title: Making a maxillary record base with the dental surveyor.
abstract: A technique has been described that will allow more intimate contact of a maxillary record base to the tissues and the casts. A dental surveyor is used to determine a path of insertion that minimizes the amount of undercut to be blocked out. By coating the cast with tinfoil substitute prior to blocking out the posterior undercuts, the rope wax will adhere to the resin. On initial removal from the cast, the wax will yield enough to clear the undercuts. The wax in the anterior portion of the base will also flex enough to clear the undercut. The cast will not break, and maximum utilization of the labial vestibule will be realized. This technique produces a maxillary record base that is stable, retentive, and allows anterior teeth to be properly positioned without problems of resin interference.
