Description
Technical field
What the present invention relates to is a kind of for the multifunction traction rectification external member of correcting embedded tooth.Belong to technical field of medical instruments.
Background technology
In human oral cavity, labial teeth or the bicuspidal impaction of hiding are comparatively common, and embedded tooth not only influences the attractive in appearance of patient, destroy masticatory function, also cause various oral diseases easily.At present main antidote is the surgical operation just abnormal traction method of associating of windowing clinically.The key step of this method is as follows: be adhesively fixed formula orthodontic appliance and lay and correct main arch wire of other teeth in mouth at first; By embedded tooth position, X-ray film location, surgical operation cuts and hides the corresponding surperficial mucosa of corona then, digs alveolus mucoperiosteum lobe, and cuts part alveolus sclerotin to expose the corona of embedded tooth.Then need a bonding finished product orthodontic bracket on this embedded tooth corona, draw embedded tooth is carried out reinforcing on aforementioned orthodontic master arch wire at one section finer wire of ligation on this bracket and with its two free-ends bolt knot, reset at last to close and sew up alveolus mucoperiosteum lobe.In the further consultation process afterwards, afterburning by continuous traction, the eruption of guiding embedded tooth is to the oral cavity.
What use in the method at present is common finished product orthodontic bracket, and this kind bracket exists following shortcoming and defect:
The particular location that can not show embedded tooth in 1 distraction procedure intuitively: because embedded tooth and common orthodontic bracket adhered thereto are sightless before embedded tooth is pulled out gingival mucosa, so in this distraction procedure, the doctor can only rely on the clinical experience of himself or repeatedly the X ray examination could judge the position of embedded tooth and traction progress.Because individual patient difference and doctors experience difference usually cause misjudge, and X ray examination repeatedly obviously also is the health that is unfavorable for the patient.
2. can't make judgement to the space three-dimensional attitude of embedded tooth in the distraction procedure: because embedded tooth is buried invisible in alveolar bone, so in the distraction procedure, the doctor can't to its space three-dimensional attitude with and make accurate judgement with the spatial relationship of adjacent teeth, treatment belt bears the character of much blindness.
3. in the distraction procedure, the space three-dimensional attitude of embedded tooth and the path of specifically dividing a word with a hyphen at the end of a line are difficult to control: during because of traction, common orthodontic bracket can only carry out reinforcing at just abnormal main arch wire by ligation silk bolt knot, the doctor can't carry out accuracy controlling to size, the direction of power, more can't produce the needed couple of control embedded tooth space three-dimensional attitude, moment.So in the distraction procedure, in fact the space three-dimensional attitude of embedded tooth and the path of specifically dividing a word with a hyphen at the end of a line can't effectively be controlled, this just produces very big rectification risk.Because touching the root of the tooth of adjacent teeth probably in moving process, embedded tooth cause the latter's pressurized to absorb.
4. base plate and not driving fit of facing, stressed back expulsion rate height: the base plate of finished product orthodontic bracket is that the form of the central area of lip, buccal surface according to normal tooth is made.But the embedded tooth facing that exposes in the windowing often is not this central area.This just causes shape and not of uniform size the causing of the embedded tooth facing of finished product bracket and exposure, and the two can not be fitted fully, often causes orthodontic bracket to come off from the embedded tooth facing after stressed, needs again the surgical operation bonding of windowing, and this has just increased patient's misery.
Summary of the invention
What the present invention proposed is that a kind of multifunction traction for the rectification embedded tooth is corrected external member, its objective is the inherent shortcoming that overcomes common orthodontic bracket, avoids the infringement to the patient when finishing the rectification target.
One, parts of the present invention, concrete structure and mutual annexation are as follows:
1) product of the present invention is formed:
Product of the present invention is made up of implantation piece and outer plugin two parts.
The concrete structure of outer plugin comprises: 1 artificial tooth sheet, 2 vertically to traction conduit draw-in groove.
2) being connected of implantation piece and outer plugin:
With outer plugin vertically to traction conduit draw-in groove be connected to implantation piece vertically on the traction conduit, realize the reliable connection of outer plugin and implantation piece, this moment, the artificial tooth sheet just can show locus and the 3 d pose of embedded tooth intuitively.
Two, designing and manufacturing method of the present invention
1) designing and producing of implantation piece:
At first obtain embedded tooth by tractus pyramidalis CT and reach the density data of sclerous tissues on every side, rebuild the 3 D stereoscopic image of patient's denture (comprising embedded tooth) by computer image processing.
The design of personalized base plate: according to window position and the concrete operation pathway of design, on the 3 D stereoscopic image of the embedded tooth of computer reconstruction, generate personalized base plate by the cad technique design, this bonding plane form that just can guarantee it is consistent with the embedded tooth facing size and form that actual operation exposes, the two can be fitted fully, and this just greatly reduces the expulsion rate that is subjected to embedded tooth behind the pull strength.
The making of implantation piece: generate personalized base plate, guide rod, level to reaching vertically behind the traction conduit with the cad technique design, related data is imported the 3D printer, print the plastic pattern of implantation piece, then by operations such as embeddings, cast out personalized implantation piece with the fusible pattern microtechnic.
2) making of outer plugin:
The design of outer plugin and making also are to utilize cad technique to generate the on all four artificial tooth sheet of embedded tooth corona labial surface profile earlier, design one then at the back side of this artificial tooth sheet vertically to traction conduit draw-in groove, and the labial surface major axis of its long axis direction and artificial tooth sheet is parallel.In addition, the size and Orientation of this draw-in groove can precision-matched to the traction conduit with the vertical of implant top.
The data input 3D printer of the outer plugin that designs can be printed this outer plugin of plastic material.
Three, using method of the present invention:
Routine installs and fixes orthodontic bracket on other tooth in advance, lays just abnormal main arch wire and corresponding anchorage device.
The exposure embedded tooth of performing surgical operation then, bonding implant on its facing.According to designing the bonding personalized base plate in facing position in advance, and its guide rod is passed outside the alveolar mucosa.At this moment, the level of guide rod upper end is to just being emerging in gingival surface with vertical to the traction conduit.
Directed traction is sprouted to helping with vertical: with thin ligation silk penetrate level to traction tube or, and by the elasticity chain ring be installed in other teeth on just abnormal main arch wire be connected, thereby embedded tooth is produced needed pull strength to induce its eruption.The directed traction to embedded tooth that this external member that Here it is has helps sprouts function.
Three-dimensional appearance control: the 3 d pose to embedded tooth control effectively if desired, and the level that the just abnormal stainless steel side silk that bends shaping can be penetrated is to the traction conduit, and is connected on the anchorage device that is installed on other teeth.Utilize this square arch wire and level to the interaction of traction pipe inner wall, both can produce the control necessary couple of embedded tooth 3 d pose and moment.This external member that Here it is is to the control function of embedded tooth 3 d pose.
Locus adjustment and the path control of dividing a word with a hyphen at the end of a line: the root of the tooth of embedded tooth and adjacent teeth adjoins, and may come in contact in the distraction procedure, causes the root of the tooth of these teeth that repressive absorption takes place.For this reason, often need adjust and its path of dividing a word with a hyphen at the end of a line is controlled the locus of embedded tooth.For example: can in the traction conduit, insert one section rigidity orthodontic bow-wire in the level of implant, be worn over the traction India rubber circle that anchorage device on other tooth adds a horizontal direction in level to traction conduit and dress then, can be so that embedded tooth carries out level to movement along the rigidity orthodontic bow-wire under the effect of pull strength.This external member that Here it is is to the adjustment function of embedded tooth level to the locus.
The visualization display of embedded tooth locus and 3 d pose: with the outer plugin back side vertical to traction conduit draw-in groove be stuck in implant vertically on the traction conduit, the 3 d pose that can intuitively show embedded tooth by the 3 d pose of artificial tooth sheet, artificial tooth sheet and alveolar mucosa distance can reflect the eruption depth of embedded tooth.
Four, major function of the present invention:
The visualization display of 1 embedded tooth position and attitude: intuitively show position and the space three-dimensional attitude of embedded tooth, predict that it moves the walking along the street footpath.Need not periodic X ray examination, by outer plugin is connected to implantation piece vertically on the traction conduit, just can show locus and the 3 d pose of embedded tooth by outer plugin artificial tooth sheet intuitively, avoid the blindness of in the past drawing.
Accurately control the space three-dimensional attitude of embedded tooth and the path of dividing a word with a hyphen at the end of a line in 2 distraction procedure: the implantation piece guide rod stretches out outside the alveolar mucosa, two orthogonal traction conduits on the bar.Drag spring thimble internal diameter and existing orthodontic bracket system matches can be rescued design by personalized stainless steel square silk, bend fixing and the traction reinforcing, thereby accurately control direction and the path that embedded tooth moves; Simultaneously two orthogonal drag spring thimbles cooperate bending of each yeast inoculation on the stainless steel square silks, can realize that integral body, rotation, inclination, the control root to embedded tooth moves, the effective 3 d pose of control tooth in traction.
3 personalized implantation pieces: precision-investment casting goes out personalized whole implantation piece makes traction more comfortable and convenient.Wherein, the personalized base plate of casting can be fitted fully with the facing of surgical exposure; Window position, operation pathway of the design consideration of guide rod determined, embedded tooth is drawn under visual; The use that cooperatively interacts of two orthogonal traction conduits, it is three-dimensional controlled to realize that embedded tooth moves.
