Abstract: The present invention relates to a tooth-borne guide plate, a mucosa-borne guide plate, a bone-borne guide plate, and preparation and application methods therefor. The method for preparing a tooth-borne guide plate comprises: a) bonding a radiopaque material to teeth, bonding the radiopaque material to the gingival mucosa or/and bonding the radiopaque material to other anatomical features; b) performing CBCT photography, and acquiring CBCT data with radiopaque material information; c) acquiring oral cavity surface STL data with radiopaque material information; d) matching the CBCT data with the STL data; e) determining the positions of an implant and a retention pin; f) generating a base guide plate; g) generating an in-place guide plate; h) generating an implant guide plate; and i) generating a repair guide plate.

Abstract: The present utility model relates to a composite guide plate, comprising a base guide plate (1) and an implant guide plate (7), or comprising a base guide plate (1) and a repair guide plate (10), or comprising a base guide plate (1), an implant guide plate (7) and a repair guide plate (10), wherein the base guide plate (1) is provided with a retention pin sleeve (2); the implant guide plate (7) is provided with an implant sleeve (8) and a retention pin sleeve fastener (5); the retention pin sleeve fastener (5) is fastened on the retention pin sleeve (2) to connect the implant guide plate (7) to the base guide plate (1); the repair guide plate (10) is provided with the retention pin sleeve fastener (5); and the retention pin sleeve fastener (5) is fastened on the retention pin sleeve (2) to connect the repair guide plate (10) to the base guide plate (1).

Abstract: Disclosed are a surgical guide plate and a preparation method therefor. The preparation method comprises the following steps: a) bonding a radiation-blocking material onto an oral mucosa, and putting on an occlusal rim; b) carrying out CBCT photographing to acquire CBCT data carrying information of the radiation-blocking material; c) acquiring STL data of an oral cavity surface; d) matching the CBCT data with the STL data; e) loading occlusal rim data; f) carrying out intelligent tooth arrangement; and g) designing an implant, and generating a surgical guide plate. By means of the preparation method, the level of comfort of a patient can be increased, preparatory processes are reduced, a radiation guide plate does not need to be made, the number of return visits is reduced, the clinical medical cost is reduced, the precision of a surgical guide plate is increased, the software design time is reduced, and the treatment experience is improved.

Abstract: The invention provides a dental restoration system comprising a crown base such as a dentin or an abutment and a shape determiner that surrounds and measures the shape of an apical part in the crown base. The invention also provides a method of dental restoration, which comprises measuring the shape of the crown base that is not surrounded by the shape determiner; determining the shape of the entire crown base; and preparing a crown to be secured on the crown base. The invention exhibits merits such as a much simpler procedure, less gum injury and bone recession, cost-effectiveness, and excellent compatibility with CAD/CAM system, among others.
