Which of the following is not desirable in complete denture occlusion
1 Minimum occlusal contact areas for reduced pressure in comminuting food
2 Functional lever balance by favorable tooth to ridge crest position
3 Balanced occlusal contacts bilaterally for all eccentric movements
4 Anterior incisal contacts during all posterior masticatory functions and para
function
Prosthodontics
Answer: 4
Explanation: Anterior incisal contacts during posterior
masticatory functions are not desirable because they can lead to instability and
improper function of the complete denture. Ideally, posterior teeth should
provide the primary occlusal contacts during chewing, while anterior teeth
should not interfere with these functions. This helps maintain a balanced
occlusion and prevents excessive wear or damage to the denture.
