In order to improve fit and comfort, a maxillary protraction facemask customized to the patient's anatomy was produced by means of 3D face scanning, digital design and additive manufacturing. An 8-year-old patient in need of early treatment for the Class III malocclusion received a rapid palatal expander and a Petit-type facemask, whose components were digitally designed on a 3D scan of the patient's face. For face scanning, the iPad Pro 2018 tablet (Apple, Cupertino, CA, USA) with the Bellus3D DentalPro application (Bellus3D, Campbell, CA, USA) was used. Facemask components were modelled with 3D Blender software. The rests were 3D printed in BioMed Clear biocompatible resin (Formlabs, Somerville, MA, USA), and the bar in stainless steel. For greater comfort, the internal surface of the rests was lined with a polymer gel pad (Silipos, Niagara Falls, NY, USA). The manufacturing procedure of the customized facemask is patented. The patient wore the facemask at night for a period of 9 months. The patient's experience was evaluated with a questionnaire at 1 week, 3, 6, and 10 months of treatment. The customized facemask was well accepted by the patient and obtained the expected treatment outcome. Furthermore, 3D face scanning, 3D modelling and 3D printing allow for the manufacturing of customized facemasks with improved fit and comfort, favoring patient compliance and treatment success.
为了提高贴合度和舒适度，通过3D面部扫描、数字设计和增材制造制作了一款根据患者解剖结构定制的上颌前牵引面罩。一名需要早期治疗III类错牙合畸形的8岁患者接受了快速腭扩展器和Petit型面罩，其组件是在患者面部的3D扫描上进行数字设计的。面部扫描使用了配备Bellus3D DentalPro应用程序（美国加利福尼亚州坎贝尔市Bellus3D公司）的2018款iPad Pro平板电脑（美国加利福尼亚州库比蒂诺市苹果公司）。面罩组件使用3D Blender软件进行建模。托槽采用生物医学透明生物相容性树脂（美国马萨诸塞州萨默维尔市Formlabs公司）进行3D打印，横杆采用不锈钢材质。为了提高舒适度，托槽的内表面衬有聚合物凝胶垫（美国纽约州尼亚加拉瀑布市Silipos公司）。定制面罩的制造工艺已获专利。患者在夜间佩戴面罩9个月。在治疗的第1周、3个月、6个月和10个月通过问卷调查评估患者的体验。定制面罩得到了患者的良好接受，并取得了预期的治疗效果。此外，3D面部扫描、3D建模和3D打印能够制造出贴合度和舒适度更高的定制面罩，有利于患者的依从性和治疗成功。
