| Outline of Final Research Achievements |
Lip closing functions is thought to be very important factor in maintaining a negative pressure in the oral cavity when performing a normal swallowing, and also to be affecting articulation and arch form of the teeth. In this study, we aimed to reveal the relationship between lip closing functions, and the masticatory ability and articulatory function of the cleft lip and palate patients. In order to achieve this purpose, a balloon type lip pressure measuring device and lip movement analyzing system were newly developed. In addition, optimization of the myoelectric measurement conditions specific to the lip closing function was performed. Furthermore, performing both the masticatory ability assessment by the chewing gum method and articulation assessment by speech therapist, it was possible to clarify the characteristics of the functional problems recognized in common by the entire cleft lip and palate patients.
