[Performance of various prepared abutment forms. Posterior fixed bridge abutment].
The clinical techniques of the students were examined by analyzing the results of some measurements on the side wall inclination as a width and height of the full formed abutment of posterior fixed bridge, and the results of full covered crown data were compared. Significant differences in the inclination degree to the axis between upper and lower were not noticed in either premolars or molars on the mesio-distal side wall and bucco-lingual side wall, and were noticed between premolars and molars of the same jaw on both side walls. Margin diameter and height of diameter of the premolars showed a closer rank correlation than molars in mesio-distal side wall, but in bucco-lingual side wall, molars showed a closer rank correlation than premolars.
