In many denture articulation models, which of the following is considered the anterior determinant of occlusion?

• A. Condylar guidance
• B. Canine guidance
• C. Incisal guidance
• D. Christensen's Phenomenon

Answer: (C)

The anterior determinant of occlusion is defined by the path the mandible follows when the front teeth guide forward movement. In denture articulation, this is set by incisal guidance—the angle and overlap of the maxillary and mandibular incisors. How the incisors contact during protrusion directly controls how the posterior denture teeth disclude and contact during forward and lateral movements, shaping the functional bite. Because this anterior relationship largely determines the movement path and posterior disclusion in eccentric movements, it’s considered the primary anterior determinant. Condylar guidance governs the posterior or hinge-side movements, not the forward guidance. Canine guidance is characteristic of natural dentition and may be less reliable in complete dentures since canines are often not preserved as guiding teeth. Christensen’s Phenomenon describes a consequence of anterior guidance on posterior contacts rather than being the determinant itself.
