Osteogenic protein 1 device increases bone formation and bone graft resorption around cementless implants.
In each femoral condyle of 8 Labrador dogs, a non weight-bearing hydroxyapatite-coated implant was inserted surrounded by a 3 mm gap. Each gap was filled with bone allograft or ProOsteon with or without OP-1 delivered in a bovine collagen type I carrier (OP-1 device). 300 microg OP-1 was used in the 0.75 cc gap surrounding the implant. After 3 weeks, the OP-1 device enhanced implant fixation by...
متن کاملComparison of autogenous tooth bone graft and synthetic bone graft materials used for bone resorption around implants after crestal approach sinus lifting: a retrospective study
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...
متن کاملBuccal bone resorption around posterior implants after surgery: a 1-year prospective study.
PURPOSE This prospective study aimed to examine postoperative dimensional changes in the buccal bone and mucosa around single-stage implants placed in the posterior region. MATERIALS AND METHODS The dimensions of peri-implant tissue around screw-type implants placed in the posterior region were examined at surgery (baseline) and 6 months and 1 year after surgery. The lateral contour of the bu...
متن کاملBone remodelling around a cementless glenoid component.
Post-operative change in the mechanical loading of bone may trigger its (mechanically induced) adaptation and hamper the mechanical stability of prostheses. This is especially important in cementless components, where the final fixation is achieved by the bone itself. The aim of this study is, first, to gain insight into the bone remodelling process around a cementless glenoid component, and se...
متن کامل0618 - Osteogenic Protein 1 (op-1) Increases Bone Graft Incorporation Which Is Delayed by Morselization and Impaction
Introduction The use of morselized impacted cancellous allografts for hip arthroplasty revision surgery shows results which seem to differ dramatically from other kinds of allografting (1,2). In structural cancellous allografts, bone ingrowth is usually limited to 2-3 mm (3), whereas the whole of morselized impacted grafts seem to be remodelled in several cases as judged by radiography (1,4). I...
