“…In the masticatory task, participants were asked to unilaterally masticate and then ingest three different types of test foods (Happy, Haihain, and Nuts) in a random order. Subjects were asked to masticate on their preferred/habitual masticatory side that was determine in a previous study ( Sano and Shiga, 2021 ; Shiga et al, 2021 ), where subjects were asked to masticate on a gummy jelly test food and report the side on which mastication appeared to be easier.…”

It still remains unclear how the suprahyoid muscles function in bolus formation during mastication. This study aimed to investigate the contributory role of the suprahyoid muscles during mastication. A total of 20 healthy young volunteers were asked to perform tongue pressure generation tasks and unilateral mastication tasks using peanuts and two different types of rice crackers. Surface electromyographic (EMG) activity of the masseter and suprahyoid muscles and mandibular kinematics were recorded. Suprahyoid activity increased with increasing tongue pressure. Masticatory duration until the first deglutition differed significantly among the different foods; the harder the food, the longer the duration. This was also the case in masseter activity per masticatory cycle. Masticatory rate and suprahyoid activity per masticatory cycle were significantly higher during soft rice cracker mastication. Masseter activity was higher on the masticatory side than on the non-masticatory side, however, there was no difference in suprahyoid activity between the sides. Suprahyoid activity and jaw gape showed significant positive correlation in the early stage on both the masticatory and non-masticatory sides. The suprahyoid muscles functioned dominantly for jaw-opening during peanut mastication, and for bolus formation, especially in the late stage during soft rice cracker mastication. Bolus formation was performed dominantly on the masticatory side during rice cracker mastication. These findings clearly demonstrate a functional role of the suprahyoid muscles during mastication of solid foods from assessments using both EMG activity and mandibular kinematic recordings.

Mastication is the first step in the process of digestion in most mammals. 1 During chewing, food is crushed by the actions of the teeth and masticatory muscles to reduce the size and mixed with saliva to moisten the food bolus. Although basic digestive motor actions such as chewing and swallowing are triggered and controlled by a central pattern generator in the brain stem, 2,3 bolus information in terms of its size, temperature, texture, or moisture gradually changes, and motor patterns can adapt to these characteristics. In this meaning, there are several factors determining the masticatory movement pattern.

Key Clinical MessageThe treatment method of placing a small number of implants in the mandible as a removable implant‐supported overdenture (IOD) enables implant placement and denture stability, even in cases with severe residual ridge resorption. In this case report, a new implant placement technique was performed using a three‐dimensionally (3D)‐printed duplicate denture fabricated by a 3D printer, resulting in the restoration of masticatory function through IOD.
