Description

Denture forming method

The invention provides a denture shaping setting method, in particular to a denture forming setting method which can accurately fit the patient in size and position to facilitate installation and use.

According to the teeth, the teeth occupy a very important position in the intake of general solid foods, but the teeth may be worn out, shed, eroded and the like due to factors such as long-term use, aging, disease, poor constitution, or poor cleaning. In addition to affecting the appearance and the sound of speech, the influence of general solid food intake may cause various problems such as malnutrition, hidden hunger, weakness, or indigestion. Therefore, denture components have been studied in the dental industry.

The conventional dental prosthetic components usually use the computerized tomography technique to scan the upper and lower teeth of the patient, and then make a gypsum film according to the scanning result to assist in judging how to make the dental prosthetic components and judge the production. It is appropriate to wear and use the denture components.

However, since the occlusal system of the upper row of teeth and the lower row of teeth involves the cooperation of cartilage and muscles, it is inevitable that the gypsum film is inevitably inaccurate with the actual occlusion, resulting in a need for more testing and correction time. With labor, it also causes problems for patients.

Therefore, how to solve the above problems and deficiencies in the above-mentioned applications, that is, the inventors of the present invention and those involved in the industry are eager to study the direction of improvement.

Therefore, the inventors of the present invention have collected the relevant materials in view of the above-mentioned deficiencies, and through multi-party evaluation and consideration, and through years of experience accumulated in the industry, through continuous trial and modification, the size and setting position are designed. An inventor who can accurately cooperate with the patient to facilitate the installation of the denture forming method.

The main purpose of the present invention is to improve the accuracy of the installation and occlusion of the prosthesis in cooperation with the patient.

In order to achieve the above object, the present invention first performs the step (a) using at least one stereo scanner to capture the shape of the upper jaw of the patient and the shape of the lower jaw to generate a stereoscopic upper jaw data, a stereo mandibular gum data, and an upper The mandibular occlusion record, which directly obtains the actual accurate information, and performs step (b) scanning at least one computed tomography scanner with the shape of the maxillary bone and the shape of the mandible to generate a faulty maxillary data and a fault Mandibular data.

Then performing step (c) using at least one three-dimensional processing device to integrate the aforementioned stereoscopic upper jaw data, stereo mandibular gum data, upper and lower jaw occlusion records, fault maxillary data, and tomographic data of the mandible to generate a three-dimensional full-toothed data. The three-dimensional full-tooth data can be matched with the actual upper jaw, mandibular, maxillary, mandible, and occlusion conditions of the patient.

Step (d) through the three-dimensional full-tooth data planning at least one of the prosthesis on the side of the maxillary bone of the patient, the plurality of fixations on the upper prosthesis, and at least one on the side of the mandible of the patient The prosthesis below, and the detailed position and size of the fixed part under the fixed prosthesis, and finally the step (e) according to the plan to make the upper prosthesis and the lower prosthesis, and use the fixed top of the plan The upper body is implanted into the upper jaw of the patient, and the lower prosthesis is implanted into the mandible of the patient by using the various fixing members selected for planning.

Therefore, the produced upper prosthesis, lower prosthesis, and its setting position and occlusal position will be consistent with the actual condition of the patient. With the above technology, the error of the conventional denture component can be large, and the problem of the patient is troubled. Breakthrough, size and position can be accurately matched with the patient to facilitate the practical progress of installation and use.
