In this paper the occlusal reduction for a single crown is studied. After a brief description of the classical techniques and usual instruments, an analysis of the different malocclusions demonstrates that the reduction has to be made in accordance with each individual case. Afterwards, the author presents a new diamond with an original profile which shows a concave working side limited by two spherical parts. With this profile an ideal prepared occlusal surface can be obtained with only one passage of the bur. The preparation of the occlusal surface with this instrument is then analysed step by step, showing how a real sculpture of this surface can be achieved rapidly and with ease. A clinical case demonstrates the results.
本文对单冠修复的咬合面预备进行了研究。在简要介绍经典技术和常用器械之后，对不同错颌畸形的分析表明，咬合面预备必须根据每个具体病例进行。随后，作者介绍了一种具有独特外形的新型金刚砂车针，其工作侧呈凹形，由两个球形部分限定。使用这种外形，仅通过车针一次切割就能获得理想的预备咬合面。然后逐步分析了使用该器械进行咬合面预备的过程，展示了如何快速轻松地实现该表面的精细塑形。一个临床病例展示了相关结果。
