In this work, we calculated the masses of the ground and radial excited states of heavy tetraquarks in the framework of the nonrelativistic quark model for two wave states nS and nP. The potential used is the parabolic potential plus the spin term, and the method we used to solve the Schrödinger equation is the NU method. The Regge trajectories in the 
plane are linear and we obtained the parameters 
and 
for each state. The results are in good agreement with the available experimental data and we predicted the structures of tetraquarks X(4.500), X(4.700), X(4.740), X(6.900), X(7.200), Y(4.230), Y(4.660), and 
.
