To study the influence of splints on periodontal tissues, Obwegeser and Merkx splints were applied to beagles. Histological evaluation was performed after splinting periods of 48 h and 6 weeks. After 48 h, gingivitis had developed when using both types of splints. After 6 weeks, the adverse effects of the splints were more predominant. Gingivitis had become severe and mild periodonitis had developed. In the case of Merkx splints, the periodontal ligament appeared to be somewhat less affected but the condition of the gingiva appeared to be somewhat worse than in the case with Obwegeser splints. For both types of splints, it is important that clinical application should be attended by measures not only to reduce plaque accumulation, but also to minimize trauma due to their application and continuous mechanical irritation of the tissues.
为研究夹板对牙周组织的影响，将Obwegeser夹板和Merkx夹板应用于比格犬。在夹板固定48小时和6周后进行组织学评估。48小时后，使用两种类型的夹板时均出现了牙龈炎。6周后，夹板的不良反应更为明显。牙龈炎变得严重，轻度牙周炎已经发展。在使用Merkx夹板的情况下，牙周膜似乎受影响较小，但牙龈状况似乎比使用Obwegeser夹板的情况稍差。对于这两种类型的夹板，重要的是临床应用时不仅要有措施减少菌斑积聚，还要尽量减少因夹板应用及组织持续机械刺激而造成的创伤。
