófica, las técnicas de aumento del reborde alveolar son frecuentemente necesarias para un tratamiento predecible con implantes. Los injertos son fundamentales para reparar y regenerar el tejido óseo. Además, algunos biomateriales han sido evaluados para la regeneración ósea como material de relleno dependiendo de sus características y el área de aplicación. Los injertos autólogos han sido considerados como el material ideal de aumento óseo. Muchas técnicas de han desarrollado para reconstruir estos defectos alveolares. De acuerdo con la técnica, se regulariza el reborde alveolar y se utiliza el bloque de injerto solo o con hueso particulado o biomateriales, estabilizados con tornillos de osteosíntesis. Conclusiones: Este estudio indica que la rehabilitación de la mandíbula atrófica mediante técnicas quirúrgicas complejas con injertos óseos e implantes constituye un tratamiento con una elevada tasa de éxito


An adequate volume of bone is one of the factors critical to successful osseointegration and long-term retention of endosseous dental implants. In situations where inadequate bone volumes exist, specially atrophic mandible, osseous ridge augmentation procedures often are necessary for predictable implant therapy. Grafts are fundamental for regenerating and repairing of bone tissue. Moreover, several types of filling biomaterials have been evaluated for bone regeneration and the choice of the biomaterial mostly depends on its features and application site. Autogenous bone grafts are generally considered one of the more ideal augmentation materials. Many different techniques have been developed to reconstruct deficient alveolar jaws. According to bone graft technique, after the surgical exposure and the removal of any irregularity of the residual ridge, autologous bone blocks, used alone or associated with particulated bone and bone substitutes, are stabilized by means of small bone screws. Conclusiones: This study indicate that rehabilitation of atrophic mandible by advanced surgery techniques with bone grafts and dental implants constitute a treatment with a high success rate

RESUMO

La superficie de los implantes es muy importante para la oseointegración. La superficie rugosa de titanio puede influir en los resultados experimentales y clínicos. Diferentes instrumentos y técnicas de mediciones pueden influir notablemente en los resultados de la caracterización topográfica de los implantes. Las superficies han sido documentadas mediante microscopio electrónico de barrido. La interferometría de luz blanca puede identificar las irregularidades en la superficie por cambios en la luz reflejada. La composición química de las superficies puede ser determinada por la técnica de espectroscopía fotoelectrónica de rayos X. La composición química refleja los procedimientos de la fabricación de los implantes. Una variedad de elementos y compuestos químicos no relacionados con la composición del titanio pueden encontrarse en algunos tipos de implantes; como material inorgánico (ej. cloruro de sodio) y compuestos orgánicos de carbono que pueden deberse a la contaminación durante la fabricación y el almacenaje. Conclusiones: Las modificaciones en la topografía y en la composición química de la superficie de los implantes constituye un importante campo en la implantologia oral experimental y clínica


Implant surface is very important for the osseointegration. Roughened surface titanium may influence in experimental and clinical results. Different measures instruments and techniques strongly influence the outcome of a topographic characterization of surface implant. Surfaces has been documented by scanning electron microscopy. White light interferometer may identify the surface irregularities that cause phase changes in the reflected light. The surfaces chemical composition was determined using a technique of X-ray photoelectron spectroscopy. Chemical composition reflect the type of fabrication procedures applied to implants. A variety of elements and chemical compounds not related to the titanium composition were found on some implant types. They ranged from inorganic material (i.e. sodium chloride) to specific organic as carbon compounds believed to be due to contamination during fabrication or storage. The experimental findings are believed to make a contribution to a better understanding of the interplay between industrial fabrication procedure and physico-chemical implant surface properties. Conclusions: The topographic and chemical composition modifications of surface implants constitute an important field in experimental and clinical implant dentistry

RESUMO

Los fenómenos biológicos de la oseointegración comprenden un proceso de reabsorción y formación ósea que ha sido descrito en estudios histológicos en animales y humanos. La extracción de dientes seguida de la inserción de implantes inmediatos provoca alteraciones en las dimensiones del hueso alveolar con gaps horizontales y verticales entre las paredes del alveolo y el implante. La reabsorción de la pared vestibular parece ser más pronunciada. Esta deshicencia ósea despues de la inserción de implantes postextracción ha sido corroborada en experimentos con animales y confirmada en studios clínicos con pacientes. Diversos factores pueden afectar a la respuesta biológica de los tejidos periimplantarios y el contacto hueso-implante en los alveolos postextracción como la densidad de hueso, la superficie y el diseño del implante y la técnica quirúrgica. Conclusión: La investigación experimental y clínica indica que la inserción de implantes en alveolos frescos no perjudica la remodelación de los tejidos periimplantarios. Sin embargo, tiene lugar la reabsorción ósea tanto de la pared vestibular como lingual


The biology of osseointegration involve a process of healing with bone resorption and bone apposition, as described histologically in animal and human studies. The removal of teeth followed by immediate implant placement results in marked alterations to alveolar ridge dimensions as well as horizontal and vertical gaps between the bone walls and the implant. Resorption of the buccal plate was seen to be more pronounced; this bone dehiscence following implant placement corroborates findings reported in animal experiments and confirmed in clinical studies with patients. Several factors affecting the biologic response of peri-implant tissues and bone-implant contact in postextraction implants as original bone density, implant surfaces, implant design and surgical technique. Conclusions: Experimental and clinical research studies suggest that the insertion of implant in fresh sockets does not jeopardize remodeling of periimplant tissues. However, bone resorption can be expected on both the lingual and buccal aspects

RESUMO

Introducción: El objetivo del presente estudio era mostrar los resultados del tratamiento con implantes dentales insertados mediante la técnica de elevación transcrestal en el maxilar superior. Pacientes y Metodos: 47 pacientes (18 hombres y 29 mujeres) con pérdidas dentales maxilares fueron tratados con 60 implantes IPX ® Galimplant con conexión interna y superficie arenada y grabada fueron insertados mediante la técnica de elevación sinusal transcrestal para la rehabilitación del maxilar posterior. Los implantes fueron cargados después de un periodo de cicatrización de 6 meses. Resultados: Los hallazgos clínicos indican una supervivencia y éxito de los implantes del 100%. La ganancia media de hueso vertical fué de 4,8 mm (rango: 2-6,5 mm). 46,7% de los implantes se insertaron en localización molar y el 53,3% en la localización premolar. Biomateriales fueron utilizados en el 91,7% de los implantes. Después de un periodo medio de carga funcional de 37,6 meses (rango: 24-52 meses), no ha habido complicaciones tardías. El 70% de los implantes fueron rehabilitados con coronas unitarias y el 30% con puentes fijos. Conclusiones: Este estudio indica que el tratamiento con implantes dentales mediante su inserción con elevación transcrestal del seno maxilar superior constituye una terapéutica implantológica con éxito


Introduction: The aim of this study was to report the outcome of treatment with maxillary dental implants inserted by transcrestal sinus elevation. Patients and Methods: 47 patients (18 males and 29 females) with maxillary tooth loss were treated with 60 IPX ® Galimplant internal connection and sandblasted and acid-etched surface implants inserted by transcrestal sinus elevation for rehabilitation of posterior maxilla. Implants were loaded after a healing free-loading period of 6 months. Results: Clinical results indicate a survival and success rate of implants of 100%. The mean elevation height was 4.8 mm (range: 2-6.5 mm). 46.7% of implants were inserted in molar and 53.3% in premolar localization. Bone substitutes were used in 91.7% of implants. After a mean functioning period of 37.6 months (range: 24-52 months), no late complications were reported. 70% of implants were restored with single crowns and 30% with fixed bridges. Conclusions: This study indicate that treatment with dental implants inserted in maxilla by transcrestal sinus elevation constitute a successful implant treatment

RESUMO

BACKGROUND: The aim of this prospective study was to report the outcome of treatment with implants inserted after tooth extraction and immediately loaded. MATERIAL AND METHODS: Fifty-six patients with single tooth loss were treated with 116 IPX Galimplant® implants with internal connections and a sandblasted, acid-etched surface. All implants were placed after tooth extraction using a flapless approach without bone regeneration, and they were then immediately loaded with cemented acrylic prostheses. After a period of three months, definitive cemented ceramic prostheses were placed. Patients were examined throughout a total of 4 years of follow-up. Marginal bone loss and survival rates were evaluated using digital periapical radiographs, taking into account clinical variables such as age, gender, smoking, history of periodontitis, etiology of extraction, placement site, diameter, and implant length. The Mann-Whitney U and Kruskal-Wallis non-parametric tests were used to compare differences between subgroups created based on the different clinical variables identified. RESULTS: Clinical results indicate an implant survival and success rate of 97.4%. Three implants were lost. Of the 116 immediate acrylic single crowns initially placed, 113 were replaced with definitive ceramic crowns after 3 months. A total of 77.8% of implants were inserted in the maxilla, while 22.2% were inserted in the mandible. No further complications were reported after the follow-up period (4 years). The mean marginal bone loss was 0.67 mm ± 0.40 mm. No differences were found among the subgroups of study patients. CONCLUSIONS: This study indicates that dental implants that are inserted after tooth extraction and immediately loaded may constitute a successful and predictable alternative implant treatment.

RESUMO

BACKGROUND: The aim of this study was to assess the dental status (DMFT) in patients with schizophrenia compared with a control group. MATERIAL: In this case-control study, 50 patients with schizophrenia attended in the Psychiatric Unit at the Virgen Macarena University Hospital of Seville were compared with 50 people (without systemic diseases and not taking psychotropic drugs) in a control group attended in the School of Dentistry of Seville. Decayed, missing and filled teeth (DMFT) were assessed according to the World Health Organization WHO criteria. RESULTS: Patients with schizophrenia showed a decayed teeth (DT) score of 7.26 ± 5.69 compared with 6.50 ± 4.37 for patients the control group. These differences were significant and suggest that dental caries are most prevalent in patients with schizophrenia. People who smoked showed significantly higher DT scores in both groups. Among patients with schizophrenia, smokers scored 9.34 ± 5.42 compared with 4.38 ± 4.82 for non-smokers. Among the healthy controls, smokers scored 6.88 ± 4.85 compared with 6.12 ± 3.85 for non-smokers (p < 0.05). Patients with schizophrenia showed a missing teeth (MT) score of 9.10 ± 8.56 compared with 5.38 ± 5.14 in control patients. MT scores increased significantly with age and with smoking in both groups of patients (p < 0.05). Patients with schizophrenia showed a filled teeth (FT) score of 1.38 ± 2.70 compared with 2.34 ± 3.48 in control patients. FT differences in gender and smoking habits between patients with schizophrenia and healthy control subjects were statistically significant (p < 0.05). This data, along with the DT scores, suggests that patients with schizophrenia have extensive untreated dental disease. CONCLUSIONS: Patients with schizophrenia constitute a high risk population for dental health. This group showed a greater prevalence of decayed and missing teeth and more extensive treatment needs.

RESUMO

Roughness and topographical features are the most relevant of the surface properties for a dental implant for its osseointegration. For that reason, we studied the four surfaces more used in titanium dental implants: machined, sandblasted, acid etching and sandblasted plus acid etching. The roughness and wettability (contact angle and surface free energy) was studied by means 3D-interferometric microscope and sessile drop method. Normal human gingival fibroblasts (HGF) were obtained from small oral mucosa biopsies and were used for cell cultures. To analyze cell integrity, we first quantified the total amount of DNA and LDH released from dead cells to the culture medium. Then, LIVE/DEAD assay was used as a combined method assessing cell integrity and metabolism. All experiments were carried out on each cell type cultured on each Ti material for 24h, 48h and 72h. To evaluate the in vivo cell adhesion capability of each Ti surface, the four types of discs were grafted subcutaneously in 5 Wistar rats. Sandblasted surfaces were significantly rougher than acid etching and machined. Wettability and surface free energy decrease when the roughness increases in sand blasted samples. This fact favors the protein adsorption. The DNA released by cells cultured on the four Ti surfaces did not differ from that of positive control cells (p>0.05). The number of cells per area was significantly lower (p<0.05) in the sand-blasted surface than in the machined and surface for both cell types (7±2 cells for HGF and 10±5 cells for SAOS-2). The surface of the machined-type discs grafted in vivo had a very small area occupied by cells and/or connective tissue (3.5%), whereas 36.6% of the sandblasted plus acid etching surface, 75.9% of sandblasted discs and 59.6% of acid etching discs was covered with cells and connective tissue. Cells cultured on rougher surfaces tended to exhibit attributes of more differentiated osteoblasts than cells cultured on smoother surfaces. These surface properties justify that the sandblasted implants is able to significantly increase bone contact and bone growth with very good osseointegration results in vivo.

RESUMO

INTRODUCCIÓN: En la actualidad, la implantología oral constituye una modalidad terapéutica en el tratamiento prostodóncico de los pacientes mayores edéntulos totales. El estudio muestra la evaluación del tratamiento con sobredentaduras mandibulares mediante la carga precoz de implantes dentales. MÉTODOS: Treinta pacientes edéntulos totales fueron tratados con 60 implantes con superficie arenada y grabada Galimplant(R) en la mandíbula para su rehabilitación prostodóncica con sobredentaduras. Dos implantes fueron insertados en cada paciente. Los implantes fueron cargados funcionalmente tras un periodo de tiempo de 6 semanas con retenedores de fricción. Los hallazgos clínicos (implantológicos y prostodóncicos) se han seguido durante al menos 24 meses. RESULTADOS: Los resultados indican una supervivencia y éxito de los implantes del 98,3%. Durante el periodo de cicatrización libre de carga funcional, se perdió un implante por movilidad. La pérdida de hueso marginal media fue de 0,4 mm (0-1,1 mm). El 100% de los pacientes fueron tratados mediante una sobredentadura implantorretenida con anclajes de fricción. En cuatro pacientes se realizaron cambios en los componentes plásticos de los ataches. El seguimiento clínico medio fue de 40,8 meses (24-60 meses). CONCLUSIONES: Los resultados del presente estudio indican que la rehabilitación prostodóncica mediante la carga precoz con sobredentaduras con implantes de los pacientes edéntulos mandibulares representa una terapéutica implantológica con éxito


INTRODUCTION: Today, oral implantology constitute a therapeutic modality in the prosthodontic treatment of totally edentulous patients. This study reports the evaluation of treatment with overdentures in the mandible by early loading of dental implants. METHODS: 30 edentulous patients were treated with 60 Galimplant(R) sand-blasted and acid-etched surface implants for prosthodontic rehabilitation with overdentures in the mandible. Two implants were inserted in each patient. Implants were loaded after a healing free-loading period between 6 weeks with locator attaches. Clinical findings (implant and prosthodontics) were followed during at least 24 months. RESULTS: Clinical results indicate a survival and success rate of implants of 98,3%. One implant was lost during the healing period. Media marginal bone loss was 0.4 mm (0-1.1 mm). 100% of patients were treated with overdentures retained with 2 implants with locator attaches. Changes in plastic components of attaches were reported in 4 patients. The media follow-up was of 40.8 months (24-60 months). CONCLUSIONS: Clinical results of this study indicate that prosthodontic rehabilitation in the mandible of edentulous patients with early loading of overdentures supported by implants is a successful implant treatment
