In modern dentistry, Computer-Aided Design and Manufacturing (CAD/CAM) is a promising technology that allows fabrication of prosthetic restorations through milling procedures. Over years, with the continuous improvement of technology, direct CAD/CAM or "chairside" technology is becoming a widespread approach which offers immediate rehabilitation with long-term rates reported by several studies compared to conventional techniques. All steps are generally carried out in the dental office during the same treatment session. The present paper is about a healthy female patient with a decayed 36 tooth which was restored by ceramic onlay using Planmeca's PlanCAD system. Through the present clinical case, a detailed protocol of chairside technology would be presented from the digital impression to the milling process. It would detail impression steps. It would also highlight especially the virtual design confection of prosthetic restoration using a biogeneric model included in the software. It also illustrated tools which could be used by the dentist to perform the design. Also, some useful tips would be presented in order to perform the confection. On this subject, various studies showed the viability of such technology. To summarize, referring to previous studies, this promising technology allows especially time-saving and patient's comfort compared to the indirect one.
在现代牙科领域,计算机辅助设计与制造(CAD/CAM)是一项很有前景的技术,它能够通过铣削工艺制作修复体。多年来,随着技术的不断进步,直接CAD/CAM即“椅旁”技术正成为一种广泛应用的方法,与传统技术相比,多项研究报告显示该技术能实现即刻修复且具有长期效果。通常所有步骤都在牙科诊所的同一治疗过程中完成。本文讲述的是一位健康女性患者,其36号牙龋坏,采用普兰梅卡公司的PlanCAD系统制作陶瓷嵌体进行修复。通过这个临床病例,将展示从数字印模到铣削过程的椅旁技术详细流程。会详述印模步骤。还将特别强调使用软件中包含的生物通用模型进行修复体的虚拟设计制作。也会说明牙医可用于进行设计的工具。此外,还会给出一些进行制作的实用技巧。关于这个主题,多项研究表明了此类技术的可行性。总之,参照以往研究,与间接技术相比,这项有前景的技术尤其节省时间且能让患者更舒适。
