“…In addition, our results indicate a significant (25.6%) difference in BF between the dominant-and non-dominant side of CCD wearers. Even more pronounced differences were recently reported by Shala et al (22), who found a BF in CCD users that was 80% lower in the non-dominant side. These authors attributed this difference to the individual preference for unilateral chewing, which contributes to muscle tonicity improvements and consequently results in greater BF (22).…”

Evaluation of Bite Force and Masticatory Performance: Complete Denture vs Mandibular Overdenture Users

et al. 2020

This cross-sectional observational study with 24 patients evaluated differences in bite force (BF) and masticatory performance (MP) between conventional complete denture (CCD) and implant mandibular overdenture (IMO) users and the correlation between these variables. The BF test was performed bilaterally with an occlusal force device. During the MP test, patients were asked to chew Optocal particles for 40 cycles. The Shapiro Wilk test was employed to verify the normality of the data, the student t test to identify differences between groups, and Pearson’s correlation to investigate interrelationships between variables. A multiple linear regression was subsequently performed via the stepwise method. P values ≤0.05 were considered statistically significant. Unlike IMO users, CCD users presented a significant difference (25.6%) in BF between the dominant and non-dominant chewing side (p=0.04). IMO users presented significantly higher BF (p=0.01) without presenting a dominant side (p=0.38), and also performed significantly better for the following MP parameters: MPX50 values decreased by 27.25% in IMO users (p=0.01), MPB decreased by 48.38% (p=0.01), and ME 5.6 decreased by 53.25% (p=0.02), while ME2.8 increased by 151.57% (p=0.01). The BF and MPX50 in the IMO wearers group were negatively correlated (-0.57; p=0.05); this correlation coefficient was the only parameter included in the multivariate regression model. IMO users have higher BF and better masticatory performance than CCD users, especially in terms of chewed particles size reduction. MP is correlated with a higher BF in IMO users through better particle trituration.

“…At the same time, studies show that the maximum force value in these patients varies according to the moment of recording relative to the moment of complete denture's application. Thus, even if this force has low initial value, some studies show a considerable increase after a period of 6 months [17], while other after a period of 7 weeks [18] from the application of the complete denture, as a result of patients' adaptation to the prostheses [18]. However, the value of the masticatory force remains lower than in dental subjects, by 20%-40% [17].…”

“…Okamoto, in 2012, finds an average value of 412.61N in complete denture patients [16]. Studies show that, from the point of view of localization, maximal masticatory force is developed in the first molar area [17][18], and it is also considered that 80% of the total masticatory force is distributed here. Taking into account the results of these researches, in our study the forces were applied in the first molar area, one of the purposes being to determine if the acrylic resin from which the complete denture is made can resist to the usual maximum forces exerted during mastication.…”

The aim of our study was to evaluate fracture resistance of the PMMA complete dentures and to make a comparison between the classic acrylic maxillary complete dentures and the metal-reinforced ones, in terms of fracture resistance during function and to compare the fracture pattern of the two groups of complete dentures. We used maxillary complete dentures made of heat-processed acrylate, 5 exclusively and 5 in which a metal-cast net in the form of a mesh was inserted after being casted, worn by patients for a period of 5 years. A bilateral progressive force was applied to the PM2-M1 area until the samples failed, recording the force value at which the first change occurred. A Universal Loading Machine was used. The results were analyzed using the ANOVA method. For the classic acrylic complete dentures group, the minimum fracture force value was 1060 N, the maximum fracture force value being 2443 N. For the reinforced complete dentures group, the minimum fracture force value was 3320 N, the maximum value being 3760 N. Statistical analysis of data using the ANOVA shows that the results are statistically relevant, with a p value of 0.000137 (p[0,05). All the dentures from the classic acrylic complete dentures group fractured presenting two or more fracture lines, most of them involving also fractures on the acrylic teeth and breaking into multiple pieces, while all the dentures from the reinforced complete dentures group fractured presenting one or two fracture lines, most of them without detachable fragments and involving also fractures on the acrylic teeth.

“…Naïve mice showed apparently increased bite force during repeated weekly testing, which may be related to the habituation or adaptation to the test as training can improve biting efficiency [10,12]. Similarly, the maximum bite force in patients with complete dentures increases during repeated testing [55]; and repeated exercises of the masticatory muscles can reduce muscle pain and fatigue [56]. In patients of first bite syndrome, pain triggered by the first bite of a meal improves in the subsequent bites [57,58].…”

Introduction: Pain-related behavior secondary to masticatory function can be assessed with the rodent bite force model. A reduction of the bite force has been shown to be related to pain associated with the masseter muscle and jaw activity, while an increase in bite force suggests improvement of muscle function and less pain. To evaluate the usefulness of the bite force measure in studying long-lasting orofacial pain we analyzed biting parameters during prolonged myofascial pain induced by ligation injury of the masseter muscle tendon (TL) in mice. Methods: C57BI/6 mice were habituated to bite at a pair of aluminum plates attached to a force displacement transducer. The transduced voltage signals were amplified and converted to force through calibration with a standard weight set. Voluntary biting behavior was recorded for 100 seconds/session and those with bite forces ≥ 980 mN were analyzed. Nociception was also verified with von Frey, conditioned place avoidance (CPA) tests and mouse grimace scale. Persistent orofacial pain was induced with unilateral ligation of one tendon of the masseter muscle (TL). Results: To reduce interference of random bites of smaller forces, the top 5 or 15 bite forces (BF5/15) were chosen as a measure of masticatory function and related to pain behavior. Both male and female mice exhibited similar BF5/15. For the first nascent test of all mice, mean bite force was significantly and positively correlated with the body weight. However, this correlation was less clear in the latter tests (2-8 w). TL induced a reduction of BF5/15 that peaked at 1 w and returned to the baseline within 3 w. The von Frey and CPA tests indicated that mechanical
