“…Reproducibility of NHP was tested by Özbek (19) and Memikoglu (20) who found a consistency with the literature (14,16). Although head types and craniofacial structures are shown to be different in males and females (23), a statistical analysis of sex differences was not made because of the low number of subjects in our study.…”

“…According to this hypothesis, altered nasorespirational function affects NHP and therefore the craniofacial configuration. In the literature, interrelations between NHP and craniofacial morphology have been widely shown (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22). On the other hand, it is well known that head posture can be affected by functions like hearing, sight, equilibrium and even psychological condition, in addition to nasorespirational function.…”

“…Indeed, in the absence of proper occlusion, the ability of the body to adjust its COG becomes impaired (Hosoda et al, 2007). It has been reported that wearing an occlusal splint may allow patients to alter their postural attitude (Milani et al, 2000) and occlusal therapy has been shown to induce a re-equilibrium of masticatory muscles via a descending action resulting in an improved body posture (Bracco et al, 2004). According to a study on relations between dental occlusion and body balance, the myocentric jaw position (right-left muscular equilibrium) improved balance in the frontal plane compared with the centric (most closed, static) position and rest (habitual) position (Bracco et al, 2004).…”

SummaryStudies in the literature show that jaw and neck regions are linked anatomically, biomechanically and neurologically. Voluntary clenching has been shown to improve muscle strength and performance of various motor tasks. Information from the neck sensory-motor system is reported to be important for posture. Hence it is reasonable to believe that activation of the jaw sensorymotor system has the potential to modulate posture. In a sample of 116 healthy subjects, we compared center of gravity (COG) velocity during quiet standing on a foam surface during three test positions: i) resting jaw, ii) open jaw, and iii) clenching; these were tested in two conditions: with eyes open and with eyes closed. The COG velocity decreased significantly during clenching in comparison to both open and resting jaw positions (p<0.0001). This suggests that the jaw sensory-motor system can modulate postural mechanisms. We conclude that jaw clenching can enhance postural stability during standing on an unstable surface in both the presence and absence of visual input in healthy adults and suggest that this should be taken into consideration in treatment and rehabilitation planning for patients with postural instability.

Objectives: Palate morphology is constantly changing throughout an individual's lifespan, yet its asymmetry during growth is still little understood. In this research, we focus on the study of palate morphology by using 3D geometric morphometric approaches to observe changes at different stages of life, and to quantify the impact of directional and fluctuating asymmetry on different areas at different growth stages. Materials and Methods:The sample consists of 183 individuals (1-72 years) from two identified human skeletal collections of 19th and early 20th Century Italian contexts. A 3D-template of 41 (semi)landmarks was applied on digital palate models to observe morphological variation during growth.Results: Asymmetrical components of the morphological structure appears multidirectional on the entire palate surface in individuals <2 years old and become oriented (opposite bilateral direction) between 2 and 6 years of age. Specifically, directional asymmetry differentially impacts palate morphology at different stages of growth. Both the anterior and posterior palate are affected by mild alterations in the first year of life, while between 2 and 6 years asymmetry is segregated in the anterior area, and moderate asymmetry affects the entire palatal surface up to 12 years of age. Our results show that stability of the masticatory system seems to be reached around 13-35 years first by females and then males. From 36 years on both sexes show similar asymmetry on the anterior area. Regarding fluctuating asymmetry, interindividual variability is mostly visible up to 12 years of age, after which only directional trends can be clearly observed at a group level.
