Role of special elements in countering the tipping of removable denture clasps

Abstract

Because the partially removable clasp prosthetic device is a unitary, rigid and undeformable construction, it’s subject to tipping because the segments opposite to the one we mobilize will move at the same amplitude but in reverse. This tipping, which is caused by the imbalance between resistance and solicitation on certain constructive segments of the partially removable prosthesis, is produced by rotation. To counter the tipping we have to solve two categories of issues: balancing the constructive ensemble of the partially removable prosthesis on the prosthetic field and equipping the partially removable prosthesis with special elements. Specific for countering the tipping is the way we place the support, maintenance and stabilization elements with anti-tipping effect. The technical solution for both category issues is removing the factors which determine the appearance of the tipping axis.
