Three waxes technique for the check of the correct RP position
We can check the RP repeatability using the three waxes of reference position and therefore we can be sure of the correct positon on articulator between the upper and lower model.
We can check if the three waxes correspond removing the magnet from the split cast model; if at least two waxes give us the same position, we are sure that the position is correct: in fact it’s almost impossible that two identical waxes are wrong. Two equal waxes give us the certainty that the RP position of our models on articulator is correct.
