Crown Lengthening – KLIDC

Crown Lengthening

English

When a tooth is fractured deep into the gum line or has cavities that extend too far into the gum, making it difficult to repair, or when there is insufficient tooth structure exposed above the gumline to support the creation of a dental crown or orthodontic appliance. In such cases, crown lengthening involves removing excess gum tissue and reshaping or removing some of the alveolar bone to expose the damaged tooth structure above the gumline, making it suitable for cavity restoration or appliance placement.

In situations where some patients show excessive gum display, especially in the anterior region of the upper jaw, resulting in teeth appearing with very short crowns or uneven gum levels, crown lengthening can be used to increase the crown length of teeth, ensuring uniformity in crown length and gum positioning between adjacent teeth.

当牙齿产⽣断裂到牙龈内部户或是牙齿的蛀洞太深延长到牙龈⾥⾯时,难以填补或是剩下的齿 质结构露出牙龈外的部分太少无法制成牙套,可以考虑使⽤牙冠增长术的⽅式修掉多余的部分牙龈,磨去部分齿槽骨,使的缺角牙齿露在牙龈的外⾯,有利于蛀洞的填补或是牙套上的制作。

某些患者于微笑时上颚的前牙区域会看见许多的牙龈,在牙冠上看起来非常短,或是牙龈的所 在位置呼⾼呼低,局部的牙冠长度不⼀致,可以利⽤此⼿术⽅式来增长牙冠的长度,让左右相 邻的牙齿上牙冠的长度及牙龈的位置协调成⼀致。
