Of many methods of impression taking in the design of a complete denture, they can be roughly classified as pressure or strong and non-pressure or weak methods in terms of a degree of pressure exerted on the jaw membrane. In the design of a partial denture, particularly that of a free-end denture, a strong impression taking method is generally recommended for the reason that it decreases a burden on the part of clasp teeth and, inversely, increases a burden capacity of membrane beneath a plate, Although there is available a fair amount of published literature on this pressure impression taking method, they are devoted to the relationship between differen tmethods and jaw membrane, there being no report dealing with possible effect on the occlusal force and mastication subsequently. For this reason, in the present study the author was concerned with differences of impression taking pressure on the jaw morphology and occlusal force in the manufacture of a free-end partial denture whose burden is placed on the apical mucosa. For the prescribed purpose, 7 impression taking conditions were established for the determination of strong and weak pressure methods to be adopted. With a view to finding out what effect the differences in impression pressure would have on the jaw membrane and occlusal force as well, the membrane characteristics of a selected sample of 10 subjects consisting of 3 males and 7 females for whom a free-end partial denture was indicated were then measured.
