Description
Technical field
The present invention relates to a kind of oral cavity medical apparatus, and in particular to a kind of oral cavity model plotting board and is entered using the device
The method that row describes basal arch line and dental arch curve.
Background technology
Tooth malocclusion clinic orthodontic treatment purpose be balance, stably, it is attractive in appearance.A stabilization is obtained after orthodontic treatment
, the personalized Arch width stability long-term to patient's orthodontic treatment is most important.And Arch width and basal arch form
Closely related, correction clinically, when we design and formulate the therapeutic scheme of correction patient, should take into full account individual difference
Property, and personalized arch wire is bent according to the base Bones morphology of its patient itself, base Bones morphology is mainly determined by inherent cause, basal arch
Form is closely related with Arch width, therefore we recognize that to the very limited degree of change of Arch width in orthodontic treatment, such as
Because arch bend it is excessive caused by denture excessively expand stabilization of the bow not only bad for treatment, and all bone crackings of root of the tooth etc. can be caused
Serious adverse consequences.Arch wire determines position of the patient teeth in jawbone, that is, determines Arch width, the arch wire of larger error can draw
The arch and patient's jawbone basal arch for playing denture are mismatched, and domestic and international numerous studies show that the movement of any tooth in orthodontic treatment should
Using WALA ridge lines be basal arch shape as boundary, beyond limitation correction action not only influence treatment results stability,
And periodontal bone can be caused to ftracture, and a series of serious problems such as fenestration, gingival recession, very there are some researches show labial teeth area tooth lip cheek
The thickness of face alveolar bone is belittled very much, at 2mm, average thickness only has 0.57 ± 0.37mm, backteeth area tooth below alveolus crestal culmination
The thickness of tooth buccal labial surface alveolar bone is average in 1.2mm or so, the alveolar bone thickness belittled Just because of this, so unsuitable bow
Shape, is very easy to cause bone problems of crack.And personalized arch wire that one bends according to basal arch form is in place to after denture
An Arch width matched with basal arch is inherently obtained, the risk that tooth is remedied to outside basal arch shape line can be avoided,
Avoid in corrective therapy because denture arch bend it is unreasonable cause periodontal bone to ftracture, fenestration, gingival recession etc. are a series of
Problem.Therefore, according to base Bones morphology to bend personalized arch wire significant for clinic.
And clinical research shows that WALA ridges can be as the reliable anatomic landmark of base bone, basal arch shape is that WALA ridges connect
Arch formed by line connection, so-called WALA ridges are attached gingiva and most salient point on the tenia of alveolar mucosa boundary.It is clinical normal
It is reference of the basal arch shape as the Arch width for making personalization, specific arch wire with arch formed by the connection of WALA ridges line
Bend with reference to require be Arch width second molar area should in basal arch line 2.2mm, first molar area tooth should be in basal arch
2.0mm in line, second bicuspid area should in basal arch line 1.3mm, first bicuspid area should in basal arch line 0.8mm, it is preceding
Tooth area matches with basal arch shape, but because basal arch shape is discontinuous on model by being distributed in（WALA ridges）Dissect salient point
Constitute, dissection salient point from level to from model some are on the upper side, some are on the lower side, not in same plane, dissect salient point from
Occlusal surface is observed, and some are partially interior, and some are partially outer, so basal arch shape is not an arcuate line of necessary being, clinician
If removing to bend the personalized arch wire for making to match with patient oral cavity Arch width according to this imaginary basal arch form, clinic behaviour
There is bigger difficulty in work, the arch wire bent certainly exists larger error.Clinical clinically doctor uses arch wire at present
Method has two kinds, and method one is to use finished product arch wire, and arch wire arcuate has shaped before dispatching from the factory, arcuate point oval type, sharp round, ellipse
Type, doctor visually observes patient's oral condition, selects a close arcuate, the shortcoming of this method is that selected arcuate does not possess
It is personalized；Method two：Doctor visually observes patient's oral cavity model or intraoral situation, and an arch wire is bent by hand；Two methods institute
Obtained arch wire is all that doctor observes this imaginary basal arch shape line, very rough making arch wire or choosing according to clinical experience
Preforming arch wire is selected, can not several millimeters accurately at all according to the tooth of what tooth position required in theory in basal arch
Seek the arch wire for bending personalization.And use this rough selection or the method for making arch wire usually to cause the tooth of some in dental arch
Tooth, which is offset to outside jawbone, causes all bone crackings of root of the tooth, and gum adheres to the complication such as lost.
