Retrospective evaluation of the clinical performance of direct composite restorations using the snow-plow technique : up to 4 years follow-up
2019
Background To evaluate the clinical performance of direct composite restorations using the snowplow technique with up to 4 years of follow-up. Material and methods In this retrospective study, 101 class II composite restorations which were placed in permanent molars (n = 19) and premolars (n = 82) in 85 patients by the snowplow technique, were evaluated according to the modified USPHS criteria. A Kaplan-Meier analysis with a 95% confidence level was used to calculate the survival probability. Results Of the 101 teeth examined, tooth failure was identified in 8 teeth due to secondary caries (3%), marginal gap (2%), marginal discoloration (1%) and restoration breakdown (2%) which required rep…
Color Difference Thresholds in Dentistry
2015
Purpose The aim of this prospective multicenter study was to determine 50:50% perceptibility threshold (PT) and 50:50% acceptability threshold (AT) of dental ceramic under simulated clinical settings. Materials and Methods The spectral radiance of 63 monochromatic ceramic specimens was determined using a non-contact spectroradiometer. A total of 60 specimen pairs, divided into 3 sets of 20 specimen pairs (medium to light shades, medium to dark shades, and dark shades), were selected for psychophysical experiment. The coordinating center and seven research sites obtained the Institutional Review Board (IRB) approvals prior the beginning of the experiment. Each research site had 25 observers,…
Clinical outcomes of veneered zirconia anterior partial fixed dental prostheses: A 12-year prospective clinical trial
2019
Abstract Statement of problem Anterior veneered zirconia partial fixed dental prostheses (FDPs) have substituted for metal-ceramic to improve esthetics and biocompatibility. However, the material is susceptible to aging or hydrothermal degradation and to chipping of the feldspathic veneer. Whether these susceptibilities limit the clinical performance of anterior veneered zirconia FPDs is unclear. Purpose The purpose of this prospective clinical study was to analyze the mechanical and biologic behavior of zirconia partial FDPs in the anterior region over a 12-year follow-up period. Material and methods Twenty-seven 3- to 6-unit FDPs fabricated from zirconia veneered with feldspathic porcelai…
Four-year outcomes of full-arch fixed dental prostheses using CAD/CAM frameworks : a retrospective review of 15 cases
2018
The aim of this report is to analyze the clinical performance of 20 full-arch implant-supported titanium frameworks using CAD/CAM (Computer-Aided Design and Computer-Aided Manufacturing) technology. One hundred and four implants were placed in 15 patients using a one-stage protocol. After planning the location of all implants via 3-dimensional software (NobleClinician), 4-8 implants were placed in each edentulous arch based on anatomical measurements. Twenty edentulous arches were treated with full arch implant-supported fixed dental prostheses utilizing CAD/CAM milled titanium frameworks . All patients were followed up for 48±4 months. Clinical performance of the implants and restorations …
TCT-350 Safety and Performance of the Resorbable Magnesium Scaffold, Magmaris in a Real World Setting - First 400 Subjects at 12-month Follow-up of t…
2018
The aim of this registry is to investigate the clinical performance and long-term safety of the Resorbable Magnesium Scaffold (Magmaris) (BIOTRONIK AG, Buelach, Switzerland) in a real-world setting. Up to 2,054 subjects in up to 120 clinical sites in Europe, Asia, and Asia-Pacific countries will
Clinical outcomes of patients with diabetes mellitus treated with Absorb bioresorbable vascular scaffolds: a subanalysis of the European Multicentre …
2017
Background Data on the clinical performance of bioresorbable scaffolds in patients with diabetes mellitus (DM) are still limited. The present study reported 1-year clinical outcomes associated with the use of everolimus-eluting bioresorbable vascular scaffolds (Absorb BVS; Abbott Vascular, Santa Clara, CA) in DM patients. Methods and Results This was a subanalysis from the GHOST-EU (Gauging coronary Healing with biOresorbable Scaffolding plaTforms in Europe) multicenter retrospective registry including patients treated with Absorb BVS between November 2011 and September 2014. In this study, a comparative analysis stratified according to DM was performed. The primary endpoint was target lesi…
