Embodiment
[0031] Such as Figures 1 to 4 shown. The invention discloses a direct manufacturing method of a novel self-locking denture, which can be realized through the following steps:
[0032] Step 1: Obtain the oral data of the patient, obtain the morphological data of the alveolar bone and the relationship data between the dentition;
[0033] Step 2: According to the acquired alveolar bone and dentition data, use 3D modeling software to carry out 3D modeling of alveolar bone and teeth, and design a personalized implant 1. Specifically, reverse reverse engineering is used to obtain the data of the patient's oral cavity with missing teeth, and then use 3D modeling software to process the acquired point cloud data to obtain a 3D model of the alveolar bone and teeth; the shape of the alveolar bone and the oral cavity Analyze the internal environment and design a personalized implant that meets the specific conditions of the patient's oral cavity1.
[0034] Step 3: On the basis of the...

The invention discloses a direct manufacturing method of a novel self-locking type false tooth body, which comprises the following steps: acquiring data of the oral cavity of a patient, morphological data of alveolar bones and relational data among dentitions; carrying out three-dimensional modeling of the alveolar bones and teeth by adopting three-dimensional modeling software according to the acquired data of the alveolar bones and dentitions, and designing an individualized implant; on the basis of the individualized implant, carrying out secondary design on the implant, and designing a threaded rod corresponding to the individualized implant; importing the acquired three-dimensional model data into a 3D printer, and directly molding a tooth implant with an expansion self-locking function by adopting a layered accumulative manufacturing method; and carrying out post-treatment processes, such as surface polishing, cleaning, disinfection and heat treatment, on the tooth implant according to specific clinical requirements. The direct manufacturing method disclosed by the invention has high efficiency and low cost; and on the premise of ensuring individualized customization of the implant, the implant with the expansion self-locking function is molded, and the using effect is good.
Description
technical field [0001] The invention relates to the technical field of artificial dental implant manufacturing, in particular to a novel self-locking artificial tooth direct manufacturing method. Background technique [0002] Artificial tooth implant is a common treatment for tooth loss at present. It mainly implants a biocompatible metal artificial tooth root into the alveolar bone at the tooth loss, and through the close integration of artificial tooth root and alveolar bone, The artificial tooth root is used as the base for the implant dental model. Since the adjacent teeth are not ground away like fixed dentures, there is no damage to adjacent teeth, and there is no factor for secondary tooth decay, so it is a more stable method than fixed dentures. When a person uses a removable denture due to missing multiple teeth, the periodontal tissue (gum) will be exerted force, so the gum will feel uncomfortable, and the foreign body sensation in the mouth will be severe due to ...
