摘要

奶瓶性齲齒仍是台灣兒童常見的牙科疾病，為了能夠保留乳牙，牙醫師利用了諸多方法來幫助製作補綴物。本文報告幾種製作上顎乳前牙牙根釘柱的材料、其製作的步驟以及不同材料的比較。統整結果：利用香菇狀的根管製備，再以複合樹脂作為牙根釘柱的製作材料，不僅價格便宜，製作簡單且省時，目前是最常使用的製作方式。而鎳鉻鑄造牙釘與矯正金屬線因為是金屬材料，有美觀上的缺點，後者的製作更是十分耗時。近年慢慢發展的玻璃纖維、聚乙烯纖維等材料，則仍有研究空間。至於影響上顎乳前牙牙根釘柱穩固性的因素，包括：剩餘齒質的量、根管封填材料、酸蝕方式，以及黏著劑的選擇等。

Rampant caries is one of the most common dental diseases in Taiwan. Dentists make every effort to restore severely destroyed primary anterior teeth for preserving the teeth. This article reviews the materials of short posts, the fabricating methods, and the comparison of the posts. The results show that composite resin as a material for making short post is inexpensive and time-saving, therefore it is the most acceptable material until now. The major disadvantage of Nickel-Chromiun cast posts and orthodontic wires is poor esthetics, and the fabrication of the latter material is time-consuming. Glass fiber and polyethylene ribbon fiber is still being researched. The factors affecting the retention of short posts include the remaining tooth structure, endodontic filling materials, etching, and adhesives.
