Review of the standard occlusal rim

抄録

Complete denture must have the proper morphology to restore or improve appearance and function. This requires fabrication of an occlusal rim with the correct maxillomandibular relation that is suitable for arrangement of the artificial teeth. However, current procedures require that the occlusal rim be modified several times in the patient's mouth, using considerable chair time. We reviewed how to properly establish the maxillomandibular relation for the edentulous patient and how to create the standard form of the occlusal rim for arrangement of the teeth. Further, we analyzed standard numeric values for the occlusal rim form.
We found significant differences at the 5% level between men and women for the mean of each measured value of the posterior teeth and the maxillary anterior teeth. In the anterior region we found significant differences at the 5% level in the dispersion of the measured values from flange and from the crest of the ridge. However, neither the age of the patient at the time of denture fabrication or the number of yeas the patient had been edentulous had any significant effect on the measured values.
