Description

Technical Field [0001] The present invention relates to a surgical guide system for dental implants having an external injection device,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a surge guiding system for use in dental implant treatment, and more particularly, to a surge guiding system for use in a dental implant system including an external pouring apparatus for cooling heat generated when a drilling operation is performed on a gum bone using a surge- And more particularly to a surgical guide system for operation.

A dental implant (hereinafter simply referred to as an "implant ") is also called an artificial tooth or a third tooth. That is, the implant is a dental treatment method that restores the function of a natural tooth by implanting a biocompatible material such as a titanium-based metal artificial tooth on a portion of a tooth having a defect or a gum bone of a tooth extracted from the tooth, Or an artificial tooth itself.

These implants have a variety of structures, and basically consist of fixture, abutment, and artificial crown elements, as can be seen from various known documents. The fixture is formed into a screw shape of a material having excellent biocompatibility so that the bone is fused to the alveolar bone (gum bone) in which the teeth are lost, and the abutment is provided with an artificial crown for chewing and beauty As a structure, it is combined with screw fixture or interference fit in the lower fixture.

Implantation is performed by placing a fixture on a perforation formed on the alveolar bone using a drill. The position and depth of the implant, taking into consideration various factors such as the patient's tooth condition, the position of the tooth requiring the implant treatment, And the direction of the drilling is to be determined, the drilling procedure for forming the perforation is different for each patient.

Because the drilling procedure of the alveolar bone is different for each patient, it is very difficult to form a hole in the alveolar bone precisely as desired even for the beginner and the experienced person. Failure to form the perforation in the alveolar bone results in poor fixture placement and prognosis of bone fusion, which is an important factor in lowering the success rate of the dental implant procedure.

In order to solve such a problem, a method of using an auxiliary mechanism such as a surgical guide as in Patent Document 1 has been gradually spreading in recent years. The surgeon guide is made of a synthetic resin material that is easily molded into a designed shape and has a guide hole for guiding the drilling operation corresponding to the implant operation plan in a state fixed to the inside of the patient's mouth.

The guide hole is formed on the surge guide so as to correspond to the drilling angle of the drilling operation. Thus, the outer circumferential surface of the implant drill is rotatably supported on the inner circumferential surface of the guide hole to guide the drilling operation accurately. In some cases, a guide sleeve may be equipped with a cylindrical sleeve of a metal material to reinforce the support strength of the implant drill.

The use of surge arresters has had a great effect on improving the success rate of dental implant surgery, but one problem has arisen in clinical practice. This is a problem related to denudation of the alveolar bone during the drilling process. When the surgeal guide is not used, there is no problem in cooling the drill by directly injecting the washing water because the surgical site is exposed. However, Since the drill is inserted into the guide ball, it is difficult to inject the surgical guide when using the sagittal guide.

Failure to adequately cool the surgical site to drill is likely to cause thermal denaturation of the alveolar bone tissue and degeneration of the alveolar bone tissue will adversely affect the bone fusion of the fixture. In order to solve this problem, a method has been proposed in which a drill is pierced or poured through a drill outer circumferential surface, but a large effect can not be expected because it is difficult for a sufficient amount of wash water to be poured.

FIG. 1 is a view showing the overall configuration of a surge guidance system 100 for dental implant treatment according to the present invention. FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, Will be described in detail.

As shown in the drawings, the surge guiding system 100 for dental implant treatment of the present invention is provided with a syringe guide 110 mounted in the mouth of the subject, together with a syringe tube 120, 120 and a rinse water supply source 130 for pressurizing and supplying the rinse water.

The surge guide 110 is provided with a guide hole 112 for guiding a drilling operation for performing a dental implant procedure. The surgeon guide 110 surrounds and fixes the tooth placement target part 150 based on the three-dimensional data acquired from the inside of the mouth of the subject Lt; RTI ID = 0.0 > a < / RTI > dental mouthpiece. However, the surge guide 110 is fixed to the teeth or gums around the subject 150 and does not necessarily have to be an arch that covers the mandible or the maxillary dental arch, and a portion of the dental arch It can be made in a short wrapping form. The structure of the surge guide 110 itself can be referred to in Patent Document 1.

One end 121 protrudes out of the surge guide 110 and the other end 122 protrudes outward from the surge guide 110. The end guide 122 extends from the end of the surge guide 110, And extends toward the tooth placement target portion 150 while bypassing the guide hole 112 of the tooth placement portion 150. [ The main containment tube 120 refers to a pipe member forming a passage for injecting externally supplied washing water toward the tooth placement target portion 150 as the term is used.

Here, the main receiving tube 120 extends to the tooth placement target portion 150 by "bypassing " the guide hole 112 of the surge guide 110, In a manner that does not interfere with the drill entering along the length of the drill. For example, the structure in which the other end 122 of the main containment tube 120 extends toward the tooth placement target portion 150 can be configured in a variety of ways. At least the other end 122 of the main take- Should not be involved. Referring to the embodiment shown in FIG. 2, the other end 122 of the drinking water tube 120 is located outside the cylindrical space defined by the inner circumferential surface of the guide hole 112, thereby bypassing the interference with the entering space of the drill .

The rinsing water supply source 130 collectively refers to means for supplying rinsing water for cooling the heat generated in the cutting process of the drill. Here, since the washing water supply source 130 must be able to discharge the washing water by applying pressure, it may be appropriate to use a syringe or a sap pack, which is commonly used in a medical field, as the washing water supply source 130. In the present invention, the syringe and the infusion pack as the washing water supply source 130 are referred to as a main receiving syringe 132 and a washing water pack 134. The user presses the plunger of the main receiving syringe 132, 134) to adjust the squeezing force so that the washing water of the appropriate pressure is supplied.

The rubber tube 140 has a structure in which a fluid passage is formed by connecting one end 121 of the main water receiving tube 120 protruded to the outside of the surge guide 110 and the washing water supply source 130. The rubber tube 140 is suitably flexible so that it is easy to fit the rubber tube 140 to the end of the main receiving tube 120 and the rinse water supply source 130. In addition, Should be able to do.

In addition to the basic configuration as described above, the surge guidance system 100 for dental implant treatment of the present invention can be implemented in various embodiments described below.

3 is a cross-sectional view of an embodiment connecting the main containment tube 120 to the sleeve 114 in which the main water space 116 is formed. The guide hole 112 of the surge guide 110 may be equipped with a cylindrical sleeve 114 made of a metal to reinforce the support strength of the drill. Even when the sleeve 114 is mounted, it is possible to mount the main receiving tube 120 in the structure of Fig. 2, but the embodiment as shown in Fig. 3 is also possible. An annular main water space 116 is formed between the outer circumferential surface of the sleeve 114 and the inner circumferential surface of the sleeve 114 to open the side of the tooth placement target portion 150, One end 121 can be connected to the sleeve 114. The advantage of this embodiment is that the cleansing water can be supplied to all sides of the tooth placing part 150 through the main water space 116 and the cooling effect can be improved.

4 (a) to 4 (c) show various embodiments of the shape and structure of the main receiving tube 120.

4 (a) is an embodiment in which the other end 122 of the main water receiving tube 120 forms two or more washing water jetting openings 128. For example, a plurality of washing water jetting openings 128 may be formed by pressing the middle portion of the water receiving tube 120 after exposing the other end 122 of the water receiving tube 120. When a plurality of washing water jetting openings 128 are formed, the jetting angle and range of the washing water can be designed more freely and the cooling effect of the alveolar bone receiving heat can be improved.

4 (b) shows an embodiment in which one end 121 of the main receiving tube 120 protruding out of the surge guide 110 is bent toward the incisal (front) side. When the rubber tube 140 is connected to one end 121 of the main receiving tube 120, the rubber tube 140 may interfere with the implant procedure because the position of the rubber tube 140 is on the side of the tooth placement target portion 150. In order to avoid such interference, the interference by the rubber tube 140 can be suppressed by bending one end 121 of the main receiving tube 120 toward the incisal side facing the opposite side of the tooth placement target portion 150. [

4C shows a state in which the other end 122 extending from one end 121 of the main receiving tube 120 is branched into the first branch 124 and the second branch 126, The first branch 124 and the second branch 126 extend toward the lingual and buccal sides of the tooth placement target portion 150, respectively. As shown in FIG. 4 (a), the cleaning water jetting openings 128 are formed in a plurality of (two) openings. However, a more uniform cooling effect is obtained by halfing the jetting region toward the lingual and buccal side of the tooth placement target portion 150 Which can be obtained.

 Meanwhile, FIG. 5 shows an embodiment in which the ring 118 temporarily holding the rubber tube 140 on the surge guide 110 is provided. The movement of the rubber tube 140 is more positively restricted by interposing the rubber tube 140 in the elastic ring 118. The embodiment of FIG. 5 may also be used for the purpose of reducing the inconvenience of implantation of the rubber tube 140.

Figure 6 also shows another embodiment of the rubber tube 140 utilizing the loop 118. [ The rubber tube 140 is divided into a first rubber tube 141 and a second rubber tube 142. The first rubber tube 141 is connected to one end 121 of the main receiving tube 120, 118, and the second rubber tube 142 connects the first rubber tube 141 and the washing water supply source 130 to each other. Here, the first rubber tube 141 and the second rubber tube 142 may be connected to each other by a connection nipple 144.

When a part of the rubber tube 140 is fixed to the ring 118 while being connected to the one end 121 of the main receiving tube 120 in this manner, when there are a plurality of teeth to be placed 150, The first rubber tube 141 is preliminarily provided to the part 150 and fixed to each of the rings 118 so that the user can insert the second rubber tube 141 coupled to the cleansing water supply source 130 142 is connected to the first rubber tube 141, so that the implant treatment can be efficiently performed.

Figure 7 shows another embodiment of the containment tube 120. In the embodiment of FIG. 4 (b), one end 121 of the main receiving tube 120 protruding out of the surge guide 110 is folded toward the incisor. The embodiment of FIG. 7 is more aggressively inserted into the main receiving tube 120 and the other end 122 of the main receiving tube 120 protrude along the inside of the surge guide 110. The other end 122 of the main receiving tube 120 protrudes from the center portion of the surge guide 110, And extends to the tooth placement target portion 150. The position of the one end 121 of the main receiving tube 120 connected to the rubber tube 140 or the first rubber tube 141 may be disturbed by disposing the position of the one end 121 in the distal portion far from the tooth placement target portion 150 Can be further reduced.

Here, according to the embodiment, a part of the main receiving tube 120 extending to the tooth placing part 150 along the inside of the surge guide 110 is formed as a through hole formed in the inside of the surge guide 110 It is also possible. For example, when the surge guide 110 is manufactured using a 3D printer, an empty path can be easily formed in the surge guide 110. [ Accordingly, the embodiment of FIG. 7 is configured to make a through hole extending into the to-be-placed object part 150 inside the surge guide 110, and one end 121 of the main receiving tube 120 is positioned in the incisal area So that they can be interconnected and interconnected.
