In a combined retrospective longitudinal study an evaluation of different dental and periodontal indexes (tooth mobility, probing pocket depth, plaque index, sulcus bleeding index, probing attachment level) in 62 patients with 77 resin-bonded bridges was performed. The direct comparison between test (abutment) and control (non-abutment) teeth revealed no differences at the day of evaluation in comparison to the date of incorporation. The longitudinal evaluation resulted in more favourable values at the day of evaluation in comparison to the date of incorporation for both the test and control teeth. Despite the altered contour of the abutment teeth, resin-bonded bridges seem not to change the periodontal status in a long-term evaluation, if good patient cooperation and regular care by a dental hygienist are guaranteed.
在一项回顾性纵向联合研究中，对62例患者的77颗树脂粘结桥进行了不同牙齿和牙周指数（牙齿松动度、探诊袋深度、菌斑指数、龈沟出血指数、探诊附着水平）的评估。测试（基牙）和对照（非基牙）牙齿之间的直接比较显示，与粘结时相比，评估日没有差异。纵向评估结果显示，与粘结时相比，测试牙和对照牙在评估日的值更为有利。尽管基牙外形发生了改变，但如果能保证患者良好的配合以及口腔保健员的定期护理，树脂粘结桥在长期评估中似乎不会改变牙周状况。
