Sažetak
The report she ds light upon the problem of the occlusive support as a means for transmitting pressure onto the remaining teeth when partial prosthesis is used. Rigid cast occlusive supports burden only the dental carriers owing to the biological difference between periodont and mucosa, while the mucosa beneath the faddle of the prosthesis recedes from it concurrently with physiological resorption. This biological difference is neutralized by means of elastic occlusive supports if their elasticity is adjusted in proportion to the resilience of the mucosa. According to the authors occlusive supports can be construyted from double bent wire whose diameter was brought to conform with the resilience of the mucosa by exact measurements.
The solloing problems were studied: a) the quality of the wire, b) the lenghth of the occlusive support, c) the diameter of the wire, d) the angle at which the horizontal arm is bent. The wires of different diameter made of stainless steel wire in use i nroutine practice were measured. The elasticity of the wire was measured on the measuring machine at the Institute of Mechanics at the Superior Technical School in Zagreb. The obtained results and the module of elasticity give directions for the correct manufacture! of the horizontal occlusive support and for the angle at which the wire vas to be bent. The thickness of the wire is adjusted to the module of elasticity.
