Localization of the epulis in the area of the implants. Clinical case

Epulis is a benign neoplasm that is quite common in the practice of a dentist. It is a soft tissue formation on the peduncle that connects it to the gum. Sources of growth of epulis are most often the periodontium of the tooth, therefore, the neoplasm is very rarely found on the edentulous jaw or in the area of implants. Treatment of epulis is to eliminate the etiological factor, and excision of the formation together with the periosteum. In our practice, we first encountered an epulis that appeared in the area of previously installed implants. The excised mass was sent for pathological and histological examination, according to the results of which the conclusion was given: angiomatous epulis with a giant cell area with an expression.

Evaluation of the accuracy of a novel surgical guide for flapless dental implant placement for immediate loading in edentulous jaws

This study was designed to evaluate the accuracy of a novel computer-designed and selectively laser sintered surgical guide for flapless dental implant placement in the edentulous jaw. Fifty dental implants were placed in 11 patients with at least one totally edentulous jaw. Initially, cone-beam computed tomography (CBCT) was performed in each patient to define the virtual position of the dental implants based on the assessment of bone availability and the proposed dental prosthesis. After virtual planning, 3D surgical guides were printed using selective laser sintering. CBCT was repeated after the surgery, and the pre-and postoperative images were overlapped in the CAD software to compare the planned and actual positions of the dental implants using a one-sample t-test. The mean ± angular standard deviation between the long axes of the planned and final dental implant positions was 4.58 ±2.85 degrees; The linear deviation in the coronal position was 0.87 ± 0.49 mm and in the apical region of the dental implants was 1.37 ± 0.69 mm. These differences were statistically significant (p <0.001). The proposed modifications reduced the deviations, resulting in an improvement in the technique. We were able to place implants and temporary prostheses using the present protocol, taking into account the differences between the planned and final positions of the dental implants.

Prevalencia del Síndrome de Combinación y sus factores asociados en la Clínica de la Facultad de Odontología de la Universidad de Cuenca, periodo 2015-2016

BACKGROUND: The set of pathological changes in the stomatognathic system in the presence of a total maxillary prosthesis and a removable partial mandibular prosthesis has been described as the Combi-nation Syndrome. The main purpose of this study was to determine its prevalence and if features such as age, sex or type of mandibular edentulism are associated with the syndrome in the patients of the Odon-tologic Clinic of the of Faculty of Dentistry, Universidad de Cuenca during the academic period 2015-2016. METhODS: Cuantitative, cross sectional descriptive and correlational study. The sample consisted of 312 edentulous patients. The diagnosis of the syndrome in this study was determined by the presence of a minimum of three associated signs. We determine the prevalence of combiantion syndrome and the association between sex, age and edentulism type and combination syndrome. RESUlTS: The prevalence of combination syndrome is 21.8%. Adults 60 years or older (1.8 times higher probability) and patients who suffer from Kennedy class I partial edentulism (3.6 times higher probability than other types of edentulism), have a higher probability for developing the syndrome. CONClUSiON: The prevalence of CS was 21.8%, age and suffering from Kennedy class I partial edentulism should be considered as risk factors for developing the syndrome. KEYWORDS: PARTIAL DENTURE, COMPLETE DENTURE, PREVALENCE, EDENTULOUS JAW.

Opções terapêuticas para a reabilitação em mandíbulas atróficas: revisão da literatura

O aumento da população idosa nos consultórios odontológicos e o incremento da procura por tratamentos reabilitadores, faz com que os profissionais se especializem ainda mais para atender as necessidades desses pacientes. Os quais, na maioria das vezes possuem atrofia óssea, sendo que na parte posterior da mandíbula, a complexidade é maior, devido à aproximação do nervo alveolar e da possibilidade de fratura mandibular. Esta revisão de literatura tem como objetivo descrever as técnicas encontradas na literatura para a reabilitação das mandíbulas atróficas. Para isso, foi realizada uma busca de estudos nas bases de dados Scielo, Lilacs, PubMed e Science Direct. com os descritores “dental implants and jaw”, “dental implants and edentulous jaw”, “Rehabilitation”, “Graft” “Prostheses and Implants” com “and” e “or” como ferramentas integrativas/seletivas de busca. No estudo foi encontrado técnicas como a utilização de implantes curtos, próteses protocolo Branemark, reconstrução do rebordo com enxertos ósseos, lateralização do feixe vasculho-nervoso do alveolar inferior e distração osteogênica. Na comparação dos estudos, foi verificado que a utilização dos implantes curtos possui uma ligeira vantagem custo-benefício, por causar uma menor morbidade ao paciente e um menor custo do tratamento. Todavia, foi verificado que todas as técnicas possuem uma porcentagem bastante significativa de sucesso, sendo opções tratamento viáveis para pacientes com atrofia mandibular. Portanto, o profissional deve escolher o procedimento que se sente mais seguro, com base do seu conhecimento teórico e habilidade clínica, para proporcionar ao paciente uma melhor resolução para o tratamento.
