Description
Technical Field
The invention relates to the technical field of dental measuring instruments, in particular to a dental arch measuring device.
Background
According to the fourth national epidemiological investigation result of oral health in 2015, the caries rate of children in China is rapidly increasing, wherein the caries rate of the deciduous teeth of the age group of 5 years is increased to 71.9%, the caries average (dmft) is increased to 4.24, and the caries missing (mt) is 0.01,0.2%. Premature primary teeth loss can lead to inclination of adjacent teeth to gaps and extension of the teeth of the jaw, and can influence normal eruption of inherited permanent teeth to cause malocclusion, and the loss of a plurality of primary teeth can influence the chewing function of an infant, so that the development of dental arches and jawbones of the infant is influenced. So that the gap maintainer should be designed after the teeth of the child are lost early. The ages of 4-7 years and 11-13 years are the second and third rapid development stages of the maxillofacial region. The length of the maxilla from infant to adult increases by about 2.5 times (maximum in molar area), the width 1.6 times, and the palate top height increases by about 10mm. The length of the mandible increases up to the molar area, e.g. the distance from the second deciduous molar to the angle of the mandible, with the neonate about 10mm, about 20mm by age 6 and the adult about 40-45 mm. The anterior mandibular width increases less after the deciduous teeth erupt. When the permanent incisors erupt (6-10 years old), the length and diameter of the arches of the upper and lower jaws are increased, the upper jaw is about 1.4mm, and the lower jaw is about 0.1mm; the width between the deciduous cuspids increases, and the average of the upper and lower jaws increases by 3.2mm. Therefore, the children in the development stage need to be checked regularly, and in principle, the children need to be checked for 3-6 months regularly, and the development conditions of the jaw bones and dental arches of the children need to be observed. Currently, in medical institutions, it is common to:
1. model measurement analysis, taking intraoral impression of the child patient at each visit, and measuring through the model after the model is poured. The intraoral mold taking process is relatively uncomfortable, and the infant is not easy to match. The whole process is complex, the comfort is poor, and the time consumption is long.
2. CBCT three-bit reconstruction analysis: children are in the growth and development stage and are more sensitive to radiation, and the radiation is easy to have adverse effects on thyroid, parotid gland, pituitary gland, eyes and the like, and although the single irradiation radiation dose of CBCT is small, the accumulation of the radiation dose of X-rays and the increase of the frequency of personal examination can cause potential harm to human bodies. The expense is more expensive, and parents of the sick children worry about the method, so that the acceptance is poorer.
3. Computer-aided model analysis: the equipment requirement is higher, and each time, professional personnel are required to carry out intraoral scanning, so that the process is complicated, time-consuming and expensive. Therefore, the existing method for measuring the dental arch of the child is relatively inconvenient.
