Background: In dental prosthetics many advances have been achieved, but the great problem is still having with us: that is the resorption of the residual alveolar ridge and managing or preventing the secondary soft tissue changes brought on by bone loss. Objective: To evaluate the rate of resorption of alveolar ridge height of maxillary anterior arch in patients treated with immediate partial denture. Materials and Methods: This observational comparative study was conducted in the Department of Prosthodontics, Bangabandhu Sheikh Mujib Medical University for the duration of one year. On the basis of inclusion criteria patients were initially included in the study. A written informed consent was obtained from every patient. Study sample divided equally into two groups, Group A and Group B. Each group consists of 15 patients. Group A patients were treated with extraction of teeth followed by immediate denture prosthesis and group B patients were treated with extraction of teeth, but not provided by any prosthesis. Data were collected on the basis of alveolar bone resorption in the period of 1 month, 3 months and 6 months of extraction on a predesigned data collection sheet. Results: Mean vertical height at one month follow up was 25.48 (±2.41) mm in group A and 23.43 (±2.85) mm in group B which was statistically significant. Mean vertical height at three month follow up was 23 (±1.33) mm in group A and 22 (±2.99) mm in group B which was statistically significant. Mean vertical height of alveolar bone at six month follow up was 22.5 (±2.71) mm in group A and 21.5 (±3.18) mm in group B which was also statistically significant. Conclusion: Patient treated with immediate partial denture following extraction of teeth shows less alveolar bone resorption than patients treated without immediate partial denture.
