A personalized occlusal surface transparent silicone rubber guide plate and its preparation and method for assisting tooth filling

Abstract

The invention discloses a personalized occlusal surface transparent silicone rubber guide plate and a method for preparing the transparent silicone rubber guide plate and assisting in filling the affected teeth. The filling method of the invention comprises the following steps: 1) when the dental caries is present but the anatomical shape is intact or the dental defect exists, glass ionomer is used to quickly restore the shape; 2)applying a rubber barrier to the tooth and drying the tooth surface; 3) for that adjacent surface, a bean flap adjacent surface forming system and a flowable resin are used to make a personalized adjacent surface forming system, and for the occlusal surface, a transparent silicone rubber guide plate is used to make the personalized occlusal surface transparent silicone rubber guide plate; 4) dental caries removal and dental preparation; 4) filling that diseased tooth with a large block of resin, then, the personalized adjacent face forming system and the personalized occlusal transparent silicone rubber guide are reset to the affected teeth, and the light is cured after pressing and sealing; 5) adjusting that occlusion and polishing of the diseased tooth.The method can restore the original anatomical shape, occlusion relation and adjacent relation of the diseased tooth, save the resin material, reduce the treatment time and improve the treatment quality.

Description

technical field [0001] The invention belongs to the field of endodontics in stomatology, and the specific technology relates to a personalized occlusal surface transparent silicone rubber guide plate and a method for preparing and assisting tooth filling. Background technique [0002] At present, resin filling treatment is mainly used for the treatment of caries and other tooth defects. In resin filling, it is still a technical difficulty to restore the anatomical shape of the occlusal surface of the tooth and make it perform normal functions, which requires doctors to have certain clinical experience. The reasons are as follows: 1. Tooth anatomy is complex; 2. The anatomy of teeth in different tooth positions is quite different; 3. The anatomy of teeth in the same tooth position is different among individuals; 4. After tooth preparation, only the Doctors restore the shape of the tooth with experience, which may change the original pit and groove position of the occlusal su...

Problems solved by technology

This technology has the following disadvantages: 1. When restoring the anatomical shape of the occlusal surface, if you choose one-time molding (that is, one-time molding of the cusp shape), the resin polymerization shrinkage will cause micro-leakage at the edge of the filling body; 2. When restoring the anatomical shape of the occlusal surface , if you choose step-by-step forming (i.e. forming each cusp separately), the operation will be cumbersome and time-consuming; 3. The indications are narrow, and it is only suitable for carious lesions with no damage to the anatomical shape of the occlusal surface; 4. The female mold material such as If resin is selected, it will bond with the filling resin, resulting in the inability to remove the female mold, and the resin material is opaque, making it impossible to observe the sealing of the edge of the filling body

[0004] For resin materials, the limitation of polymerization shrinkage and curing depth is still its defect, which requires layering when filling, which consumes a lot of time, which not only reduces the efficiency of treatment, but also affects the temporomandibular joint if the patient continues to receive treatment for a long time. Some damage, and affect the healing experience
