Abstract

Objective To compare early implant failure and implant stability of one-stage Hiossen ET III implants with its new hydrophilic (NH) surface, compared with Hiossen ET III implants with the sandblasted and acid-etched (SA) surface at 1-year follow-up. Materials and Methods This study was designed as a split-mouth, multicenter randomized controlled trial aimed to compare SA surface implants (SA group) and NH surface, (NH group). Outcomes were implant and prosthetic survival rates, complications, the insertion torque at implant placement, and implant stability quotient (ISQ) values. Results Twenty-nine patients (mean age 59.9 ± 11.3 years) were treated and followed up to 1 year after loading. No patient dropped out. Fifty-eight implants (29 SA group and 29 NH group) were placed. No implants or prostheses failed and no complications were experienced during follow-up. The mean insertion torque was 40.5 ± 3.23 (38.17–41.83) Ncm in the SA group and 40.48 ± 3.49 (38.02–41.98) Ncm in the NH group ( p = 0.981). There was a statistically significant difference at the second week (T2) with higher values in the NH group ( p = 0.041). Similar results were found in the maxilla ( p = 0.045), but not in the mandible ( p = 0.362). A positive correlation was found between initial insertion torque and ISQ with higher value in the NH group (0.73 vs. 0.66). Conclusions NH implants are a viable alternative to SA surface, as they seem to avoid the ISQ drop during the bone remodeling phase.

Two weeks after implant placement, two Hiossen ET III SA implants showed a small mobility with an ISQ values lower than 55 (49 and 51, respectively)

Summary

Introduction

Modern dentist has an excellent solution to solve patient’s edentulism using dental implants. It has been shown that dental implants have long-term successful outcomes, representing a viable option for clinicians to rehabilitate complete or partial edentulous patients with both fixed and removable solutions.[1] Albrektsson et al introduced the concept of foreign body equilibrium, applied to the osseointegration of titanium dental implants. This equilibrium is an immune-mediated foreign body reaction balance during the biological integration of dental implants into the bone. Implant failures could still happen in a reduced number of compromised patients, due to the lack of enough understanding of related risk factors
