Load transfer along the bone-dental implant interface.
In this paper the variation of normal and shear stresses along a path defined on the bone-dental implant interface is investigated. In particular, the effects of implant diameter, collar length and slope, body length, and the effects of four different types of external threads on the interfacial stress distribution are studied. The geometry of the bone is digitized from a CT scan of a mandibula...
متن کاملDental Implant Design and Biological Effects on Bone-Implant Interface
Although dental implants have become a predictable aspect of tooth replacement in prosthodontic treatment [1, 2, 3, 4, 5, 6], failures of up to 10% are still encountered. Furthermore these failures have been more associated with “soft” bone quality [7], 1985) such as encountered in the maxillary posterior area [8, 9, 10, 11, 12]. In a review article by Esposito et al [13], bone quality and volu...

متن کامل3D finite element non linear analysis on the stress state at bone-implant interface in dental osteointegrated implants.
PURPOSES The aim of the study was to assess by means a 3D finite element linear and non-linear analysis mechanical interaction between an implant-supported crown and surrounding tissues. MATERIALS AND METHODS A three-dimensional FEM model was developed. Four different material combinations for the abutment and the core were evaluated: Y-TZP - Y-TZP, Y-TZP - microhybrid composite, T - microhyb...
متن کاملNumerical study of effect of elastomeric stress absorbers on stress reduction in bone-dental implant interface
OBJECTIVE This paper focused on optimal stress distribution in the mandibular bone surrounding a dental implant and is devoted to the development of a modified Osteoplant® implant type in order to minimize stress concentration in the bone-implant interface. MATERIAL AND METHODS This study investigated 0.4 mm thick layers of two elastomeric stress barriers incorporated into the dental implant ...
