A 40-year-old woman with natural teeth in the upper jaw and a complete lower denture was treated with six osseointegrated implants connected to a fixed bridge. On a recall visit 6 months posttreatment an air powder abrasive devise Prophy-Jet had been used to remove calculus and debris from the titanium abutments by the referring dentist. This resulted in an acute clinical reaction characterized by pain and submucosal emphysema. Furthermore, radiographs revealed break down of the marginal bone surrounding the fixtures. The treatment and follow-up period became long. These observations suggest that the use of air powder abrasive instruments is not the treatment of choice in the maintenance care of osseointegrated titanium implants.
一名40岁女性,上颌为天然牙,下颌为全口义齿,接受了6枚骨结合种植体连接的固定桥修复治疗。治疗后6个月复诊时,转诊牙医使用了空气喷砂洁治器Prophy-Jet清除钛基台上的牙结石和碎屑。这导致了以疼痛和黏膜下气肿为特征的急性临床反应。此外,X线片显示种植体周围边缘骨吸收。治疗和随访期延长。这些观察结果表明,在骨结合钛种植体的维护护理中,空气喷砂器械并非首选治疗方法。
