In patients with severe peridontitis, lower incisors are prone to terminal breakdown. This study assessed the longevity of composite-bonded resin/natural teeth (reinforced only with a stainless steel mesh) as replacements for periodontally lost lower incisors.
Besides the longevity of the restoration, the periodontal condition of the abutment teeth, and the general satisfaction of the patient were evaluated retrospectively via a phone interview, in combination with an analysis of the patient's clinical dental file.
The cumulative proportion of survival rate of these composite restorations was 80% after 5 years of function. No statistically significant difference was found between the survival distribution of one- and two-pontic bridges (P = 0.66). The abutment teeth demonstrated stable probing depths and a negligible loss in attachment (0.1 mm/year). The satisfaction ratings were also favorable.
The data seem to suggest that composite bonding of 1 or 2 teeth can be considered a semi-permanent rehabilitation for the replacement of 1 or 2 periodontally lost lower incisors.
在重度牙周炎患者中，下前牙容易出现最终损坏。本研究评估了复合树脂粘结/天然牙（仅用不锈钢网加强）替代因牙周病缺失的下前牙的使用寿命。
除了修复体的使用寿命外，还通过电话访谈结合患者临床牙科档案分析，对基牙的牙周状况和患者的总体满意度进行了回顾性评估。
这些复合修复体在功能使用5年后的累积生存率为80%。单桥和双桥的生存分布之间未发现统计学上的显著差异（P = 0.66）。基牙的探诊深度稳定，附着丧失可忽略不计（每年0.1毫米）。满意度评分也很高。
数据似乎表明，1颗或2颗牙齿的复合粘结可被视为替代1颗或2颗因牙周病缺失的下前牙的半永久性修复方法。
