PURPOSE Preparation of a one-piece dental implant abutment is often needed to achieve a proper emergence profile for a definitive restoration. However, this procedure may compromise osseointegration through the production of heat. The aim of this study was to measure heat production during implant abutment preparation with different volumes of water irrigation using a one-piece implant system. ...

INTRODUCTION Comparison of platform switched (PS), sloping shoulder, and regular implants on stress reduction in various bone densities with finite element analysis. MATERIALS AND METHODS A total of 12 three-dimensional finite element models were built to analyze the stress distribution model. Nobel Biocare 4.3 × 8 mm regular platform replace select implant with matching diameter easy abutmen...

Background. Since the misfit of crown has an important role in clinical performance of implant-supported prostheses, and due to the impact of the settling effect on misfit, the aim of this study was to investigate the impact of torque forces on the total lengths of narrow and short implant abutments in different internal implant‒abutment connections. Methods. In four different implant‒abutment ...

OBJECTIVES The objective of this work was to use finite element analysis to compare the effect of forces coming to bear on abutments 4.1 or 5.0 mm in diameter connected to a 5.0 mm implant (i.e. with or without platform switching). STUDY DESIGN A 3D CAD model of a 5 x 11.5 mm external hex implant was developed, complete with a connection screw and either of two abutments, one 4.1 and the othe...

Implant rehabilitation is a daily practice in dentistry, and patients often have heightened expectations regarding both the functional aesthetic outcome. Implant–abutment connection (IAC) involved long-term quality of rehabilitation. The use one-piece implants for fixing dentures may prevent mechanical biological implication implant–abutment interface, resulting better hard soft tissue maintena...

Aims: purpose of this study is to evaluate crestal bone reabsorption through prosthetic rehabilitation of mono or bi-edentulism in aesthetical sectors using non post-extractive implants with “one abutment – one time” method. Methods: 24 patients have been selected and randomized in two groups: PA group: 12 patients rehabilitated using provisional abutments and DA group: 12 patients rehabilitate...

Many clinicians prefer to install implant prosthetics by the screw-in method because they believe that this method allows for prosthesis retrievability. However, retrievability does not result from the prosthesis installation method, but relates to “Retrievability Features” created by the implant surgeon and enhanced by implant manufacturers. Unfortunately, these features are not free of cost o...

AIM The aim was to examine the technical quality of root fillings and periapical status of root-filled and nonroot-filled teeth restored with crowns and bridge retainers through a retrospective analysis of orthopantomographs (OPTGs) in an adult Turkish subpopulation. MATERIALS AND METHODS In this study, the digital OPTGs of adult patients between the ages of 20 and 70 who appealed to the Endo...

PURPOSE This retrospective study investigated the survival rate of 174 clasp-retained removable partial dentures (CR-RPDs) made at the Department of Prosthodontics of the Regensburg University Medical Center over a 25-year period (1984 to 2009). MATERIALS AND METHODS The study analyzed the frequency of and time to the fracture of clasps, connectors, or denture bases; the occurrence of caries ...
