Background, training experiences, and career plans of U.S. periodontal residents: report of a web-based survey.

The purpose of this cross-sectional study was to survey the backgrounds and perspectives of U.S. periodontal residents in 2012.

Efficacy of growth factor in promoting early osseointegration.

A preclinical study was conducted to evaluate the feasibility of 2 different topical formulations of recombinant human platelet-derived growth factor-BB (rhPDGF-BB) to promote early osseointegration and enhanced bone-to-implant contact (BIC) for dental implants placed in an edentulous ridge. Six female beagle dogs were divided into 3 groups. The control group included 4 implants with no coating; test group A included 10 implants with commercially available rhPDGF-BB formulation coating; and second test group B included 10 implants with prototype viscous rhPDGF-BB coating.

The clinical and histologic outcome of dental implant in large ridge defect regenerated with alloplast: a randomized controlled preclinical trial.

A basic tenet of successful osseointegration is that the implant resides in a sufficient quality and quantity of bone to ensure bone contact and thus stabilization. A prospective, randomized controlled preclinical trial was conducted to evaluate the bone-to-implant contact (BIC) when placing implants in bone regenerated by 3 different combinations of biphasic calcium phosphate (BCP). Dental implants were placed into the regenerated ridges of 6 female foxhounds; the ridges were reconstructed with different formulations of BCP in combination with an hydroxyapatite collagen membrane.

Alveolar ridge reconstruction with a composite alloplastic biomaterial.

The purpose of this case report was to analyze the outcome of alveolar ridge reconstruction procedures with composite alloplastic biomaterial (biphasic calcium phosphate composed of 30% hydroxyapatite and 70% Β-tricalcium phosphate) for the treatment of large alveolar ridge defects. The clinical and histologic findings demonstrated that this alloplastic biomaterial can be used to potentially regenerate large alveolar ridge defects. This composite biomaterial appears to be safe, biocompatible, and osteoconductive.
