(2) according to patient's mandibular protraction amount with open length and the height adjustment that the interlock amount determines that the guiding incline tooth closes pad before lower jaw, controls the mandibular protraction amount by computer and open the interlock amount on three-dimensional dentognathic model.
Described three-dimensional correction facing is by the following steps manufacturing:
(1) at first obtain the upper digitized three-dimensional dentognathic model of mandibular teeth of patient, three-dimensional dentognathic model is cut apart, form independent tooth model, determine the target location of each tooth model.
(2) relatively moving direction and distance are also determined in the initial position of each tooth model and target location.
(3) adopt rapid prototyping technology to make the three-dimensional correction facing according to the position of each tooth model.
In a preferred embodiment provided by the invention, wherein be divided into several stages according to the rectification situation, the digitized denture production phase resin tooth mould that consists of according to the three-dimensional tooth modal position in each stage.
In a preferred embodiment provided by the invention, the position movement distance in the wherein said stage is set in 0.2-0.8mm.
In a preferred embodiment provided by the invention, also be provided with positioning convex on wherein said three-dimensional correction facing.
In a preferred embodiment provided by the invention, wherein said three-dimensional correction facing comprises resin tooth mould and soft rete and hard film layer.
In a preferred embodiment provided by the invention, wherein said coating layer comprises soft rete and hard film layer, and described soft film lamination is on resin tooth mould, and described hard film layer covers on described soft rete.
In a preferred embodiment provided by the invention, the thickness of wherein said hard film layer is 0.6-1.0mm.
In a preferred embodiment provided by the invention, the thickness of wherein said soft rete is 0.3-0.8mm.
The present invention utilizes computer technology to prepare the leading device of lower jaw, adopt computer accurately control the mandibular protraction amount of orthodontics and open the interlock amount at three-dimensional dentognathic model, reduce in correcting process the damage to tooth and gingiva, improve the comfort level of edible for patients, straightening of teeth in the lump when correcting positions of maxilla and mandible.

The specific embodiment
The method for preparing the leading device of lower jaw provided by the invention adopts computer accurately control orthodontics and mandibular protraction amount and open the interlock amount.
Below the leading device manufacture method of stealthy lower jaw provided by the invention is described in further detail, in order to the content of the invention better is described, but the content of embodiment does not limit the protection domain of the invention.
The prepared leading device of lower jaw of the present invention is comprised of a plurality of appliance, is respectively used to the rectification of different phase lower teeth.
Each independent appliance comprises the three-dimensional correction facing (20) that the front guiding incline tooth of lower jaw closes pad (10) and makes of macromolecular material.Before lower jaw, the guiding incline tooth closes the occlusal surface place that pad (10) is arranged on three-dimensional correction facing (20), three-dimensional correction facing (20) is enclosed within and plays maintenance on tooth and correct denture uneven, and before lower jaw, the guiding incline tooth closes pad (10) and plays the effect that guides mandibular protraction simultaneously.
The manufacture method that the front guiding incline tooth of lower jaw closes pad (10) is as follows:
At first, obtain the upper digitized three-dimensional dentognathic model of mandibular teeth of patient, and the definite up and down jaw position relationship that be engaged in three-dimensional dentognathic model actual in the patient.Make patient's protrusive articulation, determine leading target occlusal position according to face type improvement degree, definite relative upper jaw of target lower jaw position on digitized three-dimensional dentognathic model.According to patient's mandibular protraction amount with open the interlock amount and adjust length and the height that guiding incline tooth before lower jaw closes pad, control the mandibular protraction amount by computer and open the interlock amount on three-dimensional dentognathic model, be complementary to keep the mandibular protraction amount and to open the interlock amount, close length and the height adjustment patient mandibular protraction amount of pad and open the interlock amount by changing the lower jaw tooth.
The manufacture method of three-dimensional correction facing (20) is as follows:
At first obtain the upper digitized three-dimensional dentognathic model of mandibular teeth of patient, will obtain three-dimensional dentognathic model and cut apart, form independent tooth model.The tooth model of these Digital Three-Dimensionals is arranged, determined the target location of each tooth model.With the initial position of each tooth model and target location relatively, resolve into a plurality of stage positions according to what the sufferer practical situation will move, each stage position displacement is controlled between 0.2-0.8mm.
Consist of digitized denture by each stage tooth model position, adopt rapid prototyping technologies to make the resin tooth mould of stages according to these denture situations, then suppress coating layer on resin tooth film, thereby make the three-dimensional correction facing.The coating layer of compacting comprises soft rete and the hard film layer that hardness is different, and soft film lamination is on resin tooth mould, and described hard film layer covers on soft rete.The thickness of hard film layer is between 0.6-1.0mm, and the thickness of soft rete is between 0.3-0.8mm.Soft rete plays the straightening of teeth effect, and hard film layer plays maintenance and supporting role.Also be provided with positioning convex on the three-dimensional correction facing, positioning convex has the leading amount of definite lower jaw.
What Fig. 1-5 showed is the view of all angles under the leading device user mode of lower jaw provided by the invention, and in figure, the front guiding incline tooth of lower jaw closes the occlusal surface place that pad (10) is arranged on three-dimensional correction facing (20), is used for denture and corrects and mandibular protraction.
Between the maxillary teeth of sufferer and mandibular teeth, appliance is set, appliance by lower jaw before the guiding incline tooth close pad (10) location, and form tooth jaw location on three-dimensional dentognathic model, the location determines that the patient rescues the maxillomandibular position relationship that should reach.Amount and interlock opening that before the computer control lower jaw, the guiding incline tooth closes the length of pad (10) and highly regulates mandibular protraction realize by independent complete appliance.Every cover appliance is realized the progressively leading until reach the target location of lower jaw, and under every cover appliance accurately controls by computer, the coordination that keeps the protraction amount and open the interlock amount.
Above specific embodiments of the invention are described in detail, but it is just as example, the present invention is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that the present invention is carried out and substituting also all among category of the present invention.Therefore, not breaking away from impartial conversion and the modification of doing under the spirit and scope of the present invention, all should contain within the scope of the invention.
