研究4种牙周再生术式对牙周组织附着水平的影响。测试程序为：改良的Widman皮瓣手术、与先前冷冻的自体红骨髓和松质骨的移植相结合的改良的Widman皮瓣手术、与植入β-磷酸三钙和定期根规划和软组织刮除。使用8只成年恒河猴，分为4个相等组。以标准化的方式在对侧牙齿周围产生牙周袋。在每组动物中，对钳口一侧的囊袋进行上述手术治疗之一，而对侧囊袋保持为未手术对照。手术前3周，制定了精心设计的斑块控制程序，并持续到动物被处死12个月。手术后。在组织学切片中，从牙骨质-釉质交界（CEJ）到交界上皮（JE）的最顶端细胞，沿牙根表面进行沿着线性测量。然后比较手术和未手术部位的这些测量值。4种不同的再生程序后的愈合明显导致上皮衬里（长连接上皮）沿着治疗的牙根表面的重新形成，没有新的结缔组织附着。
The effect of 4 periodontal regenerative procedures on the connective tissue attachment level was studied. The procedures tested were: the modified Widman flap procedure, the modified Widman flap procedure combined with transplantation of previously frozen autogenous red marrow and cancellous bone, the modified Widman flap procedure in combination with implantation of .beta.-tricalcium phosphate and periodic root planning and soft tissue curettage. Eight adult Rhesus monkeys, divided into 4 equal groups, were used. Periodontal pockets were produced around contralateral teeth in a standardized manner. In each group of animals, the pockets on one side of the jaws were subjected to one of the above-mentioned surgical treatments, while the contralateral pockets remained as unoperated controls. Three wk before surgery, a carefully designed plaque control program was instituted and continued until the animals were sacrificed 12 mo. after surgery. In histologic sections, linear measurements along the root surfaces were made from the cemento-enamel junction (CEJ) to the most apical cells of the junctional epithelium (JE). These measurements from operated and unoperated sites were then compared. Healing following the 4 different regenerative procedures apparently resulted in the reformation of an epithelial lining (long junctional epithelium) along the treated root surfaces, with no new connective tissue attachment.
