Palatal obturator
Palatal Obturator
The Palatal Obturator (pronunciation: puh-LAY-tuhl ob-too-ray-tor) is a prosthesis that completely or partially occludes an opening in the roof of the mouth. These openings may be due to surgical removal of a part of the palate, or due to congenital defects such as a cleft palate.
Etymology
The term "Palatal Obturator" is derived from the Latin words "palatum" meaning roof of the mouth, and "obturare" meaning to close or shut off.
Function
The primary function of a palatal obturator is to aid in speech and swallowing. It helps to close off the nasal passages during the production of oral sounds, and prevents food and liquid from entering the nasal cavity during swallowing.
Types
There are two main types of palatal obturators:
- Temporary Obturator: This is usually placed immediately after surgery to allow for healing. It is replaced with a definitive obturator once healing is complete.
- Definitive Obturator: This is a more permanent solution, designed to fit the patient's mouth perfectly. It is usually made of a more durable material than the temporary obturator.
