Description

Technical Field

[0001] This invention relates to the field of removable partial dentures, specifically to a method for designing and communicating a tooth preparation guide for removable partial dentures. Background Technology

[0002] Removable partial dentures are manufactured according to a standardized process. The overall procedure involves first obtaining an impression, pouring a plaster model, and then designing the removable partial denture on this model. The placement angle of the denture is observed and analyzed using an instrument, or computer-aided design is used to determine the placement angle and the corresponding area requiring grinding. However, a problem arises: it's unclear whether the observation and analysis should be performed by the dentist or a technician. Furthermore, the core design of partial dentures can be highly variable. Each patient has unique characteristics, and each dentist's design perspective differs, resulting in each denture being completely unique. It's rare to encounter identical cases clinically, as factors such as the design plan, the area requiring grinding, loose natural teeth, and tooth decay all play a role. Each denture may also require a different clinical approach. Due to busy schedules for dentists, or because many are general practitioners, communication regarding the design plan may be unclear, leading to low communication efficiency in removable partial denture work and impacting patient experience. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the prior art and provide a clear and efficient communication method for designing a tooth preparation guide for removable partial dentures.

[0004] This invention is achieved through the following technical solution:

[0005] A method for designing and communicating a tooth preparation guide for removable partial dentures includes the following steps:

[0006] S1: Determine the basic information of outpatients, patients, and doctors to prevent misdesign of plans among multiple outpatients or multiple patients within an outpatient clinic;

[0007] S2: Identify problems through plaster model analysis and devise corresponding solutions, including which tooth is suspected to be loose, whether to consider extraction later, or whether the upper and lower bites are too tight to repair the defect using long rings and artificial resin teeth, etc.

[0008] S3: Determine the angle, location, and amount of tooth to be removed based on the plaster model and analysis data;

[0009] S4: Design a tooth preparation guide plate to cover the plaster model using removable partial denture software;

[0010] S5: 3D printed dental preparation guide plate;

[0011] S6: Place the tooth preparation guide on the tooth to determine the angle and size of the tooth preparation.

[0012] Furthermore, in S5, 3D printing uses resin printing.

[0013] Furthermore, in S4, the thickness of the tooth preparation guide plate is 0.2mm to 1.5mm.

[0014] Furthermore, in S4, the gap between the tooth preparation guide plate and the plaster model is 0.15–0.35 mm.

[0015] Furthermore, in S4, the undercut filling angle of the tooth preparation guide is 2° to 4°.

[0016] Furthermore, in S4, all the grinding areas of the tooth preparation guide completely expose the teeth.

[0017] Compared to existing technologies, this invention determines the angle, location, and amount of tooth removal based on a plaster model and analyzed data. A tooth preparation guide, designed using removable partial denture software and 3D printed, is then applied to the plaster model. Clinically, this allows doctors to clearly understand the angle and size of the prepared teeth. This method completely solves the problem of tooth preparation for doctors; simply placing the tooth preparation guide on the teeth perfectly addresses all exposed areas, significantly saving clinical treatment time, improving clear communication, enhancing medical communication efficiency, and improving patient experience.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1 The present invention discloses a method for designing and communicating a tooth preparation guide for removable partial dentures, comprising the following steps:

[0023] S1: Determine the basic information of outpatients, patients, and doctors to prevent misdesign of plans among multiple outpatients or multiple patients within an outpatient clinic;

[0024] S2: Identify problems through plaster model analysis and devise corresponding solutions, including which tooth is suspected to be loose, whether to consider extraction later, or whether the upper and lower bites are too tight to repair the defect using long rings and artificial resin teeth, etc.

[0025] S3: Determine the angle, location, and amount of tooth to be removed based on the plaster model and analysis data;

[0026] S4: Design a tooth preparation guide plate to cover the plaster model using removable partial denture software;

[0027] S5: 3D printed dental preparation guide plate;

[0028] S6: Place the tooth preparation guide on the tooth to determine the angle and size of the tooth preparation.

[0029] By determining the angle, location, and amount of tooth removal based on the plaster model and analyzed data, a tooth preparation guide is designed and 3D printed using removable partial denture software to cover the plaster model. Clinically, this allows doctors to clearly understand the angle and size of tooth preparation. This method completely solves the doctor's tooth preparation problem. Simply placing this tooth preparation guide on the tooth can perfectly address all exposed areas, greatly saving clinical treatment time, improving clear communication, enhancing medical communication efficiency, and improving the patient experience.

[0030] In the S5, 3D printing uses resin printing and employs resin-made guides. This material allows doctors to remove teeth without worrying about damaging the guides or causing any secondary harm to the patient.

[0031] In S4, the thickness of the tooth preparation guide is 0.2mm to 1.5mm, which saves materials and improves the plasticity of the tooth preparation guide.

[0032] In S4, the gap between the tooth preparation guide plate and the plaster model is 0.15 to 0.35 mm to ensure the stability of the contact between the tooth preparation guide plate and the plaster model.

[0033] In S4, the undercut filling angle of the tooth preparation guide is 2° to 4°, making it easy to put the tooth preparation guide onto the tooth.

[0034] In S4, all the grinding areas of the tooth preparation guide fully expose the tooth, allowing the doctor to clearly see the angle and size of the tooth preparation in clinical practice.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
