在牙齒拔除後齒槽脊會逐漸吸收且外型上會有所改變。這些改變在臨床上是有意義的，因為會造成日後傳統贋復假牙或植體支持性假牙製作上的困難。因此減少拔牙後齒槽脊的吸收，幫助日後製作的假牙滿足功能和美觀上的需求是臨床上一個重要的課題。本文將就拔牙窩洞癒合的過程和保存齒槽脊的方式做一探討。

Alveolar ridge will gradually decrease in volume and change morphologically after tooth extraction. The phenomena in clinical practice are meaningful. It will affect the future clinical procedure difficulties, including conventional prosthodontic rehabilitation or implant-supported prosthesis. Thus it is an important topic of minimizing the degree of ridge resorption after tooth extraction to meet the future appearance and functional needs of denture production. This article will explore the healing pattern of extraction socket and the clinical application of socket preservation.
