Abstract

Background: This study aimed to evaluate alveolar socket preservation using mineralized plasmatic matrix (MPM) with or without pontic shield in the anterior maxilla. Materials and Methods: Twenty-seven non-restorable maxillary anterior teeth indicated for extraction were randomly divided into three equal groups. Group I underwent extraction only. Group II received MPM grafting. Group III received MPM with pontic shield technique. CBCT was used at baseline and after 4 months to assess ridge width, height, and bone density. Soft tissue healing was evaluated at 7, 14, and 21 days using the Landry index. Results: A statistically significant difference in ridge width reduction was observed at 3 mm apical to the crest (p < 0.05), with no significant difference at 6 mm (p > 0.05). Buccal bone height reduction differed significantly (p < 0.05), unlike palatal height reduction (p > 0.05). Bone density decreased significantly over time in MPM groups, with no intergroup difference at follow-up. Soft tissue healing showed no significant intergroup differences (p > 0.05), but MPM sites exhibited clinically favorable healing. Conclusion: Combining MPM with the pontic shield technique resulted in superior preservation of ridge dimensions and enhanced soft tissue healing compared to MPM alone or ungrafted sockets.
