INTRODUCTION The objectives of this research were to assess skeletal and dental changes in patients with Class II malocclusion treated with the edgewise crowned Herbst appliance in the early mixed dentition and to measure the stability of treatment after a second phase of fixed appliance therapy. METHODS Twenty-two patients (ages, 8.4 ± 1.0 years) with Class II Division 1 malocclusion treated...

INTRODUCTION Rapid palatal expanders (RPEs) have attachments cemented to the teeth and a screw that covers the palate. Because of their position and relative size, RPEs can affect speech. Our objective was to assess speech perturbation and adaptation related to RPE appliances over time. METHODS RPEs were planned for the treatment of 22 patients in the orthodontic clinic at the University of T...

The effect on isometric strength of the shoulders and limbs while biting in habitual occlusion, on a bite-elevating appliance and on a placebo appliance was analyzed. Twenty female volunteer patients, presenting with temporomandibular pain dysfunction syndrome and obvious loss of vertical dimension, served as subjects. All were weaker to the manual application of the isometric Deltoid Press (ID...

A simple fixed-hook driving appliance is described, suitable for upper-limb amputees, and its function compared with that of the commonly available ball-and-cup device. The hook is reliable, safe and inexpensive. An attachment is also described which fits on to gear levers, allowing the use of the driving appliance to change gears manually.

A case report of an electrical burn oF the lips in a 22-month-old child is presented. The principles oF early medical and dental treatment and the sequence of appliance Fabrication are detailed. The appliance Fabrication utilized in this case is unique because it is an intraoral treatment approach to a commissural burn in a child that had not yet erupted primary second

Three specific orthodontic tooth movement genes, that is, FCRL1, HSPG2, and LAMB2 were detected at upper first premolar (with appliance) dental pulp tissue by using GeneFishing technique as compared to lower first premolar (without appliance). These three differentially expressed genes have the potential as molecular markers during orthodontic tooth movement by looking at molecular changes of p...

Moses describes an appliance termed a "passivator" which supports the mandible in an anterior and slightly open bite yet neither allows nor causes undesirable orthodontic tooth movements. This appliance is reported to support the patient’s mandible during sleep, prevent collapse of the pharyngeal musculature, allow greater volume of space for tongue activity and prevent incorrect swallowing and...

To investigate the effect of restriction of mandibular movements during sleep on jaw-muscle electromyographic (EMG) activity. Eleven healthy subjects (four men and seven women; age, 25·9 ± 3·1 years) with self-reports of sleep bruxism participated in three randomised sessions with three different types of oral appliances: (i) full-arch maxillary and mandibular appliances which did not allow any...
