Serdar Yenigun, DDS, PhD/Pinar Ercal, PhD/Elif Ozden-Yenigun, PhD/Ahmet Bulent Katiboglu, PhD: Purpose: The aim of this study was to determine the effect solid (one-piece) and two-piece abutments on stress profile narrow implants with marginal bone loss. Materials Methods: Solid were connected a conical internal octagonÂconnection implant (3.3 mm in diameter, 10 length) restored single crown. Three-dimensional finite element analysis used simulate distribution models different levels resorption (0, 1, 2, 3 mm). design variables under increased scenarios, including abutment screw length assessed. Static loading applied mechanical response cortical trabecular bone. Results: Marginal dominated static conditions. A loss significantly values vicinity screw. Both designs displayed similar surrounding bone, but lower observed body abutments. more effective resultant stress, as longer screws reduced implants. Conclusion: magnitude is crucial parameter biomechanics behavior. As increases, around mastication forces may lead failure, regardless type.

Effect of Abutment Height Difference on Stress Distribution in Mandibular Overdentures: A Three-Dimensional Finite Element Analysis
Background and Aim: Implant-supported overdentures are a treatment option for edentulous patients. One of the important factors in determining the prognosis of overdenture treatment is to control the distribution of stress in the implant-bone and attachment complex. This study assessed the effect of implant abutment height difference on stress distribution in mandibular overdentures. Materials...
متن کاملEffect of Abutment Angulation and Material on Stress and Strain Distributions in Premaxillary Bone: A Three-Dimensional Finite Element Analysis
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...
