. Specifically, gumi is chewed until swallowable, swallowed, observed by the nasopharyngeal fiber, whether there is no choking at swallowing, presence of residual gummy, smooth flow into the pharynx

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: Those who are 20 years or older who have no abnormality in feeding / swallowing in patients after mandibular bone reconstruction. Those who are 20 years old or older who have no history and no abnormality in eating or swallowing.

Exclusion criteria

Exclusion criteria: Underage, those with chew swallowing disorder, and those with allergies to gummies

Design outcomes

Primary

Measure	Time frame
Evaluation of chewing function: Gumi is chewed 30 times freely and spit out. Evaluate the grinding degree of gummies on the scale table. The occlusal ability is measured by using an occlusal capability measuring instrument to measure occlusal pressure. Evaluation of swallowing function: As for evaluation, chewing swallowing evaluation is performed with reference to the Japan Feeding and Swallowing Rehabilitation Association "Revised Procedure for Swallowing Endoscopy 2012 Revised". Specifically, gumi is chewed until swallowable, swallowed, observed by the nasopharyngeal fiber, whether there is no choking at swallowing, presence of residual gummy, smooth flow into the pharynx Evaluate points. The observation result is made into a database, examination of the size, form and color tone suitable for evaluation of the patient after the mandibular bone reconstruction, and preparation of adjusted gummies. Using this, masticatory function evaluation and swallowing function evaluation are performed again for patients after mandibular bone reconstruction. In addition, based on the data obtained by the mastication function and the swallowing function, the functional evaluation method is considered as an integrated evaluation of chewing and swallowing function.	—
