PURPOSE To evaluate the efficacy of porous expanded polytetrafluoroethylene (e-PTFE, Goretex) containing large pores made with a 21-gauge needle as a graft for the correction of lower lid retraction. METHODS e-PTFE grafts were implanted between the tarsus and lower lid retractor via a transconjunctival approach with/without amniotic membrane transplantation, or via a transcutaneous approach. ...

OBJECTIVE The objective of this study was to histologically and histomorphometrically evaluate the efficacy of the new formulations of eggshell-derived calcium carbonate in rats. STUDY DESIGN The study was conducted on 30 adult male rats. Four standardized and circular intrabony defects were created in the both maxilla and mandibula of each animal. Three different graft materials were prepare...

MATERIALS AND METHODS: We report on our treatment of 6 limbs in 3 patients (age range, 19–36 years). In each case we applied fat graft at the medial side of the limb 150–175 cc. There were minimal deformity (Langenskiöld stage 1), patients had only aesthetic complaint, not pain or osteoartrit.The varus angulation at the tibia was measured and osteoarthritis was evaluated with radiographs.Patien...

Bone grafting is utilized in nearly all orthopedic subspecialties and in most anatomic regions. Bone graft substitutes have the potential to offer similar efficacy as autogenous grafts without the morbidity of harvest. Several studies have noted the efficacy of new-generation bone substitute products, but few studies have evaluated their safety. This study characterizes and quantifies the infla...

PURPOSE This retrospective study compares the amount of bone resorption around implants between an autogenous tooth bone graft (AutoBT) and a synthetic bone graft after a bone-added crestally approached sinus lift with simultaneous implant placements. METHODS In all, 37 patients participated in this study. Seventeen patients were grouped as group I and underwent an AutoBT-added sinus lift usi...

BACKGROUND Increasing sinus pneumatization and the accompanying alveolar bone resorption complicate dental implant placement. This problem can be overcome today by raising the maxillary sinus floor with graft materials. Bisphosphonates are commonly used to accelerate the recovery of the graft materials and to prevent resorption. OBJECTIVES The purpose of this study is to investigate whether s...

A majority of patients with orofacial cleft deformity requires cleft repair through a bone graft. However, elevated amount of bone resorption and subsequent bone graft failure remains a significant clinical challenge. Bisphosphonates (BPs), a class of anti-resorptive drugs, may offer great promise in enhancing the clinical success of bone grafting. In this study, we compared the effects of syst...
