Study Notes
Speech Production
- When speaking, the soft palate is raised to prevent air from escaping into the nasal cavity.
- This directs the entire air stream through the mouth to produce specific sounds.
Types of Oral Sounds
- Vowel sounds are produced, including: • A • E • I • O • U
- Oral consonants are produced, including: • Stopped consonants • Fricative consonants
Essentials of Maxillofacial Prosthetic Appliance
- Must be easily seated in place comfortably and securely retained as much as possible
- Must be durable and easy to clean
- Must be made of material that can be easily adjusted and altered if needed
- Must be made of inert and biocompatible material
