Introduction While contemporary prosthetic devices provide some restoration of function to individuals who have lost a limb, there are ongoing efforts to develop bio-integrated prostheses that would enhance functionality by providing motor control and sensory feedback. A critical step in the development of a bio-integrated prosthesis will be establishing longterm, secure fixation to the remnant...

The main objective of this research is to establish a connection between orthodontic mini-implant design, pull-out force and primary stability by comparing two commercial mini-implants or temporary anchorage devices, Tomas®-pin Perfect Anchor. Mini-implant geometric analysis quantification bone characteristics are performed, whereupon experimental in vitro test conducted. With the use CATIA (Co...

The state-of-the-art porous coatings become more and more popular in uncemented prostheses to make bone grow into implants for biological fixation. In this paper, graded cellular structures are proposed for uncemented prostheses to enhance stability on implant-bone interfaces. As an example study, the authors develop a new acetabular implant with gradient porosity for hip replacement. A gradien...

PURPOSE This study evaluated the initial stability of different implants placed above the bone level in different types of bone. MATERIALS AND METHODS As described by Lekholm and Zarb, cortical layers of bovine bone specimens were trimmed to a thickness of 2 mm, 1 mm or totally removed to reproduce bone types II, III, and IV respectively. Three Implant system (Brånemark System® Mk III TiUnite...

AIM To develop computer software to allow general dental practitioners and others to identify unidentified implants in patients' mouths using a range of criteria. METHODS Internet searches for implant manufacturing companies worldwide in all languages using terms: dental implants, dental implant manufacturers and dental implant companies. Once identified, all relevant information including im...

After exposing a submerged implant to the oral environment, bone loss occurs downwards along the implant body and stops at some predefined position. A current area of hot debate is the significance of the implant abutment interface and its influence on crestal bone level in relation to the first thread. In recent years, the microgap which exists at the connection between the implant body and th...

OBJECTIVES To explore the method of manufacturing an implant surgery template with a computer-aided design/computer-aided manufacturing (CAD/CAM) technique and evaluate its precision in clinical cases. METHODS Patients referred to the 2nd Dental Center of Peking University who were partially edentulous, were enrolled and scanned with cone beam computed tomography (CBCT). Diagnostic casts were...

The osseointegration and long-term success of bone-interfacing implants are dependent on mechanical stability of the implant relative to host bone during the early healing period. The geometric design of an implant surface may play an important role in affecting early implant stabilization, possibly by influencing tissue healing dynamics. In this study, we compared the early tissue healing resp...
