Yes, I agree that it is a force system. White, et al., (1976) describes an orthodontic appliance as a means in which mild pressure is applied to a tooth or number of teeth in a predetermined direction. An we know from a physics point that pressure = Force / area (Stackexchange, 2013).
Thus we can deduct that an orthodontic appliance is a system of force(s) which has potential energy that can be applied to move teeth.

I also agree with Ian that it is a force. A force is a load applied to an object that will tend to move it to a different position in space or make space and that is what orthodontic is use for.
Force, though rigidly defined in units of Newtons (mass × the acceleration of gravity), is usually measured clinically in weight units of grams or ounces. In this context, for all practical purposes,1.0 N = 100 gm (the actual value is between 97 and 98 gm)
Yes I agree, as the most common treatment approach to correcting dental malocclusion is through the use of static mechanical forces, which traditionally involves an appliance system of metal arch wires and brackets. The purpose of Static mechanical forces in orthodontic treatments move teeth within the jaw bone and rely on force-induced re-modeling to elicit tooth movement.

No, I disagree because not all orthodontic appliance is use for the purpose of moving teeth.Some are used as space maintainers.There are two types of space maintainers one that is active and one that is passive.The passive space maintainers is used for maintaining the attained position of the teeth and there for have no force system and for this reason it is incorrect to say that all orthodontic appliances is force systems(Singh, 2007).

I am also in agreement. To add to the statement everyone have made. Optimum orthodontic tooth movement is produced by light, continuous force and it’s important that this light force do not decrease rapidly.
I agree, because orthodontic appliances are used for either to maintain position of teeth or to move teeth or arches... the potential energy stored in the wires in retainers resists movement of the teeth, the resistance is due to the stored energy in the wire.

I agree as some of the students have stated not all of the orthodontic appliances are active in the mouth as some of the are just maintainers. However, the maintainer also provides some means of force on the teeth that it maintains or preventing it from drifting. If the maintainer would not have been present, the teeth would have drifted, but with the maintainer in the mouth, the force causing drifting is canceled out by the force applied against the force causing the drifting. The active appliance just apply more force causing a different reaction than retainers.

ReplyDeleteI agree, for movement to take place, work must be done on the tooth. Work is only done in the presence of a force and distance.
