One-Piece Implant-Retained Mandibular Overdentures By Prefabricated Titanium Telescopic Attachments and FrictionaI Varnish: A Two-Year Prospective Study

摘要

Clinicsl efficiency of one-piece screw-type implants with telescopic were attachments evaluated in this study. Twenty-four patients received a mandihular implant-supported overdenture and maxillary complete denture. Ninety-six one-piece implants were inserted in the inter-foraminal area. Implants were immediately loaded with an implant-retained overdenture and telescopic attachments which had ffictional retention elements. There was 0.25±0.24 mm, 0.32±0.25 mm, 0.43±0.30 mm, 0.61±0.30 mm and of bone resorption after 3,6,12 and 24 months, respectively. The need to activate the I'fictional retention was the most common complication. Treatment outcomes for prefabricated telescopic retained overdentures on one-piece implants are similar to that obtained in cases of delayed loading.
