目的：分析上切牙金属桩冠根折的各种原因。方法收集我院近几年治疗的因上切牙桩冠因根折而无法保留金属桩冠及牙根的400例病例，分析根据是根桩与牙根长度关系、冠修复方式。结果上切牙金属桩冠根折与金属桩在骨内的长度有关，当长度＜牙根在牙槽骨总长度的1/2时发生牙折的几率要高于＞牙根在牙槽骨总长度的1/2时，单个桩冠根折发生率要高于联冠桩冠根折。结论金属桩核冠在修复上切牙时不仅要保证桩的长度≥临床冠的高度，还要使桩在骨内的长度大于牙根在牙槽骨总长度的1/2，同时也要考虑是单冠修复还是联冠修复。
目的：分析上切牙金屬樁冠根摺的各種原因。方法收集我院近幾年治療的因上切牙樁冠因根摺而無法保留金屬樁冠及牙根的400例病例，分析根據是根樁與牙根長度關繫、冠脩複方式。結果上切牙金屬樁冠根摺與金屬樁在骨內的長度有關，噹長度＜牙根在牙槽骨總長度的1/2時髮生牙摺的幾率要高于＞牙根在牙槽骨總長度的1/2時，單箇樁冠根摺髮生率要高于聯冠樁冠根摺。結論金屬樁覈冠在脩複上切牙時不僅要保證樁的長度≥臨床冠的高度，還要使樁在骨內的長度大于牙根在牙槽骨總長度的1/2，同時也要攷慮是單冠脩複還是聯冠脩複。

ABSTRACT:Objective a variety of reasons incisor metal post crown root fracture analysis. Methods in recent yearscollected in our hospital for treatment of upper incisor crown root fracture and 400 cases wereunable to retain metal post crown and root, according to the analysis of root pile is therelationship, and the root length and crown restoration way. Results on metal post crown root fracture length of incisors and the metal pile in the bone related, when the probability ofoccurrence of length < root fractured teeth in the total length of the alveolar bone 1/2 than > rootin the total length of the alveolar bone 1/2, single crown root fracture occurrence rate is higher than the crown crown root fracture. ensure the clinical crown length is greater than or equal tothe pile height should not only . Conclusion Metal pile nuclear crown in the restoration of maxillary incisor teeth, but also make the pile in the bone length is greater than the total length of root inthe alveolar bone 1/2, also want to consider is the single crown or linked crown.
