BMP Effect on Implant Stability and Marginal Bone Level After Immediate Placement

May 9, 2026 updated by: Aya Adil Saeed

Evaluating the Effect of Bone Morphogenetic Protein on Dental Implant Stability and Marginal Bone Level Following Immediate Implant Placement (Randomized Controlled Study)

This randomized controlled clinical trial aims to evaluate the effect of recombinant human Bone Morphogenetic Protein-2 (rhBMP-2) on the stability and marginal bone level of dental implants following immediate placement.

patients requiring extraction of unrestorable tooth in upper incisors or premolar region will be randomly assigned into two groups: the experimental group will receive immediate implant placement with rhBMP-2 application, while the control group will receive immediate implant placement without rhBMP-2.

each group includes 16 immediate implants. Implant stability will be assessed using resonance frequency analysis (RFA) at baseline, and 16 weeks after implant placement. Marginal bone level changes will be evaluated radiographically using cone beam computed tomography (CBCT).

The study aims to determine whether the use of rhBMP-2 enhances osseointegration and reduces marginal bone loss compared with conventional immediate implant placement.
