Dental prosthetic reconstruction of osseointegrated implants placed in irradiated bone.
Nineteen patients who were treated for oncologic pathology by surgery and radiotherapy (average dose = 57 Gy) received prosthetic reconstruction with 53 implants placed in the residual mandible or maxilla and/or replacement bone graft. Implants were placed within a minimum period of 5 months after radiotherapy. The healing period before placement of the prosthesis also was at least 5 months. Tw...

15 صفحه اولRevision medialization thyroplasty with hydroxylapatite implants.
INTRODUCTION Medialization thyroplasty is a useful tool in the management of dysphonia and dysphagia with aspiration secondary to unilateral vocal fold impairment. A variety of implant materials have been used for medialization thyroplasty including silicone elastomer (Silastic, Dow Corning Corporation, Midland, MI), expanded polytetrafluoroethylene (Gore-Tex, Gore, Newark, DE), and hydroxylapa...
متن کاملEffect of three different sanitizing solutions on the contaminated bone: an experimental study in the rabbit
Background: To determine the efficacy of three different antiseptic solutions (Control group (I), Antibiotic solution – Neomycin and polymyxin (II), Chlorhexidine 0.4% (III), and povidone – iodine 10% (IV)) in disinfecting contaminated bone fragments. Methods: Under sterile conditions, the femora of 12 rabbits were removed and cut into six millimeter pieces. A total of 200 bone specimens were ...
متن کاملA histomorphometric study of bone reactions to titanium implants in irradiated bone and the effect of hyperbaric oxygen treatment.
The present study was undertaken to histomorphometrically analyze early peri-implant bone tissue reactions that occur after radiotherapy and to determine whether hyperbaric oxygen therapy (HBO) affects bone tissue at the microscopic level by altering bone morphology. Twelve rabbits received a single dose (15 Gy) of cobalt60 radiation to one hind leg and the other hind leg served as a control. T...
