干预措施:

将口扫数据导入设计软件后,在临时牙解剖形态设计中将临时牙颌面A、B区与对颌牙的最小间隙为40μm,咬合面其他区域与对颌牙的最小间隙设为120μm。将3D打印的临时修复体在术后48小时内佩带入患者口内,试戴时用咬合纸检查咬合,满足分组要求时,在牙尖交错位,用40μm厚的咬合纸可有阻力地拉出,而用100μm厚的咬合纸在A颊尖颊斜面处及B颊尖舌斜面处有均匀咬合印记,在侧方运动时,牙合面无咬合印记。

干预措施代码:

Intervention:

After importing oral scanning data into the design software, the minimum gap between area A and area B of the temporal jaw and the adjacent jaw is 40 μm in the design of the temporal dental anatomy, and the minimum gap of other areas of the bite surface and the adjadjacent jaw is 120 μm. The 3D printed temporary prostheses were worn into the patient's mouth within 48 hours after surgery, and the occlusal was checked with an occlusal paper when trying on. When the grouping requirements are met, at the intersection of the teeth, a 40 μm thick biting paper can be pulled out with resistance, while a 100 μm long biting paper has a uniform biting mark on the diagonal of cheek-tip A and the diagonal tongue of cheek tip B. When lateral motion, there is no bite mark on the palate.

The 3D printed temporary prostheses were worn into the patient's mouth within 48 hours after surgery, and the occlusal was checked with an occlusal paper when trying on. When meeting the grouping requirements, in the intersection of the teeth, a 40 μm thick biting paper can be pulled out with resistance, while a 100 μm long biting paper has a uniform biting mark on the slope of cheek-tip B and cheek-tips C. When moving sideways, there is no bite mark on the palate.

After importing oral scanning data into the design software, the minimum gap between area A, B, and C of the temporal tooth's jaw area and the adjacent jaw area is set at 40 μm in the design of the temporal teeth anatomy. The minimum gap among other areas of the bite area and theadjacent jaw area is fixed at 120 μm. The 3D printed temporary prostheses were worn into the patient's mouth within 48 hours after surgery, and the occlusal was checked with an occlusal paper when trying on. When meeting the grouping requirements, in the intersection of the teeth, a 40 μm thick biting paper can be pulled out with resistance, while a 100 μm long biting paper has a uniform biting mark on the cheek slope of cheek A, cheek narrow of cheek B and cheek slop of cheek C.

Intervention:

After importing the dental scan data into the design software, the minimum gap between the maxillofacial and the maxillary teeth was 100 μ m in the design of the provisional tooth anatomy. The 3D printed temporary repair body is worn into the patient's mouth within 48 hours after surgery. When it is tested, the bite is examined with a biting paper. When meeting the group requirements, when the dental points are crossed and when the side moves, the biting paper 100 μm thick can be pulled out with resistance. There is no bite mark on the bite surface.
