The correlation between two occlusal analyzers for the measurement of bite force

Abstract

Background Occlusal force represents masticatory function. Using quantifiable occlusal indicators provides a more objective occlusal force evaluation. In the recent dental practice, digital methods such as the Dental Prescale II (DP2, GC Corp., Tokyo, Japan) and T-scan (T-Scan III v8; Tekscan Inc.) are commonly used in clinics to evaluate treatment outcomes. The T-scan provides the relative bite force (%) compared to the maximal bite force on individual teeth or the unilateral arch. The DP2 can quantify occlusal force, measured in newtons (N), on the half arch or the overall bite, but it is difficult to identify the bite force on an individual tooth. It is difficult to select a device that fulfils all the requirements to record occlusal force. This study aimed to investigate the association between the bite measured by the DPS2 and T-scan to determine whether the measured bite force is comparable through calculation. Methods A total of 80 healthy adults, including 41 women and 39 men with a mean age of 38.2, were requested to bite pressure sensitive film sheets ten minutes apart. Linear regression analysis was used to estimate the measured bite force by the DP2 and T-scan. Results There was a significant positive correlation between the occlusal force measured by the DP2 and T-scan (P < 0.01) when intercept was equal to zero as confounders were adjused. These results provided the comparability of the measured occlusal forces determined by the DP2 and T-scan. Conclusion The estimated bite force determined by DP2 and T-Scan is convertible using the linear equation from this study to increase the value for clinical applications. The estimated bite force from the two quantifiable occlusal indicators are comparable. The two commercially available quantifiable occlusal indicators can be fully adapted to all clinical requirements according to this result.

Construction of a novel digital method for quantitative analysis of occlusal contact and force

“…However, oral appliances increase the inconvenience of occlusion collection. In addition, due to the limitations of the T-scan [ 37 ], it can only display the relative value of the force and cannot obtain the absolute magnitude of the occlusal force, let alone the decomposition of the occlusal force. The study by Hattori et al proposed a method to set the occlusal force value and direction and initially constructed a 3D occlusal force analysis system.…”

Improvements in Maximum Bite Force with Gum-Chewing Training in Older Adults: A Randomized Controlled Trial

“…In addition, in this study, Dental Prescale II was used for the maximum bite force measurement. The reliability of Dental Prescale II has been established in previous studies [33][34][35]. Wang et al [33] compared the reliability of the occlusion assessment using three different occlusion measurement tools articulating paper, Dental Prescale II, and a virtual occlusal construction method, with that using a silicone bite registration material and reported that all three, including Dental Prescale II, showed a good reliability in clinical applications.…”

In addition, Dental Prescale II showed significant correlations with the other bite-force-measuring devices, Dental Prescale (the previous version of the Dental Prescale II) and T-Scan, with a high reliability [34,35]. Therefore, Dental Prescale II is considered to be a tool that can be used to quickly and simultaneously evaluate both occlusal bite force and occlusal contact area.…”

Main Methodological Aspects of Determining the Chewing Efficiency

“…To date, there are known force criteria for molar and incisor bites in humans, [28] but there is insufficient data on determining bite force for all types ОГЛЯДИ ЛІТЕРАТУРИ / LITERATURE REVIEWS of teeth or age-related features of bite force potential. Various bite force models can be used to predict the bite force at different points of the bite in the adult population, such as the limited leverage model [29].…”
