Clinical Evaluation of Bucco-lingual Crestal Bone Remodeling in Mandibular Posterior Implants placed immediately and...

The objective of this cross sectional study was to evaluate the bucco-lingual crestal bone remodeling in mandibular posterior implants placed immediately and delayed into extraction sites and carried out in the department of Prosthodontics of Dhaka Dental College and Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from July 2010 to July 2014. Forty patients were evaluated in this study; of them 25(62.5%) patients were males and 15(37.5%) were females with age range from 24 to 70 years. At first surgery during implant placement the mean distance from buccal bone to lingual bone was 11.11mm for immediate implants and 9.265mm for delayed implants. At second-stage surgery the mean distance from buccal bone to lingual bone was 9.765mm for immediate implants and 6.25mm for delayed implants. The mean±SD change of bone reduction at second surgery was 1.28±0.31 for immediate implants and 3.01±0.33 for delayed implants. Unpaired t test was done for statistical analysis and p value was less than 0.05. So, the changes were statistically significant.
