A simple method of preprosthetic molar uprighting with opencoil spring

All teeth are essential, yet in function and influence, some are of greater importance than others, the most important of all being the molars, especially the first permanent molar which according to Edward Hartley Angle is the key to occlusion. Loss of a first permanent molar will make the second and third molars to incline and rotate, canine and premolars to move distally into the molar space, and the opposing first molar to extrude. The over-all objective in uprighting the molar is to optimally position it providing space to restore the lost tooth. Thereby preventing the teeth against inflammatory periodontal diseases and occlusal traumatism, which together determine optimal periodontal environment of the molars and improve masticatory efficiency of the patient.
A sound knowledge of biomechanics is necessary in order to optimize the clinical outcome of uprighting mechanics. When uprighting mechanics is used it is absolutely necessary to consider the extrusive nature of the force system. The uprighting mechanics presented here is very simple and biomechanically efficient to be used in daily practice.
