A histologic evaluation of localized ridge augmentation utilizing DFDBA in combination with e-PTFE membranes and stainless steel bone pins in humans.
This study evaluated histologically and clinically the use of decalcified freeze-dried bone allograft in conjunction with Gore-Tex Augmentation Material and Memfix bone pins for localized ridge augmentation in three cases. Biopsies taken at 3, 6, and 9 months were evaluated. It was concluded that: (1) guided bone regeneration may be performed at local immediate extraction sites when flap design permits primary wound closure; (2) decalcified freeze-dried bone allografts used in conjunction with supporting pins may contribute to successful bone regeneration either by osseoinduction or osseoconduction, and/or by maintaining the membrane-created space during the early events in wound healing; and (3) at 9 months, guided bone regeneration utilizing Gore-Tex Augmentation Material membranes and decalcified freeze-dried bone allografts resulted in the formation of dense, viable new bone.
