Digitally designed personalized sports tooth protector

Abstract

For the defects of manufacturing methods and materials of conventional sports tooth protectors, the invention provides a digitally designed personalized sports tooth protector. The tooth protector is characterized by comprising the following steps: acquiring upper and lower jaw dentition and oral cavity soft and hard tissue data of a patient by using a digital impression technology, and matching the upper and lower jaw dentition in a virtual occlusal frame by using a face arch transfer and virtual fully-adjustable occlusal frame system to perform occlusion registration and lifting occlusion so as to reserve enough space for the sports tooth protector; designing the personalized sports tooth protector through computer aided design software, guaranteeing that the occlusal surface, the lip-cheek side and the palate side are matched with the dentition in shape, the edge is stretched properly, the lip-cheek side and the palate side are wrapped to exceed the range from dentition to gingiva and the protector is attached to the surface form of soft tissue and the lower jaw dentition occlusal surface makes uniform contact with the sports tooth protector worn on the upper jaw; using a novel machinable material polyether ether sulfone (PEES) with high strength and proper elasticity for cutting through computer-aided manufacturing equipment to obtain a finished product of the sports tooth protector, and making the finished product be tried on in the mouth of a sporter. The manufacturing method aims to simplify and optimize the manufacturing method, process and material of the personalized sports tooth protector, shorten the manufacturing period, reduce the size of a finished product, realize more accurate occlusion registration and bring more comfortable wearing experience to a patient.

Description

technical field [0001] The invention relates to a digitally designed personalized sports mouthguard (mouthguard, MG), in particular to a protective device for avoiding or reducing oral and maxillofacial sports trauma, which can assist dentists and dental technicians to apply polyether ether sulfone (PEES) material, the method and application of using digital methods to make personalized sports mouthguards. Background technique [0002] With the increasing socialization of sports, sports-induced damage to the soft and hard tissues of the maxillofacial region, especially tooth damage, has become an increasingly serious social problem. Killer". Mouthguard for sports is an elastic device used to reduce the damage of the oral cavity, especially the teeth and surrounding tissues. It covers the teeth and gums and is mainly worn when participating in sports. It can effectively prevent trauma to the teeth and surrounding soft tissues during sports, and reduce the mouth Risk of faci...

Problems solved by technology

This manufacturing method and the materials used have some disadvantages: first, it can play a good protective role for people with normal occlusion, but when there is anterior bite or deep coverage, after wearing a conventional personalized MG The teeth are still in a non-contact state. When the upper jaw is impacted by horizontal or outward force, the upper anterior teeth are broken because they cannot be supported by the lower anterior teeth and the mandible. When the mandible is stressed, the impact force cannot be effectively buffered, so centric Combination zone and condyle neck fractures

Even for normal occlusal population, the traditional occlusal adjustment may not be accurate enough to prevent the dentition from being fully and evenly contacted, thus spending more clinical time and resulting in an unsatisfactory wearing effect

Moreover, the traditional method needs to take an impression of the dentition and fill it with plaster to make a model. Errors are prone to occur in this process, and the production cycle is also very long.

In addition, in the production of the upper and lower jaw dentition models in the traditional production process, the shape of the lip and buccal side is not clear and complete, which may cause the edge of the personalized customized MG to not fit tightly, resulting in poor retention during wearing; it is inconsistent with the shape of the lip and gums, It is easy to cause oppression, and the palatal side covers the maxillary hard tissue. If the shape is not accurate, it will affect the athlete's pronunciation and saliva secretion, and the wearing comfort is poor.

In terms of material performance, existing materials such as EVA, polyvinyl chloride, acrylic resin, etc., have certain impact resistance, but there are deficiencies such as difficult control of the shape during heating and forming.
