本临床和放射学研究评估了引导组织再生技术（GTR）联合羟基磷灰石-胶原同种异体移植材料（HAC）治疗3+2+1壁联合骨内缺损的愈合情况，并与单独HAC和传统皮瓣手术（CF）进行了比较。本文对18例35 ~ 60岁的成人牙周炎患者进行了近端缺损40例的治疗。非手术治疗后，将缺损随机分为4组，每组10个缺损。这些组被命名为：(1)膨胀聚四氟乙烯膜（e-PTFE）， (2) e-PTFE+HAC,(3)单独HAC和(4)CF。在6个月时，记录了以下参数的变化。各组平均PPD减少量分别为5.83、5.85、3.80、3.17 mm。各组PPD均显著降低(p
This clinical and radiological study evaluated the healing of 3+2+1 wall-combined intrabony defects treated using the guided tissue regeneration technique (GTR) with and without hydroxyapatite-collagen alloplastic graft materials (HAC), in comparison to that of HAC alone and conventional flap surgery (CF). 40 interproximal defects with probing depth >6 mm were treated in 18 adult periodontitis patients of ages 35-60 years. After non-surgical therapy, the defects were randomly grouped into 4 groups of 10 defects each. These groups were designated: (1) expanded polytetrafluoroethylene membrane (e-PTFE), (2) e-PTFE+HAC, (3) HAC alone and (4) CF. At 6 months, the following changes in parameters were recorded. Mean PPD reduction for each group was 5.83, 5.85, 3.80 and 3.17 mm respectively. PPD reduced very significantly in all groups (p
