FEM model analysis of dentures silicon relining influence on the stresses redistribution in denture foundation soft tissues
Języki publikacji
Abstrakty
Urazy i odczucia dyskomfortu bólowego podczas użytkowania protez zębowych mogą powstawać w wyniku przekroczenia tolerancji tkanki zarówno na ciśnienie jak i ścinanie, których maksymalne wartości na drodze badań MES zlokalizowano we wzajemnie odległych obszarach. Wprowadzenie silikonowego podścielenia protezy skutkuje zmniejszeniem maksymalnych wartości nacisków i ich wyrównaniem na powierzchni przylegania. Jednak przeniesienie części nacisków na stoki bezzębnych wyrostków skutkuje zwiększeniem ścinania przy kości pod powierzchnią tkanki miękkiej.
Injuries and discomfort of pain sensations during wearing of dentures might result from exceeding tissue tolerances both as far as pressure and shear are concerned. Their maximum values determined by means of FEM analysis were located in opposite areas. Introducing silicone denture relining results in reduction of maximum compression values and their balance on adherence interface. Nevertheless, relocation of part of the compression forces on slopes of edentulous ridges causes increase of shear at the bone under surface of soft tissues.
