Restorative Crown Lengthening

Tooth structures can become compromised due to decay, fractures, or functional wear. In some cases, the cumulative damages result in inadequate tooth structure to restore a tooth adequately and predictably (such as with a crown or fillings). A restorative crown-lengthening procedure can be performed to expose more tooth structure for the required restoration.

Figure B: The treatment plan involved fabricating new crowns. In order to remove all the decay successfully, to prevent soft tissue irritation, and to allow better crown retention, the clinical crowns were lengthened.
