RESUMEN

Abstract Objective: To perform an in vivo evaluation on the agreement between measurements of working length obtained by conventional radiographic examinations and an apex locator in deciduous teeth with or without root resorption. Material and Methods: Nine canals of teeth from children ranging from 3 to 5 years old were selected. Endodontic access was performed with a spherical diamond tip, the pulp was removed with Kerr-type steel files, and the canal was irrigated with 1% sodium hypochlorite. A file, compatible with the channel gauge, was then used to measure the length of the root canal with the apex locator. Conventional radiographs were also performed and, using a millimeter endodontic ruler, the length of the canal was determined. The differences between the measurements obtained between the two methods were analyzed using the Student's t-test. Results: The mean canal length for conventional radiography was 9.83 mm and 9.67 mm for the apex locator. The results of this study did not show significant differences (p=0.641), independent of the presence or absence of physiological root resorption. Conclusion: The similarity in measurements obtained with X-ray or an apex locator indicates that it is not necessary to use X-rays as a complement to obtain the working length. The use of the apex locator can provide a quicker treatment, reducing the clinical time and stress of the child.

RESUMEN

Abstract Objective: To evaluate the cephalometric norm for Saudi sample by Ricketts analysis (RA). Material and Methods: In this cross-sectional study, cephalometric radiographs were taken for 500 samples. The subjects included 250 males and 250 females. The ages of the subjects ranged from 18-30years. The criteria of selection were based on Class I incisor relationship, no skeletal abnormality and no previous orthodontic treatment. Lateral cephalometric radiographs were taken, traced and digitized by SPSS software, according to RA. An independent t-test was used to test the level of significance between genders. Results: Significant disparities found between Saudi males and females in dental and soft tissue measurements. The result showed that the distal position of the maxillary first molar to pterygoid vertical plane (U6 to Ptv) measurement was highly significantly greater (p<0.001) in Saudi males than females. Lower incisor to A-Pog (L1 to A-Pog) and lower lip to E plane was significantly longer (p<0.05) in Saudi males than females. Other measurements had no significant difference between Saudi males and females. Conclusion: The craniofacial morphology of the Saudi males was different from Saudi females using Ricketts analysis. This study will help the clinicians to diagnosis and treatment planning of orthodontic and orthognathic patients.

RESUMEN

Abstract Objective: To verify the concordance in the evaluation of the apical limit of obturation (ALO) in filled root canals of primary teeth between digital and visual methods. Material and Methods: Twenty periapical radiographs of endodontically treated primary teeth were digitalized and evaluated by an endodontics specialist (E1), a PhD pediatric dentist (E2), and a MSc general dentist (E3). Calibrated evaluators (Kappa = 1.00) analysed the images in a light-isolated environment two times (D1 and D2) with a one-week interval between evaluations. ALO scores were categorized as overfilled, flush-filled and underfilled. Results: The intra-rater reliability between methods was 0.82 (D1) and 0.75 (D2) for E1, 0.93 (D1 and D2) for E2, and 0.94 (D1 and D2) for E3. Inter-rater reliability ranged from 0.71 (E1 × E3) and 1.00 (E1 × E2) for the visual method to 0.76 (E1 × E3) and 0.88 (E1 × E2) for the digital method. Spearman correlation coefficients showed a similar ranking among the evaluators. There was greater disagreement among the underfilled and ideal scores. For all evaluators, the digital method favoured the identification of the ideal score. Conclusion: Both methods are suitable for the determination of the ALO of filled primary teeth and can be used in clinical practice.

RESUMEN

Introducción: La radiología oral y maxilofacial (RMF) es la disciplina encargada del uso de rayos X y otros tipos de radiación para el diagnóstico de enfermedades y condiciones del área maxilofacial. El propósito de la presente revisión es analizar el aporte de la RMF al diagnóstico clínico. Revisión: Las legislaciones nacionales suelen establecer requisitos para autorizar el uso e instalación de equipos generadores de radiaciones ionizantes, sin embargo, falta regulación sobre la responsabilidad del diagnóstico radiográfico. Por esto, es necesario aplicar consideraciones éticas y principios de protección radiológica que garanticen el uso responsable de los exámenes radiográficos. Debiera existir una persona responsable del diagnóstico radiográfico, que debe ser un odontólogo con conocimientos en interpretación radiográfica y cursos de educación continua en RMF. La solicitud y toma radiográfica son acciones fundamentales que contribuyen a que el responsable del diagnóstico radiográfico realice uno correcto. La RMF actualmente es reconocida como especialidad en más de 50 países, sin embargo, existe la necesidad de reconocimiento en otros países. Debido a su formación profesional, la existencia de especialistas en RMF contribuye a mejores diagnósticos radiográficos, con el consecuente impacto en el diagnóstico clínico y tratamiento del paciente. Conclusiones: La RMF es una disciplina fundamental para determinar el diagnóstico clínico del paciente. Para que los exámenes radiográficos usados aporten al clínico tratante a brindar la mejor atención al paciente, es fundamental que estos exámenes cuenten con un correcto y completo diagnóstico realizado por un profesional con entrenamiento y conocimientos en RMF, idealmente especialista en RMF


Introduction: Oral and maxillofacial radiology (MFR) is the discipline that deals with the use of X-rays and other kinds of radiation for the diagnosis of diseases and conditions of the maxillofacial region. The aim of the present review is to analyze the contribution of MFR to the clinical diagnosis. Review: National laws usually establish the requirements to authorize the use and installation of ionizing radiation generating equipment, nevertheless, there is a lack of regulation regarding the responsibility of the radiographic diagnosis. Because of this, it is necessary to apply ethical considerations and principles of radiation protection to guarantee the responsible use of the radiographic examinations. There should be a person responsible of the radiographic diagnosis, who must be a dentist with knowledge in radiographic interpretation and with continuing education courses in MFR. The radiographic request and taking are fundamental actions that contribute the responsible of radiographic diagnosis to elaborates a correct diagnosis. Nowadays, MFR is recognized as a specialty in more than 50 countries, however, there is a need of its acknowledgment in other countries. Due to the MFR specialist training, his/her existence contributes to a better radiographic diagnosis, with the consequent impact on clinical diagnosis and patient treatment. Conclusions: MFR is a fundamental discipline for determining the clinical diagnosis of the patient. In order the radiographic exams contribute the treating clinician to offer the best clinical attention to the patient, it is fundamental these exams have a correct and complete radiographic diagnosis, performed by a professional with training and knowledge in MFR, ideally an MFR specialist

RESUMEN

OBJECTIVE: To compare the accuracy of computer monitor and smartphone screen for radiographic diagnosis of marginal gap. MATERIALS AND METHODS: Forty teeth with mesial-occlusal-distal inlays (each tooth with a perfect fit and a 0.4-mm marginal gap restoration) were imaged with a phosphor plate system. Original digital radiographs were exported and analyzed with two different methods: computer monitor and smartphone screen; for the last method, images were shared with WhatsApp. Three examiners assessed all radiographs (n = 160) for the presence of marginal gap by using a dichotomous scale (yes/no). Diagnostic performance of each examiner and viewing method was evaluated by means of sensitivity (Se), specificity (Sp), and overall accuracy (Ac). Difference between the frequencies of gap detection of each method was analyzed using the McNemar test. Intra- and inter-examiner agreements were calculated using kappa statistics. RESULTS: Intra- and inter-examiner agreements were ≥ 0.80 for both methods. Similar diagnostic performance was found for computer monitor (Se = 0.87-1; Sp = 0.8-0.97; Ac = 0.84-0.99) and smartphone (Se = 0.77-1; Sp = 0.87-1; Ac = 0.88-0.95) viewing methods. No statistically significant differences in the frequency of gap detection were observed between the methods (P > 0.05). CONCLUSION: Diagnostic accuracy of smartphone screens was similar to that of computer monitor for marginal gap detection. CLINICAL RELEVANCE: Smartphones are becoming a common daily tool. In this sense, it might be an important new aid in Dentistry, including radiographic evaluation, which could benefit patients and dentists.

RESUMEN

Objective: To evaluate and compare the remineralization potential of a dentifrice containing bioactive glass and a topical cream containing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) in remineralizing artificial carious lesion on enamel. Material and Methods: Forty-five freshly extracted human permanent premolar teeth were selected. Samples were divided into three groups: GI - regular tooth paste without specific remineralizing agent; GII - tooth paste containing calcium sodium-phosphosilicate (novamin) and GIII - topical cream containing casein phosphopeptide-amorphous calcium phosphate. All the sound enamel samples were viewed under scanning electron microscope (SEM) to assess the topographical pictures of enamel surface and energy dispersing x-ray analysis (EDAX) was done to estimate quantitatively the amounts of mineral (calcium and phosphorous). The mineral content of calcium and phosphorus after demineralization in each group was noted. The samples were then subjected to SEM and EDAX. Results: GI does not show any increase in the calcium and phosphorus after applying toothpaste without any remineralizing agent but GII and GIII showed a net increase in calcium and phosphorous values after applying concern-remineralizing agents. Inter group comparison showed GIII yield higher net calcium and phosphorous values than GII. Conclusion: Two remineralizing agents showed remineralization potential on enamel surfaces. Casein phosphopeptide-amorphous calcium phosphate showed better remineralizing potential than calcium sodium phosphosilicate. Hence CPP-ACP can be considered as the material of choice in remineralizing early enamel carious lesions.

RESUMEN

Objective: To compare the effectiveness of conventional rotatory and piezosurgery technique for surgical removal of lower third molars. Material and Methods: Twenty patients with impacted lower third molars (with no acute symptoms) were divided into two groups (G1 and G2) and evaluated clinically and radiographically. They were allotted alternately into rotatory (G1) and piezotome (G2). Parameters assessed were the pain, swelling, trismus, comfort, analgesics consumed, the time taken for the procedure, intraoperative soft tissue damage and any other complications. Findings were then tabulated and analyzed. Results: Findings of pain, swelling, trismus, analgesics consumed and tissue damage were favorable in the piezosurgery group. However, the time taken for the procedure was significantly more as compared to the rotatory group. Post-operative trismus, values from the piezosurgery group were found to approach normality by day seven while in the rotatory group, a significant difference was found to exist up to day 14, suggesting that patients tend to return to normal function faster in the piezo group. Conclusion: Piezosurgery was found to be a good alternative to the conventional rotatory handpiece in select cases where extraction of the tooth could be carried out with minimal bone removal.

RESUMEN

Objective: To evaluate the presence of clinical and radiographic sequelae in primary teeth affected by dental trauma and its association with age at the time of trauma in children attended at a Public Higher Education Institution. Material and Methods: This is a longitudinal clinical study, in which 229 patients with history of dental trauma in primary teeth were examined, totaling 390 traumatized teeth. Relative frequency analysis was used, and for associations, the Chi-square test was used to verify the relationship of age at the time of trauma with variables such as type of trauma. Results: The most prevalent age group was over 24 months, and fall from own height as the main etiological factor; 71.0% of traumas had involvement of 2 teeth, 9.5% had history of anterior trauma and 66.6% of traumas involved supporting tissues. Regarding the type of injury to dental tissue, the most prevalent was enamel fracture (58.3%) and to periodontium, lateral dislocation (30.8%). Children older than two years had less trauma related to dental tissue (p<0.01), higher number of injuries to the periodontium (p=0.03); and most of them did not present extra-oral changes associated with trauma (p=0.01). During the 12- month period, 325 teeth were examined, and the most frequent clinical sequelae observed was crown discoloration. In the radiographic evaluation, inflammatory root resorption was the most prevalent. Conclusion: Children older than two years presented more injuries to the periodontium. After 12 months, the main clinical sequelae observed was enamel discoloration and the main radiographic sequelae was inflammatory root resorption.

RESUMEN

OBJECTIVES: Evaluate stray radiation to the operator, as represented by a plane within the significant zone of occupancy (SZO), produced by five models of hand-held intraoral dental X-ray devices (HIDXDs). METHODS: The stray radiation for five models of HIDXDs was measured, using an anthropomorphic tissue-equivalent head phantom as a scattering object. An ionization chamber was used to measure the air kerma (µGy) at 63 positions in a 160 cm high by 60 cm wide plane that was 10 cm behind the X-ray device, identified as being within the SZO. RESULTS: Based on the measured air kerma from stray radiation of five different HIDXDs, the estimated annual air kerma at all measured spatial positions was calculated. When calculated using a median air kerma of 0.8 mGy at the distal end of the cone, as typically required for digital image receptors, 1 the ranges for estimated annual air kerma in the SZO across the devices were 0.14-0.77 mGy for the median, 0.41-1.01 mGy for the mean, and 1.32-2.55 mGy for the maximum. Similarly, when calculated using a median air kerma of 1.6 mGy as typically required for D-speed film, 2 the ranges for estimated annual air kerma across the devices were 0.28-1.54 mGy for the median, 0.83-2.03 mGy for the mean, and 2.64-5.10 mGy for the maximum. CONCLUSIONS: From measured air kerma values of stray radiation in the SZO, estimated annual exposures to the operator for HIDXDs are expected to be greater than from conventional wall-mounted or portable devices activated from a protected area (at a distance or behind shielding). HIDXDs should therefore only be used when patient accessibility makes their use necessary and the use of a portable device on a stand or a wall-mounted device is not reasonably feasible. This approach would keep occupational radiation exposures of dental workers as low as reasonably achievable.

RESUMEN

This study aims to estimate the effective doses of dental X-ray devices under common scanning protocols. After putting TLDs in the Alderson Radiation Therapy Phantom, we exposed the phantom under common scanning protocols of three dental X-ray devices, namely CBCT, dental panoramic machine and intraoral round cone device. Then effective doses were calculated using the measured absorbed doses of organs and tissues. Tissue weighting factors recommended by the ICRP were adopted in the calculation. Effective doses under common scanning protocols of three Dental X-ray devices were obtained. The effective dose of dental CT was 0.20 mSv, and that of dental panoramic machine and intraoral radiography were 0.013 and 0.0050 mSv, respectively. The tissue absorbed doses of dental CT scan were 0.63 mGy of brain, 7.7 mGy of salivary glands, 8.7 mGy of thyroid and 4.0 mGy of the lens of the eye. The tissue absorbed doses from dental panoramic machine are 0.62 mGy of salivary glands and 0.25 mGy of thyroid. And finally the tissue absorbed dose of intraoral radiography was 0.80 mGy of salivary gland. Among the three dental X-ray devices studied, dental CBCT scan can cause much higher effective dose than the other two. Brain, salivary glands, thyroid and the lens of the eye are tissues receiving relatively higher absorbed doses.

RESUMEN

A indissociabilidade entre ensino, pesquisa e extensão é almejável para a oferta do ensino odontológico de qualidade. O estudo teve por objetivo determinar o perfil dos pacientes atendidos no Núcleo de Extensão/Pesquisa em Trauma Dental na Faculdade de Odontologia da Universidade Federal da Bahia. A pesquisa foi realizada com 86 pacientes de ambos os sexos, com idade entre 0 e 14 anos, apresentando lesões alvéolo-dentárias. Dois indivíduos já haviam sido atendidos anteriormente, retornando com novo trauma, totalizando 88 episódios de traumatismos. Os dados foram coletados de março de 2016 a janeiro de 2018 e as variáveis avaliadas foram idade e sexo do paciente, dentes afetados, tipo, etiologia, classificação e local onde ocorreu o trauma. Dos 86 pacientes 58,1% eram meninos e 41,9% meninas, com idades variando entre 1 e 14 anos, com média de 5,5 (± 3,7) anos. Na maioria dos casos um dente foi afetado e os incisivos centrais superiores foram os mais atingidos. Nos dentes decíduos a subluxação foi o trauma mais frequente nos tecidos de suporte e a fratura coronária com exposição pulpar nos tecidos dentais. Nos dentes permanentes a avulsão foi o trauma mais frequente nos tecidos de suporte e as fraturas do esmalte e da dentina nos tecidos dentários. Foi possível caracterizar o perfil dos pacientes que foram tratados com lesões dentárias no projeto, permitindo aos cirurgiões-dentistas conhecer a população de risco da região, as principais causas e os traumas mais frequentes (AU).


The inseparability between teaching, research and extension is desirable for the provision of quality dental education. This study determined the profile of patients assisted at the Extension/Research Unit in Dental Trauma at the Dental School of UFBA. The study was conducted on 86 patients of both genders, aged 0 to 14 years, presenting dentoalveolar lesions. Two individuals had already been previously treated and returned with a new trauma, adding up to 88 episodes of trauma. Data were collected from March 2016 to January 2018 and the variables evaluated were age and gender of the patient, affected teeth, type, etiology, classification and place where the trauma occurred. Among the 86 patients, 58.1% were boys and 41.9% girls, with age ranging from 1 to 14 years with mean of 5.5 (± 3.7) years. In most cases one tooth was affected, and the upper central incisors were the most affected. In primary teeth, subluxation was the most frequente trauma in supporting tissues and coronal fracture with pulp exposure in dental tissues. In permanent teeth, avulsion was the most frequente in supporting tissues and enamel and dentin fractures in dental tissues. It was possible to characterize the profile of patients treated with dental injuries in the project, enabling the dentists to know the risk population of the region, the main causes and the most frequent traumas (AU).

RESUMEN

O cisto dentígero é o mais comum dos cistos odontogênicos, com sua gênese a partir da separação do folículo da coroa de um dente incluso, sendo comumente encontrado nos terceiros molares e caninos superiores. Apresentam-se principalmente em jovens, de forma assintomática, podendo gerar assimetria facial. Seu diagnóstico é radiográfico e histopatológico, e seu tratamento clássico é feito através da enucleação, com o possível auxílio da marsupialização através da descompressão. O presente relato descreve paciente do sexo masculino, 14 anos, com queixas de aumento de volume e deformidade facial. A hipótese diagnóstica de cisto dentígero confirmou-se após a biópsia-marsupialização, com melhora radiográfica após nove meses, quando foi feita a enucleação total. Após 5 anos da segunda intervenção, o paciente apresentou total neoformação ossea (AU).


Dentigerous cyst is the most common type of odontogenic cyst. It is originated from the separation of crown follicles of an unerupted tooth and is usually found in third molars or superior canines. They are present mainly in young people, asymptomatically, however may cause facial asymmetry. Its diagnosis can be found through radiographic examination as well as oral histopathological diagnosis. Its classic treatment is performed through enucleation, with possible use of marsupialization through decompression. The present report describes the clinical case of a male patient, 14 years old, with complaints of increased volume and facial deformity. The diagnostic hypothesis of dentigerous cyst was confirmed after the biopsy- marsupialization with evidence of radiographic improvement after nine months, when total enucleation was performed. After five years following the second intervention, patient presented total bone neoformation (AU).

RESUMEN

O presente relato de caso tem como objetivo demonstrar a relevância da tomografia computadorizada de feixe cônico (TCFC) como ferramenta útil no diagnóstico de canais parcialmente mineralizados e discutir a limitação clínica que uma anatomia atípica impõe. Paciente do sexo feminino, 53 anos de idade, foi encaminhada para tratamento endodôntico do dente 27, o qual apresentava acesso apenas aos canais palatino (P) e mésio-vestibular (MV). Além destes dois canais já acessados, a TCFC identificou a presença dos canais disto-vestibular (DV) e mésio-palatino (MP). Com o uso do microscópio operatório (MO) e por meio de desgaste seletivo com pontas de ultrassom, foi possível localizar o canal DV, entretanto, o canal mésio-palatino (MP) não foi localizado. Em função da grande mineralização presente nos terços cervical e médio deste canal e do risco de perfuração eminente, seu acesso ficou impossibilitado. A TCFC é um recurso auxiliar na Endodontia, sendo indicada para os casos endodônticos complexos onde os benefícios de seu uso superem os seus riscos. Embora a TCFC forneça imagens com maior número de detalhes e informações sobre complexidade anatômica presente, ainda assim existem limitações clínicas que são intransponíveis mesmo com o auxílio de recursos como ultrassom e microscópio operatório, o que demonstra, mais uma vez, o quanto a complexidade anatômica representa um desafio constante para o sucesso endodôntico (AU).


The present case report aims to demonstrate the relevance of cone-beam computed tomography (CBCT) as a useful tool in the diagnosis of partially mineralized canals and to discuss the clinical limitation that atypical anatomy imposes. A 53-year-old female patient was referred to endodontic treatment of tooth 27, which had access only to the palatal (P) and mesiobuccal (MB) canals. In addition to these two root canals which had already been accessed, the TCFC identified the presence of vestibular canal (DV) and mesiopalatal canal (MP). Using the operative microscope (MO) and through selective wear with ultrasound tips, it was possible to locate the DV canal, however the MP canal was not found. Due to the great mineralization present in the cervical and middle thirds of this canal and the risk of imminent perforation, it was impossible to access it. Cone-beam computed tomography (CBCT) is an auxiliary resource in Endodontics and is indicated for complex endodontic cases in which the benefits of its use outweigh its risks. Although the CBCT provides images with greater detail and information on anatomical complexity, there are still clinical limitations that are insurmountable even with the aid of resources such as ultrasound and operative microscope, which demonstrates how much anatomical complexity represents a constant challenge for endodontic success (AU).

RESUMEN

As fraturas do arco zigomático são geralmente causadas por trauma direto e refletem prejuízos estéticos e funcionais, devendo ser realizado o correto diagnóstico por meio de exame clínico e radiográfico para realizar o tratamento adequado e evitar a presença de sequelas pós-traumáticas. O objetivo desse trabalho é relatar um caso de fratura isolada de arco zigomático, descrever os meios de diagnóstico e tratamento fechado desse tipo de fratura. Paciente HVS, gênero masculino, 38 anos, vítima de agressão física compareceu ao serviço de Cirurgia e Traumatologia Bucomaxilofacial da UFBA/OSID por meio da emergência do Hospital Geral do estado (Salvador/BA) há aproximadamente uma hora após o trauma. Foi realizada a antissepsia com iodo tópico, anestesia local superficial e incisão cutânea com lamina de bisturi nº 15. Após o acesso, realizou-se a introdução do gancho de Barros e redução fechada da fratura. Paralelamente ao relato, foi realizada uma pesquisa na literatura científica para embasar os métodos e técnicas utilizados no diagnóstico e tratamento. Observou-se, então, a partir do caso clínico que é possível reduzir fraturas isoladas de arco zigomático sob anestesia local com acesso próximo à fratura para redução fechada a fim de evitar aumento da morbidade de procedimentos e reduzir a oneração ao serviço público (AU).


Fractures of the zygomatic arch are usually caused by direct trauma and reflect aesthetic and functional damages, and the correct diagnosis must be made by means of clinical and radiographic examination in order to carry out the appropriate treatment and avoid the presence of post-traumatic sequelae. The objective of this work is to report a case of isolated fracture of the zygomatic arch, to describe the means of diagnosis and closed treatment of this type of fracture. Patient HVS, male gender, 38 years old, victim of physical aggression attended the Service of Oral and Maxillofacial Surgery and Traumatology of UFBA/OSID through the emergency of the state general hospital (Salvador/Bahia) approximately one hour after the trauma. Antissepsis was performed with topical iodine, superficial local anesthesia, and cutaneous incision with scalpel blade nº 15. After the access was performed the introduction of the Barros hook and closed reduction of the fracture. Parallel to the report, it has done a research in the scientific literature to support the methods and techniques used in diagnosis and treatment. It is observed from the clinical case that it is possible to reduce zygomatic arch fractures isolated under local anesthesia with close access to closed reduction fracture in order to avoid increased morbidity of procedures and reduce the burden on the public service (AU).

RESUMEN

Apesar da vasta literatura científica e das novas tecnologias, substituir elementos na região maxilar anterior continua sendo um grande desafio estético quando utilizamos a terapia com implantes osseointegrados. Este artigo relata um caso clínico em que um paciente do sexo masculino, 27 anos, que apresentava agenesia dos dois incisivos laterais superiores, após tratamento ortodôntico, teve os elementos substituídos por implantes osseointegrados. Regeneração tecidual guiada (RTG) utilizando osso bovino desproteinizado em conjunto com uma membrana de colágéno natural foi necessária para compensar defeitos ósseos vestibulares bilaterais. Imediatamente após o ato cirúrgico, duas coroas definitivas de cerâmica foram cimentadas. A proservação aos 18 meses demonstra boa estabilidade dos tecidos (AU).


Despite the vast scientific literature and new technologies, to replace elements in the anterior maxillary region remains a great aesthetic challenge when using osseointegrated implant therapy. This paper reports a clinical case of a male patient, 27 years old, who presented agenesis of two upper lateral incisors, and that had the elements replaced by osseointegrated implants after orthodontic treatment. Guided tissue regeneration (GTR) using deproteinized bovine bone in conjunction with a natural collagen membrane was required to compensate bilateral vestibular bone defects. Immediately after surgical procedure, two ceramic crowns were cemented. After 18-months follow-up, the case showed good tissue stability (AU).

RESUMEN

A Odontologia multidisciplinar atual exige cada vez mais do cirurgião dentista a necessidade de conhecer e indicar vários tratamentos aos pacientes. Atualmente, os implantes dentais são evidências nos tratamentos reabilitadores de pacientes edêntulos e pacientes com doenças periodontais avançadas. A instalação de implantes em pacientes periodontais não está contraindicada, desde que a doença esteja controlada e um esquema terapêutico corretamente adotado. Esses implantes são instalados imediatamente após as extrações e seguidos de carga imediata, devolvendo de forma rápida a estética e função ao paciente. O artigo a seguir descreve um relato de caso clínico de uma reabilitação total de maxila e mandíbula de um paciente portador de doença periodontal crônica. Foram extraídos 20 elementos dentais, seguidos de instalação de 6 implantes na maxila e 4 implantes na mandíbula, os mesmos foram carregados imediatamente com duas próteses fixas provisórias em resinas e, após o período de osseointegração de 4 meses, confecção de um protocolo superior em zircônia e protocolo inferior em resina de forma definitiva. O tratamento com implantes com carga imediata, além de devolver a estética e a segurança ao paciente, ainda melhora consideravelmente o pós-operatório, visto que o mesmo não necessita da utilização de uma prótese removível e, consequentemente, a redução de um passo cirúrgico, pois não exige nova cirurgia para a instalação de intermediários protéticos. Isso torna a cirurgia com carga imediata em pacientes periodontais totalmente viável, desde que um protocolo cirúrgico e terapêutico seja seguido (AU).


Currently, multidisciplinary Dentistry increasingly demands from the dental surgeon the need to know and indicate different treatments to patients. Dental implants are in evidence in the rehabilitation treatments of edentulous patients and patients with advanced periodontal diseases. The installation of implants in periodontal patients is not contraindicated, as long as the disease is controlled and a therapeutic regimen correctly adopted. These implants are installed immediately after extractions and followed by immediate loading, returning quickly aesthetics and function to the patient. The following paper describes a clinical case report of a total maxilla and mandible rehabilitation of patient with chronic periodontal disease. Twenty dental elements were extracted, followed by the installation of 6 implants in the maxilla and 4 implants in the mandible, they were immediately loaded with 2 temporary fixed resin prostheses and after the period of osseointegration of 4 months, and superior protocol in zirconia and inferior protocol in resin were performed definitively. Treatment with implants with immediate loading besides returning the aesthetics and bringing back security to the patient, still considerably improves the postoperative, since it does not need the use of a removable prosthesis and, consequently, there is reduction of a surgical step, because it does not require a new surgery to prosthetic intermediates installation. This makes immediate loading surgery on periodontal patients fully viable, as long as surgical and therapeutic protocol is followed (AU).
