Key and key way type attachment denture retention structure

Abstract

The invention relates to a key and key way type attachment denture retention structure, and belongs to the technical field of devices or methods of oral cavity or tooth sanitation. The key and key waytype attachment denture retention structure comprises a dental crown part and a key way part. The dental crown part is composed of an artificial dental crown, a key body and a key body substrate. Thekey body is located on the side face of the artificial dental crown, and the key body substrate is located at the position, on the gum square bottom face of the key body, of the side face of the artificial dental crown. The key body, the artificial dental crown and the key body substrate are in integrated forming connection pairs. The part, exceeding the key body, of the key body substrate is used for supporting the key way part, the width of the part accounts for 80% to 120% of the width of the bottom face of the key way part, and the thickness of the key body substrate is 0.5 mm to 1.5 mm.The key way part nests the key body, and is cooperatively connected with and fixed to the key body. The key and key way type attachment denture retention structure has the advantages that the key bodywith a zirconium dioxide material and the butment artificial crown integrally formed is provided, and the key body structure is improved; by means of the design that the key body substrate is additionally arranged on the gum square bottom face of the key body, the strength of the key body is improved, the key way is prevented from sliding down, and a false tooth is effectively stopped from sinking.

Description

technical field [0001] The invention relates to a plug body plug-way attachment denture retention structure, which belongs to the technical field of oral or dental hygiene devices or methods. Background technique [0002] Dentition defect is a common clinical oral disease. The loss of teeth in patients results in impaired masticatory function, which in turn affects the patient's digestive system and general condition. For the restoration of missing teeth, methods such as removable partial dentures and implant dentures are often used clinically. Traditional removable partial denture repairs often have adverse reactions such as warping, swinging, and mucous membrane compression. A clasp is required, which affects the appearance, and the denture is large in size and poor in comfort. The cost of implant denture restoration is high, or the condition of the patient's jaw is poor, and it is impossible to implement implant surgery. The bolt-type precision attachment retention devi...

Problems solved by technology

[0004] The production steps of the existing plug-type retainer are complicated, and the requirements for clinical and technician operations are high, and the production of the plug body is limited to metal materials

Figure 13A and Figure 13B It shows that there are defects in the existing structural design, in which the neck stress of the plug body is very concentrated, and the structure of the plug body is relatively weak, so it is easy to break after a long period of use; at the same time, after wearing the denture for a period of time, because there is no blocking structure, The plug channel often slides down along the longitudinal direction of the plug body, causing the denture to sink and compress the gums, which in turn causes adverse reactions such as redness, swelling, ulcers, and pain in the gums
