摘要
[牙合]龈距离小于3 mm短冠磨牙修复难度较大,通常会采用桩核冠或髓腔固位冠修复,各有利弊。本文报道1例采用根内延伸髓腔固位冠修复2年效果良好的病例,并分析其原理、优势和缺点。
The restoration of short-crown molars with a crown-to-gum distance less than 3 mm is challenging.Typically,either a post-core crown or a pulpal chamber retention crown is used,each with its own merits and drawbacks.In this case,a modified endocrown was applied and observed for two years to analyze its principles,advantages,and disadvantages.
