目的:观察上颌骨缺损修复中采用附着体或套筒冠方式增加赝复体固位和稳定的作用。方法:对4例上颌骨缺损患者可利用的残根、残冠或因不能耐受拔牙而保留的残根、残冠进行完善的根管治疗,制作附着体和套筒冠,利用此作为固位装置进行上颌骨缺损的赝复体修复。结果:残根、残冠的利用和附着体及套筒冠修复可增加赝复体的固位和稳定,赝复体在行使功能时无松动。结论:采用附着体和套筒冠修复方式,充分利用残根、残冠固位,可提高赝复体的固位和稳定。
AIM:To achieve a favorable level of retention and stability of maxillary obturator prostheses by using attachments and telescopic crowns in the repair of maxillary obturator prostheses. METHODS:Attachments and telescopic crowns were fabricated on residual roots and crowns with complete root canal therapy and periotherapy in 4 patients,and they were used as retainers for the repair of maxillary obturator prostheses. RESULTS:The usage of attachments and telescopic crowns fabricated on residual roots and crowns could improve the retention and stability of maxillary obturator prostheses.There was no movement when prostheses performing functions. CONCLUSION:Residual roots and crowns can be reserved and improve the retention and stability of maxillary obturator prostheses by fabricated with attachments and telescopic crowns in clinic.
