摘要
目的探讨组合桩嵌体冠应用于磨牙残冠保存修复的临床应用。方法对23例患者35颗磨牙残冠制作组合桩嵌体冠,以较粗直根管作为分体桩根管,再选择一根管作为辅助固位桩且制作嵌体冠,分体桩插入嵌体冠预留的孔道固位。随防2~4年统计生存率,并且采用改良USPHS系统各项标准对2年的随访结果对咬合关系、邻接关系、边缘密合度、继发龋、松动等进行评估。结果随访21例患者31颗修复体,2年生存率为100%。失访2例4颗修复体。所有修复体无松动,咬合关系、邻接关系、边缘密合度良好,基牙无继发龋、松动。结论组合桩嵌体冠对磨牙残冠修复好,可有效地保存残冠,恢复患牙的功能。
Objective To explore the clinical application of combined post core inlay-crown to restoration residual crown of the molar. Methods Combined post core inlay-crowns were made for 35 residual crown of molar from 23 pa- tient, the first, separate post were made by the bigger straight root canal, the second, inlay-crown and supplementary retention post were made by one root canal, the part were fixed by separate post to insert the prepared root canal. All case were followed up for 2-4 year for counting survival rate, and the results of 2 years were evaluated by modified USPHS to analysis marginal adaptation, secondary caries, proximal contact relationship, function of occlusion, and loose. Results Except 4 restoration from 2 patients who were failed to be tracked during the follow up period, the 31 restorations of remaining 21 patients were followed up for 2 years, the survival were 100%, the relationship of proximal contact and function of occlusion and rate of all of restorations for 2 years marginal adaptation of all restoration were good condition, there is no any loose, and no secondary caries and loose in abutment. Conclusion The effect of combined post core inlay- crown to restoration residual crown of the molar is good, it can effectively reserve the resid- ual crown, and improve the function of teeth with defect.
