the use of multiple implants in the same jaw requires a detailed knowledge of abutment angulation. the position and angulation of the abutments play an important role in treatment planning and fabrication of the custom tray. therefore diagnostic casts that contain cover screws may cause problems during implant therapy. the current article describes a technique for making a preliminary cast with...

INTRODUCTION Implant-supported prostheses have to overcome a major difficulty presented by the morphology and esthetics of peri-implant tissues in the anterior sector. Diverse therapeutic techniques are used for managing the mucosa adjacent to the implant and the most noteworthy is immediate/deferred fixed provisionalization. OBJECTIVES In vitro testing of strength and deformation of implant ...

Background and Aim: Oral bacteria can proliferate in the implant-abutment interface (IAI) and cause inflammation in the peri-implant tissues and adjacent bone. This study aimed to assess the effect of zirconia and titanium abutments on the microleakage of the IAI under oblique cyclic loading conditions. Materials and Methods: In this in-vitro study, 12 implant-abutment assemblies with zirconia...

Implant restoration in the esthetic zone can present many challenges for the clinician. Patient and clinician demands for implant restorations with better esthetics have led to the introduction of ceramic abutments. With this introduction, questions have arisen regarding the properties of ceramic materials and their use in the fabrication of implant abutments. This issue of Report 011 Prosthodo...

PURPOSE The aim of this study was to examine the bending moments and fracture patterns of different zirconia abutments with internal implant-abutment connections after static loading and to compare their bending moments to those of internally connected titanium abutments. MATERIALS AND METHODS Three types of customized zirconia abutments (Straumann CARES abutments/Straumann BL implants [T1], ...

BACKGROUND In cement-retained implant-supported restoration it is important to gain adequate retention of definitive restoration as well as retrievability of prosthesis. The surface of the abutment, alloy of the restoration and the type of cement used influences the retention of the restoration. There is a need to analyze the influence of surface modifications of abutments on the retentive capa...

STATEMENT OF PROBLEM The clinical outcomes of anterior implant abutments are not well reported. Purpose of the Study To systematically review the existing literature to identify survival, mechanical, biological, and esthetic outcomes of anterior implant abutments. MATERIAL AND METHODS An electronic search was performed using PubMed/MEDLINE with specific search terms and predetermined criteria...
