摘要: 为了探讨应用选区激光熔化快速成型技术直接制造个性化金属舌侧托槽的可行性,采用3维激光扫描仪采集与重建牙颌模型数据,并以该数字模型为基础,应用3维软件进行了个性化舌侧托槽的CAD设计,再通过自主研发的选区激光熔化快速成型机直接制造出个性化金属舌侧托槽,并对托槽的直接成型质量进行了理论分析和实验验证。结果表明,3维激光扫描仪获得的牙颌模型数据可以满足个性化舌侧托槽设计要求;应用选区激光熔化技术能够制造出与实际牙颌模型相一致的个性化舌侧托槽,取得了个性化前牙槽沟宽度为0.471mm±0.009mm数据,前牙槽沟宽度CAD设计值为0.460mm,两者间没有统计学上的差异(p0.05)。这一结果对选区激光熔化技术直接制造个性化金属舌侧托槽的实际应用是有帮助的。

Abstract: In order to investigate the feasibility of direct manufacturing customized lingual brackets by selective laser melting,firstly,a 3-D scanner was used to acquire and reconstruct teeth model,which was based on the customized lingual brackets designing with 3-D software;then customized metal lingual brackets were directly manufactured with a self-developed selective laser melting apparatus;finally the slot width of the bracket on front teeth was measured.The analysis shows that the teeth model obtained from the three dimensional laser scanner can meet the requirements for customized lingual brackets designing,and customized metal lingual brackets that can well fitted with teeth model can be produced precisely by selective laser melting process.Compared with the designed value 0.460mm on CAD model,the slot width of the front teeth was measured 0.471mm±0.009mm.The research proves it is feasible to manufacture precise and well fitted customized metal lingual brackets by means of selective laser melting technique.
