The invention is characterized by simple structure and convenient utilization. It provides auxiliary analytical effect for 3-D data collection and treatment before 3-D module rebuilding scan for lower and upper jaw model, clinical research, anatomical shape of tooth and dentition, alveolar bone of edentulous jaw absorption condition and burnishing surface shape of false tooth in neutral area.
Description
Technical field
The present invention relates to a kind of scanning has the positioner of last mandibular model of certain space position relation and its and is applied to having obtaining and the scan method of reconstructing three-dimensional model of upper and lower gnathode three-dimensional data that the certain space position concerns.
Background technology
The three dimensional data collection method of single gnathode has a lot, and its characteristics and application are respectively arranged.But concerning stomatology, maxillomandibular spatial relationship has further stomatology meaning at present.Japan scholar T.Sohmura etc. once reported high-rate laser scanning dental arch model and the research of rebuilding the interlock threedimensional model in 2000, the VIVID700 spatial digitizer of using Japanese Minolta company scans from 4 angles single model, and the anglec of rotation and index point by goniometer carry out the registration amalgamation.After last mandibular model scans respectively, carry out the scanning of registration marks point again, to set up the coordinate transform of occluding relation.The scanning of interlock model needs 9 times at least about finishing one pair, and step is more, and the number of times of index point registration amalgamation is many more, and error accumulation is also big more.Japanese scholar T.Kojima in 2003 etc. have realized the three-dimensional reconstruction of intercusping bit model by the scanning articulation registration, use the CAMM3 line laser scanner of Japanese ROLAND company, use the record of silicone rubber interlock material lower jaw former, gnathode is gone up in scanning earlier, keep original position motionless at the upper jaw then, load onto corresponding articulation registration and scan again, thereby obtain the mandibular model data, and then finish the model scanning of mandibular model at intercuspal position.Its scan mode is single, can occur many recessed blind areas of falling usually, and articulation registration represents the lower jaw former, has disappearance on the data.Also can obtain the three-dimensional data of lower jaw interlock model in addition by chromatography, its precision also is better than repeatedly the precision of spacescan stack reconstruct, but its data acquisition is destructive, and equipment is also complicated huge.
Oral cavity three dimensional data collection technology is the observation of oral cavity anatomic form, the basis of measuring and analyzing, and its result and oral disease diagnosis, therapeutic scheme design and treatment effectiveness evaluation etc. are closely related.There are many scholars that the method for three-dimensional measurement of dentognathic model is studied both at home and abroad, obtain the reconstruction figure of respond well three-dimensional dentognathic model, can carry out the measurement of the arc length of any 2 distances in space, arbitrarily angled, tooth jaw bow or arbitrary curve and surface area etc. usually.Intercuspal position, edentulous jaw centric relation position etc. all are very important relations in the oral system, but at present, and for having dentognathic model being arranged and having the acquisition method of the edentulous jaw model of centric relation of occluding relation, report is few both at home and abroad.
Summary of the invention
So technical problem to be solved by this invention propose a kind of accurate, simple, efficient, feasible on the positioner of mandibular model, and be applied to the upper and lower gnathode three-dimensional data that has certain space position relation obtain and the scanning of reconstructing three-dimensional model before processing method, for anatomy form, edentulous jaw frontal resorption situation and the neutral area polished surface of denture profile of contact relation, tooth and the denture of the form of clinical research , face good assistant analysis effect is arranged.
Technical scheme provided by the present invention is: a kind of positioner of going up mandibular model, include two pallets and parallel spacing device, and described pallet is discoid, is distributed with through hole on it, and is provided with draw-in groove at its circumferential edges; Two pallets are symmetrical arranged, and the draw-in groove coupling of described parallel spacing device and two pallets snaps in, and is located between two pallets.
For the situation of mandibular model on the clear view, described parallel spacing device is transparent ring.
Further, described pallet is provided with four through holes that internal diameter is identical, and the through hole center is identical with the distance at pallet center, and uniform distribution.
A kind of scanning pre-treating method that has mandibular model on the spatial relation, this method may further comprise the steps:
A. have spatial relation on lower jaw plaster model subscript go out the dentognathic model center line;
B. the lower jaw plaster model is fixed on the positioner of mandibular model, center line aligns with the markings of the following pallet of positioner;
C. play the pallet horizontal positioned, will have the upper jaw plaster model of occluding relation and the lower jaw plaster model interlock coupling that fixes;
D. transparent ring blocks down in the draw-in groove of pallet, simultaneously the draw-in groove of top tray is blocked the other end of transparent ring, the markings alignment of pallet and transparent ring;
E. the through hole from positioner pours into fused wax liquid, makes upper jaw plaster model and top tray maintenance;
The positioner that f. will fix the lower jaw plaster model is fixed on the scanner, scans.
In order to obtain comparatively ideal scanning result, in above-mentioned steps b, that the geometric center and the pallet center of (1) model is overlapping substantially; (2) model is put the sweep limits that does not exceed pallet; (3) the plane of model is substantially parallel with the model holding tray surface.
The present invention has following advantage: this last mandibular model scan method that has spatial relationship is a kind of novel original scan mode, only needs simply, geometric transformation accurately just can finish data transaction.3-D graphic resolution height after the reconstruction, the tooth body anatomic form (as fine structures such as gum edge, cusp, cracks, ditch den) and the Clinical anatomic index point of oral cavity anatomic form are clear and legible, can fully satisfy the needs of clinical treatment, teaching, scientific research; Emulation intercuspal position occlusal position is accurate, can pass through three-dimensional perspective effect observation occluding relation in computer, and its 3-D effect is visual and clear, can finish the combined measurement analysis of mandibular model.
