Effect of Loading Protocol on Peri-Implant Marginal Bone Loss (Clinical Trial)

Abstract

This randomized controlled clinical trial aimed at evaluating immediate functional loading versus immediate non – functional loading of dental implants with a new permanent hybrid ceramic crown material. The purpose of this clinical trial was to evaluate the efficacy of the hybrid ceramic material in permitting osseointegration while benefiting from its properties as a permanent restoration such as fracture resistance, polishibility, stain resistance, and marginal integrity. Cone Beam Computed Tomography was used for assessment of buccal, palatal, mesial, and distal marginal bone loss throughout the one year follow – up period. Group I showed a statistically non significant higher amount of bone loss than group II after 3, 6, and 12 months follow – up. Group II showed a statistically significant higher amount of bone loss than gp III at 3, 6 and 12 months follow up. .All the three groups showed a statistically significant amount of bone loss after 12 months when compared to the baseline. Previous literature established the acceptable amount of bone loss to be between 1 – 2 mm. The results of this study were within the acceptable limits of previous literature. This study showed that a new hybrid ceramic material has the potiental to be used in conjunction with immediate implant loading functionally and non – functionally as a replacement for traditional temporary crown materials, while benefiting from its mechanical and physical properties as a permanent restoration.
