PURPOSE Micromotion at the implant-abutment level has been reported to be a major determinant of longterm implant success, as technical problems ranging from screw loosening to screw fracture may occur as a consequence of excessive micromotion. MATERIALS AND METHODS Following published standards, implant-abutment assemblies were fixed in a universal testing machine at a 30-degree angle. A cyc...

Since Bra�nemark et al published the results of a 10-year study on osseointegration in 1977, dental implants have increasingly been used to replace missing teeth. The use of osseointegrated implants had become a successful procedure for the treatment of complete, partial edentulism, and single-tooth replacements in both the anterior and posterior regions of the mouth. Although improvements in m...

BACKGROUND: The inconsistency of the congruence surface implantabutment interface leads to impaired communication implant shaft with oral cavity, breakdown structure, including implant, and changes in occlusal relationships because axial displacement.
 AIM: This study aimed investigate degree displacement abutments made relative implants analogs. Specific tasks were as follows: (1) make va...

PURPOSE The objective of the present study was to investigate the effect on bone tissue healing patterns in 1-mm area treated in the transmucosal surface of the abutment in the tibia of rabbits. MATERIALS AND METHODS Forty-six abutments were divided into two groups: control group (CG) with 14 abutments with smooth surface and experimental group (EG) with 32 abutments presenting a 1-mm area of...

Purpose: Critical bending moment (CBM), the moment at which the external nonaxial load applied overcomes screw joint preload and causes loss of contact between the mating surfaces of the implant screw joint components, was measured with 2 types of implants and 2 types of abutments. Materials and Methods: Using 4 test groups of 5 implant-abutment pairs, CBM at the implant-abutment screw joint wa...

BACKGROUND The biologic width around implants has been well documented in the literature. Once an implant is uncovered, vertical bone loss of 1.5 to 2 mm is evidenced apical to the newly established implant-abutment interface. The purpose of this study was to evaluate the lateral dimension of the bone loss at the implant-abutment interface and to determine if this lateral dimension has an effec...
