简要总结
To compare the healing of intrabony periodontal defects treated with either open flap debridement and a volume-stable collagen matrix (VCMX) or a deproteinized bovine bone mineral with 10% collagen. The results will shed light on the clinical potential of VCMX in regenerative periodontal surgery and help to develop new treatment strategies.
