Konuskrone之基本理論及製作
The Basic Principle and Fabrication of Konuskrone
摘要
近幾年來Konuskrone有被廣泛使用於局部活動義齒及可撤式冠橋義齒的設計之趨勢。其製作理論係源自「強支持」的觀念，取得強支持除考慮支台齒的條件外,對於缺牙區齒槽(山脊)的條件及咬合的條件也要一併考慮。一般只要支台齒牙周組織健全,多數齒或游離端缺損,缺牙區粘膜壓縮性小，支台齒齒輪方向不平行時,都是製作的適應症,但少數殘存齒只剩兩支而分怖狀況呈犬齒以後對稱型或對角線型時則屬於禁忌症。成功的Konuskrone在於支台齒的修形、暫時補綴物及內冠 的製作、試戴、缺牙區齒槽(山脊)的印模、調節性咬合器的用法、外冠的完成、義齒床的盒埋及填充、粘合等要完全理解及熟練才行 。本文以各學者及筆者自己之經驗,分別提出各作法之優缺點及 異問處,予以歸納及比較,以提供牙醫師及技工士之參考。

Recently, Konuskrone has the trend to be used in removable partial denture and removable crown and bridge. The principle of its fabrication is based on the concept of ”rigid support”﹒In order to establish the rigid support, the conditions of edentulous alveolar ridge and occlusion should also beconsidered except abutment teeth‘In general, healthy Periodontal tissue, multiple missing teeth or distal free-end, Iess compression of dentme supporting tissue and unparallel long axis of abutment teeth are the indications for Konuskrone. The symmetric or diagonal distributed residual teeth posterior to canines is the contraindication. To satisfy Konuskronc, it is necessary to fairly understand and have excellent techniques about the preparation of abutment teeth, the fabrications of interim restoration and inner crown, try in, the impression of edentulous ridge、the usage of adjustable articula tor, the completion of outer crown, the flasking and packing of denture base, and cementation.This paper summarizes and compares the advantages and disadvantages to the construction of Konuskrone of different techniques and provides as a reference fot clinicians and technicians.
