Description

Technical Field

[0001] The present invention relates to the technical field of dental implant guide plates, and in particular to a 3D dental implant guide plate body and a manufacturing method thereof. Background Art

[0002] Dental implants are an effective method for treating tooth loss. During the implantation process, a dental implant guide is needed to guide the precise implantation position of the implant. Traditional dental implant guides are handmade with low precision, which can easily lead to implant position deviation and affect the success rate of implant implantation.

[0003] In order to improve the accuracy of dental implant guides, 3D dental implant guides have appeared in recent years. 3D dental implant guides use three-dimensional scanning technology to collect patient oral data, then use computer software to design the guides, and finally use 3D printing technology to make the guides. 3D dental implant guides have the following advantages: high data acquisition accuracy, which can accurately reflect the patient's oral condition; high guide design accuracy, which can accurately determine the position, depth and angle of the implant; high guide manufacturing accuracy, which can ensure the fit between the guide and the patient's mouth;

[0004] Some traditional dental guide fixation methods may rely on simple clamping or adsorption for fixation. Due to the complex internal environment of the patient's oral cavity, the milling cutter will generate certain impact force and vibration during operation. If the dental guide cannot be firmly fixed in the predetermined position, it is easy to be displaced under the action of these external forces. Once displacement occurs, it will not only affect the position accuracy of the implantation, but may also cause damage to the surrounding teeth and tissues. Therefore, a 3D implant dental guide body and a manufacturing method thereof are proposed to address the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a 3D dental implant guide body and a method for manufacturing the same, so as to solve the problem that a milling cutter will generate certain impact force and vibration during operation. If the dental guide cannot be firmly fixed in a predetermined position, it is easy to be displaced under the action of these external forces. Once displacement occurs, it will not only affect the position accuracy of the implantation, but may also cause damage to the surrounding teeth and tissues.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0012] As a further optimization of the present invention, wherein: S1: Collecting patient oral data: When collecting patient oral data, the following points need to be noted:

[0013] Ensure the accuracy and completeness of the data. The accuracy and completeness of the data are the basis of the guide plate accuracy. When collecting data, a high-precision oral scanner or CBCT equipment should be used to ensure the integrity of the data. When collecting data, care should be taken to avoid important structures such as nerves, which are located in the alveolar bone.

[0014] S2: Designing the guide: When designing the guide, the following points should be noted:

[0015] Accurately determine the position, depth and angle of the implant. The position, depth and angle of the implant are the key to the accuracy and success rate of the guide. When designing the guide, the position, depth and angle of the implant should be accurately determined according to the patient's oral condition, and the operating space during the implant placement should be considered. During the implant placement process, a certain amount of operating space is required.

[0022] Use the calibrator: Install the guide plate on the calibrator and take measurements;

[0023] Using implants: Install the guide plate on the implants and perform implantation;

[0024] S5: Use a guide to place an implant: During implant placement, the following points should be noted:

[0026] Be careful not to damage the guide: During the implant placement process, be careful not to damage the guide;

[0027] As a further optimization of the present invention, the accuracy of the guide plate can be expressed by the following formula:

[0028] Accuracy = actual position - expected position

[0029] The actual position is the position where the implant is actually implanted, and the predetermined position is the position marked on the guide plate.

[0030] As a further optimization of the present invention, the implantation success rate can be expressed by the following formula:

[0031] Success rate = number of successfully implanted implants / total number of implants implanted

[0032] Among them, the number of successfully implanted implants refers to the number of implants that can be successfully fused after implantation, and the total number of implanted implants refers to the number of all implants implanted.

[0034] 1. In the present invention, by providing the dental guide body, the positioning mechanism and the rubber soft plate, the dental guide body and the tooth root can be stably attached together during use, which can effectively solve the problem of displacement of the dental guide during use and during the entry of the milling cutter, and further ensure the problem of later implant deviation;

[0035] 2. In the present invention, the soft plate body and the semi-cylinder can further improve the protective effect when the tooth guide body contacts the tooth root, and can improve the comfort during the installation process. At the same time, the telescopic spring and the prompt column can prevent the adjustment force from being too large, which may cause damage to the user's tooth root;

[0036] 3. In the present invention, a 3D dental implant guide with high precision and high success rate can be produced through the method for producing the dental guide body, and the quality of the production can be later verified through the verification formula of the guide accuracy and the implant success rate, which is safer and more accurate;

[0037] 4. In the present invention, the spring telescopic rod can make the semi-cylinder adaptively adjusted according to the shape and pressure of the tooth root, thereby improving the fit between the rubber soft plate and the tooth root, ensuring better contact tightness, reducing the occurrence of sliding, and improving the stability of the tooth guide body. At the same time, when the rubber soft plate is under pressure, the compression of the spring telescopic rod can play a buffering role, reduce the impact force on the tooth root, and protect the tooth root from excessive pressure damage.
