• Definition: Anterior teeth protect posterior teeth during eccentric movements, while posterior teeth support vertical load in centric occlusion.

• Use: Full-mouth reconstructions and advanced prosthodontic cases.

• Advantage: Reduces wear and enhances long-term health of the dentition.

• Definition: Simultaneous contact of the anterior and posterior teeth on both sides of the dental arch during all mandibular movements (protrusive, lateral).

• Use: Primarily in complete dentures to enhance stability.

• Goal: Minimize tipping forces during function.

2. Monoplane Occlusion

• Definition: Teeth are arranged on a flat (monoplane) occlusal surface with no vertical overlap of anterior teeth.

• Use: For patients with poor neuromuscular control or severely resorbed ridges.

• Advantage: Reduces lateral forces on the denture.

3. Lingualized Occlusion

• Definition: Maxillary lingual cusps contact the central fossae of mandibular teeth, minimizing buccal cusp contacts.

• Use: Complete and partial dentures.

• Benefit: Combines esthetics with masticatory efficiency and denture stability.

4. Canine Guidance (Canine Protected Occlusion)

• Definition: During lateral movements, only the canines make contact, disoccluding the posterior teeth.

• Use: Common in fixed prosthodontics and natural dentition restorations.

• Goal: Protect posterior teeth from lateral forces.

5. Group Function Occlusion

• Definition: Multiple posterior teeth on the working side contact during lateral movement.

• Use: When canine guidance is not possible.

• Benefit: Distributes occlusal forces across several teeth.
