Replacement of the lumbar vertebrae of sheep with ceramic prostheses.
We prepared a prosthesis for the replacement of the lumbar vertebrae of sheep, using apatite- and wollastonite-containing glass-ceramic. The material is stronger than human cortical bone and has the special feature of chemical bonding to bone. Ten sheep underwent replacement of L3 and L4 vertebrae, without bone grafting. The animals were killed at intervals from three months to 27 months after ...
متن کاملOutcome of bonded vs all-ceramic and metal- ceramic fixed prostheses for single tooth replacement.
AIM The conventional treatment of a single missing tooth is most frequently based on the provision of a fixed dental prosthesis (FDPs). A variety of designs and restorative materials are available which have an impact on the treatment outcome. Consequently, it was the aim of this review to compare resin-bonded, all-ceramic and metal-ceramic FDPs based on existing evidence. MATERIALS AND METHO...
متن کاملBioactive Ceramic-polymer Composites for Tissue Replacement
Bone, at the ultra-structural level, is a composite with mechanical properties that can be matched by man-made composites. It serves as the template for developing bone replacement materials. Research on biomaterials analogous to bone was started in the early 1980s by incorporating bioactive particles into biocompatible polymers in order to produce bone substitutes. Hydroxyapatite reinforced hi...
متن کاملNormal and pathologic tissue reactions to soft tissue gel fillers.
BACKGROUND All gels act as foreign bodies. Host response ranges from a few macrophages to an intense foreign-body reaction with fibrosis, depending on gel type. For polymer gels the filling effect stems from their volume. For combination gels it stems from the intended host foreign-body reaction to the microparticles. OBJECTIVE This review explains how host tissue reacts with different gel ty...
متن کاملFabricating auricular prostheses using three-dimensional soft tissue models.
This article describes a method for fabricating an auricular prosthesis. This procedure uses the contours of the soft tissue surface from computerized tomography scans to fabricate a computer-generated, side-inverted 3-dimensional soft tissue model from a solid block of polyurethane using an Endoplan milling machine. The resultant 3-dimensional soft tissue model can then be used as the basis fo...
