A common problem associated with single tooth implant restorations is abutment screw loosening. Manufacturers of implants have attempted to overcome this problem by incorporating antirotational design characteristics into their systems. Micromovement and torque levels required to loosen abutment screws for straight and angled antirotational screw-retained abutment/implant combinations from thre...

STATEMENT OF PROBLEM Screw loosening has been a common complication and still reported frequently. PURPOSE The purpose of this study was to evaluate abrasion of the implant fixture and TiN coated abutment screw after repeated delivery and removal with universal measuring microscope. MATERIAL AND METHODS Implant systems used for this study were Osstem and 3i. Seven pairs of implant fixtures,...

In this issue of the Journal, the case report by Garoushi et al illustrates an exciting technique for fixed tooth replacement that can be done chairside using a new class of dental material, fiberreinforced composite. This approach provides the patient with a cost effective treatment alternative that a clinician can choose to augment the traditional fixed prosthodontic approaches of porcelain f...

Abstract There are cases where the common approaches used to assess temperature loading effects may not be sufficient, especially in case of integral abutment bridges (IABs). In IABs, incorrect choice design result an unwanted tensional state bridge decks and additional loads on abutments. For post‐tensioned bridges, combined excessive loss tension cables due time‐dependent phenomena like relax...

Purpose To compare the failure events and incidence of complications of different abutment materials in anterior and posterior regions. Failure was defined as complete loss of the abutment requiring replacement by a new abutment. Materials and methods Electronic searches using PubMed/Medline and Google Scholar complemented with manual searches were performed with specific search terms. Search...

PURPOSE Microgaps at the implant-abutment interface allow for microbial colonization, which can lead to peri-implant tissue inflammation. This study sought to determine the marginal accuracy of three different implant-zirconium oxide (zirconia) abutment configurations and one implant?titanium abutment configuration. MATERIALS AND METHODS Three combinations of implants with custom-made zirconi...

OBJECTIVE This review aims to compare peri-implant tissue changes in terms of clinical and radiographic aspects of implant restoration protocol using one-time abutment to repeated abutment connection in platform switched implant. METHOD A structured search strategy was applied to three electronic databases, namely, Pubmed, Embase and Web of Science. Eight eligible studies, including seven ran...
