Repositioning Implants Through Sandwich Osteotomy with the Interposition of Lyophilized Bovine Bone

Abstract

The satisfactory positioning of an implant during dental surgery is essential to the success of the treatment. However, accidents can occur during the period of osseointegration, leading to implant movements that hinder or may even prevent prosthetic rehabilitation. Implants can be repositioned through sandwich osteotomy, which has been labeled a versatile, viable and predictable technique in the literature. The aim of the present study was to report a case involving the esthetic displacement of an implant, caused by a sports accident, which was repositioned using sandwich osteotomy, with the interposition of lyophilized bovine bone between the osteotomized segments. In order to adequately perform this repositioning, the authors devised a guide to assist with the positioning process.

Polylactic Acid Printed Scaffold on Collagen Membrane: Physical, Chemical Analysis and the Report of 2 Clinical Cases

“…Extensive clinical-surgical cases of dental bone regeneration and correction utilizing the LUMINA COAT barrier, involve techniques in sinus trans fixation [3], severe alveolar resorption by occlusal trauma [4], vertical treatment of the alveolar ridge [5], repositioning of grafted implants [6], horizontal technique of bone thickness increase [7], parendodontic surgery [8], remotion of migrated implant on the maxillary sinus [9], anti-microbial therapy for bone regeneration [10], etc. The polylactic acid (PLA, PDLA, PLLA or PDLA/PLLA) is being well known as a biocompatible and resorbable polymer of elevated perspective to compose surgical devices aimed at tissue regeneration [11,12].…”
