The Investıgatıon Of The Relatıonshıps Between The Natural Head Posıtıon. Posture And Sagıttal Jaw Relatıons

Abstract

Natural head position and natural head posture are terms which have been used to describe the spatial relationships of the head with reference to the true vertical, the cervical volumn, or both. In this study, the relationships between the natural head posture, position and sagital jaw relations had been investigated. As a result, natural head position affected cranial base orientation and this alone produced Class II or Class III effects. Natural head position was also associated with maxillary proognathism whilst natural head posture appeared more closely related to mandibular prognathism.
