Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will refer to the accompanying drawings to describe specific embodiments of the present invention. It is obvious that the drawings in the following description are only examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.

The first embodiment is as follows:

a dental appliance system provided by the present embodiment includes a series of dental appliances, such as all shell appliances used in an overall appliance plan, that can be designed to progressively implement the overall appliance plan, or that are part of all dental appliances used in the overall appliance plan, designed to implement part of the appliance plan, including a plurality of shell appliances, wherein any shell appliance of the plurality of shell appliances includes a shell body 100, such as the shape of a shell dental appliance as shown in fig. 1, having a number of first cavities 101 and at least one second cavity 102, each cavity being enclosed primarily by lingual, labial/buccal and maxillofacial surfaces, wherein the first cavity 101 is designed to receive a patient's tooth in the appliance plan, the second cavity 102 is designed to receive an aesthetic stage 103 obtained separately from the appliance goals of the respective treatment stages of the dental plan, wherein there are at least two different treatment stages, wherein the aesthetic appearance of the second cavity 102 includes, and the aesthetic appearance of the tooth shape of the tooth 102 is not limited to the tooth's shape.

For each orthodontic patient, the tooth correction of the orthodontic patient needs to design a correction plan according to initial tooth information and target correction information of the patient, the orthodontic patient is divided into a plurality of treatment stages according to the correction plan, and each treatment stage corresponds to a corresponding dental corrector. When the orthodontic patient has teeth missing, the shell-shaped body of the dental appliance corresponding to each treatment stage comprises a second cavity to wrap the corresponding aesthetic teeth 103, and the aesthetic teeth 103 are obtained based on the missing tooth position corresponding to the corresponding treatment stage and tooth shape data of the adjacent and opposite-jaw corresponding teeth at each treatment stage of the dental appliance plan, wherein the tooth shape data of the adjacent and opposite-jaw corresponding teeth comprises but is not limited to the size, shape, position and orientation of the adjacent teeth and the opposite-jaw corresponding teeth.

In this embodiment, as for the tooth form of the beautiful tooth, the tooth form of the corresponding virtual tooth is obtained from the corresponding standard virtual tooth model established in advance according to the missing tooth position and is preliminarily selected as the tooth form of the beautiful tooth. That is, the present embodiment creates a standard virtual tooth model of a full mouth in advance according to the shape of a standard tooth body, in which each tooth position has corresponding standard virtual tooth shape data, preliminarily determines the tooth shape of the beautiful tooth by acquiring the corresponding virtual tooth shape data from the standard virtual tooth model created in advance according to the missing tooth position, for example, when the gap between the No. 1 tooth and the No. 3 tooth is greater than 4mm, determines that the missing tooth position is the No. 2 tooth, and acquires the virtual tooth data corresponding to the No. 2 tooth from the standard virtual tooth model according to the determined missing tooth position to preliminarily determine the tooth shape of the beautiful tooth.

Since the tooth shape of the aesthetic tooth obtained from the standard virtual tooth model is standard tooth shape data, the tooth shape of each tooth is influenced by adjacent teeth and teeth corresponding to a jaw in an actual oral environment, the actual tooth shape data corresponding to the same tooth position is different for different patients, and the tooth shape of the aesthetic tooth is also adapted to the tooth shape data of the adjacent teeth and the teeth corresponding to the jaw for aesthetic purposes, after the corresponding virtual tooth shape data is obtained from the corresponding standard virtual tooth model as the tooth shape of the aesthetic tooth, the tooth shape of the aesthetic tooth is adjusted according to the tooth shape data of the adjacent teeth and the teeth corresponding to the jaw, so that the adjusted tooth shape of the aesthetic tooth is adapted to the tooth shape data of the adjacent teeth and the teeth corresponding to the jaw, wherein the tooth shape includes the size, the shape, the position and the orientation, wherein the tooth size includes the labial width, the mesial width and the gingival height of the tooth, the shape refers to the appearance shape of the tooth, for example, the appearance of incisors is different from that of cusps, the tooth size refers to the occlusal position, the position refers to the major axis of the incisors, such as 13, the major axis of the tooth, the tooth orientation, such as the major axis of the tooth.

In some embodiments, the adjustment of the aesthetic tooth morphology includes, but is not limited to, the following:

adjusting the labial-lingual width of the beautiful teeth according to the labial-lingual width of the adjacent teeth at the missing tooth position, for example, determining and adjusting the labial-lingual width of the beautiful teeth according to the mean value of the labial-lingual widths of the adjacent teeth, for example, adjusting the labial-lingual width of the beautiful teeth to be 90% of the mean value of the labial-lingual widths of the adjacent teeth;

the near-far width of the beautiful teeth is adjusted according to the tooth gaps of the adjacent teeth at the edentulous tooth position; for example, when the tooth gap between adjacent teeth is larger than the near-far-middle width in the tooth form of the beautiful tooth, in order to ensure the beauty, the near-far-middle width in the tooth form of the beautiful tooth can be enlarged according to the corresponding proportion so as to reduce the gap between the beautiful tooth and the adjacent teeth, and solve the problem that the gap between the beautiful tooth and the adjacent teeth is too large due to insufficient lip-lingual width of the virtual tooth in the standard virtual tooth model;

the height of the gingival jaw direction of the beautiful teeth is adjusted according to the height of the gingival jaw direction of the adjacent teeth, and preferably, the height of the gingival jaw direction of the beautiful teeth after adjustment is not higher than the height of the gingival jaw direction of the adjacent teeth;

adjusting the tooth axis orientation of the beautiful teeth according to the tooth axis orientation of the same teeth opposite to the edentulous teeth, specifically, adjusting the tooth axis orientation in the tooth form of the beautiful teeth by referring to the tooth axis mirror image of the same teeth opposite to the edentulous teeth, for example, if the edentulous teeth are No. 12 teeth and the same teeth opposite to the same teeth are No. 22 teeth, adjusting the tooth axis orientation in the tooth form of the beautiful teeth by referring to the tooth axis mirror image of the No. 22 teeth; optionally, when the orientation of the tooth axis of the contralateral same-name tooth deviates from the standard orientation of the tooth axis by more than a preset threshold, the orientation of the tooth axis of the aesthetic tooth refers to the standard tooth axis, wherein the standard tooth axis refers to the tooth axis of the corresponding virtual tooth in the virtual tooth model, that is, when the orientation of the tooth axis of the contralateral same-name tooth deviates from the standard orientation of the tooth axis by more than a preset threshold, the contralateral same-name tooth is said to be an extrados tooth, and the orientation of the tooth axis of the aesthetic tooth is not determined according to the orientation of the tooth axis of the contralateral same-name tooth, and the orientation of the tooth axis of the corresponding standard virtual tooth is adopted as the orientation of the tooth axis of the aesthetic tooth.

However, the aesthetic teeth with the above-mentioned shape may also interfere with occlusion of the jaw teeth, which may cause discomfort to the patient during the correction process and seriously affect the correction effect, so that the generated aesthetic teeth should be prevented from interfering with occlusion of the jaw teeth. In this embodiment, the occlusion relationship may be simulated by a medical animation, and the occlusion simulation may be performed on the aesthetic teeth having the aforementioned aesthetic tooth form and the jaw teeth, and when the simulation result indicates that occlusion interference occurs in the aesthetic teeth, the tooth axis angle of the aesthetic teeth may be adjusted according to the standard tooth axis and the occlusion direction, for example, the occlusion simulation may be performed by changing the orientation of the aesthetic tooth axis within the angle between the standard tooth axis and the occlusion direction, and the tooth axis orientation of the aesthetic teeth may be obtained according to the simulation result. It should be noted that, because the simulation of the occlusion relationship is a commonly used simulation technique at present, the specific method how to adjust the direction of the beautiful tooth axis does not belong to the protection scope of the present invention.

When occlusion interference still occurs after the angle of the tooth axis of the beautiful tooth is adjusted, the height of the beautiful tooth body is gradually reduced by preset increment and occlusion simulation is carried out until occlusion interference is avoided, and the adjusted height of the tooth axis of the beautiful tooth in the gingival jaw direction is obtained.

It should be noted that, in this embodiment, if the missing tooth position corresponding to the aesthetic tooth is tooth number 1 or tooth number 2, it is generally determined whether the current patient has an underbite, and if the current patient is an underbite, the interference between the aesthetic tooth and the underbite on the jaw teeth may not be considered.

It can be seen that, in the dental correction system of the embodiment, because the aesthetic tooth forms of different treatment stages are respectively formed according to the tooth data information of the target tooth states of different treatment stages, the aesthetic tooth forms of different treatment stages are correspondingly changed according to the change of the tooth form data adjacent to and corresponding to the jaw in the correction process, so that the aesthetic tooth obtained according to the aesthetic tooth form cannot be influenced by the adjacent or corresponding tooth to the jaw in the tooth correction process, and the goal of correcting the target in each treatment stage is not influenced, and the aesthetic purpose is achieved.
