Adjusting occlusion in ceramic restorations is a critical step to ensure the longevity and functionality of the restoration. Proper occlusion prevents issues such as uneven wear, discomfort, and damage to the surrounding teeth. This article provides a step-by-step guide for dental professionals to achieve optimal occlusion in ceramic restorations.
Preparation Before Adjustment
Before beginning occlusal adjustments, ensure the restoration is properly seated and the patient is comfortable. Verify that the restoration fits well and is cemented securely. Use articulating paper to identify high spots and areas of contact.
Initial Check of Occlusion
Have the patient bite down naturally. Use articulating paper to mark contact points. Identify any areas where the restoration contacts prematurely or excessively. These spots need adjustment to achieve even contact.
Adjusting High Spots
Use a fine diamond bur or abrasive stone to carefully reduce the high spots. Work incrementally, checking frequently with articulating paper. Ensure that the adjustment is smooth and that the contact points are evenly distributed.
Refining the Occlusion
After initial adjustments, have the patient occlude again. Reapply articulating paper to confirm that contacts are now evenly distributed. Continue refining as needed to eliminate any premature contacts or interferences.
Checking Dynamic Occlusion
Assess the patient’s occlusion during lateral and protrusive movements. Use articulating paper or shim stock to identify any interferences. Adjust the restoration to allow smooth, functional movements without catching or blocking.
Final Verification and Polishing
Once the occlusion is properly adjusted, verify with multiple biting cycles. Confirm that the contact points are ideal and that the patient experiences no discomfort. Polish the restoration to ensure a smooth, natural surface that resists plaque accumulation.
Proper occlusal adjustment in ceramic restorations enhances their durability and the patient’s comfort. Regular follow-up appointments are recommended to monitor occlusion and make further adjustments if necessary.
