Insertion axis in removable prosthesis: a preliminary report

For mobile partial dentures, respecting the insertion axis can improve the predictability of the periodontal tissue and the resistance of the remaining teeth with clasps. The drawing of an arrow in the model shows the insertion axis of the prosthesis. It would be desirable to include information regarding the insertion axis and advice for the management of the removable partial denture in the first days of use in the declaration of conformity given to the doctor and to thepatient, in the indications section. It can be said that correct insertion of the removable partial denture, helped by verbal and written instructions from the doctor, can reduce possible periodontal alterations of the remaining teeth, by eliminating spurious stresses during insertion and removal of the prosthesis.
