This study aimed to evaluate the survival rates of several external hexagon implants directly connected zirconia crowns after thermomechanical fatigue. The deformation hexagons and integrity were also evaluated. A monolithic crown (Y-TZP) four different dental (n = 10, N 40) mounted together embedded in polyurethane. specimens subjected cycling for 2.5 × 106 cycles, at 3.0 Hz frequency, 200 loa...

Prosthodontic treatment using dental implants is one of the solutions for partially and completely edentulous patients. The peri-implant area is colonized by a large variety of oral microbial complexes. Various prosthesis may provide means of mechanical attachment to the microflora; this in turn allows their aggregation and colonization. There exists a relationship between the peri-implant micr...

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 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], ...

OBJECTIVES Head and neck cancer patients who have lost facial parts following surgical intervention frequently require craniofacial implant retained facial prostheses for restoration. Many craniofacial implant patients require computed tomography and magnetic resonance imaging scans as part of their long-term follow-up care. Consequently removal of implant superstructures and peri-abutment tiss...

The aim of this review was to investigate the relationship between biofilm and peri-implant disease, with an emphasis on the types of implant abutment surfaces. Individuals with periodontal disease typically have a large amount of pathogenic microorganisms in the periodontal pocket. If the individuals lose their teeth, these microorganisms remain viable inside the mouth and can directly influen...

ABSTRACT Objective: The aim of this study was to compare the stress distribution in internal tapered connection implants with different adaptation geometries submitted oblique load simulation using Finite Element Analysis (FEA) method. Methods: Three implant-abutment assemblies were modeled by varying only diameter abutment body cone region. dimensions 4.0 mm and 13 length. Oblique loads 210 N ...
