Application for application of Article 30, Paragraph 2 of the Patent Law filed. Publication issued on October 31, 2023. Presentations at academic conferences from November 30, 2023 to December 1, 2023. Publication issued on April 30, 2024. Presentations at academic conferences from May 10, 2024 to May 12, 2024.

Presentations at academic conferences from October 19, 2024 to October 20, 2024. This invention relates to a dental skills training device. A dental skills training device is known for training skills in using a needle instrument in dentistry, which has a holding part held by the user and a needle-shaped needle part extending from the tip of the holding part. For example, the dental skills training device described in Patent Document 1 has a pressure-receiving surface against which the tip of the needle part is pressed, and includes a sensor part that measures the force applied from the needle part to the pressure-receiving surface. The needle instrument is a periodontal probe for measuring the depth of a periodontal pocket. Japanese Patent Publication No. 2017-74296 This is an explanatory diagram conceptually representing the position where the needle of a periodontal probe contacts the tooth.This is a diagram showing the configuration of the dental skills training system according to the first embodiment.This is a front view of the dental model according to the first embodiment.This figure shows the configuration of a dental skills training system in a first modified example of the first embodiment.This figure shows the configuration of a dental skills training system in a second modified example of the first embodiment.This figure shows the configuration of a dental skills training system according to a third modified example of the first embodiment.This is a diagram showing the configuration of the dental skills training system according to the second embodiment. The following describes various embodiments of the dental skills training device of the present invention with reference to Figures 2 to 7. <First Embodiment> (overview) The dental skills training device of the first embodiment is a device for training skills in using a needle instrument in dentistry, which has a holding part held by the user and a needle-shaped needle part extending from the tip of the holding part. The dental skills training device comprises a tooth model that simulates at least one tooth, and a contact detection unit. The contact detection unit detects contact between a needle and a predetermined detection area, which is at least a portion of the tooth surface. According to this, contact between the needle portion of the needle instrument and a detection area on the tooth surface is detected. This allows the user to be trained to bring the needle portion of the needle instrument into contact with a specific area on the tooth surface. (composition) As shown in Figure 2, the dental skills training system 1 of the first embodiment comprises a periodontal probe 10 and a dental skills training device 20. The dental skills training system 1 is used to train skills for using the periodontal probe 10 in a dental setting. The periodontal probe 10 is a needle instrument used in dentistry. The periodontal probe 10 is used to measure the depth of periodontal pockets. The periodontal probe 10 is made of a conductive material. In this example, the periodontal probe 10 is made of metal (e.g., stainless steel). The periodontal probe 10 is rod-shaped. The periodontal probe 10 has a holder portion 11 and a needle portion 12. The holder portion 11 is held by the user. The needle portion 12 is needle-shaped, extending from the tip of the holder portion 11 and bending in the middle. The needle portion 12 has a scale at its tip, which is not shown. For example, the scale is composed of scale lines or striped patterns. The dental skills training system 1 may also be equipped with a different needle instrument (for example, a scaler or an explorer) instead of the periodontal probe 10. The dental skills training device 20 comprises a tooth model 21, a DC voltage source 22, a continuity sensor 23, a force sensor 24, a connector 25, a light source 26, and a display device 27. The dental skills training device 20 does not necessarily need to include the light source 26. Furthermore, the dental skills training device 20 does not necessarily need to include the display device 27. In this example, the tooth model 21 comprises teeth 211 that mimic human teeth and gums 212 that mimic human gums. Figure 2 shows a cross-section of the tooth model 21. Figure 3(A) is a front view of the tooth 211 with the gum tissue 212 removed. Figure 3(B) is a front view of the tooth model 21. In this example, the tooth model 21 simulates one set of teeth and gums. However, the tooth model 21 may simulate two or more sets of teeth
