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.

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.

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.

Abstract Background Objective of this study was to assess postoperative morbidity and mortality as well as recurrence-free and overall survival in patients with thymic malignancies and pleural dissemination undergoing surgical cytoreduction and hyperthermic intrathoracic chemotherapy (HITOC). Methods Retrospective study between September 2008 and December 2017 with follow-up analysis in May 2018. Results A total of 29 patients (male: n = 17) with thymic malignancies and pleural spread (primary stage IVa: n = 11; pleural recurrence: n = 18) were included. Surgical cytoreduction was performed via pleurectomy/decortication (P/D; n = 11), extended P/D (n = 15), and extrapleural pneumonectomy (EPP; n = 3). These procedures resulted in 25 (86%) patients with macroscopically complete (R0/R1) resection. Intraoperative HITOC was performed for 60 minutes at 42°C either with cisplatin (100 mg/m2 body surface area [BSA] n = 8; 150 mg/m2 BSA n = 6; 175 mg/m2 BSA n = 1) or with a combination of cisplatin (175 mg/m2 BSA)/doxorubicin (65 mg; n = 14). Postoperative complications occurred in nine patients (31%). Cytoprotective therapy resulted in lower postoperative creatinine levels (p = 0.036), and there was no need for temporary dialysis in these patients. The 90-day mortality rate was 3.4%, as one patient developed multiple organ failure. While recurrence-free 5-year survival was 54%, an overall 5-year survival rate of 80.1% was observed. Survival depended on histological subtype (p = 0.01). Conclusion Surgical cytoreduction with HITOC is feasible in selected patients and offers encouraging survival rates. The application of cytoprotective agents appears to be effective for the prevention of postoperative renal insufficiency.

ABSTRACTObjectives: The use of osseointegrated implants as an endoestal anchorage device to provide support for dental prostheses is a reliable and widely accepted treatment modality. The purpose of this study was to evaluate the clinical performance of non-submerged implants placed in the maxilla or in the mandible.Methods: A total of 146 International Team for Implantology (ITI) (Straumann AG, Waldenburg, Switzerland) implants were placed in 42 patients (20 women, 22 men, mean age 42). The cases were examined retrospectively in order to evaluate the clinical efficiency of non-submerged ITI implants and to determine the success rate of implant retained/supported prosthesis after a 5-year period. All implants were assessed clinically and radiographically on a yearly basis.Results: The 5-year cumulative success rates for maxillary and mandibular implants were 91.00% and 97.81%, respectively. The most common prosthetic complication was abutment accompanied by screw loosing (3.42%). Veneering material fracture was documented in only one patient.Conclusions: Within the limitations of the observation period and sample number, the present findings confirmed sufficient success and survival rates of ITI implants placed in mandible as well as implants placed in the maxilla after a 5-year period.
