Extra-oral implants have been used for well-defined application for nearly 20 years; for tupoorting maxillo-facial prostheses and for bone anchored hearing aids (BAHA). In both of these applications, the bone-anchored prostheses support transcutaneous abutments. It is the junction between the implant and the abutment which ensures, given certain preconditions, the permanent percutaneous connection (PPC). The authors describe the two types of implants currently in use-intra- and juxta-osseous implants. They then give a brief description of the two techniques. The advantages and disadvantages of each system are summarised, as well as the conditions required for permanent survival of a PPC.
口外植入物已用于明确的应用近20年；用于支撑颌面假体和骨锚式助听器（BAHA）。在这两种应用中，骨锚式假体都支撑经皮基台。在一定的先决条件下，正是植入物与基台之间的连接确保了永久经皮连接（PPC）。作者描述了目前使用的两种植入物类型——骨内植入物和骨旁植入物。然后他们简要介绍了这两种技术。总结了每个系统的优缺点，以及PPC永久存活所需的条件。
