To maintain osseointegration, it is essential that the prosthesis fit with total passivity because the absence of a periodontal ligament makes the implant unable to adapt its position to a nonpassive framework. The traditional system of building a metal framework by melting over mechanized pieces--called gold cylinders in the Brånemark system--has been modified so these pieces are joined to the metal framework by means of physicochemical bonding. This bond is achieved by treating the metallic surfaces with a Silicoater system and a composite resin cement that sets in the mouth using an improved cementing protocol. In this paper, the clinical viability of this new philosophy, shown over 2 years, is presented. A total of 64 prostheses (39 maxillary and 25 mandibular) supported by 214 abutments, with an average observation period of 9 months, were evaluated. The results show that it is possible to routinely obtain a ceramometal prosthesis with a totally passive circular fitting while maintaining the possibility of retrieval, thus making postceramic soldering unnecessary.
为维持骨结合，假体必须完全被动适配，因为缺乏牙周膜会使种植体无法将其位置调整至非被动框架。传统的通过在机械部件（在Brånemark系统中称为金柱）上熔铸来构建金属框架的系统已得到改进，这些部件通过物理化学结合与金属框架相连。这种结合是通过使用Silicoater系统处理金属表面以及使用改进的粘结方案在口腔中凝固的复合树脂粘结剂来实现的。本文展示了这种新理念在两年多时间里的临床可行性。共评估了由214个基台支持的64个假体（39个上颌和25个下颌），平均观察期为9个月。结果表明，常规情况下可以获得具有完全被动圆形适配的烤瓷熔附金属假体，同时保持可取出性，从而无需进行烤瓷后焊接。
