Abstract

Implant dentistry constitutes a therapeutic modality in the prosthodontic treatment of partially and totally edentulous patients. This study reports a long-term evaluation of treatment by the early loading of acid-etched surface implants. Forty-eight partially and totally edentulous patients were treated with 169 TSA Defcon® acid-etched surface implants for prosthodontic rehabilitation. Implants were loaded after a healing free-loading period of 6–8 weeks in mandible and maxilla, respectively. Implant and prosthodontic clinical findings were followed during at least 17 years. Clinical results indicate a survival and success rate of implants of 92.9%, demonstrating that acid-etched surface achieves and maintains successful osseointegration. Five implants in three patients were lost during the healing period. Sixty-five prostheses were placed in 45 patients over the remaining 164 implants, 30 single crowns, 21 partially fixed bridges, 9 overdentures, and 5 full-arch fixed rehabilitations. A total of 12 implants were lost during the follow-up period. Mean marginal bone loss was 1.91 ± 1.24 mm, ranging from 1.1 to 3.6 mm. The most frequent complication was prosthetic technical complications (14.2%), followed by peri-implantitis (10.6%). The mean follow-up was of 214.4 months (208–228 months). Prosthodontic rehabilitation with an early-loading protocol over acid-etched surface implants is a successful implant treatment.

Highlights

Implant treatment of patients with partial or total tooth loss constitutes a well-documented surgical and prosthodontic therapy [1,2]
The present study included the clinical follow-up of 48 patients who received acid-etched surface implants in the School of Dentistry, University of Seville, with a follow-up period of 17 years
The long-term outcomes of this study indicate successful bone integration to the implants and agree with the reported results of other experimental and clinical studies with acid-etched surface implants [34,35,36,37]

Summary

Introduction

Implant treatment of patients with partial or total tooth loss constitutes a well-documented surgical and prosthodontic therapy [1,2]. The surface of dental implants plays an essential role in osseointegration. Osseointegration is related to the interaction between the implant surface and the hosts bone tissue [3]. The surface treatment might modify the roughness, the topography, and the surface chemical composition, and lead to different biological responses [4,5]. The surface treatment can increase the contact area between the implant and the hosting bone and improve both the cell migration and the attachment to the implant, enhancing the osseointegration process [6,7]. There is a need to modify the surface to improve the interaction with the extracellular environment and to enhance osteogenic responses as cell proliferation, adherence, and differentiation [6,7]
