성견에서 발치후 즉시 식립후 즉시 부하된 RBM, CMP 임플란트의 조직형태계측학적 평가

Abstract

Purpose: This study is a histometric analysis of immediate implantation and immediate loading of chemical mechanical polishing (CMP) and resorbable blast media (RBM) surface implants. Material and Methods: The first through fourth mandibular premolars were extracted from five adult dogs. Immediate implantation was performed in the fresh extraction socket. The dogs received two implants each with CMP and RBM surfaces. The first premolar was submerged, and 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, and the animals were sacrificed and processed histologically to obtain non-decalcified sections. Longitudinal ground sections were made for each implant, and the histometry was analyzed under light microscopy. Result: No statistically significance difference was found between the control group and the experimental groups based on immediate loading (p > 0.05) and implant surface (p > 0.05), but there was a significance difference between the vertical defect side and the non-defect side of the implant surface in the extraction socket (p < 0.05). Conclusion: The implant success rate and implant-to-bone contact rate after immediate loading were similar to those of submerged implants. CMP and RBM surface implants did not differ in terms of the implant success rate or implant-to-bone contact rate.
