Titanium barriers have been used for guided bone regeneration in preclinical and preliminary clinical reports as a possible alternative to bone grafting. In two cases with lateral bone defects, rigid titanium barriers were used to provide a secluded space in conjunction with bone substitutes. Sufficient lateral bone volume was generated for implant placement, and no complications were observed ...

BACKGROUND Recombinant human bone morphogenic protein-2 stimulates bone augmentation in animal models. The aim of this study was to evaluate the capacity of bovine bone mineral coated with synthetic oligopeptides to enhance guided bone regeneration in the beagle 3-wall defect model and the clinical implications. METHODS The second and fourth mandibular premolars of four adult beagle dogs were...

the purpose of this study was to evaluate the efficacy of two types of bone substitutes, bio-oss and nuoss, for repair of bone defects.this study was performed on the calvaria of 14 new zealand rabbits. the 6mm critical size defect (csd) models of bone regeneration were used. three csds were created in each surgical site. the first defect was filled with nuoss, the second one with bio-oss and t...

Conflicting data exist on the combined use of grafting materials and barrier membranes in comparison to guided tissue regeneration (GTR) with membrane alone. The aim of the present study was to compare the clinical outcomes of GTR with collagen membrane (CM) alone (control group) or CM combined with autogenous bone graft (test group 1) or autogenous bone mixed with bioactive glass (test group 2...

objective: the aim of present study was to evaluate the quality, density and thickness of newly formed bone in experimental defects treated with combi-pack®, bio-oss® and biostite®. materials and methods: eight new zealand white rabbits were included in this randomized,blinded study. four equal 3×6 mm bone defects were created on the frontal and parietal bones of each animal and three were imme...

Installation of dental implants is often hindered by compromised alveolar ridge which requires augmentation. Several methods including autogenous bone graft, guided bone regeneration, and distraction osteogenesis are implied to restore the compromised alveolar ridge. This chapter reviews treatment modalities and techniques of alveolar ridge augmentation. Recent development and updates in this f...

t implant bone reconstruction using allogenic bone grafts is a technique based on, not only the bone regeneration advantages, but also those of the tissue increase to correct the bone volume lacks in the peri-implant areas. This is about an increase in width of the alveolar crest by adjunctions of allogenic bone grafts which are first adapted to the local tissues and then stabilized with micros...

BACKGROUND Implant surgery has become popular with the advance of surgical techniques such as sinus lifting, guided bone regeneration, and block bone graft. However, there were no data about the frequency of bone graft during implant surgery. The purpose of this study was to report the frequency and types of bone graft depending on dental implant patients' profile to complement the database reg...
