This double-blind randomized controlled trial with a crossover design analyzed the technical and clinical performance of three-unit monolithic ZrO2 implant-fixed dental prostheses (iFDPs), prepared using two complete digital workflows (Test-1, Test-2) and one mixed analog–digital workflow (Control). Each of the 20 study patients received three iFDPs, resulting in 60 restorations for analysis. The quality of the restorations was assessed by analyzing laboratory cross-mounting and calculating the chairside adjustment time required during fitting. All iFDPs could be produced successfully with all three workflows. The highest cross-mounting success rate was observed for the original pairing iFDP/model of the Control group. Overall, 60% of iFDPs prepared with Test-1 workflow did not require chairside adjustment compared with 50% for Test-2 and 30% for Controls. The mean total chairside adjustment time, as the sum of interproximal, pontic, and occlusal corrections was 2.59 ± 2.51 min (Control), 2.88 ± 2.86 min (Test-1), and 3.87 ± 3.02 min (Test-2). All tested workflows were feasible for treatment with iFDPs in posterior sites on a soft tissue level type implant system. For clinical routine, it has to be considered that chairside adjustments may be necessary, at least in every second patient, independent on the workflow used.

Abstract Introduction In 2013, the Attune® knee implant system was released as an updated prosthesis design, superseding the PFC Sigma®. Limited data exists regarding the early-to-midterm survival, functional and clinical benefits of the Attune®. The primary aim of this study was to compare functional outcome between the Attune® and PFC Sigma® at 3 years post-op. Method A single-centre, prospective cohort study of 110 patients, selected by propensity score matching, was conducted. Patient demographics, peri-operative care, clinical outcomes and functional scores were analysed to determine which prosthesis conferred a superior functional outcome. Results Median and mean increases in American Knee Society Score for the Attune® and Sigma® knees were 53 (26.9) and 43.6 (± 15.4) respectively (p = 0.307). Mean increase in Oxford Knee Scores were 21.8 (± 8.8) and 18.7 (± 8.8) for the Attune® and Sigma® respectively (p = 0.27, 95% CI -2.56 to 8.7). Mean and median increased range of movement was 11.8o (± 28) and 1.7o (± 13.5o) for the Attune® and Sigma® respectively (p = 0.05, 95% CI -0.015 to 20.2). Conclusions The Attune® knee system displays a significantly improved range of motion and a trend towards higher knee scores over a conventional implant at 3 years post-surgery, which may support use in future clinical practice.

Aim: The aim of this study was to evaluate the clinical performance of fiber-reinforced periodontal splints (FRSs) and adhesive bridges (FRBs) in treating anterior single-tooth defects. Methodology: Sixty-five patients who received FRSs and FRBs from 2001 to 2012 were recalled and evaluated clinically. The FRS and FRB restorations of the patients were clinically evaluated in terms of anatomical form, marginal adaptation, marginal coloration, secondary caries, and retention, according to the modified United States Public Health Service (USPHS) criteria. The current restoration statuses of the patients from 5 to 10 years post-treatment were photographed and recorded. Patient satisfaction level was assessed using a visual analogue scale (VAS), and periodontal pocket depth was measured. Clinical follow-up data were obtained and analyzed with the Chi-squared test (p<0.05). Results: When each of the modified USPHS criteria was compared with the baseline values, statistically significant differences were observed between the groups. There were statistically significant differences when the categories were evaluated according to initial values (p<0.05). When the clinical evaluation criteria were compared with each other, no statistically significant differences were found (p>0.05). While the most successful results were obtained in the FRB group, most of the restoration losses and repairs occurred in the FRS group. According to the data obtained, 38% of restorations were lost and all restorations had been intact for at least 5 years. All lost restorations were in FGS restorations. The recall rate was 49% (n=32). Twenty (62.5%) of 32 patients rated their satisfaction with the restorations as being between 90 and 100, 8 (25%) as being between 80 and 90, and 4 (12.5%) as being between 70 and 80 on the VAS scale. The pocket depths of the patients at 5- and 10-years post-restoration were 2.3–3.8 mm and 2.4–5.2 mm, respectively. Conclusion: Fiber-reinforced restorations performed due to the loss of anterior single teeth and periodontal tissue can serve patients clinically for at least 5 years. FGK and FGS restorations can be considered alternative treatments that can further delay the more expensive implant and prosthetic treatment options for years.   How to cite this article: Ünlü N, Altınbilek N, Velioğlu MS.
