Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1 ~ 2, this utility model comprises positioning needle 1 and guiding body 2, and wherein when 3-D view board design, described positioning needle 1 is arranged in guiding body 2.Two cramp bars 3 that described positioning needle 1 comprises needle body 4 and arranges in crosswise, the end face of one end of guiding body 2 is along the circumferential direction evenly equipped with four mounting grooves, the two ends of each cramp bar 3 are arranged in different mounting grooves respectively, two cramp bars 3 are namely for ensureing that needle body 4 is positioned at the central axis of guiding body 2, in described guiding body 2, paraffin is housed, namely the needle body 4 of positioning needle 1 inserts in paraffin fixing.
Operation principle of the present utility model is:
When making Dental implantion guide plate, the plantation guide plate 6 not yet completed is sleeved on patient edentulous region plaster model 5, then as shown in Figure 3, this utility model is arranged on the host site position of plaster model 5, above the jaw face that the body 2 that wherein leads is arranged at plaster model 5 host site along the plantation direction of simulation implantation body and described guiding body 2 one end is concordant with plaster model 5 jaw face, described guiding body 2 is through the plantation guide plate 6 be sleeved on plaster model 5, at plantation guide plate 6, paraffin is filled with for being fixed by described guiding body 2 in gap between guiding body 2 and plaster model 5.Positioning needle 1 is arranged in guiding body 2, every root cramp bar 3 two ends of described positioning needle 1 are arranged in mounting grooves different on guiding body 2 end face respectively, thus ensure the needle body 4 of positioning needle 1 and the central axes of described guiding body 2, in guiding body 2 inside, paraffin is housed, the needle body 4 of positioning needle 1 inserts in paraffin fixing.
Before making Dental implantion guide plate, patient takes CBCT, obtain the 3-dimensional image data of jawbone, and the CBCT data of acquisition are realized three-dimensional reconstruction on third party software, arbitrary overturn threedimensional model, the periphery planting environment factor of abundant understanding host site alveolar bone, comprise the thickness of alveolar bone, bone density, the spatial distribution position of nerve and blood vessel etc. in alveolus, based on this, select suitable implantation body's specification (comprising diameter and the length of implantation body), optimized choice goes out the position of best Dental Implant, thus the optimal implanting position threedimensional model image obtained as shown in Figure 4.In the present embodiment, described third party software is Invivo 5.
To wear in patient's mouth with plantation guide plate 6 of the present utility model, wherein needle body 4 length of positioning needle 1 is not to injure edentulous region mucosa under stinging wax-like state and the other end does not contact with to jaw tooth and is as the criterion, then taking CBCT obtains containing secondary CBCT image of the present utility model, pass through third party software again, redesign simulation implantation body three-dimensional position, the axis of simulation implantation body is overlapped with the needle body 4 of positioning needle 1, thus obtains the three-dimensional reconstruction image worn into simulation implantation body implantation position after the plantation guide plate 6 containing guiding body 2 as shown in Figure 5.
Above-mentioned twice CBCT impact is contrasted, simulate in observed and recorded second time CBCT image in implantation body and first time CBCT image and simulate implantation body at middle-distant direction, cheek-tongue direction and extended line are to the gap between jaw biting point, then plantation guide plate 6 is taken off in patient's mouth, and be again applied on plaster model 5, paraffin in positioning needle 1 and guiding body 2 is taken out, then as shown in Figure 6, drive guiding body 2 to move by a locating dowel 7 and adjust guiding body 2 position, after the position of subject-oriented body 2 has adjusted, again positioning needle 1 is put into guiding body 2, and again take CBCT by wearing in patient's mouth with guiding body 2 and the plantation guide plate 6 of positioning needle 1, and the three-dimensional position of simulation implantation body is redesigned by third party software, simulation implantation body is overlapped with the needle body 4 of positioning needle 1, whether the axis then observing this simulation implantation body overlaps with the axis of the simulation implantation body of optimal implanting position threedimensional model image, if overlap, adjust, if do not overlap, repetition aforesaid operations continues fine setting.
