Occlusion for successful class IV acid-etch restorations

G E Denehy, J V Doering, D L Torney

    The Journal of Prosthetic Dentistry
    |September 1, 1980
    PubMed
    Summary

    Preventing dislodged acid-etch Class IV restorations requires checking for occlusal interferences. Dentists must examine centric, protrusive, and midprotrusive incisal contacts to ensure restoration longevity.

    Area of Science:

    • Restorative Dentistry
    • Dental Biomaterials

    Background:

    • Acid-etch Class IV restorations are susceptible to dislodgement.
    • Occlusal interferences are a primary cause of restoration failure.

    Purpose of the Study:

    • To identify critical occlusal contact regions that can compromise Class IV restoration retention.
    • To emphasize the importance of pre-restoration occlusal analysis.

    Main Methods:

    • Examination of three specific regions of incisal prematurity: centric incisal contact, protrusive incisal contact, and midprotrusive incisal contact.
    • Evaluation of occlusal interferences affecting anterior tooth restorations.

    Main Results:

    • Potential occlusal problems in the identified incisal regions can lead to premature dislodgement of Class IV restorations.
    • Addressing these interferences proactively is crucial for restoration stability.

    Conclusions:

    • Thorough occlusal analysis, focusing on incisal contacts, is essential for ensuring the long-term success of acid-etch Class IV restorations.
    • Preventive correction of occlusal interferences enhances restoration retention and durability.
