Organic Tissue Characteristics on the Pressure Side of Human Premolars Following Tooth Movement.
Maxillary cheek pressures are measured in the molar area, at the teeth and high in the buccal sulcus, in both natural and extended head positions, with teeth at rest and in function. Highest pressur...
A study of the relationship of maximal perioral muscle pressure and tonic resting pressure using a pneumohydraulic capillary infusion system
Lip pressure Oral muscular pressure Pneumohydraulic capillary infusion system
2009/1/23
The tonic(resting) and peak (maximum) lip pressures of 100 subjects were measured. The purpose was to evaluate the validity of the assumption that high peak pressures are indicative of high tonic ...
Pressure from the tongue on the teeth was measured at the upper and lower central incisors and left first molars in 25 young adults with clinically normal occlusion. Repeated recordings with and w...
Influence of surgical tongue reduction on pressure from the tongue on the teeth
Tongue pressure Macroglossia Tongue surgery
2009/1/13
Pressures from the tongue on the teeth were recorded in 21 children and adolescents before and after surgical reduction of the tongue. The recordings were made before surgery, and 6 and 12 months af...
Lip adaptation to simulated dental arch expansion. Part 1: Reliability and precision of two lip pressure measurement mechanisms
Lip pressure Reliability Precision Repeatability
2009/1/9
Understanding the influence of lip and tongue pressure on tooth position requires a reliable method of measuring pressure. A transducer with a beam mechanism has been used extensively in the past....
Pressure on the teeth from the labial soft tissues during the articulation of a given sentence was measured in 24 children, 8 to 14 years old, with normal incisor relationships. The points of measurem...
