Retrospective study of treatment outcomes with implant-retained extraoral prostheses: Survival rates and prosthetic complications

This retrospective study was undertaken to determine survival rates and aesthetic outcomes of immediate placement of multiple implants at anterior maxilla sites. One hundred and eighteen implants placed in 39 patients (21 women and 18 men; average age 58.3 years) were immediately restored (24–72 h after placement). Aesthetic assessment, radiographic bone loss, and biological and prosthetic complications were evaluated. Data collection between 12 and 84 months (mean 32.2 ± 18) after final prosthetic installation revealed that no implants were lost, and that 106/118 (89.8%) implants had no more than 1.5 mm of bone loss by the end of the first year and an additional 0.2 mm for each successive year. The marginal bone loss was higher for extractions due to periodontitis compared to extractions due to caries (mean mesial loss of 1.37 mm vs. 1.01 mm, respectively, and mean distal loss of 1.37 mm and 0.99 mm, respectively, p = 0.001). The mesial papilla was present in 83/118 implants (70.3%), while the distal papilla was present in 76/118 implants (64.4%). The cervical metallic part of the abutment was exposed in 16/118 (13.5%) implants. There was a higher ratio of recessions and missing papillae in patients in whom the extractions were performed due to periodontal reasons. Within the limitations of the present study, aesthetic and radiographic parameters support immediate restoration of partially edentulous maxillae.

There have been no studies of implant-crown-retained removable partial dentures (IC-RPD) for the treatment of maxillary edentulism. The purpose of this study was to perform clinical and radiographic evaluations of implants in IC-RPD compared to implant overdentures (IOD) in maxillary edentulous patients. Twenty IC-RPDs with 74 splinted implant crowns and 18 IODs with 71 implants retained with magnet attachments were observed in 38 patients. We statistically analyzed survival rates and marginal bone loss (MBL) of implants based on multiple variables including first year pathologic condition, location of placed implant, age, and sex in both treatments. Patient reported oral measurements (PROMs) regarding functional/esthetic improvement after IC-RPD or IOD treatments and prosthetic complications were also statistically analyzed. After a median observation period of 47.1 months (up to 147 months), we observed 97.3% implant survival rates for IC-RPD and 70.4% for IOD (p < 0.001). Among variables, first year pathologic condition (p < 0.001) and sex (p = 0.027) influenced implant survival rates. The MBL of implants for IC-RPD and IOD groups at the final check-up were 1.12 ± 1.19 mm and 3.31 ± 1.71 mm, respectively (p < 0.001). In both groups, patients with peri-implantitis (p < 0.001) and patients older than 65 years (p = 0.029) showed significantly higher implant MBL regardless of treatment modality. Functional and esthetic satisfaction were significantly improved (p < 0.001) after both treatments. The IOD group showed more frequent prosthetic complications compared to the IC-RPD group. Within the limitations of a retrospective study, we concluded that RPD with few splinted implant crowns is a feasible alternative treatment modality for maxillary edentulous patients with anatomical limitations.

Main Complication

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

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.
