Problems solved by technology

[0005] In order to overcome the current situation that when designing a patient's dentition treatment plan, only the patient's crown data is used as a reference, and the position information of the patient's tooth root cannot be obtained. It may happen that the crown can move and the tooth root interferes, resulting in the failure of the treatment plan. The invention provides a method for reconstructing the patient's tooth root that can obtain the position information of the patient's tooth root and improve the success rate of the orthodontic plan

Embodiment 1

[0036] Such as figure 1 As shown, a method for reconstructing a patient's tooth root comprises the following steps:

[0037] 1), scan the standard tooth model, reconstruct the standard tooth digital model, the standard tooth digital model includes crown data and tooth root data, obtain the tooth root data of the standard tooth digital model; the method of obtaining the standard tooth digital model root data is: delete the standard tooth For the crown data in the digital model, the data above the neckline of each tooth is used as the crown data.

[0038] 2) Reconstruct the patient's dental and jaw digital model, and obtain the crown data from the patient's dental and jaw digital model; the method of obtaining the dental crown data from the patient's dental and jaw digital model is: delete the crown in the dental and jaw digital model For data other than the data, the data above the neckline of each tooth is used as the crown data. The patient's dental model can be obtained by...

Abstract

The invention discloses a method for reconstructing tooth root of a patient. The method comprises steps of scanning a standard tooth model and reconstructing a standard tooth digital model, wherein the standard tooth digital model comprises crown data and root data, and acquiring the root data of the standard tooth digital model; reconstructing a jaw digital model of the patient and acquiring the crown data from the jaw digital model of the patient; and promoting fusion between the root data of the standard tooth digital model and the crown data of the patient, wherein in the tooth model that fusion is completed, each tooth crown is aligned and integrated with matching tooth root on corresponding position so as to present the natural state of the entire teeth. The method disclosed by the invention has the advantages of being able to acquire the tooth root location information of the patient and improve the success rate of a correction scheme.

Description

technical field [0001] The invention relates to the field of oral clinical orthodontics, in particular to a method for reconstructing a patient's tooth root before orthodontics. technical background [0002] Dental deformity is a kind of oral disease with high prevalence rate. The traditional correction method for dento-jaw deformities mostly uses fixed brackets that are bonded to the teeth. The disadvantage is that the steel wire is exposed, which affects the appearance, and the steel wire is easy to damage the oral mucosa. The gap between the steel wire and the teeth is inconvenient to clean, and it is easy to breed bacteria. Plaque causes demineralization and discoloration of teeth. In order to overcome these shortcomings of fixed brackets, invisible appliances without brackets have appeared. Invisible aligners are made of safe elastic transparent polymer materials, which can be removed and worn by patients themselves, and oral hygiene can be maintained normally. And t...
