Avaliação da estabilidade primária em implantes com diferentes tratamentos de superfície por meio da análise de frequência de ressonância

Abstract

The prerequisites for success in Implantology, in addition to osseointegration, are obtaining and maintaining implant stability. Much research has been done regarding the surface treatment of implants in order to enhance and shorten the osseointegration time. This gave rise to the concept of hydrophilicity, which influences the level of contact between a biomaterial and the cells present in the tissue where it is inserted. The aim of this study was to evaluate the stability coefficient (ISQ) of two different surfaces of dental implants, one hydrophobic (Neoporos) and the other hydrophilic (Acqua), through the method of resonance frequency analysis (AFR) using Osstell (Integrations Diagnostics, Gothenburg, Sweden). Four implants (3.75 x 9.0 mm, hybrid design with cylindrical body and conical apex and morse taper connection) were inserted in the posterior region of the maxilla with two different surface treatments, one of which was treated with acid etching and blasting (hydrophobic surface – Neoporos - Neodent, Curitiba, Brazil) and another treated similarly to the previous one, but stored in sodium chloride for protection (hydrophilic surface - Acqua - Neodent, Curitiba, Brazil). ISQ measurements (performed in the mesial, buccal, distal, occlusal, and palatal of the implants) were performed in the postoperative T0 (0 days), T1 (40 days), and T2 (90 days). The results allowed us to conclude that, in the present study, there were no significant differences between the means of ISQ of implants with a hydrophilic surface versus implants with a hydrophobic surface, through the AFR.
