Description
Technical field
This utility model relates to a kind of three-dimensional orthodontic force dynamic measurement device simulating Tooth Movement.
Background technology
Mouth cavity orthodontic be for tooth arrangement deformity or plate bite (tooth is combined into a word, lower same), the NITI Ω arch wire apparatus utilizing arch wire, bracket etc. to form, or the stealths such as facing can the formula of plucking rescue apparatus, three-dimensional is applied to tooth and rescues force and moment, adjustment face skeleton, tooth and the triangular balance and coordination of jaw facial muscle meat, improve face type, aligning improve masticatory efficiency after rescuing after a while.
In correction, be no matter the edgewise appliance in NITI Ω arch wire or straight wire appliance, or facing etc. can pluck formula invisible orthotic device, is all implemented on tooth by sustained load by the distortion of arch wire or facing, realizes the movement of tooth.Therefore appliance is supplied to moving process and the amount of movement that the three-dimensional orthodontic force of tooth and moment will determine tooth, will realize tooth movement accurately, as required, first must know clearly the force and moment that abnormal correction system provides in orthodontic treatment process.And tooth is in moving process, and due to the change of position, the power that appliance provides is also in real-time change.Exactly because many undesirable Tooth Movements is to the understanding of orthodontic force and control unintelligible causing.Incorrect force and moment can cause Tooth Movement excessive or not enough, now to need according to practical situation adjustment appliance, with afterburning or subtract power, will greatly extend the time of rescuing like this, the absorption of periodontal tissue may be caused simultaneously, increase the risk rescuing failure, occur larger uncertainty.
