Description

Dentist replaceable bone drilling positioning guide

The present invention relates to a positioning guide, and more particularly to a replaceable bone drilling positioning guide for a dentist.

A tooth is a calcified tissue used to chew food. When an adult's teeth are damaged by oral diseases or external forces, it cannot be regenerated. After the tooth is damaged, the alveolar bone and gums may shrink and the feeding function is affected. In the case of dentures, which have often replaced damaged teeth, the most common treatment today is manual implants.

When the teeth are damaged or removed, the general treatment method is to install dentures instead of the original real teeth. The current common method of installing dentures is to use fixed artificial implants. The fixed artificial implant is to first drill a proper size cavity in the proper place of the gum in the patient's mouth, and then implant an artificial root in the cavity and suture the wound, and the artificial tooth is rooted on the dental bone. After being completely long together, the abutment teeth with screws are locked on the artificial roots, and artificial prostheses are finally placed on the teeth of the abutments. The artificial root and the abutment tooth with the screw can support the artificial tooth completely by the gum bone, thereby enabling the artificial tooth to withstand the bite force of the upper and lower teeth, and achieve the purpose of restoring the bite function of the tooth.

A drilling assisting device that can be used to assist in drilling a cavity in a dental bed bone, such as the new patent application No. M498344 of the Republic of China, "Drilling Positioning Aid Device for Dental Implants", please refer to FIG. A hollow semi-cylindrical positioning device 90 is embedded and the positioning device 90 is buried to guide the mold to facilitate drilling of a drill rod on the gum bed. Wherein the positioning device 90 has a base 91 and At least one guiding member 92 abutting against the base 91, and adjusting the size of the drilling hole by increasing or decreasing the number of the at least one guiding member 92. Although the positioning device 90 has a hollow semi-cylindrical design that allows the drill rod to facilitate entry into the positioning device 90 in a limited oral space, this design also greatly increases the instability during drilling, which is easily due to the lack of a drill pipe. Supporting the wall surface causes displacement of the drill pipe. In addition, when the drill rod is moved toward the moving hole in the long axis direction of the base 91, since the at least one guiding member 92 is not tightly coupled with the base 91, the at least one guiding member 92 is easy to The drill pipe moves at the same time, causing great trouble in operation.

In view of this, it is necessary to develop the prior art to improve the drilling of the drill pipe and to stabilize the guide member with the positioning device.

In order to overcome the shortcomings of the prior art, it is an object of the present invention to provide a bone drilling positioning guide capable of supporting stable drilling of a drill pipe while being firmly coupled with the guiding piece.

In a further preferred embodiment, the at least one first groove 16 is two oppositely disposed first grooves 16 , and the at least one second groove 17 is two oppositely disposed second grooves 17 , the at least one protrusion The portion 25 is a pair of convex portions 25 that are oppositely disposed, and each of the convex portions 25 is detachably coupled to each of the first concave grooves 16 or the second concave grooves 17 of the base 10. The second outer wall surface 21 is detachably attached to the first inner wall surface 14 of the base 10.

The positioning block 30 is formed on the first outer wall surface 13 of the base 10, and the positioning block 30 has opposite sides, wherein one side is connected with the first outer wall surface 13 of the base 10; The width of the block 30 in a cross section perpendicular to the longitudinal direction of the base 10 is tapered from a side away from the first outer wall surface 13 toward a side connected to the first outer wall surface 13 to have a dovetail shape.

Referring to FIG. 5, the difference between the second preferred embodiment of the present invention and the first preferred embodiment is that the base 10A further includes two oppositely disposed protruding members 19A, and the protruding members 19A are protruded from The first outer wall surface 13A is adjacent to the two side edges 141A of the first inner wall surface 14A, respectively, and the convex members 19A extend away from each other; in a preferred embodiment, the convex members 19A are It is in the form of a sheet or a long block and is adjacent to the top end 11A of the base 10A.

Referring to FIG. 2 and FIG. 4, in the first preferred embodiment of the present invention, the pedestal 10 and the positioning block 30 of the disposable bone drilling positioning guide device of the dentist of the present invention are first buried. And a guiding mold for simulating the arrangement of the teeth of the patient, and then the two convex portions 25 of the guiding member 20 are respectively inserted from the first notches 161 of the two first grooves 16 of the base 10, when the convex portions 25 are After the first abutting faces 162 are abutted, they are further moved toward the respective second grooves 17, so that the second outer wall surface 21 is in contact with the first inner wall surface 14 of the base 10. The first concave groove 16 of the base 10 and the second concave grooves 17 are slidably engaged with the convex portions 25 of the guiding member 20, so that a drill rod is second to the guiding member 20. When the guiding groove 23 is bored toward the longitudinal direction of the guiding member 20, the guiding member 20 does not move simultaneously with the drill rod. When you want to change When the second inner wall surface 22 has a diameter d2 of the guide member 20, it is only necessary to push the second outer wall surface 21 of the guide member 20 from the recess 18 of the base 10 to move the guide member 20 from the second recessed groove 17 to The first recesses 16 simultaneously move the second outer wall surface 21 away from the first inner wall surface 14, and then pull the convex portions 25 away from the first notch 161, and then the other guide member 20 The step of inserting and engaging with the susceptor 10 completes the swapping operation.

Referring to FIG. 4 and FIG. 6 , the drill rod enters the second guiding groove 23 from between the two extending portions 24 of the guiding member 20 , and then follows the second guiding groove 23 . The guide member 20 is drilled in the long axis direction. Since the distance d1 between the extensions 24 is smaller than the diameter d2 of the second inner wall surface 22, in addition to the advantage of allowing the drill rod to facilitate access to the second guide groove 23 in a limited oral space, When the drill rod is drilled, it is not easy to deviate from the second guiding groove 23, and the drill rod is also not easily displaced toward the extending portion 24 to increase the stability and precision during drilling.

Referring to FIG. 5 and FIG. 7 , in the second preferred embodiment of the present invention, the pedestal 10A and the positioning block 30A of the disposable bone drilling positioning guide device of the dentist of the present invention are first buried. Into a guiding mold simulating the arrangement of the teeth of the patient, when the patient needs to implant two adjacent teeth, calculate the distance of the teeth and select the convex members 19A of the appropriate length, by embossing the adjacent two bases 10A After the pieces 19A are in contact with each other at an end away from the first outer wall surface 13A, the dental bone drilling positioning guide device is embedded in the guiding mold to reduce the inconvenience and lifting of the multiple measurement. The effect of efficiency.

It is apparent to those skilled in the art that various modifications and variations can be made without departing from the scope and spirit of the invention. Although the present invention has been described in terms of specific preferred embodiments, it should be understood that the invention should not be In fact, the various modifications that are apparent to those skilled in the art are also contemplated by the scope of the invention.
