Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis technology, specifically a spring-loaded, fine-tuning temporary dental prosthesis connection structure. Background Technology

[0002] Dental models are three-dimensional entities created by pouring model material from oral impressions. They are used to reproduce the morphology and structure of prepared teeth, adjacent teeth, opposing teeth, and soft and hard tissues in a patient's mouth. They help dentists visually analyze tooth loss, occlusal relationships, and alveolar bone morphology, develop personalized restoration plans, ensure a precise match between the restoration and the oral structure, and are used in dental education to demonstrate tooth anatomy. In research, they simulate specific oral conditions and verify the effectiveness of restorative techniques.

[0003] Currently, temporary dental prostheses mostly use adhesives or simple clasps for connection. Adhesive fixation relies on manual application, making it difficult to precisely control the amount used, and it lacks an effective positioning structure. Simple clasp connections mainly rely on the elastic deformation of metal clasps for fixation, but the shape and size of the clasps are difficult to adjust, and cannot meet the oral environment and prosthesis restoration needs of different patients. Utility Model Content

[0004] The purpose of this invention is to provide a spring-loaded, finely adjustable temporary prosthesis connection structure to address the issues raised in the background art, where current temporary prostheses often rely on adhesives or simple clasps for connection. Adhesive fixation depends on manual application, making precise control of dosage difficult and lacking an effective positioning structure. Simple clasp connections primarily rely on the elastic deformation of metal clasps for fixation, making clasp shape and size adjustment difficult and unable to meet the needs of different patients' oral environments and prosthesis restoration requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spring-loaded, fine-tuning temporary prosthetic connection structure, comprising a first spring and two fixing components. The first spring is positioned between the two fixing components. A flexible metal connecting block is installed at both ends of the first spring, and the first spring is fixedly connected to the fixing components via the flexible metal connecting blocks. A second spring is installed on the inner side of the first spring, and both ends of the second spring are fixedly connected to both ends of the first spring. A connecting rod is installed between the second spring and the first spring, and the connecting rod is rotatably connected to the second spring. A connecting sleeve is fixedly installed on the end face of the first spring facing the second spring. Threads are provided on the outer wall of the connecting rod and the inner wall of the connecting sleeve, and the connecting rod is threadedly connected to the connecting sleeve.

[0006] Preferably, both the first spring sheet and the second spring sheet are arranged in an arc shape.

[0007] Preferably, there are two connecting rods and two connecting sleeves, and the connecting rods and connecting sleeves are symmetrically arranged about the center line of the first spring plate.

The medical silicone ring 10 contacts the gum, preventing prolonged pressure, congestion, and inflammation of the gum.

[0024] Working principle: Based on the denture restoration position, the flexible metal connecting block 3 is bent to roughly match the direction of the denture between the first spring plate 1 and the fixing member 2. The two fixing members 2 are then placed on the dentures on both sides of the denture to be restored. The fastening bolt 6 is rotated so that one end contacts the denture inserted into the installation cavity 5, thus tightening and limiting the inserted denture and installing and fixing the restoration connection structure. The connecting rod 8 is rotated according to the denture restoration needs. The connecting rod 8 is threadedly connected to the connecting sleeve 9. As the connecting rod 8 rotates, the tension or thrust applied to the first spring plate 1 changes, thereby adjusting the curvature of the first spring plate 1, accurately fitting the abutment tooth and controlling the tightness.
