Embodiment Construction

[0026] like figure 1 As shown, the present invention provides an adjustable artificial dental crown 1, and the dental crown 1 can be a dental implant crown, or a dental post crown. Figure 1-Figure 3 The structure of the dental crown of the dental implant is shown. The side wall of the dental crown 1 is provided with an accommodation groove 2. The accommodation groove 2 has an upper opening 21 and a side opening 22. The upper opening 21 is located at the top of the dental crown 1, and the side opening 22 Located on the side wall of the dental crown 1, a detachable inlay 3 is arranged in the accommodating groove 2 or filled with a filling material. When food impaction occurs to form interdental gaps, the inlay 3 in the accommodating tank 2 can be taken out from the upper opening 21 and replaced with a larger inlay; or the accommodating tank can be filled with filling materials.

[0027] Wherein, the width of the bottom wall 23 of the accommodating groove 2 is the width of the ...

Abstract

The invention provides an adjustable artificial dental crown, an implant tooth and an artificial dental crown restoration method. An accommodating groove is formed in the side wall of the dental crown; the accommodating groove is provided with an upper opening and a lateral opening; the upper opening is positioned in the top of the dental crown; the lateral opening is positioned in the lateral wall of the dental crown; a dismountable embedding body is arranged in the accommodating groove or filling materials fill the accommodating groove. The adjustable artificial dental crown provided by the invention has the advantages that the restoration can be performed without dismounting the original dental crown; the problem of food impaction can be solved; a restoration body cannot be destroyed.

Description

technical field [0001] The invention relates to an adjustable artificial tooth crown and a dental implant, belonging to the technical field of medical treatment. Background technique [0002] Artificial dental crowns are usually divided into metal full crowns, metal porcelain crowns, all ceramic crown restorations, metal fused to plastic crowns, etc. The connection methods of the implant superstructure are divided into: screw retention, adhesive retention, and integrated crown. For dental implants, due to the displacement of natural teeth over time, loosening or defect caused by periodontitis, gaps will gradually develop in the proximal surface, resulting in food impaction, food impaction is considered to be the most common complication after fixed tooth restoration one. Long-term food impaction can easily cause damage to the tooth body and periodontal tissue, as well as peri-implantitis and alveolar bone resorption, which will adversely affect the long-term stability and ...
