Evaluation of bone ingrowth into porous titanium implant: histomorphometric analysis in rabbits.
A porous material for bone ingrowth with adequate pore structure and appropriate mechanical properties has long been sought as the ideal bone-implant interface. This study aimed to assess in vivo the influence of three types of porous titanium implant on the new bone ingrowth. The implants were produced by means of a powder metallurgy technique with different porosities and pore sizes: Group 1 ...

15 صفحه اولEvaluation of different rotary devices on bone repair in rabbits.
In oral surgery, the quality of bone repair may be influenced by several factors that can increase the morbidity of the procedure. The type of equipment used for ostectomy can directly affect bone healing. The aim of this study was to evaluate bone repair of mandible bone defects prepared in rabbits using three different rotary devices. Fifteen New Zealand rabbits were randomly assigned to 3 gr...
متن کاملHistologic and histomorphometric analysis of the bone response to machined and sandblasted titanium implants: an experimental study in rabbits.
The aim of this study was to make a comparative analysis between the bone response to machined and sandblasted implants. The sandblasting was done with 150-microns aluminum oxide particles. Under scanning electron microscopic examination, the machined implants presented typical machining grooves, while a very rough, highly irregular surface with depressions and indentations was present on the s...
متن کاملEvaluation of the Repair of Bone Defect after Bone Marrow Stromal Cell Transplantation in Rat
Background & Objective: Bone marrow stromal cells (BMSCs) are multipotent stem cells that can proliferate and differentiate into osteogenic cells . T his study aimed to investigate the effects of BMSC transplantation for the repair of bone defects in the rat. Materials & Methods : Twenty-eight male adult rats were divided into 4 groups. Group 1 ( control group) received no treatment after the...
