Histometric Analysis of Immediate Implantation and Immediate Loading of CMP and RBM Implants after Tooth Extraction in Dogs

Abstract

This study analyzed immediate implantation and immediate loading of chemical mechanical polished (CMP) and resorbable blast media (RBM) SSIII OSSTEM dental implants histometrically. The 1st, 2nd, 3rd, and 4th mandibular premolars were extracted from five adult dogs. Immediate implantation was performed in the fresh extraction sockets. Each dog received two types of implant: CMP and RBM. The first premolar was submerged, whereas the second, third, and fourth were not submerged. The implants were splinted using acrylic resin and subjected to immediate loading. After 4 months, X-rays were taken and analyzed. The animals were euthanized and processed histologically to obtain non-decalcified sections. Longitudinal ground sections of each implant were made, and histometry was analyzed under light microscopy. No significant difference was found between the control and experimental groups based on immediate loading (p > 0.05) and implant surface (p > 0.05). The implant survival rate and implant-to-bone contact rate after immediate loading were similar to those of submerged implants. The CMP and RBM dental implants did not differ in terms of implant survival rate and implant-to-bone contact rate.
