摘要

在骨整合之後的牙科植體後支台的選擇是影響牙科植體復形的重要因素，然而到目前為止，牙科植體後支台的選擇方針仍尚未明確。
目前市面上有許多不同的牙科支台，用於黏用式或螺絲固定式復形物，相對於這些復形物，牙科植體支台的選擇，就必須考慮到功能性表現性，因此，客製式的支台，包括UCLA支台和客製式的黏著式支台，是最容易達到這些考慮的，事實上，客製式支台是最能夠讓牙科植體復形達到表現的工具。
在這篇文章中，有一些選擇支台的原則會被提出以供牙醫師參考，同時也討論了一些不適當支台選擇的狀況，以供植體復形的選擇考量。

Implant abutment selection after actual osseointegration of the implant is an important factor in influencing the ultimate outcome of the implant restoration. However, the guidelines for abutment selection are not clear in current implant dentistry.
There are many different abutments for both screw-retained and cement-retained restorations. Regardless of which abutment is selected, functional and esthetic considerations are the main factors for clinical application. Therefore, customized abutments, which include both screw-retained UCLA abutments and cement-retained custom abutments, are frequently the option of choice to meet these goals. These customized abutments are more user friendly for achieving predictable esthetics with implant supported restorations.
In this article, guidelines for implant abutment selection will be proposed to help dentists make appropriate decisions. The complications that may occur as a result of inappropriate abutment selection will be discussed to provide a frame of reference for decision making in clinical implant therapy.
