Introduction: Implant restorations should endure a variable range of forces over long period time. Some commercial brands offer the implant together with an accessory called “implant mount” or holder,” which might be used as temporary abutment. However, scientific literature in use holders abutments for is scarce.Objectives: The purpose this vitro study was to compare load at Direct® and Zimmer...

The rehabilitation of patients with dental implant-supported restorations is an ideal treatment option in contemporary dentistry. aim this review was to compile and demonstrate the mechanical response during loading condition, on stress distributions prostheses. findings show that majority stresses were concentrated cervical region implant/abutment interface may can be affected by several clini...

In ten male rats we inserted ceramic 'drawing-pin' implants in weight-bearing positions within the right proximal tibia. Two animals were killed 6 weeks after surgery and two more 14 weeks after surgery. The remaining six received intra-articular injections of either high-density polyethylene (4 rats) or saline (2 rats) at 8, 10 and 12 weeks after surgery. These animals were killed two weeks af...

PURPOSE The aim of this investigation was to measure the temperature increase due to heat transferred to the implant-bone interface when the abutment screw channel is accessed or a metal-ceramic crown is sectioned buccally with diamond or tungsten carbide bur using an air rotor, with or without irrigation. MATERIALS AND METHODS Cobalt-chromium copings were cemented onto straight titanium abut...

Introduction The development and evaluation of orthopaedic devices are commonly assisted by finite element analysis [1]. Computational models are usually simplified through approximations to enable efficient simulations, without affecting the outcome of relative comparisons between different implant designs or configurations. The physical behavior of the bonescrew interface prior to osseointegr...

This in vitro study quantified the marginal discrepancy of the implant-to-prosthetic-crown interface on nonsubmerged dental implants restored with either a cemented or a screw-retained approach. Metal-ceramic crowns were fabricated for 20 ITI 4.1 x 10 mm solid-screw titanium implants. Ten implants received octa abutments and screw-retained crowns fabricated on premachined gold cylinders. The re...

BACKGROUND The biologic width around implants has been well documented in the literature. Once an implant is uncovered, vertical bone loss of 1.5 to 2 mm is evidenced apical to the newly established implant-abutment interface. The purpose of this study was to evaluate the lateral dimension of the bone loss at the implant-abutment interface and to determine if this lateral dimension has an effec...

Many investigators consider the polymethylmethacrylate-bone interface the weakest link in the bone-cement-implant system. Push-out tests, frequently used for in vitro evaluation of the bone-cement interface, produced inconsistent results of shear strength. Therefore, a more reliable model for testing the shear failure of the interface was developed. Better understanding of intrinsic variations ...

OBJECTIVE To assess if the bonding interlayer between the implant and bone in aseptic loosening of total hip replacement (THR) is qualitatively deteriorated by excessive accumulation of anti-adhesive glycoprotein, tenascin-C. METHODS Alkaline phosphatase-anti-alkaline phosphatase (APAAP) method was used for immunohistochemical staining of tenascin-C in interface tissue and control synovial ti...

This review makes an attempt to give comprehensive description of osseointegration, its history, bone to implant interface, cellular background and the factors involved in the phenomenon termed osseointegration.
