Splints made of wire and composite: an investigation of lateral tooth mobility in vivo.
In 103 posttraumatic splints, later tooth mobility was measured with Periotest immediately before and after the routine splint removal. The splints were made of composite resin and an 0.017 X 0.025" orthodontic steel wire. 481 teeth were measured. A statistic evaluation revealed that the immobilisation effect did not exceed normal tooth firmness. Fixation to one neighbouring tooth had less effect than fixation to two. Adjacent tooth gaps reduced the effect. Splint extensions had no influence. With the use of the Periotest device, more than 50% of all teeth with a true mobility of 20 Periotest-units or more were detectable as mobile in spite of the fixed splint.
