The clinical diagnosis of temporomandibular disorders in the orthodontic patient.

Because many of the diseases and disorders that affect the temporomandibular joint (TMJ) and associated masticatory muscles occur in the age group of patients generally seen by the orthodontist, their recognition is of great importance in planning and performing orthodontic therapy. This article discusses the diagnosis and clinical significance of the various conditions that may be encountered.

Effect of removing impacted third molars on plaque and gingival indices.

This study investigated the effect of removal of partially erupted mandibular third molars on the plaque and gingival indices. Sixty patients were studied and assigned to one of three groups: control, asymptomatic partially erupted third molars, and symptomatic partially erupted third molars. Plaque and gingival indices were scored for the second molar to the canine in all four quadrants preoperatively and again at 6 weeks after surgery. Results show that removing impacted teeth may provide some benefit in terms of improved gingival health.

Analysis of seating and fracturing torque of bicortical screws.

The purpose of this study was to analyze and compare the seating and fracturing torque of 2.0-mm- versus 2.7-mm-diameter titanium screws. Six cadaver mandibles were sectioned at the symphysis and 20 drill hole locations were chosen on each half. Half the holes were designated for the 2.0-mm screws, tapped and nontapped, and the remaining half for 2.7-mm screws, tapped and nontapped. The maximum torque leading to the screw seating or fracturing was recorded using an electric torque tester (Artech Reliance, Chantilly, VA). The mean maximum seating torque for the 2.7-mm screws, tapped and nontapped, was 30% of that measured for the 2.0-mm screws. The mean maximum seating torque for all tapped screws was 35% less than for all nontapped screws. The region of the mandible requiring the greatest seating torque was the symphysis, followed by the body, condyle, ramus, and angle. None of the 2.7-mm screws fractured; however, 10% of the 2.0-mm screws fractured. Three were located in the symphysis and one in the ramus. With the 2.0-mm screws that did not fracture, the seating torque in the nontapped holes was 59% greater than in the tapped holes. With the 2.0-mm screws that fractured, the mean maximum fracturing torque was 64% greater than for those screws that did not fracture. This study shows that small screws placed in the mandible require greater seating torque, regardless of whether the holes are tapped, and that there is an increased chance of small screws fracturing in certain regions.
