Description

Single drill dental implant set

The invention relates to a single-drill dental implant set and a method of use thereof, in particular to a single-drill dental implant set and method of use for implanting teeth immediately after tooth extraction.

Artificial tooth implants are dental implants made of titanium or zirconium dioxide implanted in the patient’s oral alveolar bone to serve as a root similar to the original tooth. After the dental implant is closely integrated with the bone, the titanium or zirconia Dentures are made on the roots of zirconium dioxide to restore the aesthetics and chewing function of the teeth. However, if the jawbone is too thin or too small, bone powder can be implanted for osteoinductive regeneration or sinus lift. Therefore, it takes a long time to make dentures after the implants and bones are tightly combined. . Secondly, the complete dental implant structure is composed of dental implants, connectors (supports) and dentures. These three can be locked by screws or fixed by connectors to replace the patient's original teeth.

Usually, when the dental implant is installed, all bone operations need to be performed to form a circular hole of the correct size in the alveolar bone for the insertion of a dental implant. Therefore, during the artificial dental implant implantation operation, surgical instruments affect the success or failure of the artificial dental implant operation and the stability of the artificial dental implant after the operation. Generally, the procedure of dental implant surgery can be divided into steps such as positioning, drilling, reaming, tapping, and implanting. When the dentist implants the dental implant, he needs to locate on the alveolar bone before drilling and cutting, drill a hole that matches the size of the dental implant, and finally screw the dental implant into the alveolar bone.

Traditionally, all holes are drilled with different drill bits, and the cut hole is drilled with a countersink until the diameter is equal to a threaded dental implant. The traditional method of drilling and cutting holes requires the use of drill bits of different sizes, which increases the operation time and difficulty. Secondly, drilling During the cutting process, great strain energy, friction energy, heat energy, etc. will be generated, causing material damage to the object being cut. According to the research of past scholars, the energy generated by the cutting process may affect the osseointegration after dental implantation.

Furthermore, if the size of the cut hole is too large, the dental implant implantation cut hole will be shaken. In order to make the dental implant stable, it is necessary to add fillers in the cut hole, which will lengthen the operation time of implanting the dental implant into the alveolar bone. . On the contrary, if the size of the cut hole is too small, a large amount of bone debris will be generated when the dental implant is implanted in the cut hole, making it difficult for the dental implant to be implanted in the cut hole, and then the elongated dental implant is implanted in the cut hole. Osseointegration healing time.

In view of the shortcomings of the aforementioned dental implant technology, the purpose of the present invention is to provide a single-drill dental implant set and method, which can directly implant dental implants into the alveolar bone, achieving the effect of shortening the working time. Secondly, it can effectively discharge the excess bone debris during the implantation process, so that the alveolar bone and the dental implant can be tightly joined to ensure that the dental implant does not shake, thereby increasing the success rate of the operation and tighter osseointegration , In order to achieve better initial stability.

To achieve the above objective, the present invention provides a single-drill dental implant set, which includes a multi-stage dental implant drill and a dental implant. The multi-stage dental implant drill bit is engaged with a dental handpiece. The multi-stage dental implant drill bit includes a rod portion, a stop portion, and a drill head. The stop portion is connected to the rod portion and the drill head. The drill head includes a diameter from A plurality of stages, at least one groove and at least one tip that taper upwards and downwards; the groove penetrates the outer surface of the drill head and extends from the bottom of the drill head to the bottom of the stop part. The dental implant includes a dental root body, a root neck and a plurality of side cut grooves. The dental root body has a fine thread part, a coarse thread part and a plurality of side cut grooves, and the fine thread part is located in the dental root body. The upper surface of the tooth base, the coarse thread part is located on the lower surface of the tooth base body; the side cuts are distributed on the coarse thread part and penetrate the outer surface of the tooth base body, and the side cut grooves are formed by the tooth base body The bottom extends to the thin The bottom of the threaded part. In addition, the root neck has an engagement hole, and the root neck is located on the top of the root body; wherein the tip of the multi-stage dental implant drill is aligned with a dental implant hole preset by the alveolar bone Position, to drill a hole and implant the dental implant; wherein the length of the fine thread portion accounts for 5% to 15% of the total length of the dental root body; the length of the coarse thread portion accounts for the total length of the dental root body 85%~95% of the total length.

In the aforementioned single-drill dental implant set of the present invention, the multi-stage dental implant drill has a drilling apex angle, the drilling apex angle is set at the top of the drill head, and the drilling apex angle is 70 degrees to 120 degrees. The point angle is an important design parameter, and its size is defined by the angle of the top of the drill bit. The drilling apex angle design will determine whether the multi-stage implant drill bit can perform stable cutting behavior at the drilling position, and has a significant impact on the reaction force and cutting energy during cutting. In a preferred embodiment of the present invention, the top angle of the drill hole is 70 degrees to 80 degrees; in another preferred embodiment, the top angle of the drill hole is 90 degrees to 118 degrees.

In the aforementioned single-drill dental implant set of the present invention, the multi-stage dental implant drill includes two grooves, and the two grooves are a first groove and a second groove, respectively, the first groove and The second groove penetrates through the outer surface of the drill head and extends from the bottom of the drill head to the bottom of the stop portion, and the second groove is opposite to the first groove.
