目的

探讨聚醚酮酮(PEKK)数字化乳牙早失间隙保持器的临床应用效果。

方法

从2019年4—5月在南京大学医学院附属口腔医院儿童口腔科就诊的6~10岁儿童中选取下颌单侧乳磨牙早失患者共5例,其中男2例、女3例,经数字化口内光学印模制取,间隙保持器数字化设计,PEKK基材间隙保持器的数字化制作,口内试戴调整,粘接。

结果

5例患儿的数字化乳牙早失间隙保持器重量只有传统金属带环丝圈保持器的25%,设计和制作时间只需1 h,5例数字化间隙保持器口内观察与基牙吻合度高。

结论

数字化乳牙早失间隙保持器采用数字化口内印模法比传统藻酸盐印模法提高了患儿的舒适度,可当日设计完成并佩戴,并使用PEKK材料,实现了间隙保持器去金属化,无金属过敏等风险,兼顾了美观的效果,具有较好的临床应用前景。

Objective

The purpose of this study was to investigate the clinical effect of polyetherketoneketone (PEKK) digital space maintainer for early loss of deciduous teeth.

Methods

In the study, five children (male 2, female 3) with unilateral loss of either first or second molars were enrolled from our hospital in accordance with the inclusion criteria. After the enrollment of patients, their digital intraoral impressions were obtained by using a intraoral scanning system, and imported directly into 3Shape Dental Design software system. Space maintainer (band with loop) device was designed by CAD (Computer-Aided Design) software, and manufactured by milling of the PEKK blocks. The digital space maintainer was adjusted first on the definitive cast and then intraorally, and cemented on the abutment teeth.

Results

The digital space maintainers fabricated by PEKK for deciduous premature loss in five children were 75% lighter than the conventional one. The design and fabrication process only took 1 hour and thus could be delivered within the same day. The intraoral scans were consistent with the abutment teeth.

Conclusions

The digital space maintainer fabricated by PEKK could shorten patients’ waiting time, which could be completed on the same day, and improved the comfort of the children. The suitability of space maintainer was improved by the digital workflow and fabricated by PEKK. The digital space maintainer was fabricated with no metal with improved aesthetics. There was a good clinical application prospect for digital space maintainer fabricated by PEKK for premature loss of deciduous teeth.
