A patient of 58 years of age without medical problems came to the clinic due to missing teeth in the upper posterior region and to change the partial fixed prosthesis in the upper anterior area. Proposed treatment: surgical phase of three conical shape tapering implants with prosthetic platform in occlusal direction with mechanize collar tissue level with fixtures to place implant-supported metal-ceramic restorations. In the anterior area, a zirconium oxide fixed partial prosthesis was vertical preparation of the tooth's. When preparing teeth to receive fixed prostheses, the definition and shape of finish lines has been a subject of endless discussion, modification, and change ever since the beginnings of restorative prosthetic dentistry. The BOPT technique (biologically oriented preparation technique) was first described in the context of tooth-supported restorations but has recently been applied to dental implants with the aim of ensuring healthy peri-implant tissue and creating the possibility of modeling the peri-implant sulcus by modifying prosthetic emergence profiles. Vertical preparation of teeth and abutments without finish line on implants is a technique which was found to be adequate for ensuring the remodeling and stability of peri-implant tissues. Peri-implant tissue health, shoulderless abutments.
一位58岁、无健康问题的患者因上颌后牙区牙齿缺失以及更换上前牙区的部分固定义齿前来诊所。建议治疗方案：植入3颗圆锥形渐缩种植体的手术阶段，种植体带有向咬合方向的修复平台，采用机械加工颈圈组织水平式种植体，以放置种植体支持的金属烤瓷修复体。在前牙区，制作了一个氧化锆固定局部义齿，对牙齿进行了垂直预备。自从修复性假牙修复学诞生以来，在为接受固定义齿而预备牙齿时，终印模的定义和形状一直是无休止的讨论、修改和变化的主题。生物导向预备技术（BOPT）最初是在牙支持修复的背景下描述的，但最近已应用于牙种植体，目的是确保种植体周围组织健康，并通过修改修复体的龈缘外形来塑造种植体周围龈沟。对种植体上的牙齿和基牙进行无终印模的垂直预备是一种被发现足以确保种植体周围组织重塑和稳定的技术。种植体周围组织健康，无肩台基牙。
