clinical and radiographic methods of marginal bone loss evaluation after immediate implantation in post-extraction sockets.

Introduction: To achieve the best esthetic and functional results of implantation and patient satisfaction, different protocols of implant therapy have been recommended. Immediate implantation can provide the outcome faster than other protocols making it the treatment of choice. The rate of peri-implant bone resorption should be measured clinically and radiographically as bone support is a key factor in success of implant. Materials and Methods:  24 patients suitable for immediate implantation were selected. After atraumatic tooth extraction, the implant was placed and alveoloplasty was performed to reduce the implant-bone gap. A panoramic radiography was prepared 10 days after surgery and 3 months later on the day of healing cap insertion. The marginal bone loss was measured by subtractive technique. The clinical evaluation was done in same appointment by caliper. The software used for statistical analysis was SPSS 24. Result: The rate of bone resorption in radiographic evaluation was 0 to 0.30 mm whereas bone resorption was clinically reported at 0 -1 mm. Finally, the Paired T test showed no statistically significant difference (P = 0.296), but there was a positive and significant correlation (P = 0.026, R = 0.453), also the success rate in the evaluation of the results of the implant surgery was 100%. Conclusion: Based on the findings of this study, both methods for measuring bone analysis after implantation were acceptable and had a significant correlation. Therefore, the use of the less invasive method of radiological evaluation is recommended as a two-stage panoramic method.
