Bone formation in rejected corneal graft.

Histopothology of Rejected Orthotopic Corneal Grafts in the Rat

We have used an orthotopic graft model in the rat to study the histologic characteristics of corneal allograft rejection. Unrejected allogeneic grafts could not be distinguished from clear syngeneic grafts. Although donor Langerhans cells are necessary for the development of delayed-type hypersensitivity (DTH), the histopathological characteristics of rejecting corneal allografts in immunologic...

CLINICAL EVALUATION OF BONE CEMENT AND AUTOGENOUS BONE GRAFT IN DOGS

Various biological bone g rafts have been used for osteogenes i s , osteoconduction and even osteoinduction, but due to systemic influences and local factors, the outcome of successful incorporation of a bone graft has not been satisfactory. This study was therefore conducted on 15 clinically healthy adult dogs between 1 to 3 years of age weighing 20 to 30 kg to evaluate the effect of bo...

New Bone Formation in the Maxillary Sinus With/Without Bone Graft

Pneumatization of maxillary sinus causes insufficient vertical bone volume on posterior maxilla. So the restoration of edentulous posterior maxilla with dental implants is challenging due to a deficient posterior alveolar ridge, unfavorable bone quality and increased pneumatization of the maxillary sinus.1 For maxillary sinus augmentation, the crestal approach and the lateral window approach ha...

Bone Formation in Maxillary Sinus Lift Using Autogenous Bone Graft at 2 and 6 Months.

The aim of this study is to compare the bone formation in maxillary sinus lift with an autogenous bone graft in histological evaluation at 2 or 6 months. A comparative study was designed where 10 patients with missing teeth bilaterally in the posterior zone of the maxilla were selected. Patients received a particulate autogenous bone graft under the same surgical conditions, selecting a site to...
