Description

Technical Field

[0001] The utility model relates to the technical field of dental instruments, in particular to a replaceable bone drilling positioning guide device for dentists. Background Art

[0002] At present, when a patient's teeth are damaged or extracted, dentists generally choose to treat the patient by artificial implantation. Before implanting the denture, a cavity suitable for the later installation of the denture needs to be drilled in the appropriate position of the alveolar bone at the toothless part of the patient's oral cavity. When drilling the cavity with a drill inserted into the oral cavity, the dentist can use a replaceable bone drilling positioning guide device to locate the appropriate cavity drilling position to improve the accuracy of the drilling operation.

[0003] At the same time, the existing patent with the publication number "CN106473823A" records that "the present invention provides a replaceable bone drilling positioning guide device for dentists, which includes a base, a guide member and a positioning block. The base includes a top, a bottom, a first outer wall, a first inner wall, a first guide groove, at least one first groove and at least one second groove; the guide member includes a second outer wall, a second inner wall, a second guide groove, two extensions and at least one convex portion. The present invention uses the design of at least one first groove and at least one second groove to make a drill rod reciprocate in the second guide groove of the guide member toward the long axis direction of the guide member, and the guide member will not move simultaneously with the drill rod; the distance between the extensions is smaller than the diameter of the second inner wall, so that the drill rod is not easy to deviate from the guide groove when drilling, so as to achieve the effect of increasing the stability and accuracy of drilling." It is concluded that the accuracy of dentists in drilling operations can be improved by using the existing bone drilling positioning guide device.

[0004] When implanting a tooth, before the dentist drills a hole in the appropriate position of the alveolar bone, he or she usually needs to cut the gums between the teeth first, and then use tools to move the cut gums to one side.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 , the utility model provides a technical solution:

[0021] A replaceable bone drilling positioning guide device for dentists includes a positioning guide cylinder body 1, adapter blocks 3 are respectively provided on both sides of the positioning guide cylinder body 1 through integral molding, and an auxiliary pressure plate 4 is provided on one side of the adapter block 3 away from the positioning guide cylinder body 1, a limiting clamping plate 5 is fixedly connected to the middle and lower position of the vertical end of the auxiliary pressure plate 4, and a fastening bolt 6 is provided in the middle position of one end of the limiting clamping plate 5, and an auxiliary inclined plate 7 is fixedly connected to the middle and upper position of the vertical end of the auxiliary pressure plate 4.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, a second limiting snap ring 9 is provided at the middle position of the front end of the positioning guide cylinder body 1, and a first limiting snap ring 8 is provided at the middle position of the rear end of the positioning guide cylinder body 1. The second limiting snap ring 9 is symmetrically arranged with the first limiting snap ring 8 along the transverse center axis of the positioning guide cylinder body 1 as the symmetry axis. The first limiting snap ring 8 and the second limiting snap ring 9 are respectively arranged in a "Y"-shaped structure. When the dentist puts the device in the appropriate position of the alveolar bone, the first limiting snap ring 8 and the second limiting snap ring 9 of the positioning guide cylinder body 1 are pre-connected by the limiting slide buckle 10, which will clamp two adjacent teeth of the alveolar bone at the same time, thereby facilitating the whole device to determine a center by two points to realize the positioning and guiding of the drilled cavity; the first limiting snap ring 8 and the second limiting snap ring 9 are close to the positioning guide cylinder body 1. One end of the positioning guide cylinder body 1 is respectively fixedly connected with a limiting slide buckle 10, and the limiting slide buckle 10 has a "T"-shaped structure. The front and rear ends of the positioning guide cylinder body 1 are respectively provided with slide grooves slidably connected to a group of limiting slide buckles 10. When the first limiting clamping ring 8 and the second limiting clamping ring 9 are respectively installed, the limiting slide buckle 10 adopts a "T"-shaped structure, which can better fit with the slide grooves reserved at the front and rear ends of the positioning guide cylinder body 1, and also makes the composed clamping structure not easy to loosen; the middle position of the positioning guide cylinder body 1 is provided with a guide groove 2 through integral molding, and a group of auxiliary inclined plates 7 are relatively arranged along the center point of the guide groove 2. When the drill bit is lowered into the guide groove 2 for drilling, a group of auxiliary inclined plates 7 with an inclined surface structure will provide guiding assistance to the drill bit.

[0023] The auxiliary pressing plate 4 and the limiting snap ring are arranged vertically. The first limiting snap ring 8 and the second limiting snap ring 9 are made detachable to accommodate teeth of different sizes. According to the different sizes of teeth to be pressed against, the first limiting snap ring 8 and the second limiting snap ring 9 of different sizes can be replaced, which is also convenient for cleaning. After replacing the appropriate first limiting snap ring 8 and the second limiting snap ring 9, the whole device is put down as a whole. When it is not necessary to press against the teeth, one or two limiting snap rings are removed before use.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, two auxiliary pressure plates 4 are symmetrically provided, and the outer shape of each auxiliary pressure plate 4 is an inverted L-shape. The vertical end of the auxiliary pressure plate 4 and the limiting clamping plate 5 are vertically arranged, and the fastening bolt 6 and the adapter block 3 are threadedly connected. The height of the auxiliary pressure plate 4 is greater than the height of the positioning guide cylinder body 1. When the positioning guide cylinder body 1 is accurately placed in the appropriate position of the alveolar bone, a group of auxiliary pressure plates 4 will respectively cover and resist the two pre-cut gums to prevent the repositioning problem of the everted gums from affecting the dentist's normal drilling operation.

[0025] Workflow: Before the dentist uses the replaceable bone drilling positioning guide device for treatment, the limiting clamp plate 5 and the adapter block 3 can be connected simultaneously by fastening bolts 6, so that a set of left and right auxiliary pressure plates 4 can be installed on both sides of the positioning guide cylinder body 1. Then, when the artificial implant operation is actually carried out, the gums between the teeth can be cut and turned outward, and then the positioning guide cylinder body 1 can be placed in the appropriate position of the alveolar bone using tools, and after the first limiting clamp ring 8 and the second limiting clamp ring 9 are respectively pressed against a set of adjacent teeth of the alveolar bone, the drill bit can be gradually lowered along the inclined surface of the auxiliary inclined plate 7. The drill bit is placed into the guide groove 2, so that the drill bit can drill a cavity in the middle of the alveolar bone under the guidance of the positioning guide, so as to implant the denture through the cavity later. When the positioning guide cylinder body 1 is accurately placed in place, a group of auxiliary pressure plates 4 can resist the gums that are prone to eversion. Because the auxiliary pressure structure composed of the adapter block 3, the auxiliary pressure plate 4, the limiting clamping plate 5, and the fastening bolts 6 can use the pressure covering method to moderately limit the gums to the outer sides of the positioning guide cylinder body 1, thereby preventing the everted gums from being repositioned and covering the positioning guide cylinder body 1, thereby affecting the drilling.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
