In the process of implementing the dental implant, components such as an implant, an implant base and an implant crown need to be used, the implant is driven into the alveolar bone of a patient, the implant base is fixedly arranged on the implant, and the implant crown is fixedly sleeved on the implant base. The whole implant consisting of the implant, the implant abutment and the implant crown can repair the missing tooth in the oral cavity of a patient, so that the missing tooth is replaced to realize the functions of beautifying the oral cavity and chewing food.
The internal conditions of the oral cavity of each patient are different, so that a good repairing effect can be achieved only by installing the implant matched with the oral cavity, otherwise, the dental implant cannot be effectively repaired, and other healthy teeth can be damaged more seriously. Therefore, before the dental implant operation, it is necessary to prepare an implant, an implant abutment, and an implant crown in advance according to the internal condition of the oral cavity of a patient. In the prior art, the most accurate method for manufacturing the implant abutment is personalized customization, that is, a personalized abutment model is designed in a digital mode according to the actual oral cavity condition of a patient, and then a corresponding personalized abutment is obtained through 3D printing or instantiation in other modes. Such a personalized abutment, by fully conforming to the patient's gums, is the most accurate, however, the cost, equipment and operational requirements are also the highest. Therefore, more generally, the finished abutment is ground to obtain an abutment suitable for a specific oral condition based on the actual oral condition of a patient.
The finished product base station refers to a base station which is produced in advance by a manufacturer and has a certain specification, and after the base station is ground or cut based on a finished product ground state, redundant materials on the finished product base station are removed, so that the finished product base station suitable for a specific patient can be obtained. The process of manufacturing the planting base station in the prior art is approximately: and selecting the most approximate finished product base station according to the internal condition of the oral cavity of the patient, manually cutting the finished product base station, and then fixedly installing the cut finished product base station on the implant. However, the precision of manual cutting is very low, which is difficult to ensure the suitability for the oral cavity of a specific patient, and the realization of accurate matching is difficult, thereby greatly limiting the repairing effect of the implanted tooth.
As shown in fig. 1, in order to solve the above problem, the present invention provides a method for controlling cutting of a digital abutment, the method comprising the steps of: .
S1, importing three-dimensional data of finished product base stations of multiple models. There are multiple models of finished product bases, each model of finished product base has the corresponding three-dimensional data of the finished product base, and in step S1, all the possible three-dimensional data of the finished product base needs to be imported into the system in advance.
S2, obtaining three-dimensional data of missing gingiva of a patient, and matching the three-dimensional data of the missing gingiva to obtain three-dimensional data of the finished abutment with a corresponding model. Based on the missing gum three-dimensional data, the gum contour, the gum penetrating height and the cuff form can be obtained, and then the three-dimensional data of the finished abutment with the corresponding model can be matched according to the gum contour, the gum penetrating height and the cuff form. In step S2, the key point is to match the obtained three-dimensional data of the finished abutment, and select the most suitable finished abutment, and the volume of the corresponding finished abutment should be larger than that of the required abutment, so as to ensure that the abutment matching with the gum contour, the transgingival height and the cuff shape of the patient can be obtained after the redundant part is removed by cutting.
And S3, determining three-dimensional data of a cutting area on the matched three-dimensional data of the finished abutment according to the three-dimensional data of the missing gingiva. In step S3, the process of determining the three-dimensional data of the cutting region on the three-dimensional data of the finished abutment is similar to the design process, the operator defines the three-dimensional data of the cutting region on the three-dimensional data of the finished abutment according to the three-dimensional data of the missing tooth and gum, and the system determines the three-dimensional data of the cutting region according to the instruction output by the operator, thereby completing step S3.
And S4, cutting a finished product base station according to the three-dimensional data of the cutting area to obtain a target base station, wherein the finished product base station corresponds to the three-dimensional data of the finished product base station. In step S4, an operation command is outputted based on the three-dimensional data of the cutting region, and the operation of the cutting abutment is controlled to cut a target abutment corresponding to the actual condition of the oral cavity of the patient on the finished abutment.
Through automatic matching finished product base station to confirm the cutting region three-dimensional data according to disappearance gum three-dimensional data and finished product base station three-dimensional data, cut finished product base station based on cutting region three-dimensional data again, can make different base stations according to different patients' oral cavity internal conditions from this, in order to realize accurate matching, promote the restoration effect of planting the tooth. Based on the technical scheme, on one hand, the threshold in the aspects of cost, equipment and operation is reduced, the wide popularization and use are facilitated, on the other hand, the cutting process is fully automatic, errors possibly caused by manual cutting are avoided, and the precision of the base station is improved.

and cutting a finished product base station according to the three-dimensional data of the cutting area to obtain a target base station, wherein the finished product base station corresponds to the three-dimensional data of the finished product base station.
When the manufacturer of the finished product base station can provide corresponding data, the data synchronization with the manufacturer database is carried out to obtain the three-dimensional data of the finished product base stations of a plurality of models; and when the manufacturer of the finished product base station can not provide corresponding data, the three-dimensional data of the finished product base stations of a plurality of models is obtained by performing three-dimensional scanning on the finished product base stations. In the process of implementing the technical scheme, different data acquisition modes can be adopted based on actual conditions, and a data basis is provided for subsequent matching and determination of the three-dimensional data of the cutting area.

The method is characterized in that the base matched with the oral condition of a specific patient is obtained by cutting a finished base, the process is similar to the sculpturing process, redundant materials are required to be removed, useful materials are reserved, and in the process, the key point is to determine which redundant materials are and which useful materials are. The technical scheme provides a better implementation mode, after a gum cuff model and a finished product abutment model are generated respectively through missing gum three-dimensional data and finished product abutment three-dimensional data, the relative position relation of the gum cuff model and the finished product abutment model is simulated and generated in system software, namely, the difference between the gum cuff model and the finished product abutment model is compared, a cutting area is determined according to the relative position relation of the gum cuff model and the finished product abutment model, and then the cutting area three-dimensional data is generated. In this way, the cutting area can be determined in an intuitive manner simply by determining which of the excess material and which of the useful material are. As shown in fig. 3, the whole of fig. 3 is the finished abutment 3, the solid line part is the target abutment, i.e. the useful material, and the dotted line part is the excess material, and the range of the dotted line part can be determined according to the relative position relationship between the gingival cuff model and the finished abutment model.

Preferably, the three-dimensional data of the missing gingiva of the patient is acquired by intraoral scanning or oral cavity model scanning.

However, the cost of the intraoral scanner is too high, and when the intraoral scanner is not equipped during dental implantation, the three-dimensional data of missing teeth and gums of a patient can be obtained by making an oral cavity model and then performing three-dimensional scanning on the oral cavity model.
