Freeze-dried bone allograft is an interesting treatment alternative to autogenous bone grafts. This clinical report presents a 3-year follow-up of an atrophic maxilla treated with freeze-dried bone allograft. Ridge augmentation was conducted with freeze-dried tibial allografts. Eight implants were used to support a full-arch prosthesis. Three years later, clinical and radiographic follow-up sho...

intraosseous ganglia can affect the carpal bones of the hand and must be considered in the differential diagnosis of wrist pain. a 38-year-old female presented with a 14-month history of left wrist pain and a radiolucent cystic lesion was seen computed tomography (ct) scanning. characteristic radiographic findings of a cyst in association with a fine sclerotic rim was apparent. we report an unu...

Minodronic acid hydrate was the first bisphosphonate developed and approved for osteoporosis treatment in Japan. With regard to inhibition of bone resorption, minodronic acid hydrate is 1000 times more effective than etidronic acid and 10-100 times more effective than alendronic acid. Clinical trials conducted to date have focused on postmenopausal female patients suffering from primary osteopo...

This study was conducted to evaluate the effects of a 3D-printed resorbable polycaprolactone/poly(lactic-co-glycolic acid)/β-tricalcium phosphate (PCL/PLGA/β-TCP) membrane on bone regeneration and osseointegration in areas surrounding implants and to compare results with those of a non-resorbable titanium mesh membrane. After preparation of PCL/PLGA/β-TCP membranes using extrusion-based 3D prin...

PURPOSE This study was conducted in order to investigate the therapeutic effect of closed reduction according to a classification in patients with nasal bone fracture. METHODS The study was conducted retrospectively on 186 patients with a mean age of 38 years (range: 7 to 80 years). All patients were diagnosed by clinical and radiologic examination, and then classified according to Hwang's cl...

This study was conducted to develop novel ceramic bone substitute that resembles the autologous bone behavior when used as graft material. Solid-state reaction at 1100°C was performed to synthesize β-tricalcium phosphate (β-TCP) and biphasic calcium phosphate (BCP). The ceramics were further analyzed to characterize phase composition, microstructural properties, cytocompatability and then chall...
