background and aim: although there have been substantial developments in dental implant therapies, achieving good implant stability (isq >60) for implants inserted in augmented sinus sites appears to be challenging in comparison with non-augmented sites due to the high prevalence of bone resorption in posterior regions of maxilla. this study aimed to evaluate and compare the time required to a...

BACKGROUND Purified recombinant human platelet-derived growth factor BB (rhPDGF-BB) is a potent wound healing growth factor and stimulator of the proliferation and recruitment of both periodontal ligament (PDL) and bone cells. The hypothesis tested in this study was that application of rhPDGF-BB incorporated in bone allograft would induce regeneration of a complete new attachment apparatus, inc...
Various materials are used in modern dental and maxillofacial surgery for bone tissue substitution and reconstruction. All osteoplastic materials can be divided into four groups by origin: autogenic, allogenic, xenogenic and synthetic. Synthetic resorbable materials were intended as an inexpensive substitute for natural bone. Synthetic graft materials include various types of ceramics: tricalci...
همان طور که می دانیم همواره ریسک از دست رفتن دندان های مولر دچار درگیری فورکیشن در مقایسه با دندان های مولر فاقد درگیری فورکیشن حین فاز نگهدارنده درمان پریودنتال وجود دارد. روشهای مختلفی از جمله open flap debridement، gtr و کاربرد مواد گرفتی استخوان با موفقیت در درمان ضایعات فورکیشن به کار رفته اند که عموماً با مقادیر متفاوتی از بهبود چسبندگی کلینیکی و کاهش عمق پاکت همراه بوده اند. اما هر مطالع...
