[Pathologic abrasion].

    Summary

    Pathologic dental abrasion, excessive loss of tooth structure, can lead to severe tooth wear. Despite its severity, it is often well-tolerated, with simple treatments recommended over complex ones for long-term success.

    Area of Science:

    • Dentistry
    • Dental Biomaterials

    Context:

    • Pathologic abrasion is defined as excessive loss of hard dental substance, potentially leading to complete anatomic crown removal.
    • This condition, while severe, is often well-tolerated over time.
    • Commonly observed types include helicoidal, ad palatum, horizontal, and keylock abrasion patterns.

    Purpose:

    • To define and categorize pathologic abrasion of dental hard tissues.
    • To explore the etiology of excessive dental abrasion, primarily bruxism and diet.
    • To discuss the management of vertical dimension of occlusion (DVO) in patients with extreme abrasion.

    Summary:

    • Excessive dental abrasion, often caused by bruxism, results in significant loss of tooth structure.
    • Despite severe tooth wear, the vertical dimension of occlusion (DVO) typically remains stable due to compensatory dental eruption.
    • Prosthetic therapy should avoid altering the DVO in cases of extreme abrasion; simple solutions are preferred for long-term outcomes.

    Impact:

    • Highlights the importance of recognizing and managing severe dental abrasion.
    • Suggests conservative treatment approaches for patients with extreme tooth wear.
    • Emphasizes the adaptive capacity of the stomatognathic system in response to progressive abrasion.
