Technical Field

[0001] This utility model relates to the field of measuring ruler technology, specifically a grooved measuring ruler for oral cavity use. Background Technology

[0002] The Department of Stomatology is a clinical department within the medical disciplines that specializes in the study of oral and maxillofacial diseases and the treatment of dental caries and dentition. Originally affiliated with the Department of Otolaryngology, it later became an independent specialty. Its scope of treatment includes orthodontics, periodontal disease treatment, and maxillofacial tumor surgery, with a focus on typical diseases such as tetracycline staining, leukoplakia of the tongue, and submandibular space infection. It comprises departments of oral surgery, oral medicine, prosthodontics, and orthodontics, and offers specialized treatments such as root canal therapy, guided tissue regeneration techniques, and dental implants.

[0003] In daily dental work, it is often necessary to use measuring rulers to measure patients' teeth, gums, tongue, etc., to obtain accurate measurement data. However, most existing vernier calipers use screws to fix the vernier, which requires the vernier to be inserted into the patient's mouth during measurement. It is very inconvenient for doctors to put their hands into the patient's mouth to tighten the screws, and the patient's mouth does not have enough space to accommodate both the caliper and the doctor's fingers at the same time. This makes it impossible to fix the vernier during measurement. When the vernier caliper is removed from the patient's mouth, if the vernier is bumped, it will move, resulting in measurement errors. Therefore, it is necessary to propose a multi-purpose grooved measuring ruler for dentistry to solve the above problems. Utility Model Content
