Title: Study of extraoral force delivery systems using holographic techniques
Issue Date: 2014
Abstract: Extraoral traction is still one of the most reliable methods used during active orthodontic period especially in growingpatients [1]. It is a practical and cost-effective method for attaining extra anchorage in a variety of treatment situationsand it can be used either with orthodontic or orthopaedic purposes [2-3]. It is imperative for the clinician to consider thequality of the force systems, taking into account the degradation of its components, due to loss of elastic memory andmaterial fatigue. Thus it is utterly important to understand the characteristics and mechanical behaviour of the extra oraldevice elements.This investigation intended to compare extraoral force delivery systems through the study of the mechanical behaviourof the plastic strap component. For this study two methods were chosen, a non-experimental technique, Finite ElementAnalysis (FEA), and an experimental technique ESPI. Two different manufacturers of extraoral traction systems wereselected based on their market price, one of them being significantly more expensive than the other. The assessment ofthis data may validate the choice criteria between these two market options.
