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.

Abstract The goal of this retrospective study was to evaluate the survival rates of dental implants placed in sinuses grafted with a 50:50 composite ratio of autogenous bone and a natural flourohydroxyapatite (FHA) combined with platelet-rich plasma (PRP) using an immediate-load protocol. The authors hypothesized that a 50:50 composite ratio of FHA and autogenous bone combined with PRP would permit immediate loading without compromising implant survival rates. Eleven patients with bilateral partial edentulism of the posterior maxilla were enrolled in this retrospective study. Autogenous bone used in the graft procedure was harvested from the tibia of the left lower extremity. Each patient was grafted with a 50:50 composite ratio of autogenous bone and FHA. Membranes were not used to cover the lateral wall osteotomy site. Platelet-rich plasma was added to the graft material to accelerate and enhance bone regeneration. Four to 6 months after the grafting procedure, 37 hydroxyapatite-coated dental implants were surgically placed and immediately loaded between 72 hours and 5 days later with custom titanium abutments and acrylic provisional restorations placed out of functional occlusion. Six months later, definitive ceramometal restorations were cemented on to the custom abutments. Patients were observed over a 52-week period. The overall implant survival rate was 97.3%. Histologic and histomorphometric analysis of core samples revealed formation of new vital bone in different graft specimens ranging from 23% to 34%. In each core bone sample, 100% of the bone sample was determined to be vital. In the grafted maxillary sinus, the natural FHA combined with autogenous bone in a 50:50 composite ratio with PRP is a suitable graft material permitting immediate load without compromising implant survival rates while decreasing the overall healing time.

Objective: The aim of this study was to evaluate implant and prosthesis survival rates in full-arch rehabilitation supported by implants with platform-switched Morse taper connection submitted to immediate or delayed loading, after up to 5 years of follow-up. Material and Methods: Data was retrospectively collected from clinical records of patients who were treated by means of implant-supported full-arch rehabilitation. Survival rates of implants and prostheses were evaluated according to immediate or delayed loading. Results: The sample comprised 967 implants. Of those, 627 were submitted to immediate loading (IL) while 340 to delayed loading (DL). After a follow-up period of up to 5 years, the implant survival rate for IL was of 99.7% (622/627 implants) and 97.2% (333/340 implants) for DL. The overall implant survival rate was 98.8% (955/967 implants). Prosthesis survival rate was 100% (N = 178) for both groups. Significantly more implants in the DL group presented bone loss (p > 0.01), either greater or lower than 2 mm, during the follow-up period. Conclusion: Within their limits, the present results suggest that full-arch rehabilitation with platform-switched Morse taper connection implants can lead to surgical and prosthetic predictable outcomes. Moreover, immediate loading protocol seems to be a good option for the rehabilitation of fully edentulous patients, as it involves a shorter treatment time, which may lead to greater patient satisfaction.   Keywords Dental implants; Rehabilitation; Survival rate; Retrospective study.

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
