Immediate Implant Placement Using Volume-Stable Collagen Matrix Combined With rhPDGF-BB

Not Applicable
Withdrawn
Conditions
Tooth Extraction
Immediate Implant Placement
Registration Number
NCT06038695
Lead Sponsor
I-Ching Wang
Brief Summary

The goal of this study is to test a volume-stable collagen matrix in combination with recombinant human platelet-derived growth factor-BB, specifically in patients who have an immediate implant placement for teeth #5-#12.

The main question this study aims to answer is does the recombinant human platelet-derived growth factor-BB accelerate the formation of blood vessels and augment tissue volume around the immediate implant.

Participants will be asked to undergo immediate implant placement using volume-stable collagen matrix in combination with recombinant human platelet-derived growth factor-BB, as well as attend 11 study visits over the course of 1.25 years.
