Study Notes
Objectives of Occlusion in Complete Dentures
- Preserves remaining oral tissues to maintain overall oral health.
- Promotes efficient mastication for better food processing.
- Enhances stability, retention, and support of the denture for comfort and function.
- Improves phonetics and aesthetics, aiding in verbal communication and facial appearance.
Types of Occlusion
- Balance Occlusion
- Lingualized Occlusion
- Monoplane Occlusion
Balance Occlusion
- Defined as stable simultaneous contact of upper and lower teeth in a centric relation position.
- Allows for smooth bilateral gliding movements from centric position into eccentric ones during normal jaw function.
- Involves contact between buccal and lingual cusps of maxillary and mandibular posterior teeth.
- The occlusal surface creates an imaginary anatomical relationship with the cranium, touching incisal edges of incisors and tips of posterior teeth surfaces.
- Key factors include compensating curves and inclinations of cusps on the occlusal surfaces.
- Maxillary palatal cusp tips should align with the central fossa of mandibular teeth for optimal balance.
- Flat cusp inclines on mandibular teeth reduce lateral forces and tooth displacement during function.
Indications for Balance Occlusion
- High aesthetic demands requiring a natural appearance.
- Weak masticatory muscles needing additional support.
- Presence of displaceable supporting tissues necessitating stable occlusion.
- Severe resorption of alveolar bone affecting denture positioning.
- Discrepancies in jaw sizes that require careful occlusal adjustments.
