Clamping ring in-position adjusting and changing device and method

Abstract

The invention relates to the field of dental denture production, and discloses a clamping ring in-position adjusting and changing device and method. The clamping ring in-position adjusting and changing device comprises a clamping ring contracting part used for contracting a clamping ring arm and a clamping ring expanding part used for expanding the clamping ring arm. The clamping ring in-position adjusting and changing device achieves contraction adjusting and changing of a clamping ring through guide cambered surfaces on the two sides of the clamping ring contracting part for the over-loose clamping ring. The clamping ring in-position adjusting and changing device achieves expansion adjusting and changing of the clamping ring through force arms on the two sides of the clamping ring expanding part for an over-tight clamping ring. Compared with a traditional orthodontic clamp adjusting and changing mode, the device has the advantages that the controllability is higher, the operation difficulty is lower, the clamping ring can be adjusted and changed more stably, and the risk that the clamping ring is broken in the adjusting and changing process is reduced.

Description

technical field [0001] The invention relates to the field of dental denture production, in particular to a clasp in-place adjusting device and an adjusting method. Background technique [0002] Removable partial dentures are the main repair method for removable dentures in oral dentition defects. Dentition defects are clinically frequently-occurring and common diseases in oral restoration. Sexual activity will be affected. Furthermore, the remaining teeth will cause caries or periodontal disease of the remaining teeth due to food impaction in the space between the missing teeth. In order to maintain the integrity of the oral and maxillofacial system, maintain the health of the oral tissue, and restore the patient's masticatory function as much as possible, it is necessary to repair the missing teeth in time. The treatment methods for dentition defects include: removable partial dentures, fixed dentures, and removable and fixed combined restorations. [0003] Removable par...

Problems solved by technology

Among all types of clasps, the three-arm clasp is the most commonly used type for doctors to design. After the design is completed, the three-arm clasp needs to be manually adjusted and polished by the technician to fit the model better. To achieve a fully seated effect, this is mainly because the design of the removable partial denture restoration needs to be completed through the design software. The data of the model in the design software is generated by the model scanner. After the design is completed, the restoration is finally obtained by printing. The design of the restoration also varies with the level of the technician. All the above links have caused errors between the model and the final restoration, resulting in the incomplete fit between the obtained restoration and the model. When this result occurs The most intuitive manifestation is that the snap ring cannot be fully seated. The two most common states are that the snap ring is too loose or the snap ring is too tight. Too loose a snap ring will lead to unstable retention of the removable partial denture and cannot meet the requirements. Functional requirements, and there is a risk of falling off, too tight a clasp will easily cause abutment pain, therefore, it is necessary to adjust the clasp to ensure the proper tightness of its retention

[0005] In view of the fact that there is no special snap ring adjustment tool in the prior art, the traditional snap ring adjustment method is usually manually adjusted through orthodontic pliers, which relies on the experience and techniques of technicians, and the stability and reliability are poor , it is easy to cause multiple adjustments that are not in place, and even cause the snap ring arm to break
