What are likely causes of denture clicking?

  1. Improper tooth alignment & excessive VDO

  2. Excessive VDO & poor retention

  3. Insufficient VDO & poor retention

  4. Poor base adaptation & improper tooth alignment

The correct answer is: Excessive VDO & poor retention

Denture clicking is typically caused by an excessive vertical dimension of occlusion (VDO), meaning the dentures are too tall, and poor retention, meaning they do not fit securely in the mouth. Option A is incorrect because improper tooth alignment alone is not a common cause of denture clicking. Option C is incorrect because insufficient VDO does not typically cause denture clicking. Option D is incorrect because while poor base adaptation may contribute to denture clicking, it is not listed as a likely cause, and improper tooth alignment is already included in option A.
