摘要

背景:一个71岁的女性提出了一个左侧下颌骨间隙脓肿。这是由于她的下颌假牙舌缘的大量结石堆积导致口腔底部溃疡。自从54年前拔下义肢作为即时义齿以来,她一直没有取出义肢。在陈述时,她不能取出她的义齿,因为牙石锁定了义齿在舌下切口。假牙在中线处切开取出,并通过颈部切口排出下颌下脓肿。结果:在移除义齿之前,患者非常稳定,并享受了长时间的无问题义齿佩戴,并从中获得了特殊的价值。令人惊讶的是,下颌牙槽骨吸收也很少。结论:该病例表明,如果下义齿不取出超过半个世纪,可能会发生什么。舌缘上的牙石为义齿提供了稳定性和固位,它似乎保护了牙脊不被吸收。虽然牙石可能给她的下假牙带来了一些意想不到的好处,但最终导致了严重的感染。

Case report: a patient who had not removed her lower denture for 54 years.

Background: A 71-year-old female presented with a left submandibular space abscess. This was found to be due to large accumulations of calculus on the lingual flanges of her lower denture ulcerating the floor of the mouth. She had not taken the prosthesis out since it was provided as an immediate denture after extractions 54 years previously. At presentation she could not take her denture out as the calculus locked the denture under lingual undercuts. The denture was sectioned in the midline to remove it and the submandibular abscess was drained via a neck incision.

Findings: Prior to removal the denture was remarkably stable and she had enjoyed a long period of problem free denture wearing and had had exceptional value from it. There was also surprisingly little mandibular alveolar bone resorption.

Conclusion: The case demonstrates what may happen if a lower denture is not taken out for over half a century. The calculus on the lingual flanges provided both stability and retention for the denture, and it appeared to have protected the ridge from resorption. While the calculus may have provided some surprising benefits to her lower denture it ultimately led to a serious infection.
