Palatal lift prosthesis

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

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

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

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

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.
