Fused Cuspid and Bicuspid

relationship and such interference usually makes the condition worse. I have devised a procedure that corrects most of these cases, and as I have never seen a similar technic in the literature, I am presenting it here. An impression of the arch is taken with any of the hydrocolloid materials and a cast is made of any strong heat-resisting die ma terial. The porcelain teeth are removed from the partial denture by boiling in acid and the case is put on the model as well as pos sible considering its warped condition. It is then heated by a brush flame of a blow torch and, when thoroughly heated, is pressed into correct relation with a small instru ment. When it is in proper adaptation, the heat is gradually withdrawn to restore the temper. The idea is to apply the heat to the proper place on the partial denture to over come the “rock.” Usually, only one part of the partial denture is at fault, and a little study of the nature of the warped condition before the heat is applied will indicate just where the treatment should be applied. Many partial dentures that would other wise require recasting can be thus restored to useful service.

The observation and treatment of several hundred cases have taught me to give very careful attention to this condition, which is taken altogether too lightly as a comparatively harmless and socially accepted embarrassment. Ceremonial weekend events in college towns are followed by small epidemics of this disturbance.
