Description

Implant implant guide assembly

This creation is about a guide assembly.

Implantation is the implantation of implants (such as titanium artificial roots) into the alveolar bone of the teeth as a substitute for the original roots of the teeth. After the implants are tightly bonded to the bones, the dentures are attached to the implants to restore The patient has a beautiful appearance and a chewing function.

Although dental implant surgery is less risky than other types of surgery, in order to avoid accidental injury to other important tissues, such as nerves, blood vessels and roots of adjacent teeth, as well as to ensure the aesthetics and occlusion of patients after surgery, in addition to preoperative Planning must be carried out cautiously. In the operation, it is necessary to use good auxiliary equipment to ensure the safety of the patient during the operation and after the operation.

In general, preoperative planning is based on the shape of the tooth itself and its geometric relationship with important tissues to further determine the orientation of the implant, such as angle and depth, and make dental implant holes according to the planning results. The guide plate allows the surgery to be reliably implemented according to the planning results. FIG. 1 is a schematic view of a guide plate for a conventional dental implant hole, which is shown in FIG. The guiding plate 1 is formed according to the oral structure of the patient, that is, the corresponding orientation of the teeth and the bone, and the guiding plate 1 has a metal ring 11, and the metal ring 11 is based on the position, angle and implantation of the implant. The parameters such as depth are set on the guiding plate 1, and the inner space 111 of the metal ring 11 can be sleeved by the instrument. During the implant surgery, the instruments used and implanted implants are made of metal rings 11 and their rings. The inner space 111 is guided to reach a predetermined position.

However, in the process of implanting a single hole, the steps of drilling and reaming into the implant must use several instruments with different outer diameters. In contrast, the inner diameter of the metal ring 11 is fixed, so it often occurs. Some of the instruments cannot be fitted with the metal ring 11 because the outer diameter is too large or too small, which leads to the inability to accurately guide the situation, which affects the safety of the patient. Especially when drilling, reaming or implanting, the orientation is not accurate, which will affect the future chewing and occlusion of the patient and the overall aesthetics.

Therefore, how to design a guiding assembly for planting dental implants, which has the function of assisting and transferring, so that the different outer diameters of various instruments can be properly matched with the single inner diameter of the metal ring of the guiding plate, so that the physician It is one of the most important topics in the field of implants to perform dental implant surgery based on the planned results safely and accurately.

In view of the above problems, the purpose of the present invention is to provide a guiding assembly for planting dental implants, which has the functions of assisting and transferring, so that different outer diameters of various instruments can be properly combined with the metal ring of the guiding plate. The inner diameter fit allows the physician to perform dental implant surgery safely and accurately based on the planned results.

In order to achieve the above object, according to one of the creations, the dental implant guiding assembly is used in combination with a guiding plate having at least one metal ring, and the implant guiding device comprises an open clamping And a replacement guide. The opening clamp comprises a hand piece and a body. The body is connected to the hand-held portion and has a pivot and two clamping portions, and the pivot pivotally connects the clamping portions. The replacement guide has a guiding portion and a connecting portion. The guiding portion is for arranging a metal ring, and the connecting portion is for sandwiching between the clamping portions.

In one embodiment of the present invention, the body has a scissors-like configuration.

In an embodiment of the present invention, each of the clamping portions has a clamping head and a clamping handle, and the clamping head and the clamping handle have a predetermined angle.

In one embodiment of the present creation, the predetermined angle is from 120 degrees to 160 degrees.

In an embodiment of the present invention, one of the clamping portions has a recess, and the other has a fastener that engages the fastener.

In one embodiment of the present invention, the recess has an opening having a smaller inner diameter.

In one embodiment of the present invention, the outer diameter of the handpiece is larger than the body.

In an embodiment of the present invention, the replacement guide has an intermediate portion, and the guiding portion and the connecting portion are respectively disposed at opposite ends of the intermediate portion.
