BACKGROUND Although, dental implants have been a predictable option to support several types of restorations, mechanical problems are not uncommon. Retaining and abutment screw loosenings/fractures are one of the most common technical problems. AIM To present a step-by-step technique in order to remove a broken locater abutment screw fragment. MATERIALS AND METHODS A 56-year-old, edentulous...

This article illustrates a technique to solve the esthetic and functional challenges of restoring implants in situations with limited interocclusal clearance. As manufactured, some wide implants lack a gold cylinder abutment that attaches directly to the implant. Instead, an intermediate abutment is provided with the system. However, with limited interocclusal space, it is not feasible to resto...

BACKGROUND Against the background of increasing use of dental implants, and thus an increasing prevalence of implant-associated complications, a deeper understanding of the biomolecular mechanisms in the peri-implant tissue is needed. Peri-implant soft tissue is in direct contact with transmucosal dental implant abutments. The aim of this trial is to distinguish the biomolecular and histologica...

PURPOSE This study was conducted to assess the effect of using a double screw on the prevention of abutment screw loosening. MATERIALS AND METHODS Internal connected abutment with a single screw (IS), internal connected abutment with a double screw (ID), external connected abutment with a single screw (ES), and external connected abutment with a double screw (ED) groups were prepared (n = 10 ...

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,...

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...

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...

The seismic performance of integral abutment bridges (IABs) is affected by the interaction with surrounding soil, and specifically development forces in embankment-abutment soil-piles systems. In principle, these effects could be evaluated means highly demanding numerical computations that, however, can carried out only for detailed studies specific cases. By contrast, a low-demanding analysis ...
