The stresses generated to the supporting tissues during occlusal loading significantly influence on design
of denture and overdenture copings. The aim of this study is to compare the distribution of strains and
displacements on two different designs of copings of the partially edentulous mandible. The method for
full field measurement of strains and displacements is three-dimensional image correlation system
ARAMIS, that provides a synchronized stereo view of the specimen. The experimental models were
partially edentulous mandibles fabricated with SLA 3D printer Formlabs Form2 (Formlabs, Somerville,
MA) using standard grey dental model resin – the 1st one with conventional oval design of the copings
and the 2nd one with experimental design of circumferential milled copings. The most intensive
deformations were under working force of the maximum intensity of up to 1000 N. The crack of the less
displaced tooth model was recorded at 500 N. Displacement values of conventional oval... copings ranged
from -0.45 to +7.07 mm and for experimental copings displacements ranged from -0.01 to +0.54 mm.
Strains have shown that the maximum applied force at the final stage for conventional oval copings on
supporting surfaces resulted in maximal deformation for remaining incisor with 3.392% value, for canine-
0,515% and for premolar-3.391%, but experimental milled copings of remained incisor have maximal
deformation of 0.126% value, canine-0.102% and premolar-0.125%. Strains within the remaining teeth
roots were influenced by vertical displacement of the caps with particular sentence at the joint site of the
cap and the tooth substance.
