Description

Technical Field

[0001] The invention relates to the field of oral medicine teaching, and in particular to a complete denture functional impression training system and method thereof. Background Art

[0002] Functional impression of full denture is one of the basic operation skills that dentists must master. Full denture is a common restorative technology used in patients with complete edentulous jaws. Since the alveolar bone will undergo personalized absorption after all teeth are lost, dentists must obtain the personalized alveolar mucosal conditions of elderly patients through functional impressions, and then make a full denture that adapts to the personalized oral and maxillofacial muscle system of the patient. Therefore, dentistry students must undergo a large amount of full-mouth functional impression training in vitro to improve their full-mouth denture treatment level. Only after passing the assessment can they perform good full-mouth denture restoration for elderly edentulous jaw patients in vivo.

[0003] At present, the full denture impression training of dental students is mainly carried out on the simulation head model, using the standard edentulous jaw model. Although it can improve the students' full denture impression level to a certain extent, the students currently mainly make edentulous jaw anatomical impressions, without functional impressions of the oral and maxillary system, such as no buffering training for the lip and cheek frenulum, no pressure impression training for the posterior bank closure area, and no buffering training for the maxillary tuberosity and the internal oblique ridge. These functional trainings are closely related to the restoration effect of full dentures in clinical practice. Regarding the current training methods, students generally reflect that laboratory impressions are too simple, but when facing edentulous patients in the clinic, they reflect that functional impressions are very difficult to operate.

[0004] On the other hand, the current evaluation of full-mouth impressions is mainly conducted face-to-face by teachers, which takes up the teacher's time and it is impossible for the teacher to see the impression operation techniques of each student, so it is relatively subjective. Correspondingly, it is impossible to give personalized corrective measures based on the student's results. Summary of the invention

[0005] In view of the problems in the prior art, the present invention first provides a simulation head model for full denture functional impression training, the simulation head model includes a maxillary model and a mandibular model, the maxillary model and the mandibular model are both provided with a plurality of pressure sensing devices, and the pressure sensing devices are arranged in the pressure sensing area and the traction sensing area during functional impression.

[0006] Furthermore, the pressure sensing area includes the maxillary vestibule groove distribution area and the posterior bank area of ​​the maxillary model, and the mandibular vestibule groove and the lingual floor of mouth distribution area and the inner oblique ridge area of ​​the mandibular model.

[0007] Furthermore, the traction sensing area includes the lip and cheek frenulum area of ​​the maxillary model and the lip and cheek frenulum area of ​​the mandibular model.

[0008] The present invention also provides a method for full denture functional impression training, using the above-mentioned simulation head model, the method comprising:

[0009] According to the requirements of the functional impression, the sensing rules of the pressure sensing area and the stretch sensing area are set;

[0010] When the simulation head mold is used for functional stamping, the pressure signals of the pressure sensing devices in the pressure sensing area and the pull sensing area are monitored to determine whether the stamping operation complies with the sensing rules.

[0011] Furthermore, the sensing rules of the pressure sensing area include:

[0012] By determining whether the corresponding pressure sensing device in the pressure sensing area senses a pressure signal, whether the range requirement for obtaining the impression is met;

[0013] By comparing the pressure signal of the corresponding pressure sensing device in the pressure sensing area with the preset pressure threshold, it is determined whether the corresponding position meets the pressure size requirement of the stamp.

[0014] Furthermore, the sensing rules of the pulling sensing area include:

[0015] Whether the pulling operation is implemented is determined by determining whether the amplitude of the pressure signal reduction of the corresponding pressure sensing device in the pulling sensing area within a preset time interval is greater than a preset pressure difference.

[0016] Furthermore, a virtual image of the simulated head model is created, and the representation of the pressure signal of the pressure sensing device is displayed in real time on the virtual image.

[0017] The present invention also provides a device for full denture functional impression training, the device comprising:

[0018] Processor; and

[0037] In the description of the embodiments of the present invention, “plurality” means two or more, unless otherwise clearly and specifically defined.

[0038] Figure 1 A schematic diagram of a full denture functional impression training system according to an embodiment of the present invention is shown, which includes a simulation head model 100 and a monitoring terminal 200 .

[0039] The simulation head model 100 includes a maxillary model 110 and a mandibular model 120. Both the maxillary model 110 and the mandibular model 120 are provided with a plurality of pressure sensing devices, which are arranged in corresponding areas where the operator is required to press and pull the maxillary model 100 and the mandibular model 120 when using the simulation head model 100 for functional impression training. That is, according to the training requirements, the pressure sensing area and the pulling sensing area are defined in the maxillary model 110 and the mandibular model 120, and the above-mentioned pressure sensing devices are arranged in the pressure sensing area and the pulling sensing area.

[0040] The pressure sensing device may be installed in the maxillary model 110 and the mandibular model 120 by being embedded in a corresponding position on the surface of the maxillary model 110 and the mandibular model 120, or by being covered at a corresponding position under the surface of the maxillary model 110 and the mandibular model 120. Figure 2 and 3 The above two installation methods are shown as examples, wherein: Figure 2 The pressure sensing device 130 is disposed in a groove on the surface of the mandibular model 120. Figure 3 The surface of the mandibular model 120 is a double-layer structure, and an installation cavity is defined between the double-layer structure, and the pressure sensing device 130 is arranged between the above-mentioned installation cavity. There are many existing technologies for the installation of pressure sensing devices in oral models or dental pads, which are not the focus of the present invention and will not be elaborated here. As for the type of pressure sensing device, various existing pressure sensors can be used, such as piezoelectric pressure sensors, piezoresistive pressure sensors, capacitive pressure sensors, electromagnetic pressure sensors, etc., without limitation.

[0041] Figure 4 The pressure sensing area and the tension sensing area of ​​the maxillary model 110 are shown, including:

[0042] The area where the black line is located corresponds to the distribution area of ​​the maxillary vestibule groove and is the range that must be obtained when taking a full denture impression. Therefore, this area is defined as the pressure sensing area, and several pressure sensing devices can be set along the black line;

[0043] The position indicated by the red arrow is the lip-cheek frenulum area of ​​the maxilla, which needs to be pulled during clinical operation, so this position is defined as the pulling sensing area, and one or multiple dense pressure sensing devices can be set at this position;

[0044] The yellow area is the posterior dyke area, which should be pressure impressed during clinical operation, so that the area is defined as the pressure sensing area, and several pressure sensing devices can be distributed in the area.

[0045] Figure 5 The pressure sensing area and the tension sensing area of ​​the mandibular model 120 are shown, including:

[0046] The area where the black line is located corresponds to the mandibular vestibule groove and the lingual floor of the mouth. It is the range that must be obtained when taking a full denture impression. Therefore, this area is defined as the pressure sensing area, and several pressure sensing devices can be set along the black line.

[0047] The position indicated by the red arrow is the lip-cheek frenulum area of ​​the mandible, which needs to be pulled during clinical operation, so this position is defined as the pulling sensing area, and one or multiple dense pressure sensing devices can be set at this position;

[0048] The green area is the medial oblique ridge area. The anatomical structure is a bone protrusion. Clinically, buffering is required, but there is still a small amount of pressure. Therefore, this area is defined as a pressure sensing area, and several pressure sensing devices can be distributed in this area.

[0049] In combination with the above-mentioned simulation head model 100, the method for full denture functional impression training is described in detail below. The method for full denture functional impression training of this embodiment includes:

[0050] According to the requirements of the functional impression, the sensing rules of the pressure sensing area and the stretch sensing area are set;

[0051] When the simulation head model is used for functional impression, the pressure signals of the pressure sensing devices in the pressure sensing area and the pull sensing area are monitored to determine whether the impression operation complies with the sensing rules. Specifically, the sensing rules of each area include:

[0052] for Figure 4 In the pressure sensing area defined by the black line in the maxillary model 110 shown, a pressure threshold value P1 is set for the pressure sensing device set in the area. When the pressure signal values ​​of all the pressure sensing devices in the area are greater than the pressure threshold value P1 at a certain moment, or when the pressure signal values ​​of all the pressure sensing devices in the area reach the pressure threshold value P1 within a preset time interval, it is considered that the requirements of the impression acquisition range are met. At the same time, a time threshold value T1 can be set. When the cumulative time when the pressure signal values ​​of the pressure sensing devices in the area are greater than the pressure threshold value P1 is greater than the time threshold value T1, it is considered that the requirements of the impression operation time of the area are met.

[0053] for Figure 4 The red arrow in the maxillary model 110 indicates the stretch sensing area. For the pressure sensing device set in the area, a pressure difference ΔP2 is set. When any of the stretch sensing areas ( Figure 4When the pressure signal value of all pressure sensing devices (including three separate stretch sensing areas) decreases by more than the pressure difference ΔP2 within a preset time interval, it is considered that a stretching operation has been performed on the stretch sensing area. At the same time, the minimum number of stretching times required can be set, and usually the number of stretching times for each stretch sensing area needs to be greater than 3 times.

[0054] for Figure 4 In the pressure sensing area defined by the yellow area in the maxillary model 110 shown, a pressure threshold value P3 is set for the pressure sensing device set in the area. When the pressure signal values ​​of all the pressure sensing devices in the area reach the pressure threshold value P3 within a preset time interval, it is considered that the requirements for implementing the pressurized impression operation in the area are met. At the same time, a time threshold value T3 can be set. When the cumulative time when the pressure signal values ​​of the pressure sensing devices in the area are greater than the pressure threshold value P3 is greater than the time threshold value T3, it is considered that the requirements for the impression operation time in the area are met.

[0055] for Figure 5 In the mandibular model 120 shown, the pressure sensing area defined by the black line has a pressure threshold value P4 set for the pressure sensing device set in the area. When the pressure signal values ​​of all the pressure sensing devices in the area are greater than the pressure threshold value P4 at a certain moment, or when the pressure signal values ​​of all the pressure sensing devices in the area reach the pressure threshold value P4 within a preset time interval, it is considered that the requirements of the impression acquisition range are met. At the same time, a time threshold value T4 can be set. When the cumulative time when the pressure signal values ​​of the pressure sensing devices in the area are greater than the pressure threshold value P4 is greater than the time threshold value T4, it is considered that the requirements of the impression operation time of the area are met.

[0056] for Figure 5 The red arrow in the mandibular model 120 shows a stretch sensing area. For the pressure sensing device disposed in the area, a pressure difference ΔP5 is set. When any of the stretch sensing areas ( Figure 5 When the pressure signal value of all pressure sensing devices (including three separate stretch sensing areas) decreases by more than the pressure difference ΔP5 within a preset time interval, it is considered that a stretching operation has been performed on the stretch sensing area. At the same time, the minimum number of stretching times required can be set, and the number of stretching times for each stretch sensing area usually needs to be greater than 3 times.

[0057] for Figure 5 The green area in the mandibular model 120 shown in the figure defines a pressure sensing area, and a pressure interval [P60, P61] is set for the pressure sensing device set in the area. When any of the pressure sensing areas ( Figure 5When the pressure signal values ​​of all pressure sensing devices (including two separate pressure sensing areas) reach the pressure interval [P60, P61] within the preset time interval and do not exceed the upper limit of the pressure interval [P60, P61], it is considered that the requirements for implementing the pressurized stamping action of the pressure sensing area are met. If the pressure exceeds the upper limit of the pressure interval [P60, P61], it is considered that the operation exceeds the specification. At the same time, a time threshold T6 can be set. When the cumulative time when the pressure signal values ​​of the pressure sensing devices of the pressure sensing area are in the pressure interval [P60, P61] is greater than the time threshold T6, it is considered that the stamping operation time requirements of the pressure sensing area are met.

[0058] For the operations involved in the above-mentioned sensing rules, operation step rules can be set according to training needs, and operators must follow the instructions to perform the operations in order to be considered in compliance with the operating specifications.

[0059] The operation time of any step in the functional impression, the interval time between steps and the standard value of the total time consumption can be set, so as to prompt the operator to complete the functional impression within a limited time.

[0060] The monitoring terminal 200 is used to receive the pressure signals collected by the pressure sensing devices on the simulation head mold 100, and evaluate the functional impression operation performed by the operator on the simulation head mold 100 according to the above-mentioned sensing rules. The monitoring terminal 200 includes a display device, and displays a virtual image of the simulation head mold 100 on the display device, such as Figure 4 and Figure 5 The upper jaw model 110 and the lower jaw model 120 in the virtual image can also display the representation of the pressure signal of the corresponding pressure sensing device in real time in the upper and lower jaw models of the virtual image, including but not limited to the following methods:

[0061] The pressure sensing device is represented by a corresponding wireframe and / or color block;

[0062] Indicating the pressure value of the corresponding pressure sensing device through color changes and / or numerical display;

[0063] Indicating that an operation satisfies a certain sensing rule, such as any of the above rules, by using a specific color and / or prompt information;

[0064] Specific colors and / or prompt messages are used to indicate that an operation exceeds the specification.

[0065] At the same time, the scores of the operations involved in each sensing rule can be preset, and the monitoring terminal 200 can score the operator's functional impression operation according to the monitored pressure signal, so that the full denture functional impression training system of this embodiment can also be used for functional impression assessment.

[0066] The monitoring terminal 200 can record the process of each functional impression operation, specifically the change process of the pressure signal of the pressure sensing device in the upper and lower jaw models on the virtual image, so as to help the operator understand the deficiencies in the operation and improve or perfect his own operation.

[0067] At present, the number of patients who need full denture restoration is increasing day by day. The full denture functional impression training system and method of this embodiment can improve the clinical practice effect of full-mouth impression of dental students and continuously supply high-quality dental medical talents for my country. At the same time, it can reduce unnecessary clinical discomfort of elderly patients and bring better clinical treatment experience to patients.
