The purpose of this retrospective study was to determine survival and peri-implant marginal bone loss of short and ultra-short implants placed in the posterior mandible. A total of 98 patients received 201 locking-taper implants between January 2014 and January 2015. Implants were placed with a 2-stage approach and restored with single crowns. Clinical and radiographic examinations were performed at 3-year recall appointments. At that time, the proportion of implant survival by length, and variations of crestal bone levels (mean crestal bone loss and mean apical shift of the “first bone-to-implant contact point” position) were assessed. Significance level was set at 0.05. The total number of implants examined 36 months after loading included: 71 implants, 8.0 mm in length; 82 implants, 6.0 mm in length; and 48 implants, 5.0 mm in length. Five implants failed. The overall proportion of survival was 97.51%, with 98.59% for the 8.0-mm implants, 97.56% for the 6.0-mm implants, and 95.83% for the 5.0-mm implants. No statistically significant differences were found among the groups regarding implant survival (P = .73), mean crestal bone loss (P = .31), or mean apical shift of the “first bone-to-implant contact point” position (P = .36). Single-crown short and ultra-short implants may offer predictable outcomes in the atrophic posterior mandibular regions, though further investigations with longer follow-up evaluations are necessary to validate our results.

Objetivo: Avaliar diferentes métodos paliativos quanto a sua resolução, complicações e sobrevida em pacientes com tumor periampular irressecável. Materiais e métodos: Estudo retrospectivo com análise dos prontuários de pacientes com tumor periampular irressecável e que foram submetidos a procedimento paliativo no Hospital Municipal Dr José de Carvalho Florence nos últimos cinco anos. Resultados: O principal tumor periampular foi o de cabeça de pâncreas, com incidência de 94%, acometendo pacientes com média de 66 anos, sem preferência por sexo. Os procedimentos mais realizados foram derivação biliar e colocação de endoprótese através de colangiopancreatografia endoscópica retrógrada, apresentando sobrevidas de 586 e 56 dias, respectivamente. Conclusão: A coledocojejunostomia foi o procedimento mais realizado e apresentou menor tempo de internação e maiores sobrevida e tempo de permanência anictérico. Pneumonia foi a complicação mais frequente.  Palavras chave: Câncer pancreático, Colangiocarcinoma, Cuidados paliativos.  Objective: To evaluate different palliative methods concerning its resolution, complications and survival in patients with unresectable periampular tumor. Materials and methods: Retrospective study analysing records of patients with unresectable periampullary tumor and who underwent palliative procedure in the Hospital Municipal Dr José de Carvalho Florence in the past five years. Results: The main periampullary tumor was the head of the pancreas, with an incidence of 94%, affecting patients with an average of 66 years old, regardless of gender. The most common procedures were bypass and biliary stent, with survival rates of 586 and 56 days, respectively. Conclusion: Coledocojejunostomy was the procedure which was the most often performed and showed a shorter hospital stay and longer survival time and time without jaundice. Pneumonia was the main complication.  Keywords: Pancreatic cancer, Cholangiocarcinoma, Palliative care

Introduction: The aim of this retrospective study was to analyze the radiographic peri-implant bone loss of bone level implants and tissue level implants with a convergent neck in screw-retained single crowns and in screw-retained fixed partial prostheses, after two years of functional loading. Materials and methods: The sample was divided into two groups according to their type: Group I: supracrestal implants with convergent transmucosal neck; Group II: crestal implants. In each group we distinguish two subgroups according to the type of prosthetic restoration: single crowns and a three-piece fixed partial prosthesis on two implants. To quantify bone loss, parallelized periapical radiographs were analyzed at the time of implant placement and after two years of functional load. Results: A total of 120 implants were placed in 53 patients. After statistical analysis it was observed that for each type of implant bone loss was 0.97 ± 0.91 mm for bone level and 0.31 ± 0.48 mm for tissue level. No significant differences were found regarding the type of prosthesis and the location (maxilla or mandible) of the implants. Conclusions: Tissue level implants with a convergent transepithelial neck exhibit less peri-implant bone loss than bone level implants regardless of the type of prosthesis.

Clinical Records

This retrospective study evaluated the survival rate of short, sandblasted acid-etched surfaced implants with 6 and 8 mm lengths with at least 120 days of follow-up. Data concerning patient, implant and surgery characteristics were retrieved from clinical records. Sandblasted and acid-etched (SLA)-surfaced tissue-level 6 mm (TL6) or 8 mm (TL8) implants or bone-level tapered 8 mm (BLT8) implants were used. Absolute and relative frequency distributions were calculated for qualitative variables and mean values and standard deviations for quantitative variables. A Cox regression model was performed to verify whether type, length and/or width influence the implant survival. The cumulative implant survival rate was assessed by time-to-event analyses (Kaplan–Meier estimator). In all, 513 patients with a mean age of 58.00 ± 12.44 years received 1008 dental implants with a mean follow-up of 21.57 ± 10.77 months. Most implants (78.17%) presented a 4.1 mm diameter, and the most frequent indication was a partially edentulous arch (44.15%). The most frequent locations were the posterior mandible (53.97%) and the posterior maxilla (31.55%). No significant differences were found in survival rates between groups of type, length and width of implant with the cumulative rate being 97.7% ± 0.5%. Within the limitations of this study, the evaluated short implants are a predictable option with high survival rates during the follow-up without statistical differences between the appraised types, lengths and widths.
