Guided tissue regeneration procedures are intended to selectively favor healing by the periodontal ligament tissues. However, in most studies of the efficacy of guided tissue regeneration, nonresorbable barriers and membranes have been used, necessitating their surgical removal after a time. The present study employed a resorbable collagen barrier to treat Class II function invasions. The results of this treatment were compared with the results of conventional therapy. For most clinical parameters, there was no statistically significant difference in the results of treatment with or without collagen membranes. Sites treated with a collagen barrier did exhibit statistically significant improvement in probing depth and horizontal osseous support; however, these findings cannot be attributed entirely to the placement of the collagen membrane.
引导组织再生程序旨在选择性地促进牙周膜组织的愈合。然而，在大多数关于引导组织再生疗效的研究中，使用的是不可吸收的屏障和膜，一段时间后需要手术移除。本研究采用可吸收胶原屏障治疗II类功能侵犯。将该治疗结果与传统治疗结果进行比较。对于大多数临床参数，使用或不使用胶原膜治疗的结果在统计学上没有显著差异。用胶原屏障治疗的部位在探诊深度和水平骨支持方面确实有统计学上的显著改善；然而，这些发现不能完全归因于胶原膜的放置。
