Biomechanical Consideration to the Extraction Site in Orthodontics; A Theoretical Approach
Authors: H.M. Abdel-Kader
Abstract: In orthodontics, if we would like to achieve the long-term stable dental occlusion within the range of normality and to satisfy precisely our treatment objectives, we have to have long-term stable static and dynamic balanced occlusion within the stomatognathic system. Systematic understanding of orthodontic mechanics and biomechanics is the key stone in this respect. Orthodontics is a very unique specialty dealing with multifactorial phenomena, dental malocclusion, to approach it we have to go methodically to other related fields. The steering signals for successful orthodontics are to be accounted first-of-all with the developing waves of stresses and strains in the periodontium in response to the orthodontic force. Full understanding of the sequence of events in response to the force of occlusion is the key to explore this crucial subject. The objective of this study was to apply basic biomechanical considerations in understanding the inﬂuence of extraction of teeth; mesial versus distal to the permanent first molars hoping to open a panel of free discussion in respect of our clinical experience.
