Histological observations on the healing of a periodontal defect five years after an autogenous bone graft.
A bone autograft obtained from the iliac crest was implanted into the periodontal region of the lower first molar (36) in a patient suffering from juvenile periodontitis. In the present paper we describe the results of a biopsy obtained 5 years after the graft implantation. The radiological, histological and ultrastructural images obtained suggested that neoformation of bone, cementum-like tiss...
متن کاملScanning electron and light microscopic observations on the healing process after sintered bone implantation in rats.
The healing process after implantation of sintered bone in the rat parietal bone was compared with that of synthetic hydroxyapatite using both scanning electron and light microscopy. The results showed that the differences between the sintered natural bone and the synthetic hydroxyapatite implantations were in the states of bone union and the bioresorbability of the implanted materials, even th...
متن کاملclinical and radiographic methods of marginal bone loss evaluation after immediate implantation in post-extraction sockets.
Introduction: To achieve the best esthetic and functional results of implantation and patient satisfaction, different protocols of implant therapy have been recommended. Immediate implantation can provide the outcome faster than other protocols making it the treatment of choice. The rate of peri-implant bone resorption should be measured clinically and radiographically as bone support is a key ...
متن کاملBone Regeneration and Remodeling within a Unidirectional Porous Hydroxyapatite Bone Substitute at a Cortical Bone Defect Site: Histological Analysis at One and Two Years after Implantation
Unidirectional porous hydroxyapatite (UDPHAp) is an artificial bone substitute with a unique microstructure consisting of 100-300-µm oval pores that present the material unidirectionally. UDPHAp has a compression strength of 14 MPa and a porosity of 75%, which promotes cell migration and capillary formation within the material. Despite these advantageous properties, bone remodeling and bone for...
متن کاملCochlear Implantation after Bilateral Transverse Temporal Bone Fractures
Patients deafened by a severe head injury are rarely encountered. We report a case of a 65-yr-old man with bilateral transverse temporal bone fractures due to head injury. He underwent cochlear implant and achieved a satisfactory auditory rehabilitation. Imaging studies of temporal bone before performing a cochlear implantation provide important information on a patient with bilateral temporal ...
