Changes of Bone Tissue Surrounding HAP・Ti Implant Under Functional Lateral Loading

Influence of implant diameter on surrounding bone.

OBJECTIVES Implant osseointegration is dependent upon various factors, such as bone quality and type of implant surface. It is also subject to adaptation in response to changes in bone metabolism or transmission of masticatory forces. Understanding of long-term physiologic adjustment is critical to prevention of potential loss of osseointegration, especially because excessive occlusal forces le...

Changes in Bone Metabolisim Around Osseointegrated Implants Under Loading

Effect of Bone to Implant Contact Percentage on Bone Remodelling Surrounding a Dental Implant

Effects of callus and bonding on strains in bone surrounding an implant under bending.

Descriptions of the healing and adaptation of endosseous implants have been provided; however, their effects on mechanical parameters such as maximum and minimum principal strains, strain energy density, and maximum shear strain have not been addressed. Three linear, elastic, and partially anisotropic finite element models were generated to simulate the immediate postoperative period, time of p...

Effect of Single Off-Axis Implant Placement on Abutment Screw Stability Under Lateral Loading.

PURPOSE The aim of this study was to evaluate the effect of off-axis implant placement in relation to the prosthetic crown on abutment screw loosening under different directions of twisting moments. MATERIALS AND METHODS Twenty-one implant assemblies were divided equally into three groups (n = 7). Each assembly consisted of an internal-octagon implant measuring 4.1 × 12 mm (standard plus impl...
