Overdenture Exam Latest 2025 with Complete
Answers!!
What are the other names for an overdenture? - ANSWER Overlay denture, telescopic
denture, tooth supported denture, hybrid denture
What is an overdenture? - ANSWER A removable partial denture or complete denture
that covers and rests on one or more *remaining natural teeth,*the *roots* of the
natural teeth or *dental implants*
What does extraction lead to? - ANSWER -Continuous ridge resorption overtime
-Loss of PDL receptors
What does maintaining teeth as part of an overdenture provide? - ANSWER Maintains
teeth as part of the residual ridge
-Provides support, stability and retention
-Decrease the rate of alveolar bone resorption
-Retain the proprioception - aids in the patient being able to seat the denture
Results of the Crum et al study - ANSWER Complete denture group had 8 times more
ridge resorption than the mandibular over denture group
What are the advantages of an over denture? - ANSWER 1. Ridge preservation
2. Physiological advantage by maintaining proprioception
3. Definitive vertical stop for denture base
4. Stability, retention and support are increased
5. Less trauma to supporting structure - some of the forces are places on the teeth
6. Fewer post insertion problems compared to conventional denture
, 7. Improved masticatory performance
What are the disadvantages of an over denture? - ANSWER 1. Caries susceptibility
2. Perio disease around abutment teeth
3. *Limited path of insertion due to bony undercuts*
4. Reduced inter-occlusal distance - 2nd biggest disadvantage
5. Meticulous oral hygiene
6. Time consuming
7. More expensive due to abutment prep
Does a younger or an older patient respond better to an overdenture? - ANSWER
younger
Should a patient with a lot of remaining natural teeth or little remaining natural teeth? -
ANSWER little remaining teeth
Is it better to have a single overdenture opposed by another denture or natural teeth? -
ANSWER natural teeth
What are the indications for an overdenture? - ANSWER 1. Patients with few natural
remaining teeth
2. Younger patients
3. Single denture opposed by natural teeth
4. Poor prognosis for conventional complete denture - Class IV ridge resorption
5. Patient with acquired or congenital defect
6. Severe attrition and loss of vertical dimension
