Toothwear- (Intro+Abrasion)

Question 1

What problems may be faced with tooth wear cases?

Answer 1

1) No intercuspal space for restoration to be placed.
2) Lack of tooth tissue for build ups or crown preps.
3) Increased gingival display (due to dento-alveolar compensation)
4) Pulpal problems
5) Changes to patient’s OVD

Question 2

What is dento-alveolar compensation?

Answer 2

It is the continued eruption of the teeth in response to wear. It leads to a change in the position of the gingival margin.

Tooth wear caused by contact with extraneous (foreign) objects.
