Drilling positioning auxiliary device for tooth implantation

Technical Field

The utility model relates to a positioning auxiliary device, in particular to a drilling positioning auxiliary device for tooth implantation, which can improve the manufacturing efficiency of a tooth implantation guide plate.

Background

Teeth are calcified tissues used for chewing food, when adult teeth are damaged due to oral diseases or external force, the adult teeth cannot regenerate, the alveolar bone and gum can be shrunk after the teeth are damaged, and the eating function is affected.

The artificial tooth implantation is that a hole with proper size is drilled at the gum position where the tooth is damaged, an artificial tooth root is placed in the hole, after the tooth root and the gum grow and heal, an abutment tooth is fixedly arranged on the tooth root, and finally, the artificial false tooth is sleeved outside the abutment tooth, so that the tooth implantation treatment course is completed, and the artificial false tooth can bear the external force during occlusion through the support of the tooth root and the gum, so as to recover the chewing function of the tooth.

The artificial tooth implantation step includes the steps of obtaining oral cavity data of the position to be implanted by the patient through computerized tomography, making the gum model of the patient according to the data, the drilling and the manufacture of the guide plate are carried out on the gum model, when the doctor considers the drilling position and the angle at the edentulous part, the position and thickness of the patient's tooth bone and whether the tooth bone is defective or not, etc. of the patient's oral cavity scanning data are referenced for making empirical judgment and correction, for example, when the tooth bone is thin or defective at the position to be drilled, in order to take into account that the artificial tooth root must be able to withstand the vertical and horizontal pressures after occlusion with respect to the normal tooth at the position after tooth implantation, the drilling position needs to be adjusted to a position to be drilled close to the thicker part of the tooth bone so that the artificial implant can bear the force generated when the upper and lower teeth are occluded without deflection, and therefore, whether the drilling position, direction and angle are proper or not has a decisive influence on the success of the implant operation. The prior art guide plate is manufactured by using a reference rod and a plurality of semicircular guide plates with different diameters, when manufacturing, firstly obtaining oral cavity data of a patient to be implanted with teeth according to computer tomography, marking marks at the missing teeth on a gum model, drilling holes, then penetrating the reference rod into the through holes, clamping the gum model on a parallel measurer (Surveyor)50 shown in fig. 7, and measuring whether the direction and the angle of the reference rod are correct, wherein the parallel measurer 50 comprises a disc-shaped chassis 51, a support 52 is arranged on one side of the chassis 51, a cross arm 53 is arranged at the upper end of the support 52 towards the center of the chassis 51, a vertical arm 54 is arranged at the tail end of the cross arm 53 at the center of the chassis 51, a reference rod 55 is arranged at the bottom end of the vertical arm 54, a tightening knob 531 is arranged outside the tail end of the cross arm 53, and the height of the vertical arm 54 can be adjusted by tightening or loosening the tightening knob 531, a pressing knob 541 is arranged outside the bottom end of the vertical arm 54, and the reference rod 55 can be combined with the bottom end of the vertical arm 54 by the pressing of the pressing knob 541; a disc-shaped supporting seat 56 is arranged at the center of the chassis 51, a universal joint 57 is arranged at the upper part of the center of the supporting seat 56, a model clamping seat 58 is connected on the universal joint 57, the model clamping seat 58 is used for clamping and fixing a patient gum model 60, the direction of the universal joint 57 can be adjusted through the fastening of a fastening knob 561, further, the angle of the model clamping seat 58 relative to a reference rod 55 can be adjusted, whether the direction and the angle of the reference rod are correct can be judged through the angle measurement of the reference rod 55 and a reference rod at the tooth implantation position by a reference parallelism measurer 50, if the direction or the angle of the reference rod is incorrect, the direction and the angle of a newly manufactured gum model perforation need to be judged by repeating the measurement action on the reference rod after the manufacture is finished, the direction and the angle of the reference rod can be judged, troubles are caused by complicated procedures, when the direction or the angle of the reference rod is correct, each guide piece is sequentially sleeved on the reference, the number of the guide pieces is set according to the drilling times required by the evaluation of the patient, and the guide piece with the largest diameter is the size of the actual gum drilling hole.

Then, the gum model, the reference rod and the plurality of guide pieces are coated with an appropriate amount of resin, after the resin is solidified and molded, a guide plate for tooth implantation is formed, the reference rod is taken out, the guide plate to which the guide pieces are attached is taken down, and the guide plate is correspondingly placed at the gum of a patient to perform a drilling operation of the tooth implantation.

In the prior art, a gum model is required to be clamped on a parallel measurer (Surveyor) to measure whether the direction and the angle of the gum model are correct or not so as to manufacture a subsequent guide plate, because the occlusion angles of all teeth of a patient are different, when a patient needs to implant a plurality of teeth, the angle measurement and correction drilling steps are repeated for a plurality of times and then the gum model is respectively installed into the teeth, so that the manufacturing process of the guide plate is complicated and long time is consumed, and in order to ensure the correctness of the drilling position, the direction and the angle, the gum model installed into the gum model needs to be compared with the oral scanning data of the patient again to judge whether the drilling direction or the angle needs to be further corrected or not, and the process needs to consume considerable time, so that further improvement is needed.
