Description

Technical Field

[0001] This utility model relates to the field of oral medical device technology, specifically to a horizontal clamping screw-type loose tooth fixation device. Background Technology

[0002] Periodontal disease is a very common oral disease, mainly manifested as periodontal recession, exposed tooth roots, loose teeth, and even spontaneous tooth loss. Currently, the main treatments for periodontal disease include: medication, supragingival and subgingival scaling, periodontal surgery, and tooth stabilization.

[0003] Preserving teeth is the ultimate goal of periodontal treatment, and stabilizing loose teeth is the most important means of preserving teeth. The main existing methods for stabilizing loose teeth include: 1. Splint-type removable dentures: Performed after extracting loose teeth to repair dentition defects. The main placement method is vertical placement to avoid lateral forces on the remaining teeth during insertion and removal. Its main function is to prevent excessive occlusal trauma to the remaining teeth during chewing; 2. Fixed dentures (porcelain crowns and bridges): Also performed after extracting excessively loose teeth. The remaining teeth need to be prepared and ground to have a certain axial inclination and a common path of insertion so that the porcelain crowns and bridges can be placed vertically.

[0004] All of the above methods for fixing loose teeth use vertically oriented fixation structures, require grinding down remaining teeth, and should be performed only after basic periodontal treatment has been completed and the results are confirmed. Utility Model Content

[0005] This invention provides a horizontal clamping screw-type loose tooth fixation device that can be used in the early stages of loose teeth to promptly repair tooth defects without affecting subsequent periodontal treatment.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A horizontally clamping screw-retaining loose tooth fixation device includes a labial / buccal side splint, a lingual / palatal side splint, and a retention screw. Both the labial / buccal side splint and the lingual / palatal side splint include a tooth-contacting part and a retention part. The labial / buccal side splint and the lingual / palatal side splint are clamped on the inner and outer sides of the tooth, respectively. The opposing surfaces of the tooth-contacting parts are matched with the morphology of the labial / buccal and lingual / palatal surfaces of the tooth, respectively. The retention part is embedded in the interdental space or the end of the dental arch and is fixedly connected by the retention screw.

[0008] Furthermore, the retaining part is located at both ends of the labial / buccal side splint and the lingual / palatal side splint, with one end connected by a hinge and the other end connected by a retaining screw.

[0009] Furthermore, the retaining portion is located at both ends of the labial / buccal side splint and the lingual / palatal side splint, and both ends are connected by retaining screws.

[0010] Furthermore, the retaining part is located in the middle of the labial / buccal side splint and the lingual / palatal side splint, and is connected by retaining screws.

[0011] Furthermore, the retention portion of the buccal splint overlaps with the retention portion of the lingual-palatal splint, and the retention screw horizontally connects the two retention portions.

[0012] Furthermore, the retention portion of the buccal splint overlaps vertically with the retention portion of the lingual-palatal splint, and the retention screw vertically connects the two retention portions.

[0013] Furthermore, the upper ends of the labial / buccal splint and the lingual / palatal splint extend to the crown of the tooth.

[0014] Furthermore, the retaining part is provided with a threaded hole, and the retaining screw is threadedly connected to the buccal and lingual clamps.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention can be used in the early stages of tooth loosening to promptly repair missing teeth without affecting subsequent periodontal treatment. When in use, the labial and buccal splints and the lingual and palatal splints are respectively held on the inner and outer sides of the teeth. The opposing surfaces of the tooth clasping parts are matched with the labial and buccal surfaces and the lingual and palatal surfaces of the teeth, respectively. The retention part is embedded in the interdental space (including edentulous space and interdental space) or the end of the dental arch and is fixedly connected by retention screws. It is easy to put on and take off and is not likely to damage the remaining teeth. Attached Figure Description
