Occlusion for successful class IV acid-etch restorations

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.
