“…Mastication is defined as the process of chewing food before swallowing and digestion [ 15 ]. It differs from masticatory force, which is defined as the maximum biting force on occlusal contacts recorded with strain gauge transducers, piezoresistive transducers, piezoelectric transducers, optical fiber transducers, and pressure-sensitive films [ 16 ]. The mastication process consists of two separate processes: the selection of the food placed between the teeth, followed by the breakdown of the particles (breakage) [ 17 ].…”

Background: Mini dental implant (MDI) overdenture rehabilitation for the edentulous maxilla is a valuable, less invasive and affordable treatment alternative for complete removable dentures (CRD). However, comparative quantification of masticatory performance in different oral conditions are scarce. Purpose: This study compares objective masticatory performance of dentate groups, maxillary CRD and MDI overdentures and subjective masticatory performance in maxillary CRD and MDI overdentures. Materials and Methods: Four groups were defined, age 20+ dentate dental students (DS), age 50+ complete dentate subjects (DP), age 50+ maxillary CRD or MDI overdentures/dentate mandible. Objective masticatory performance was evaluated by measuring circular Variance of Hue (VOH) or the mixture degree of two-color chewing gum (Hue-check View Gum® Test). Additionally, subjective masticatory comparison was investigated in the CRD and MDI groups, with a visual analogue scale (VAS) for different food consistencies and the Oral Health Related Quality of Life (OHRQL) OHIP-14 questionnaire. Results: The mean VOH was 0.11 (SD 0.50, range 0.05–0.27) for the dentate dental 20+ students, 0.13 (SD 0.08, range 0.03–0.31) for the 50+ dentate group (p = 0.774), 0.41 (SD 0.41, range 0.14–0.76) for the CRD group and 0.39 (SD 0.18, range 0.07–0.76) for the MDI group (p = 0.725). Based on the VAS scores, no improvement was found between the CRD and the MDI overdenture group (p > 0.050). The mean OHIP-14 total score was 12.10 (SD 15.87, range 0–56) for CRD, while the MDI group (p = 0.039) saw a significant improvement to 2.85 (SD 2.85, range 0–15). Conclusion: Comparable results in objective masticatory performance were registered in dentate 20+ and 50+ subjects with a remarkable inferior outcome for the CRD and MDI group. Compared to CRD, MDI overdentures revealed no substantial improvement in subjective and objective masticatory performance. However, for MDI a significant increase in OHRQL was apparent.

“…Moreover, for the maximal incisal region force recording, “pain in teeth” might be the major limiting factor for expressing MBF [ 11 ], and since the surface of the recording devices is usually made with hard materials, an uncomfortable and hazardous feeling may be perceived by many subjects [ 4 ]. Placement of the sensor relative to the force application point may also affect measured MBF due to the mechanical leverage caused by the metal plate of the bite fork used in the strain gauge transducer [ 21 , 22 ]. Piezoresistive transducer devices, consisting of a crystal silicone material that changes resistivity with the applied force, have been proven to be highly sensitive, thin, lightweight, and cheap but less accurate than strain gauge devices [ 21 ].…”

“…Piezoelectric transducers use the piezoelectric effect of a material to convert the pressure into an electric signal. These devices are generally very thin (0.1 mm) and can be used to record MBF in subjects with minimal jaw opening, but they are limited by a narrow range and low sensitivity and flexibility of the sensor [ 21 ]. Pressure-sensitive devices consist of a chamber filled with fluid or air and a pressure gauge, which measures chamber pressure.…”

Assessing maximum voluntary bite force is important to characterize the functional state of the masticatory system. Due to several factors affecting the estimation of the maximum bite force, a unique solution combining desirable features such as reliability, accuracy, precision, usability, and comfort is not available. The aim of the present study was to develop a low-cost bite force measurement device allowing for subject-specific customization, comfortable bite force expression, and reliable force estimation over time. The device was realized using an inexpensive load cell, two 3D printed ergonomic forks hosting reusable subject-specific silicone molds, a read-out system based on a low-cost microcontroller, and a wireless link to a personal computer. A simple model was used to estimate bite force taking into account individual morphology and device placement in the mouth. Measurement reliability, accuracy, and precision were assessed on a calibration dataset. A validation procedure on healthy participants was performed to assess the repeatability of the measurements over multiple repetitions and sessions. A 2 % precision and 2 % accuracy were achieved on measurements of forces in the physiological range of adult bite forces. Multiple recordings on healthy participants demonstrated good repeatability (coefficient of variation 11 %) with no significant effect of repetition and session. The novel device provides an affordable and reliable solution for assessing maximum bite force that can be easily used to perform clinical evaluations in single sessions or in longitudinal studies.

“…Nonetheless limitations of the current bite force devices are still present in that the T Scan system cannot measure the bite force accurately, meanwhile the Prescale system is unable to function continuously. The other various measurement devices are mostly highlighted in experimental studies and warranted further clinical validation [ 11 ]. Meanwhile, electromyography has been reported in recently published research as a possible technique for bite force registration [ 12 ].…”

Bite force measurement is an important parameter when checking the function and integrity of the masticatory system, whereas it is currently very difficult to measure bite force during functional movement. Hence, the purpose of this study is to explore the potential technique and device for the measurement and intervention of the continuous bite forces on functional and dynamic occlusal condition. A portable biosensor by sandwich technique was designed, and the validity, reliability, and sensitivity were determined by mechanical pressure loading tests; meanwhile, the pressure signal is acquired by, and transmitted to, voltage changes by the electrical measurements of the sensors. The result is that, when the mechanical stress detection device is thicker than 3.5 mm, it shows relatively ideal mechanical properties; however, when the thickness is less than 3.0 mm, there is a risk of cracking. Mechanical stress changing and voltage variation had a regularity and positive relationship in this study. The mechanical stress-measuring device made by medical and industrial cross has a good application prospect for the measurement of bite force during function.
