Improvements in implant designs have helped advance successful immediate anterior implant placement into fresh extraction sockets. Clinical techniques described in this case enable practitioners to achieve predictable esthetic success using a method that limits the amount of buccal contour change of the extraction site ridge and potentially enhances the thickness of the peri-implant soft tissue...

Microleakage can occur at the abutment-implant (A-I) interface in osseointegrated implants and may cause malodor and inflammation of peri-implant tissues. The degree of microleakage at the A-I interface of 5 implant systems was comparatively assessed at varying closing torques. Using colored tracing probes driven by a 2-atm pressure system, the interface microleakage of Brånemark, Sulzer Calcit...

The aim of this study was to compare and evaluate strain distribution on dental implant, abutment, screw and crown virtual models in the posterior region. The analysis was performed by means of a 3D virtual model developed by the PRO-ENGINEER System (PRO-ENGINEER, PTC, Needham, MA, USA ) with an external butt joint (3i Implant Innovations, Palm Beach, Florida), square headed Gold Tite abutment ...

The properties of biomaterials, including their surface microstructural topography and their surface chemistry or surface energy/wettability, affect cellular responses such as cell adhesion, proliferation, and migration. The nanotopography of moderately rough implant surfaces enhances the production of biological mediators in the peri-implant microenvironment with consequent recruitment of diff...

In evaluation of the long-term success of a dental implant, the reliability and the stability of the implant-abutment interface plays a great role. Tapered interference fits provide a reliable connection method between the abutment and the implant. In this work, the mechanics of the tapered interference fits were analyzed using a closed-form formula and the finite element (FE) method. An analyt...

THE JOURNAL OF PROSTHETIC DENTISTRY 585 In the past 2 decades, finite element analysis (FEA) has become an increasingly useful tool for the prediction of the effects of stress on the implant and its surrounding bone. Vertical and transverse loads from mastication induce axial forces and bending moments and result in stress gradients in the implant as well as in the bone. A key factor for the su...

Dental implants have been used in replacing broken or damaged teeth. There are failures after the operation was done due to lack of primary stability. Through improving design dental implant, stability can be achieved. The aim study is analyse stress distribution at bone-implant interface different micro-thread designs. Five types two-dimension shapes implant embedded bone cube modeled ANSYS AP...

PURPOSE To establish a three-dimensional finite element model for orthodontic anchorage micro-implant,and to analyze the influence of different titled angles on the biomechanical characteristics of orthodontic anchorage implant-bone interface. METHODS ANSYS(Analysis System)finite element analysis software was used to perform the finite element modeling of the micro-implant with 7 different ti...

INTRODUCTION Long-term success of load-bearing implants require solid fixation of the implant to the host bone by the process of osseointegration. Osseointegration is achieved by the growth and mineralization of bone tissue onto and into the textured surface of implants. According to current theories on tissue differentiation, peri-implant tissue formation and subsequent mineralization are depe...

Achieving the stability of bone tissue in field dental implants is still most urgent and completely unsolved problem implantological practice. Modern ideas about biological principles structure functioning tissues periimplant zone are one significant factors ensuring crestal tissue. The soft-tissue component that forms basis complex at implant-suprastructure interface plays a key role protectin...
