Description

Novel children dentition clearance measurement ruler

Technical Field

The utility model relates to the field of medical appliances, in particular to a novel measuring ruler for dentition gaps of children.

Background

The primary caries is one of common oral diseases of children, and is mostly represented by large-area caries, wide caries and advanced caries, if the treatment is not carried out in time, the dental defect can be caused, the oral function is destroyed, and the physical and mental health of the sick children is adversely affected. Because the deciduous teeth are positioned in the back of the oral cavity, the food is often not found and cleaned by parents in time after being plugged, so that the deciduous teeth of the deciduous teeth caries are mostly deciduous teeth. The treatment modes aiming at the mastoplasia mainly comprise drug treatment, filling treatment and repair treatment, and the repair treatment is a treatment mode which is widely applied at present, and a repair treatment scheme of a metal preformed crown is selected clinically when the mastoplasia of caries is repaired.

In the actual treatment process, in order to reduce the time of the pre-formed crown to try on in the mouth, the related size of the suffering tooth such as the near-far pitch diameter and the like is generally measured, and two common test modes at present are that firstly, a dental model is prepared, and the dental model is measured by a vernier caliper, so that the data of the suffering tooth is obtained; secondly, the oral cavity scanner is used for scanning the oral cavity of the infant to obtain parameters. Although the size of the affected teeth can be obtained at low cost, the existing vernier caliper cannot directly penetrate into the oral cavity of a patient to measure, the size of the affected teeth is indirectly obtained by measuring a dental model, the model taking and the gypsum model pouring are time-consuming and labor-consuming, and the difficulty of preparing the dental model is further increased due to the fact that the patient receiving the preformed crown treatment is generally small in age and poor in coordination; the latter, although able to obtain the dimensional parameters of the affected teeth quickly, is the relatively high price of oral scanners and associated equipment on the market today, and also requires special procurement of scanners with smaller probe volumes for pediatric patients.

Accordingly, there is room for improvement in the art.
