Palatal lift prosthesis
Palatal Lift Prosthesis[edit | edit source]
A palatal lift prosthesis is a dental device used to manage velopharyngeal dysfunction by physically lifting the soft palate. This prosthesis is particularly beneficial for individuals with velopharyngeal insufficiency due to neurological conditions, such as dysarthria or cerebral palsy.
Design and Function[edit | edit source]
The palatal lift prosthesis is designed to elevate the soft palate to improve speech by reducing nasal air escape. It consists of a framework that fits onto the teeth and a posterior extension that lifts the soft palate.
Components[edit | edit source]
The main components of a palatal lift prosthesis include:
- Framework: Typically made of metal, it attaches to the teeth to provide stability.
- Palatal Section: Covers the hard palate and extends to the soft palate.
- Pharyngeal Extension: The part that lifts the soft palate.

Retention Methods[edit | edit source]
Retention of the prosthesis can be achieved through various methods:
- Orthodontic Bands: Metal bands that encircle the teeth.
- Composite Resin: Used to secure the framework to the teeth.
Fabrication Process[edit | edit source]
The fabrication of a palatal lift prosthesis involves several steps:
1. Impression Taking: An impression of the upper dental arch is taken to create a master cast.
2. Framework Design: The metal framework is designed and fitted onto the master cast.
3. Pharyngeal Extension: The extension is crafted to lift the soft palate.
4. Final Adjustments: The prosthesis is adjusted for comfort and function.
Clinical Applications[edit | edit source]
Palatal lift prostheses are used in the management of:
- Velopharyngeal insufficiency
- Dysarthria
- Cleft palate
- Neurological disorders affecting speech
