Computer-aided design and computer-aided manufacturing (CAD/CAM) dentistry have significantly changed workflows in recent years. Restorations and devices can now be digitally designed and 3D-printed for dental care purposes. This clinical case report provides straightforward protocols for the digital design and 3D manufacture of gingivectomy and tooth preparation guides. These types of guides improved the gingival architecture of the anterior teeth and provided controllable tooth preparations prior to labial ceramic veneers. Thoughtful clinical evaluation started with listening to the patient's chief complaint and extra- and intra-oral evaluations. Then a digital wax-up was performed, followed by an intra-oral mock-up, to evaluate the shape of the proposed restorations. After patient acceptance, the clinical procedure started with the gingivectomy and tooth preparation. Hand-crafted porcelain veneers were bonded under rubber dam isolation to avoid any contamination and maximize the bonding protocol. The esthetic and functional demands were fully satisfied. Predictable outcomes can be obtained whenever a meticulous evaluation and execution of all the steps are performed. Three dimensional printing technology allows the fabrication of devices such as gingivectomy and tooth reduction guides that help accomplish the desired results.
近年来,计算机辅助设计与计算机辅助制造(CAD/CAM)牙科技术极大地改变了工作流程。如今,修复体和器械可通过数字化设计并3D打印用于牙科治疗。本临床病例报告提供了牙龈切除术和牙体预备导板数字化设计与3D制造的直接方案。这类导板改善了前牙的牙龈结构,并在唇侧陶瓷贴面修复前提供了可控的牙体预备。周全的临床评估始于倾听患者的主诉以及口外和口内检查。然后进行数字化牙合堤制作,接着进行口内模型制作,以评估拟议修复体的外形。在患者认可后,临床操作从牙龈切除术和牙体预备开始。手工制作的瓷贴面在橡皮障隔离下粘结,以避免任何污染并最大化粘结流程。美学和功能需求得到了充分满足。只要对所有步骤进行细致的评估和执行,就能获得可预测的结果。三维打印技术能够制造诸如牙龈切除术和牙体预备导板等器械,有助于实现预期效果。
