BACKGROUND Premature membrane exposure for guided bone regeneration may result in complications, such as inadequate bone regeneration, inflammatory reactions, and wound infection. This paper presents a clinical case of a novel incision-flap design used to advance the flap to enhance tension-free primary closure for the vertical ridge augmentation. METHODS(More)
PURPOSE The aim of this study was to evaluate the efficacy and morbidity of two periodontal releasing incision techniques in vertical ridge augmentation. MATERIALS AND METHODS Twenty-three vertical and horizontal defects (Seibert Class III) were selected to compare the double-flap incision (DFI) to the conventional periosteal releasing incision (PRI). An(More)
Fertilization failures have occurred repeatedly in reproductive centers after intracytoplasmic sperm injection (ICSI) and artificial oocyte activation (AOA) has been used to prevent it. This study was performed to investigate whether spermatozoan origin influences clinical outcomes of AOA with a calcium ionophore. A total of 185 ICSI cycles with a history(More)
BACKGROUND In this study, an association between a computerized risk calculator and microbiologic testing is examined in patients with periodontitis. METHODS Seventy-four patients with moderate and severe periodontitis were selected from patients receiving treatment at Tufts University School of Dental Medicine. Their periodontal risk was analyzed with a(More)
Three patients with multiple Miller Class III recession defects with substantial bone loss were treated with hard tissue augmentation with the goal to prevent future recessions. The surgery involved a full-thickness mucoperiosteal coronally advanced flap, bone grafting, and primary flap closure. Freeze-dried bone allograft (FDBA) in combination with plasma(More)
BACKGROUND There is limited evidence on the crestal bone level changes around implants placed in bone augmented by guided bone regeneration (GBR) during submerged healing. The purpose of this study was to prospectively compare radiographic crestal bone changes around implants placed in augmented bone with changes around implants placed in pristine bone. (More)
