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.

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.

AbstractSeveral authors have suggested that implants can be placed simultaneously with onlay bone grafts without affecting outcomes. Therefore, the purpose of this study was to answer the following clinical questions: (1) What are the outcomes of implants placed simultaneously with autogenous onlay bone grafts? And (2) is there a difference in outcomes between simultaneous vs delayed placement of implants with autogenous onlay bone grafts? Databases of PubMed, Embase, and Google Scholar were searched up to 15 November 2020. Data on implant survival was extracted from all the included studies (single arm and comparative) to calculate point estimates with 95% confidence intervals (CI) and pooled using the DerSimonian–Laird meta-analysis model. We also compared implant survival rates between the simultaneous and delayed placement of implants with data from comparative studies. Nineteen studies were included. Five of them compared simultaneous and delayed placement of implants. Dividing the studies based on follow-up duration, the pooled survival of implant placed simultaneously with onlay grafts after <2.5 years of follow-up was 93.1% (95% CI 82.6 to 97.4%) and after 2.5–5 years was 86% (95% CI 78.6 to 91.1%). Implant survival was found to be 85.8% (95% CI 79.6 to 90.3%) with iliac crest grafts and 95.7% (95% CI 83.9 to 93.0%) with intra-oral grafts. Our results indicated no statistically significant difference in implant survival between simultaneous and delayed placement (OR 0.43, 95% 0.07, 2.49, I2=59.04%). Data on implant success and bone loss were limited. Data indicates that implants placed simultaneously with autogenous onlay grafts have a survival rate of 93.1% and 86% after a follow-up of <2.5 years and 2.5–5years respectively. A limited number of studies indicate no significant difference in implant survival between the simultaneous and delayed placement of implants with onlay bone grafts. There is a need for randomized controlled trials comparing simultaneous and delayed implant placement to provide robust evidence.

The aim of the present study was to compare immediate (Im) versus delayed (De) placement of laser-treated implants surface with switching platform to confirm the predictability and performance of this type of implant. The implants were placed in pos exodontia and healed sites at the incisor, canine, premolar, and molar regions of the maxilla or the mandible. A protocol was prepared in which patient age, sex, implant length, diameter, and use of bone graft were recorded. The study included 44 GEASS Srl (Udine, Italy) implants with laser surface and morse taper connection, placed in 27 patients (mean age: 56 years; range: 25–80 years).The survival rates were 100% in the Im group and in the De group. The patients were followed for a minimum of 12 months. Implants with laser surface and morse connection presented when placed in fresh sockets showed similar results to implants placed in mature bone after 12 months of follow-up.

Objective. Adult granulosa cell tumors (AGCTs) represent 2%–5% of all ovarian malignancies. The aim of this study was to analyze clinical and pathohistological parameters and their impact on recurrence, overall, and disease-free survival in FIGO stage I AGCT patients. Methods. The tumor specimens analyzed in this retrospective study were obtained from a total of 36 patients with diagnosis of ovarian AGCT surgically treated at the Department of Gynecology, Rijeka University Hospital Centre, between 1994 and 2012. Clinical, pathological, and follow-up data were collected. Results. The mean age at diagnosis was 54.5 years with a range of 24–84. The majority of the patients, 30 (83%), were in FIGO stage IA, 3 (8%) in stage IC1, 1 (3%) in stage IC2, and 2 (6%) in stage IC3. During follow-up period (median 117.5 months, range 26–276), recurrence occurred in 4 patients (12%) with 2 deaths of the disease recorded. In univariate analysis, the 5-year survival rates were significantly shorter in patients with FIGO substage IC (p=0.019), with positive LVSI (p=0.022), with presence of necrosis (p=0.040), and with hemorrhage (p=0.017). In univariate analysis, the 5-year disease-free survival rates were significantly shorter in patients treated with fertility surgery (p=0.004), with diffuse growth pattern (p=0.012), with moderate and severe nuclear atypia (p=0.032), and with presence of hemorrhage (p=0.022). FIGO substage IC proved to be independent predictor for recurrence (OR = 16.87, p=0.015, and OR = 23.49, p=0.023, resp.) and disease-free survival (p=0.0002; HR 20.84, p=0.02) at the uni- and multivariate analyses. Conclusions. FIGO substage IC is predictive of recurrence and disease-free survival in patients with early-stage AGCTs. LVSI, presence of necrosis and hemorrhage, diffuse growth pattern, and nuclear atypia in AGCTs seem to be associated with overall and disease-free survival, so these pathological features should be taken into consideration when managing patients with AGCT.

Objectives: Dental implants are a prominent scientific breakthrough and are frequently applied for replacement of the missing teeth. From the clinicians’ point of view, long-term studies are essential to find out the predictability of dental implant systems. Materials and Methods: In this retrospective study, 1,626 patients who received 4,389 Dyna implants in a private office between 2013-2019 were evaluated. All statistical analyses were performed using SPSS 25 for Windows. P values less than 0.1 were considered significant for regression analysis. Results: Dyna implantts (4389) placed from 2013 to 2019 were evaluated in this study. One-hundred and thirty-three (3.03%) implants failed during the healing period or recall visits. Eighty-nine implants (2.03%) failed immediately and 44 (1%) failed after 3 months. Conclusion: The present study showed that the Dyna dental implant system had high implant survival, and it had all the survival criteria similar to world-class dental implant systems.

Abstract Background: Aim of this retrospective study was to document the long-term clinical efficacy of a surgical-prosthetic technique (Flat-one-Bridge) involving immediate restoration of both post-extractive and non-post-extractive implants supporting full-arch restorations. Methods: Implants were placed adapting the axis to the available bone. Flat definitive abutments were connected at surgery and never disconnected in order to compensate for eventual implants dis-parallelism. Bone grafting was performed when needed. Patients received a screw-retained provisional restoration within 48 hours of surgery and a final screw-retained prosthesis within one year. Results: Sixty-six patients received 494 implants distributed in 75 prosthesis. The median follow-up was 86 months (range 82-168 months). Only three implants failed at the last follow-up. Implant survival was 99.6%. Conclusion: The Flat-one-Bridge prosthetic protocol is a viable procedure with excellent long-term outcomes. No difference could be observed between post-extractive and non post-extractive implants in terms of clinical success.
