文题释义:

口腔种植导板:按照患者口内CT扫描数据以及光学扫描数据,在计算机上重建患者下颌骨立体模型,根据最终义齿要求,确定患者口腔种植钉嵌入位置、数量、种植深度、钉倾斜角度等、生成科学精准的导板,以更好的指导临床牙种植效果。

数字化口腔牙种植技术:以微创技术为主导,利用全口CT扫描,获得相关数据,结合3D扫描仪导入牙模信息,在电脑中建立一个三维立体模型,并在种植软件中进行虚拟植入确立手术方案,再采用3D技术打印出能确保种植体植入位置、方向、深度的手术导航模板,在导板的辅助下实现精准、安全快速的手术。

 

背景:前牙区种植的难度较大,以往常规种植无法获得理想的效果。
目的:观察数字化快速成型种植导板修复上前牙种植的可行性。
方法:纳入需接受上前牙种植修复的患者80例,按照患者意愿选择治疗方案,分为2组,每组40例,分别实施常规种植修复治疗和数字化快速成型种植导板辅助修复治疗。测量植入后两组X,Y,Z 轴误差情况进行,随访12个月。
结果与结论:①植入后两组X,Y,Z 轴误差情况测量和比较:观察组在X,Y,Z 轴的误差均显著小于对照组(P < 0.05),植入后随访24个月,两组患者植入后前牙修复外观良好,未出现修复体松动等情况。②影像学复查:两组种植体周围均未观察到明显的骨吸收现象。③结果表明:上前牙区种植修复治疗过程中,应用数字化快速成型技术进行辅助治疗,可获得理想的治疗效果及更加精确的种植体植入位置。

Abstract:

BACKGROUND: Dental implantation in maxillary esthetic zone is difficult to achieve desired outcomes.
OBJECTIVE: To observe the feasibility of digital rapid prototyping implant template for anterior implantation.
METHODS: Eighty patients scheduled to receive anterior implant treatment were enrolled. According to the wishes of patients, they were divided into two groups, with 40 cases in each group, and were given routine implant treatment (control group) and digital rapid prototyping template-aided dental restoration (observation group). After implantation, the X-axis, Y-axis and Z-axis errors of the two groups were measured, and the patients were followed up for 12 months.
RESULTS AND CONCLUSION: After implantation, the errors of X, Y and Z axes in the observation group was significantly lower than those in the control group (P < 0.05); at 24 hours after implantation, patients in the two groups showed good appearance of the anterior tooth with no dental prosthesis loosing. Imaging examinations in the two groups showed no obvious bone resorption. These findings indicate that the aid therapy using digital rapid prototyping can obtain satisfactory therapeutic effect on anterior tooth restoration in the maxillary esthetic zone and precisely localize the dental implantation site.
