Extensor sobre implante dental osseointegrado com regeneração óssea guiada: Relato de caso

Abstract

Background: The extension implant is unprecedented in the world, originally used in experiments involving animals, and now through this case study, has been used in conjunction with Guided Bone Regeneration in Participants. Objective: This case study aims at extending the length of the osseointegrated implant associated with Guided bone Regeneration for reestablishing biological distance and reducing the length of the prosthetic crown. Materials and Methods: An implant extender was installed in the osseointegrated dental implant with particulate autogenous bone from the Maxilla tuft and resorbable collagen membrane. After 6 months of repair, the mobility of the extender was evaluated and the porcelain prosthetic crown installed onto the extender/implant assembly. Measurements were performed before and after the extender/prosthesis installation, as well as the Radiographic Tomography for assessing the bone neoformation of the implant extender along with the adaptation of the extender-implant prosthesis assembly. Results: The extender/implant assembly did not present mobility in the clinical assessment. The radiographic tomography presented bone neoformation in the vestibular region, around the extender, according to the assessment of the researcher a prosthodontist that has experience in this particular area. The probing depth decreased after placement of the Dental Implant Extender, thus modifying the biological space Discussion and Conclusion: The osseointegration, short implants and bone reconstruction techniques have already been validated, thus making the study of implant extenders viable. The process is reversible, which allows for the application of bone reconstruction techniques without the removal of the implant, while taking the position of reducing the risk of losing the new implant, risk of greater bone loss, thus making the idea of continuing new cases an interesting prospect. In addition, in this case report, the conclusion was reached that the reestablishment of the biological space was achieved, along with the absence of mobility of the prosthesis on the extender/implant for more than 2 years.
