[Hydroxyapatite implant for human periodontal osseous defects].
The purpose of this study was to evaluate the efficacy of porous hydroxyapatite (HAP) as an implant material into human periodontal defects. Thirty three patients affected by marginal periodontitis were studied. Following initial therapy, 44 periodontal osseous defects received grafts of HAP granules and blocks during flap surgery. Radiographic and various clinical examinations were performed b...
متن کاملOsseous Defects Seen in Patients with Anterior Shoulder Instability

متن کاملOsseous Reconstruction of Complex Defects of the Lumbar Spine
1 Sir: C defects of the lumbar spine present significant challenges for the reconstructive surgeon due to the lack of local reconstructive options, the need for immediate postoperative rigidity, and long-term resistance to axial compression forces. With recent studies showing significant improvements in quality of life from operative management of neoplastic disease of the spine, this rare clin...
متن کاملReconstruction of Peri-implant Osseous Defects: A Multicenter Randomized Trial.
There is a paucity of data for the effectiveness of reconstructive procedures in the treatment of peri-implantitis. The objective of this study was to compare reconstruction of peri-implant osseous defects with open flap debridement (OFD) plus porous titanium granules (PTGs) compared with OFD alone. Sixty-three patients (36 female, 27 male; mean age 58.4 y [SD 12.3]), contributing one circumfer...
