mandibular defects may result from many conditions such as trauma, inflammatory diseases and tumors. there are rare cases reported in the literature that have demonstrated spontaneous bone regeneration after resection of the mandible. several factors such as age, preservation of the periosteum and genetics seem to influence spontaneous bone regeneration capacity in individuals. evaluation of th...

Nowadays, dental implants represent a reliable and successful procedure for the prosthetic restoration of partially and totally edentulous patients, with high survival and success rates in the short, medium, and long term. However, a sufficient amount of bone—in terms of height and width of the residual bone crest—is needed to place dental implants in the proper position and inclination, to all...

The aim of this investigation was to evaluate the osteoinductive property of autogenous demineralized dentin matrix (ADDM) on experimental surgical bone defects in the parietal bone of rabbits using the guided bone regeneration (GBR) technique incorporating human amniotic membrane (HAM). Thirty-six rabbits were divided into 2 groups, HAM and ADDM+HAM. It was possible to conclude that HAM did no...

OBJECTIVES Analyse the effectiveness of different materials and techniques used in guided tissue regeneration (GTR) applied in periapical surgery, comparing the success rate obtained in 4-wall defects and in through-and-through bone lesions as well as to establish prognostic factors. MATERIAL AND METHODS A Cochrane, PubMed-MEDLINE and Scopus database search (October 2012 to March 2013) was co...

Guided bone regeneration is a unique osteogenesis technique that requires a barrier membrane under periosteum to create space for bone regeneration. However, creating sizeable spaces is clinically not commonly feasible. A titanium plate and a thin silicone membrane were surgically layered on each calvaria of eight rabbits. Then, the periphery of the silicone membrane was fixed by a plastic ring...

The purpose of this study is to evaluate the effect of three-dimensional preformed titanium membrane (3D-PFTM) to enhance mechanical properties and ability of bone regeneration on the peri-implant bone defect. 3D-PFTMs by new mechanically compressive molding technology and manually shaped- (MS-) PFTMs by hand manipulation were applied in artificial peri-implant bone defect model for static comp...
