Association of bite force with ageing and occlusal support in older adults

Maximal bite force and its association with temporomandibular disorders

“…In a previous study (14), mean MBF values of TMD subjects in molar and incisal regions were reported as significantly higher for male than for female, suggesting that a separate evaluation of the genders would be advisable in future studies involving bite force assessments, which corroborates the results of the present study. Furthermore, bite force was significantly stronger in healthy male than in female (18). The present study also found stronger bite force for males than for females, both in healthy and TMD subjects, echoing the findings from previous studies.…”

“…The association between the presence of TMD and reduced MBF is contradictory in the literature and may be dependent on the severity of the TMD in the given sample (14)(15)(16)(17). Our results agree with those of previous studies (2,18,19), where no association between TMD and bite force was observed, and neither subjective symptoms nor clinical signs of TMD correlated significantly with MBF values (14).…”

“…The present study, however, found significant correlation in TMD subjects for weight in female and weight and height in male subjects and no correlation for age. Bite force may be significantly associated with gender and age independently of a low bite force, and male subjects should exhibit higher MBF (18). No significant associations between MBF and body mass were found (15), demonstrating that signs and symptoms of TMD, unlike body mass, are independently associated with MBF.…”

Age-dependent Three-dimensional Microcomputed Tomography Analysis of the Human Midpalatal Suture*

“…Akzeptiert man die Hypothese der suturalen Dämpfungsfunktion im Wechselspiel zur Kaufunktion, kann auch die zunächst nicht erklärbare Sonderstellung der mittleren Altersgruppe mit signifikant erhöhter Knochendichte erklärt werden. Aktuelle Studien konnten mit zunehmendem Alter aufgrund von Zahnverlust und zunehmenden Allgemeinerkrankungen einen Abfall der mechanischen Belastung der Maxilla registrieren [2,24]. Geringere funktionelle Belastungen durch Qualität der Nahrung, reduzierten Zahnstatus und Allgemeinzustand könnten die in der aktuellen Literatur beschriebenen erfolgreichen konservativen Erweiterungen der Maxilla bei Erwachsenen erklären [5,11,18,50].…”

“…If one accepts the hypothesis that there is a sutural-attenuation function mirroring masticatory function, one can perhaps understand the peculiar, so far unexplained situation characterizing the middle-aged group, which exhibits significantly higher bone density. Recent studies have revealed decreasing mechanical strain on the maxilla as individuals get older due to tooth loss and a tendency to suffer from poorer health [2,24]. Less functional strain due to the nature of the diet and diminishing dental status and general health may explain the successful conservative maxilla expansion in adults described in the current literature [5,11,18,50].…”
