Description

TECHNICAL FIELD

[0001] The utility model relates to a dental implant equipment technical field, and specifically refers to a kind of abutment guiding drill. BACKGROUND

[0002] The tooth loss rate of middle-aged and old people is very common, and the average number of remaining teeth in the 65-74 age group is 20.97 / 32. With the increase in per capita disposable income, oral implantation repair is in a rapid development stage and has become the primary repair method for tooth loss in the middle-aged and old. Among people aged 65-74, 86% have tooth loss, 4.5% have no teeth in their mouths, and 63.2% have had dental prosthetics.

[0003] Implant teeth can achieve a repair effect similar to the function, structure and aesthetic effect of natural teeth, and have become the preferred repair method for an increasing number of edentulous patients. Implant teeth refer to a dental repair method that supports and retains the upper dental prosthesis with the lower structure implanted in the bone tissue; it is a surgical procedure that implants a pure titanium metal with high compatibility with human bone into the alveolar bone of the edentulous area after precise design to form a cylindrical or other shape similar to a tooth root. From preparing the implant socket to implanting the implant, and finally after 1-3 months according to the bone integration in the oral cavity, the previous covering screw is removed, the abutment is installed, and a full ceramic or porcelain tooth crown is made on the artificial tooth root, which completes the oral implantation. Due to differences in the shape of each person's alveolar bone, the position of the implant tooth is different, and there are large differences in the alveolar bone, or irregular growth of the alveolar bone. During the implant surgery, before the abutment is installed after the implant is implanted, the abutment guiding drill is used to remove the alveolar bone or gum around the upper part of the implant.

[0004] At present, the structure and size of the abutment guiding drill are not reasonable, and when in use, it is not easy to probe into the inner wall of the implant without flap of the gum, which is not conducive to grinding the alveolar bone and gum that block the way; the guide rod enters the implant, and rotates during work, which may damage the implant. UTILITY MODEL CONTENTS

[0005] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technology, and to provide an abutment guiding drill.

[0006] To solve the above technical problems, the technical scheme provided by the utility model is an abutment guiding drill: including a handle, a drill bit, and a guide rod;

[0007] One end of the handle is provided with a connecting part, the other end of the handle is connected with the drill bit and is integrally formed, and one end of the guide rod is rotatably connected with the other end of the drill bit;

[0008] The guiding rod comprises a main body part and a base part, the main body part has a diameter of 1.2 mm and a length of 4 mm, the base part has a diameter of 2.5 mm at one end and 1.2 mm at the other end, and a length of 1 mm, and the distal end of the main body part is inversely curved;

[0009] The distance between the base part and the drill bit is 0.1 mm;

[0010] The drill bit is provided with 10 cutting edges, and the length of the drill bit is 6 mm.

[0011] Compared with the prior art, the utility model has the advantages that the utility model is used for removing the alveolar bone or gum around the upper part of the implant before the abutment is installed after the implant is implanted, the 5mm guiding rod is easier to probe into the inner wall of the implant without flap, then the guiding rod is deeply inserted along the inner wall of the implant, the drill bit is ground to remove the alveolar bone and gum, the guiding rod and the drill bit are movably connected, the guiding rod is inserted into the implant, the drill bit is rotated, at this time, the guiding rod does not rotate, and the implant is not damaged, the 6mm long drill bit can remove the alveolar bone around the abutment and trim the gum around the abutment, the 1.2mm diameter guiding rod has a 1.1-1.3mm gap in the implant, so that the drill bit has more space to remove the surrounding tissue, the 5mm long guiding rod is easier to slide into the implant in the thick gum type soft tissue, the base of the guiding rod is designed as an inclined surface, when the guiding rod is deeply inserted into the implant to the neck edge of the implant, the inclined surface of the guiding rod guides the abutment drill bit to the center position to match, and the 0.1mm gap between the base and the drill bit can avoid damaging the implant during cutting.
