Description

Construction of drilling template and its calibration method based on implant path planning, and How to configure the integrated dental implant guide kit

The present invention provides a drilling template construction and calibration method based on dental implant path planning, and an integrated dental implant guide set configuration method, especially a method that can combine oral tomographic images and three-dimensional oral images based on tooth shape information. Combine to form a digital model of the oral cavity, so that the relative relationship between the tooth type information, alveolar bone type information and gum type information can be presented, and the implant drilling path can be accurately planned, and the corresponding drilling template can be constructed. When constructing the implant guide plate by drilling holes in the dental model, and subsequently drilling the patient’s gums through the implant guide plate, the drilling path can completely correspond to the planned implant drilling path, so as to improve The accuracy of dental implant surgery.

Press, dental implant (Dental implant) is through the installation of artificial tooth roots to form dentures, so as to make up for the restorative technology of missing teeth; The root of the natural tooth is used as the foundation of the crown, and after the alveolar bone is combined with the implant, the artificial crown can be installed on the implant, so that it can form a natural tooth and have a natural tooth Compared with the conventional bridge and dentures, the dentures formed by dental implants are more beautiful and comfortable, and can be used for a long time, so it is one of the main methods for the restoration of missing teeth.

In order to improve the accuracy and aesthetics of dental implants, it is usually through oral scanning machines or tomographic scans, so that the computer can design the position of the implant and then output it to form a guide plate, so that the drill can be guided by the guide plate to drill the preset position. The depth is set so that the implant can be installed at the desired position; however, in the current clinic, the chair-side guide is made directly on the tooth model, and after the operator plans the desired implant position, it is directly placed on the tooth. Drill a hole, install a positioning post through the hole, and fit a set around the periphery of the positioning set, and a fastener is set on one side of the set, and the surrounding teeth are covered with photosensitive resin, and the set and fastener are bonded at the same time Afterwards, it is cured by light, and finally a guide element is assembled to the fastener by removing the positioning column and the kit to form a guide plate; however, for the process of drilling holes in the tooth mold, the drilling path will determine the subsequent The position and angle of the implant, because the tooth model only shows the shape of the mouth, and the planning of the drilling path mainly depends on the occlusal relationship between the teeth, because the shape of the bone cannot be known from the tooth model state, and there is soft tissue (gum) outside the bone, and the thickness of the gum is different for each person, and even the thickness of the gum is different for different parts of the same person. It is recommended to cut or open the gum, so that the doctor can directly see the bone under the gum, so as to facilitate subsequent dental implants; however, it will cause discomfort to the patient and delay the operation schedule. In the position and angle of the drill hole, if the bone condition is found to be poor and the dental implant cannot be performed, the subsequent procedures cannot be carried out, and because the operating space of the oral cavity is limited, it is difficult to directly change to the correct dental implant position based on the operation experience ; Therefore, the planning of the drilling path is an extremely important part of the pre-implantation operation. If it is not accurately planned, judged or calibrated, there will be doubts that will affect the subsequent implantation process.

In addition, the setting of the existing dental implant guide kits is usually a two-piece set with the kit and the positioning post separated, so that the positioning post can be inserted into the drilled tooth mold by passing the positioning post behind the kit. The hole is used to adjust the direction and position of the set, and then cover the surrounding teeth with photosensitive resin, and at the same time, the bonding set is cured by light, so that the positioning post is removed to form a guide plate; however, the configuration of the implant guide set is passed through When the photosensitive resin is bonded, it is often due to the limited strength of the combination between the positioning column and the kit, which causes shaking or displacement during the bonding process, so that great attention must be paid during the process, or it needs to be pressed and fixed by fingers, which will make the production process very difficult. It is inconvenient, and it is very easy to cause the angle of the set to be lower than the expected plan due to the deviation, resulting in the inability to accurately drill the holes in the subsequent implant drilling, making the implant have doubts about deviation.

In view of this, our inventors are concentrating on further research on the accuracy of dental implant path planning, and subsequent operations can be performed accurately according to the planned path, and started to develop and improve, hoping to solve the above problems with a better invention , and after continuous testing and modification, the present invention has come out.
