The present application claims priority to Chinese Patent Application No. 201811178300.3, entitled “Tooth Virtual Editing Method and System”, filed in the Chinese Patent Office on Oct. 10, 2018, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present application relates to a tooth virtual editing method and system, a computer device and a storage medium.

BACKGROUND

At present, there is a problem existing in the field of oral health globally, i.e. the incidence rate is high while the consultation rate is low.

One reason is that many parts of the oral cavity (such as the posterior molars and the lingual and palatal sides of the dentition) are inconvenient for people to see, and people usually cannot see pathological precursors in the oral cavity, and would not actively make an appointment with the doctor until they experience symptoms such as pain. However, when pain occurs in the oral cavity, people may have got oral diseases such as dental caries, pulpitis, periapical periodontitis, dentin hypersensitivity, gingival recession, etc., leading to the problem of delayed treatment.

For those who attach importance to oral health, they usually take a regular oral health examination every half year or year in medical institutions. However, in some cases, the pathogenic process of oral diseases is fast. When a patient goes to a medical institution for a regular oral health examination, oral diseases may have occurred, so that the problem of delayed treatment also exists.

In addition, before an oral treatment plan is carried out, it is currently difficult in the industry to demonstrate a comparison of changes in the appearance of the dentition before and after treatment.

When the patient goes to a medical institution for oral examination, a dentist can see the patient's dentition. At present, some medical institutions are able to show a three-dimensional true color model of the appearance of full dentition of the patient. However, it is currently difficult to show the patient the three-dimensional true color model of the appearance of full dentition of the patient after the patient has received oral treatment from the dentist. The specific numerical change in the appearance of the dentition before and after the treatment plan is completed is also currently difficult to quantitatively show the patient. The inventor have appreciated that two problems may be caused:

Problem I: The patient do not have an intuitive feeling about the effect of oral treatment, so that some oral treatments are less attractive to the patient. Therefore, some oral problems in the population, such as crowded dentition, dentition defects, gingival recession, dental plaque, pigmentation, etc., are not treated timely.

Problem II: It is difficult for the patient and dentist to create a quantitative convention for an oral treatment plan, which proposes a risk of medical disputes. For example: during orthodontic treatment, it sometimes needs to do stripping. Stripping, also known as “Interproximal Enamel Reduction”, is the removal of a small amount of enamel from between the teeth to reduce their width so as to gain space necessary for orthodontics. Here, there are many requirements on the “removal of a small amount”. The time, position and size of stripping all require professional design and precise operation. Generally, the size of stripping for a single tooth needs to be strictly controlled (within 0.2-0.5 mm), otherwise many negative problems may be caused, including tooth sensitivity caused by interproximal enamel reduction, vulnerability to dental caries after stripping, etc. However, the patient does not have an intuitive feeling about the position and size of stripping, and the dentist often does not inform the patient of the particular position and size of stripping in advance. Therefore, stripping is easy to become a blind spot in dentist-patient communication. A few medical institutions may make use of this blind spot in dentist-patient communication, and perform irreversible large-size stripping operation on the patient in the retainer stage in the late orthodontic treatment without authorization, which causes vulnerability of the patient to tooth sensitivity or even function impairment, thereby further inducing the patient to receive veneering or cosmetic crown treatment. Therefore, by inducing patients to receive excessive medical treatment, the purpose of making huge medical bills is achieved.

SUMMARY
