The dental prosthesis for artificial anterior tooth, comprising an adjusting mechanism capable of adjusting the free vertical movement and the free horizontal movement of said occlusal surface portion, which is set up between a connecting portion and a dental corona.

The dental prosthesis for artificial molar tooth, comprising an adjusting mechanism capable of adjusting the position of said occlusal portion, which has at least one of the functions capable of adjusting at least one of movements including vertical, horizontal, and/or oblique movement of the occlusal surface portion, which is provided between the occlusal surface portion receiving the occlusal pressure, and the connecting portion connected firmly to the alveolar portion of a denture base.

The dental prosthesis for artificial molar tooth, comprising an adjusting mechanism capable of adjusting freely the vertical, horizontal, and/or oblique movement of the occlusal surface portion, and a stress breaking layer, made of pressure buffering materials capable of elongating and shrinking smoothly, which are set up between the connecting portion receiving directly said occlusal pressure, and the connecting portion, where said occlusal surface potion is capable of moving or sinking downwards by deforming itself elastically, and moreover said adjusting mechanism can be adjusted while the client rests, thus allowing the position of said occlusal surface portion to be properly adjusted.

The dental prosthesis for artificial anterior tooth, comprising a stress breaking layer, made of pressure buffering materials capable of elongating and shrinking smoothly and an adjustment mechanism configured to adjust the strength of a spring thereof, which is set up between the connecting portion, connected firmly to the alveolar portion of a denture base, and the dental corona, where said dental corona is capable of moving and sinking downwards when it receives said occlusal pressure as said stress breaking layer deforms itself elastically.

The dental prosthesis for artificial anterior tooth, comprising an adjusting mechanism allowing the position of the dental corona to move vertically, horizontally, and/or obliquely, and at the same time being adjustable by an operation from the outside while the client rests, which is provided between the connecting portion, connected firmly to the alveolar portion of a denture base, and the dental corona.

The dental prosthesis for artificial anterior tooth, comprising a stress breaking layer, made of pressure buffering materials capable of elongating and shrinking smoothly, and an adjustment mechanism capable of free-moving including vertical, horizontal, and/or oblique movement, and furthermore adjusting the position of the dental corona smoothly while the client rests which are provided between the connecting portion connected firmly to the alveolar portion of a denture base, and the dental corona, where said stress breaking layer, made of pressure buffering materials capable of elongating and shrinking smoothly, deforms itself elastically, thus said dental corona is able to sink downwards when it receives said occlusal pressure of said artificial molar tooth.
