[0002] Dental implant refers to a method of restoring missing teeth that uses a lower structure implanted in bone tissue to support and retain the upper dental restoration. It consists of two parts: a lower supporting seed and an upper dental restoration. The lower supporting seed is made of artificial materials and is surgically implanted into the tissue to obtain firm retention support from the bone tissue. It is connected to the upper dental restoration through special devices and methods.

[0003] In the prior art, when implanting a denture, it is necessary to first drill a hole in the gum, then embed the implant into the gum, and then connect the implant base inside the implant. However, the shape of the alveolar bone around the hole is irregular. When the bottom of the implant base is connected to the implant, the implant base will be supported by the irregular alveolar bone around the hole, resulting in a gap between the implant and the implant base. The gap is prone to bacterial growth and will affect the health of the gums. Utility Model Content

[0008] A cutting assembly, wherein a connecting shaft for connecting to an electric drill is disposed on the upper side of the positioning bolt, and the cutting assembly is disposed on the lower side of the connecting shaft for trimming a bone hole in the gums that matches the implant base;

[0009] And a control component used in conjunction with the cutting component, wherein the control component is arranged on the upper side of the positioning bolt and is used to control the depth of the bone hole.

[0010] In a possible design, the cutting assembly includes a rotating blade fixed to one end of the connecting shaft close to the positioning bolt, and a matching groove is formed at the bottom end of the rotating blade.

[0011] In a possible design, the rotating blade has four widths, namely 4.0 mm, 4.5 mm, 5 mm and 5.5 mm. The four widths of the rotating blade are used to control the radius of the bone hole.

[0012] In a possible design, the control assembly includes a positioning step fixed to the top of the positioning bolt for limiting the rotating blade, and a guide hole matching the matching groove is fixed to the top of the positioning step.

[0013] In a possible design, the thickness of the positioning step may be 0.5 mm or 1.5 mm for adjusting the depth of the bone hole.

[0014] In a possible design, the rotating blade is made of cemented carbide.

[0015] In the present application, after the positioning bolt is installed in the implant, the rotating blade is sleeved on the surface of the guide hole, a suitable rotating blade and an electric drill are selected for connection, the electric drill is started to drive the connecting shaft to rotate, and the rotation of the connecting shaft drives the rotating blade to rotate. The rotating blade is limited by the guide hole, and the rotating blade rotates to cut the alveolar bone protruding from the implant to form a bone hole for accommodating the implant base. When the bottom end of the rotating blade contacts the top of the positioning step, drilling is stopped and the bone hole is formed. At this time, the implant base is installed, and there is no alveolar bone protrusion between the implant base and the positioning step.

[0016] Beneficial Effects

[0017] In the utility model, by adopting a rotary blade made of cemented carbide and a precise control component design, the invention can achieve high-precision trimming of the bone hole. This can not only ensure good integration of the implant and the surrounding tissue, but also improve the stability and service life of the implant;

[0018] The utility model can improve the trimming accuracy and efficiency, reduce the damage to the patient's oral tissue and the operation time, thereby reducing the patient's pain and discomfort.

[0019] In the utility model, the gap between the implant and the implant base is eliminated, so that the installation of the implant base is more firm. BRIEF DESCRIPTION OF THE DRAWINGS
