目的探讨双种植体支持杆卡式覆盖总义齿用于修复下颌严重吸收病例的可行性。方法回顾2004~2015年修复的16例患者,分析其修复效果,包括戴牙后调改频率、患者使用体验和使用周期、杆卡可靠性。结果覆盖义齿戴牙后固位稳定好、调改频率少、3年内不需重衬、杆卡可靠不易折断。结论双种植体粘膜支持式杆卡覆盖总义齿用于修复下颌牙槽骨严重吸收病例有非常可靠的效果。
Objective To investigate the feasibility of using two-implant support rod-type card-covered general dentures in the repair of severe mandibular ablation. Methods The clinical data of 16 patients who were repaired from 2004 to 2015 were retrospectively analyzed, including the frequency of modification after wearing a tooth, the patient experience and the period of use, and the reliability of the card. Results overdenture teeth wear stable, good frequency, less than three years without lining, rod is not easy to break the reliable. Conclusion The double implants with muco-membrane-supported bar-card covers the total denture and has a very reliable effect in the treatment of severe cases of mandibular alveolar bone resorption.
