目的 观察新型树脂水门汀用于钴铬合金马里兰桥修复单颗牙缺失的短期疗效.方法 2015年6月至2016年6月在吉林大学口腔医院VIP综合科就诊的单颗牙缺失患者12例,应用钴铬合金马里兰桥进行修复,试戴后采用新型树脂水门汀RelyXTM Ultimate进行粘接.结果 12例修复体平均临床观察时间为12个月,最长临床观察时间为18个月.1例修复体发生脱落,重新粘接后使用良好.所有基牙未发现牙龈炎和继发龋.结论 新型树脂水门汀用于钴铬合金马里兰桥修复单颗牙缺失的短期临床效果良好,粘接效果可靠,操作步骤简便,但能否满足临床长期要求仍须进一步观察.%Objective To observe the short-term clinical effect of a new type resin cement on restoring single tooth loss with cobalt-chromium alloy resin-bonded bridge.Methods Twelve patients with single tooth loss were selected.The cobalt-chromium alloy resin-bonded bridges were used to restore the missing teeth.After try-in,RelyXTM Ultimate was applied to adhere the resin-bonded bridge and the abutments.Results The mean survival period of 12 dentures was 12 months,and the maximum was 18 months.Only one denture was debonded,and it has been resumed well after rebonding.No gingivitis or secondary caries was found in all of the abutments.Conclusion The new type resin cement shows favorable short-term clinical effect on restoring single tooth loss,with reliable bonding effect and easy operating steps.However,further observation is still needed to ascertain its long-term clinical effect.
