Cheek and tongue pressures in the molar areas and the atmospheric pressure in the palatal vault in young adults

Abstract

The pressures acting on the maxillary and mandibular posterior teeth from the tongue and cheeks were measured in 24 adults aged 22-29 years. In addition, the pressure in the palatal vault was recorded. The pressure at two maxillary (buccal and lingual) and two mandibular (buccal and lingual) measuring points, and in the palatal vault was recorded simultaneously. Repeated recordings of the pressures at rest, and during chewing and swallowing were made. The pressures at rest were of similar magnitude (about 2 g/cm2) at the buccal and lingual sides of the mandibular posterior teeth. The median resting pressure at the maxillary posterior teeth was 2.7 g/cm2 on the buccal side and 1.0 g/cm2 on the lingual side. The difference in the maxilla was significant, but not in the mandible. It was concluded that the equilibrium of tooth position is maintained by the pressure from the cheeks and the tongue. During chewing and swallowing the pressures on the lingual side of the teeth were greater than those on the buccal side. At rest about half of the subjects had a negative pressure at the palatal vault, but no correlations between the resting pressure at the palatal vault and the resting pressures on the teeth were found.

Pressure from the lips and the tongue in children with class III malocclusion

“…Although the etiology for this malocclusion is complex, the effect of muscular function is highly regarded (Singh, 1999). Concerning the effect of muscular function on the maxillofacial morphology, many scholars (Jung et al, 2003;Takahashi et al, 1999;Thüer et al, 1999) have studied the perioral forces exerted on the mixed and permanent dentition utilizing various techniques. So far, no report has defined the perioral forces acting on the deciduous dentition.…”

Presurgical orthopedics by drink plates does not significantly normalize deglutition in infants with cleft lip and palate

“…17,[21][22][23] In order to characterize the robustness of the distinctive parameters, the variation of measurements was analyzed on the basis of a series of three-time repeated pressure monitoring of three subjects of the control group (Table 1). Figure 1.…”

“…17,[21][22][23] Although statistical analyses yielded significant differences between pressure characteristics of the groups, the robustness of pressure parameters needs to be considered in interpreting the data.…”

Pekiştirme Döneminde Yumuşak Doku Adaptasyonunun İncelenmesi

“…Forces generated by extraoral and intraoral soft tissues are known to be a potent factor that can affect the teeth position and malocclusion so an equilibrium between these opposite sided soft tissue pressures should be constructed to provide stability (6,8,9,21,22). In this present study lip, cheek and tongue pressures on the vestibule and palatal/lingual surfaces of the teeth were measured considering the effect of orofacial soft tissues in relapse.…”
