Precision attachment lock apparatus and method of locking a dental prosthesis in mouth

摘要

The invention is the precision attachment lock apparatus for use in in-mouth removable (partial-metal) dental prosthesis with extra coronal application in the field of dentistry and having female moulded framework dental prosthesis apparatus (2) connected with the denture; and male moulded crown apparatus (3) connected with the implant or natural (fixed) tooth, and it comprises attachment apparatus (1), which forms the centre of the precision attachment lock apparatus (4), is connected between the framework dental prosthesis apparatus (2) and the crown apparatus (3), and comprises housing (1.4) having recession (1.21), protrusions (1.22), and bearing surface (1.41) at its outer surface and performing locking due to its form; framework dental prosthesis apparatus comprising attachment apparatus housing (2.3) having recession (2.31) and protrusions (2.32) equivalent to the outer surface form of the attachment apparatus (1) providing locking of the attachment apparatus (1); and lock member (3.3), which is formed equivalently to the housing (1.4) found on the attachment apparatus (1) and fits in the housing (1.4), and which has concave surfaces (3.31) on the crown apparatus (3) providing locking-in of at least two adjacent teeth by performing locking of the framework dental prosthesis apparatus (2) connected with the artificial teeth and the crown apparatus (3) connected with the fixed teeth.
