Assessment of Labial Plate Thickness After Immediate Implant Placement Using Two Different Xenografts in the Esthetic Zone

Immediate implant placement in the esthetic zone has become a predictable treatment modality aiming to reduce treatment time while preserving alveolar bone and soft tissue architecture. However, dimensional alterations of the labial bone plate remain a clinical concern, particularly in Type II extraction sockets.

The present randomized controlled clinical trial will compare the effect of two different xenograft materials and de-epithelialized free gingival graft used for defect grafting during immediate implant placement. Eligible patients indicated for tooth extraction and immediate implant placement will be randomly assigned into two parallel groups based on the grafting material used.

Clinical evaluation and standardized radiographic assessment using CBCT will be performed to measure labial plate thickness changes, peri-implant bone stability, and implant success outcomes over a defined follow-up period. The findings of this study aim to provide clinical evidence regarding the most effective xenograft material for preserving peri-implant hard tissue contours in the esthetic zone
