Designed and applicated a modified customized CAD-CAM socket-shield preparation guide template in immediate implant and followed up for 3 years.
Socket-shield technique could improve the esthetic effect of immediate implant restorations by preserving the labial fascicular bone-periodontal complex at the implant site. While the socket-shield technique is highly technique-sensitive. A modified customized CAD/CAM guided template was designed and fabricated by 3D printing. The movement of the carbide bur during preparing the socket-shield was limited by the socket-shield preparation template. In this case report, the socket-shield preparation template was used for preparing the socket-shield in the tooth root with irregular morphology and the case was followed up for 3 years.
The modified CAD/CAM socket-shield preparation template effectively improved the accuracy and efficiency of preparing the socket-shield by limiting the movement of the high-speed carbide bur in both in both lip-to-palatal and crown-to-root orientation. The socket-shield with accurate morphology could effectively maintain the gingival marginal level and contour.
The modified CAD/CAM socket-shield preparation template with the depth-locking ring effectively reduced the technique sensitivity and time consumption of the socket-shield technique, especially for tooth roots with irregular morphology.
设计并应用改良的定制计算机辅助设计与制造(CAD-CAM)牙槽窝屏障制备导板模板于即刻种植,并进行3年随访。
牙槽窝屏障技术可通过保留种植位点唇侧束状骨-牙周复合体来改善即刻种植修复的美学效果。然而,牙槽窝屏障技术对技术要求很高。通过3D打印设计并制作了改良的定制CAD/CAM导向模板。在制备牙槽窝屏障时,高速旋转的车针的移动受到牙槽窝屏障制备模板的限制。在本病例报告中,牙槽窝屏障制备模板用于形态不规则的牙根牙槽窝屏障的制备,并对该病例进行了3年随访。
改良的CAD/CAM牙槽窝屏障制备模板通过限制高速旋转车针在唇腭向和冠根向的移动,有效提高了牙槽窝屏障制备的准确性和效率。形态精确的牙槽窝屏障能够有效维持牙龈边缘水平和轮廓。
带有深度锁定环的改良CAD/CAM牙槽窝屏障制备模板有效降低了牙槽窝屏障技术的技术敏感性和时间消耗,尤其适用于形态不规则的牙根。
