Full mouth reconstructions are complex dental procedures aimed at restoring the function, esthetics, and health of a patient's dentition. One of the critical aspects of these procedures is achieving proper occlusion, which ensures that the upper and lower teeth fit together correctly during biting and chewing. This article presents several case examples demonstrating effective strategies for improving occlusion in full mouth reconstructions.

Case Example 1: Addressing Malocclusion with Digital Planning

A 45-year-old patient presented with severe malocclusion, including deep bite and crossbite. Digital smile design and CBCT imaging allowed precise planning of the occlusal adjustments. Using CAD/CAM technology, restorations were fabricated to establish proper anterior guidance and posterior contacts. The outcome was a harmonious bite and improved function.

Case Example 2: Managing Vertical Dimension Loss

An elderly patient exhibited significant vertical dimension loss due to wear and attrition. After evaluating the occlusion, a phased approach was adopted. Initially, a provisional increase in vertical dimension was tested using temporary restorations. Once confirmed, definitive restorations restored the vertical height, resulting in improved esthetics and function.

Case Example 3: Correcting Functional Imbalances

This case involved a patient with uneven occlusal contacts causing temporomandibular joint (TMJ) discomfort. A comprehensive occlusal analysis identified the problematic contacts. Selective grinding and the placement of occlusal splints helped balance the bite. Final restorations were adjusted to maintain the corrected occlusion, alleviating TMJ symptoms.

Key Strategies for Improving Occlusion

  • Use digital planning tools for precise diagnosis and treatment design.
  • Evaluate vertical dimension and make incremental adjustments.
  • Perform selective occlusal adjustments to balance contacts.
  • Employ provisional restorations to test changes before finalizing.
  • Address functional and esthetic concerns simultaneously.

These case examples highlight the importance of a systematic approach to occlusion in full mouth reconstructions. By integrating advanced technology and careful planning, clinicians can achieve predictable and successful outcomes for their patients.
