Effect of three different grafting materials on immediate implant placement using vestibular socket therapy in class...

This study compared the effectiveness of three bone grafting materials used for treating class II fresh extraction sockets in the esthetic zone with immediate implant placement using Vestibular Socket Therapy (VST) to evaluate the pink esthetic score (PES), peri-implant mucosal levels (PML), and facial bone thickness (FBT).

Twenty-four surgical sites in the maxillary anterior region presented with type II socket defects received immediate implants and simultaneous bone grafting with either a collagen plug soaked in blood, demineralized bone matrix Grafton, or a particulate mixture of 2/3 autogenous bone chips and 1/3 deproteinized bovine bone mineral MinerOss X. The outcome measures were evaluated at 6 and 12 months. The study was registered on www.

gov (12/07/2021 - ID: NCT04957654).

Twenty-two cases (91.6%) showed a total PES score of > 10, without a significant difference between all groups. The vertical height soft tissue changes showed significant improvement in the Collagen plug and Grafton groups at 6 and 12 months, while MinerOss X showed no significant difference at 6 and 12 months compared to baseline. Radiographically, FBT was 0.72 ± 0.20, 0.44 ± 0.12, and 0.95 ± 0.37 at baseline, which significantly increased to 1.61 ± 0.88, 1.48 ± 1.20 and 2.31 ± 0.86 at 12 months for all three groups, respectively.

The use of a particulate bone graft mixture significantly increases the FBT compared to collagen plugs and DBM-Grafton when performing VST during immediate implant placement in compromised Class II extraction sockets.
