目的：本研究的目的是调查修复治疗后 6 个月内近端接触紧密度的变化。材料和方法：在一项随机临床试验中，52 名患者植入了 II 类复合树脂修复体。在治疗前、治疗后立即和治疗后 6 个月测量近端接触紧度。使用线性回归和 t 检验对这些数据进行统计分析。 结果：治疗后紧张度增加的近端接触在 6 个月后往往会松动，但仍比治疗前更紧张。治疗后减少的近端接触量在 6 个月后几乎没有变化。结论：修复治疗后接触紧密度的变化并不总是随着时间的推移保持稳定。 (c) 2006 Elsevier Ltd. 保留所有权利。
Objective: The aim of this study was to investigate changes in proximal contact tightness up to 6 months after the restorative treatment.Materials and methods: In a randomised clinical trial Class II composite resin restorations were placed in 52 patients. Proximal contact tightness was measured before, directly after, and 6 months after treatment. These data were analysed statistically using linear regression and t-tests.Results: Proximal contacts, that increased in tightness as result of the treatment tend to loose tightness after a 6-months period but remain tighter than before treatment. Proximal contacts, that decreased after treatment hardly change after 6 months. Conclusions: A change in contact tightness after restorative treatment will not always remain stable over time.
