Removal torque values of titanium implants in the maxilla of miniature pigs.
The purpose of this study was to compare side-by-side two different titanium screw-type implants in the maxillae of miniature pigs. The test implants had a machined and acid-etched surface (Osseotite) whereas the control implants were sandblasted and acid-etched (SLA). After 4, 8, and 12 weeks of healing, removal torque testing was performed to evaluate the shear strength of the bone-implant in...
متن کاملHistologic evaluation and removal torque analysis of nano- and microtreated titanium implants in the dogs
STATEMENT OF PROBLEM A number of studies about the nano-treated surfaces of implants have been conducting along with micro-treated surfaces of implants. PURPOSE The purpose of this study was to get information for the clinical use of nano-treated surfaces compared with micro-treated surfaces by measuring removal torque and analyzing histological characteristics after the placement of various ...
متن کاملBiomechanical evaluation of dental implants with different surfaces: Removal torque and resonance frequency analysis in rabbits
STATEMENT OF PROBLEM Macroscopic and especially microscopic properties of implant surfaces play a major role in the osseous healing of dental implants. Dental implants with modified surfaces have shown stronger osseointegration than implants which are only turned (machined). Advanced surface modification techniques such as anodic oxidation and Ca-P application have been developed to achieve fas...
متن کاملRemoval torque of osseointegrated mini-implants: an in vivo evaluation.
The possibility of using osseointegrated implants for orthodontic anchorage is well known. When absolute orthodontic anchorage is needed, mini-implants can be inserted in the non-alveolar bone area (e.g. palatal process or retromolar areas of the mandible). However, what happens to these implants at the end of treatment can be a problem as neither trephine explantation nor simply leaving the su...
متن کاملTorque removal force for osseointegrated implants--two experimental studies.
OBJECTIVE To introduce a rabbit-based model for testing the torque removal force (TRF) of implants and to compare the TRF of a series of titanium implants. METHODS Two experiments were performed at the University of the Witwatersrand. In the first, a Swedish- (SSM-N) or a South African-manufactured (SSM-S) implant was implanted into the tibiae of 12 rabbits and the TRF measured at 1, 3 and 6 ...
