Embodiment Construction

[0019] The structure of the oral plaque biofilm model in situ of the present invention is attached figure 1 - attached Figure 4 As shown, 1 in the figure is a hard retainer, and the tooth and gum molds are arranged on the hard retainer 1, and the tooth molds on the outer surface of the hard retainer (1) are pressed with circular tooth pieces or restorations. body material 2. The hard retainer 1 is composed of the maxillary retainer 3 and the mandibular retainer 4. The incisal ends of the maxillary retainer 3 and the mandibular retainer 4 are closed into one body. The gingival ends of the maxillary retainer 3 and the mandibular retainer 4 are Open-mouthed, ending distal to the last molar. The maxillary retainer 3 is pressed with the surface mold of the maxillary teeth, and the mandibular retainer 4 is pressed with the surface mold of the mandibular teeth. 5 among the figure is the working model of the upper jaw, and 6 is the working model of the lower jaw.

Abstract

The invention discloses an in-situ plaque biological membrane intraoral model and a preparation method thereof. The in-situ plaque biological membrane intraoral model is provided with rigid retainers, each rigid retainer is provided with a tooth and gingiva model, circular dental films or restoration materials to be researched are pressed on the tooth models on the outer surfaces of the rigid retainers in a fitted mode, and each rigid retainer is composed of an upper jaw retainer and a lower jaw retainer. The preparation method comprises the following steps that an upper jaw working model and a lower jaw working model are made; the working models are finished; the dental films and the restoration circular blanks are fixed; alginate materials are used for covering; the rigid retainers with the circular blanks are pressed through a laminator; the circular dental films and the surfaces of the restorations are polished and windowed; finishing is conducted on original shapes of the rigid retainers, and the in-situ plaque biological membrane intraoral model is obtained. According to the in-situ plaque biological membrane intraoral model and the preparation method thereof, the defects existing in the prior art are overcome, dental injuries of volunteers who participate in research are thoroughly avoided, and a person subjected to research does not have a tooth ache.

Description

technical field [0001] The invention relates to an in-situ bacterial plaque biofilm intraoral model used in the oral cavity, and is an intraoral model for studying oral microecology and a preparation method thereof. Background technique [0002] Dental plaque is a typical bacterial biofilm, which is a soft and unmineralized bacterial population wrapped in matrix and adhered to the surface of the tooth or restoration, which cannot be washed away by water or rinsed away. The unique structure, sticking together and growing together, the microecological imbalance in dental plaque is not only highly related to common oral diseases such as caries, periodontitis, oral mucosal disease, etc., but also proven to be related to some systemic diseases. Therefore, dental plaque on oral surfaces or restorations has been studied for quite a long time. The traditional method of studying dental plaque in the mouth mostly uses the method of scraping, but this method often destroys its structu...
