Case reports on tooth positioners using LTV vinyl silicone rubber.

Properties of LTV vinyl silicone rubber-based resilient denture base liner and directions for use.

“…8 Water absorption of resilient material toxic or poisonous substance. Furthermore, patients wearing a tooth positioner, which has a basically similar composition to that of vinyl silicone rubber [5][6][7][8], and a further twenty-five patients (whose cases will be described later), used this liner with their dentures, and none of them reported any complaints or discomfort. During a three-year test period, no inflammation or swelling was observed among any of the former patients.…”

Influence of material choice on the force delivery of bimaxillary tooth positioners on canine malpositions

“…The tipping of teeth within reasonable limits of 1-2 mm is frequently described as the most relevant tooth movement during positioner therapy [3,6,10,21]. Rotational correction is advantageous in incisors but difficult in all other teeth [4].…”

“…Rotational correction is advantageous in incisors but difficult in all other teeth [4]. Finally, extrusive and intrusive movements are believed to be unpredictable [6,21]. In addition to moving individual teeth, the positioner has also been advocated for improving the centric condylar position.…”

“…Eine Zahnkippung innerhalb vernünftiger Grenzen von 1-2 mm wird oft als die relevanteste Art der Zahnbewegung wäh-rend der Therapie mit dem Positioner beschrieben [3,6,10,21]. Die Durchführung von Rotationskorrekturen sind bei den Frontzähnen günstig, aber für alle anderen Zähne schwierig [4].…”

“…Die Durchführung von Rotationskorrekturen sind bei den Frontzähnen günstig, aber für alle anderen Zähne schwierig [4]. Schließlich werden Extrusions-und Intrusionsbewegungen als nicht vorhersagbar bezeichnet [6,21]. Neben der Bewegung einzelner Zähne ist die Verwendung eines Positioners auch für eine verbesserte Zentrierung der Kondylenposition befürwortet worden.…”
