Description

Technical Field

[0001] The invention relates to a novel multi-angle adjustable dental model articulator. Background Art

[0002] A dental mold is a model used by doctors to analyze tooth plastic surgery plans. It is usually made by mixing tooth powder and water. It tastes like toothpaste and has a minty flavor when you bite it. When making a dental mold for occlusion, it is divided into upper and lower bites, packed in a plastic box, and put on the teeth with your mouth open. When the occlusion model is almost dry, take it off as a whole and use other materials to make a dental mold.

[0003] Dental mold making: Taking a dental mold means using professional materials to copy the model of your teeth in your mouth, and then pouring it with plaster, so that porcelain teeth can be made with the plaster model. After the initial formation of the dental mold, it needs to be trimmed and finalized.

[0004] The new multi-angle adjustable dental model articulator imitates the upper and lower jaws and the temporomandibular joint of the human body, and is used to fix the upper and lower jaw models and the occlusal tray to analyze and diagnose dental problems, and to prepare oral restorations according to the patient's specific occlusion conditions. General articulators make the maxillary and mandibular surfaces contact by adding plaster, so that the upper and lower dental models can reach a state of simulating human tooth occlusion. General articulators need to add a large amount of plaster and spend a lot of time to make the upper and lower dental models reach the occlusal state, resulting in a large amount of plaster waste, increased costs, and extended working hours. This is far from meeting the current requirements of people for this product. Therefore, how to design a new multi-angle adjustable dental model articulator has become our current problem to be solved. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a new multi-angle adjustable dental model articulator which is easy to use, simple to operate, and convenient for making tooth models. During the making process, the tightness, height and other multi-angle adjustments can be performed. After the making is completed, the fit is high and the trimming is convenient. At the same time, it can be suitable for the making of various tooth models and has practicality and wide application.
