If a cement-retained implant prosthesis is placed on an abutment, excess cement should be minimized or removed to prevent periimplant inflammation. Various methods for fabricating an abutment replica have been introduced to maintain tissue health and reduce clean-up time. The purpose of this article is to present an alternative technique for fabricating an abutment replica with computer-aided d...

PURPOSE The aim of this investigation was to measure the temperature increase due to heat transferred to the implant-bone interface when the abutment screw channel is accessed or a metal-ceramic crown is sectioned buccally with diamond or tungsten carbide bur using an air rotor, with or without irrigation. MATERIALS AND METHODS Cobalt-chromium copings were cemented onto straight titanium abut...

Background and Aim: Maintaining the primary torque of the abutment screw is a common problem related to implant-supported restorations; a failure in this respect often leads to screw loosening. The abutment screw plays a critical role in the long-term stability of restorations. This study aimed to assess the effect of two abutment connection types with and without cyclic loading on removal torq...

Objective: To compare differences in caries and periodontal scores between removable partial denture wearers and non wearers; abutment with non-abutment teeth in the wearers and wearers with “satisfactory” to those with “unsatisfactory” dentures. Methods: Ninety-six partially dentate patients were included in this study. Teeth were examined for caries and periodontal diseases. Removable partial...

BACKGROUND Today, implants are placed using both non-submerged and submerged approaches, and in 1- and 2-piece configurations. Previous work has demonstrated that peri-implant crestal bone reactions differ radiographically under such conditions and are dependent on a rough/smooth implant border in 1-piece implants and on the location of the interface (microgap) between the implant and abutment/...

Background and Aim: Dental implants with angled abutments are often inserted in the anterior maxillary region due to the status of the residual ridge and aesthetic considerations. The purpose of this study was to assess stress and strain distributions in the premaxillary bone around dental implants by means of finite element analysis (FEA). Materials and Methods: Four three-dimensional (3D) fi...

Liquefaction-induced lateral spreading causes severe damage to the pile foundation of structures. Old structures that are not properly designed for liquefaction more vulnerable a strong earthquake. Many old piled abutments require remedial measure against spreading. This paper examines responses an abutment subjected liquefaction-induced and efficacy sheet reinforcement technique mitigate assoc...

Background and aims. Because of compromised angulations of implants, the abutments are sometimes prepared. The purpose of this study was to investigate the effect of removing one wall of the implant abutment on the retention of cement-retained crowns. Materials and methods. Four prefabricated abutments were attached to analogues and embedded in acrylic resin blocks. The first abutment was left ...
