[Importance of vertical discrepancy on subgingival position of the crown margin]

The goal of work was in detecting the existence and the size of vertical discrepancy of subgingival positioned edge crown in extracted teeth. Value of the vertical discrepancy had been measured on extracted teeth with artificial crowns which were founded in the patient's mouth and were extracted with the artificial crown. On the teeth that were included in the research was measured the value of the vertical discrepancy on the demarked line. The measurement was enabled on the specialized measure in the Zavodima za mjerenje Vazduhoplovnog zavoda "ORAO" Rajlovac Sarajevo. Value measured vertical discrepancy on the teeth of the control group is shown in a table. It was measured if there was any significant statistic difference in discrepancy of the teeth in the group measured on the same surfaces (B) buccal, (O) oral, (M) mezial, (D) distal. X2 test was measured for all the surfaces B, O, M, D on all teeth. On the extracted teeth with the artificial crowns appears vertical discrepancy.
