Outcome after placement of tantalum porous engineered dental implants in fresh extraction sockets: a canine study.
PURPOSE This study evaluated the stability and histologic proof of osseoincorporation of Trabecular Metal (TM) dental implants, which feature a tantalum-based porous midsection. MATERIALS AND METHODS A total of 48 TM implants (test group) and Tapered Screw-Vent implants (control group) were immediately placed bilaterally into mandibular extraction sockets in dogs. Resonance frequency analysis...
متن کاملThe application of porous tantalum cylinder to the repair of comminuted bone defects: a study of rabbit firearm injuries.
The aim of this study is to investigate the effect of porous tantalum material in repair tibial defects caused by firearm injuries in a rabbit model. A multifunctional biological impact machine was used to establish a rabbit tibial defect model of firearm injury. Porous tantalum rods were processed into a hollow cylinder. Kirschner wires were used for intramedullary fixation. We compared the di...
متن کاملCharacteristics of bone ingrowth and interface mechanics of a new porous tantalum biomaterial.
We have studied the characteristics of bone ingrowth of a new porous tantalum biomaterial in a simple transcortical canine model using cylindrical implants 5 x 10 mm in size. The material was 75% to 80% porous by volume and had a repeating arrangement of slender interconnecting struts which formed a regular array of dodecahedron-shaped pores. We performed histological studies on two types of ma...
متن کاملAdipose- Derived Stem Cells as a Tool for Dental Implant Osseointegration: an Experimental Study in the Dog
The biological interaction between the jaw bones and dental implant is fundamental for the long-term success of dental implant placement. Nevertheless, the insufficient bone volume remains a major clinical problem, especially in case of immediate dental implant. Using a canine model, the present study proves the regenerative potential of adipose- derived stem cells (ADSCs) to repair peri-implan...
متن کاملThe Effect of Trabecular Metal Porous Surface on Gap Healing and Bone Ingrowth Fixation in a Canine Total Hip Model
Introduction An exciting approach to reducing aseptic loosening of cementless implants is the stimulation and acceleration of bone ingrowth into the porous coatings of the implants. Improved fixation of components is an important factor for long term success of total hip and total knee replacement. While one method of stimulating bone formation utilizes biological agents such as BMP-2 or OP-1. ...
