Description

Measuring device for implant position and method thereof

The present invention relates to a position measuring device for a dental implant, and more particularly to a dental implant position measuring device having an artificial root size that can be measured.

When a person's teeth are broken, detached, or removed due to severe tooth decay, artificial dental implant surgery must be performed to implant the artificial root and then install dentures to maintain the integrity and health of the teeth.

Conventional dental implant surgery is to drill a hole down the gum in the part of the patient's missing tooth, and then fix the artificial artificial root into the hole to fix it. In this way, it is difficult to control the accuracy of the drilling position by the physician's experience or self-determination to drill the position of the artificial root to be implanted and the size of the artificial root, so that the drilling position is easily displaced during the process, or The artificial roots are not the same size, so the implanted artificial roots may be skewed or poorly fixed, and severe cases may lead to dental implant failure.

Please refer to the first figure, which is a schematic diagram of a conventional dental implant position measuring device. The physician uses a position measuring device 110 to measure the position of the missing tooth of the patient, thereby determining the distance D between the teeth on the two sides of the position, and the The position measuring device 110 has a plurality of measuring holes 111. When the width of the missing tooth position is measured, the width corresponds to one of the measuring holes, and the measuring hole is located at the center of the missing tooth position, and the physician will according to the amount. The hole is drilled into the patient.

The physician first destroys the superficial cortical bone with a Round drill and reams or drills the alveolar bone with a Twist drill, and then implants the implant into the alveolar bone of the patient. After the implant and the alveolar bone are completely adhered, the prefabricated denture is attached to the implant to fix the entire dental implant procedure.

However, for the selection of artificial roots, the size is determined by the doctor based on experience or self-determination. The dimensional accuracy may be wrong due to human factors, resulting in the wrong size of the artificial root used, such as the artificial root size may be too large. The hole cannot be placed, and the artificial root size is too small, which may result in a poor fixation state, which may lead to failure of the implant operation.

Furthermore, the above-mentioned conventional dental implant position measuring device needs to be hand-measured and drilled, and the patient's oral space is limited, and the measuring instrument and the drilling device are placed in the patient's mouth, and the space is easy to cause the physician's sight. Bad problems, which in turn increase the risk of surgery.

In the above-mentioned surgical procedure, the doctor needs to perform the measurement first, and then perform the drilling procedure. The number and types of surgical instruments used are large, and the corresponding surgical instruments must be replaced between each procedure, so that each The conversion between programs makes it easy to select inappropriate surgical instruments, increase the complexity of the surgical procedure and is more time consuming, and the measuring instruments and surgical instruments are repeatedly used after high temperature sterilization, and the probability of bacterial infection is also increased.

Based on the above-mentioned deficiencies, the present invention provides a measuring device for the position of the implanting tooth, and the measuring device determines the position of the dental implant drilling hole, the distance between the natural teeth and the size of the artificial tooth root, thereby assisting the doctor to accurately perform the proper position. Dental implants can also effectively reduce the number of procedures and surgical instruments used by physicians, reduce the number of oral surgical instruments, cause poor vision of the physician, avoid the error between the program conversion and the possibility of bacterial infection, and improve the above multiple The procedure is such that the procedure for measuring distance, drilling position and root size can be completed at one time.

The invention provides a measuring device for the position of the implant, the measuring device comprises a sleeve, the sleeve is a hollow cone, and is sleeved on the shank, the shank has a drill bit, and the hollow cone has a smaller diameter. A drill bit adjacent to the shank at one end, and the hollow cone is further defined as a plurality of sized blocks, each sized block corresponding to a color, a graphic or a symbol.

The plurality of size blocks on the sleeve can represent the size of the artificial root. Therefore, when the measuring device is placed in the missing position of the patient, the width of the missing tooth position will correspond to one of the size blocks on the sleeve, and each size area The blocks have obvious distinguishable features, so the user can immediately know the size of the artificial root through visual inspection. In addition, the size of the artificial root is first placed by the size block, and then the arrangement of the teeth on the second side of the missing position is compared. Immediately, the position of the hole can be appropriately drilled, or the distance between the teeth on both sides of the missing tooth position and the distance between the axis of the drilled hole and the position of the missing tooth can be measured immediately.

The dental implant position measuring device of the invention is sleeved on the drill handle, instead of the traditional physician first measuring the position of the missing tooth by using the position measuring device, and then determining the artificial root size by experience or self-determination. The dental implant position measuring device provided by the invention can reduce the error caused by human factors, increase the accuracy of the doctor to determine the artificial root size, and accurately locate the center position of the missing tooth position, thereby reducing the procedure and surgical instruments of the physician. The number, while improving the success rate of implants.
