Standard- and Micro-Dose rhBMP-2 for Implant Stability, Marginal Bone Loss, and Postoperative Sequelae: A Double-Blind Randomized Controlled Trial
Sponsor: University of Baghdad
Summary
This study will compare the effect of standard-dose and micro-dose recombinant human bone morphogenetic protein-2 (rhBMP-2) with a placebo control on dental implant stability in the posterior mandible. Sixty patients requiring a single dental implant will be randomly assigned to one of three groups: standard-dose rhBMP-2, micro-dose rhBMP-2, or sterile saline only. Implant stability will be measured using Resonance Frequency Analysis at baseline, 2 weeks, 4 weeks, and 12 weeks. Marginal bone loss, peri-implant bone density, ectopic bone formation, and postoperative sequelae including swelling, pain, trismus, and soft tissue healing will also be evaluated during follow-up. The aim is to determine whether micro-dose rhBMP-2 can improve implant stability while reducing postoperative complications compared with the standard dose.

Interventions
Standard-dose rhBMP-2
Standard-dose recombinant human bone morphogenetic protein-2 (rhBMP-2) is locally applied into the implant osteotomy immediately before implant placement at the manufacturer's recommended dose to enhance osseointegration and implant stability.
Micro-dose rhBMP-2
Micro-dose recombinant human bone morphogenetic protein-2 (rhBMP-2) is locally applied into the implant osteotomy immediately before implant placement at a reduced dose to evaluate whether comparable implant stability can be achieved with fewer dose-related adverse effects.
Sterile Normal Saline
Sterile normal saline is locally applied into the implant osteotomy immediately before implant placement as the placebo control.
