PRECISION DEVICE FOR ATTACHING REMOVABLE DENTAL PROSTHESIS

摘要

Patent of invention of a precision device for attaching removable dental prosthesis, designed for the upper and lower dental arch free ends, consisting of a fixed male member (1) and a removable female member (2), capable of absorbing, when engaged through an overlapping movement, all masticatory force due to gingival occlusive movement and therefore transferring it in a distributed manner over the mucous membrane on which the removable prosthetic portion is seated, this effect being caused by a dampening element (9) located in the male member (1), member (1) being made of a rigid material, of little thickness, formed in an approximately rectangular shape, there being two cavities (7 and 8) on one of its faces and there being another cavity (11) on the other face, there being, joined to cavity (8), a slit (10) which engages spring (9) inside said cavity (8); member (2) consists also of a hollow rigid material piece, whose inner shape is the same as member (1), there being on the inner walls of said member (2) two pins (12, 14) and a recurved pin (13), positioned so that, during overlapping movement for engagement, pin (12) engages cavity (7), recurved pin (13) engages through pressure spring (9) and pin (14) engages cavity (11) respectively.
