[Posterior palatal sealing in Hungarian dental practice]. / A pharyngealis lezárás kialakítása a hazai gyakorlatban.

The purpose of the survey was to receive data about the methods, materials and instruments used in the development of the border seal at pharyngeal region. The problem concerned how the theoretical principles are realised in the everyday practice. A questionnaire consisting of 10 questions was given out to 35 dental laboratories in 31 towns of the country. 33 completed forms were returned. On the basis of the survey's results the authors conclude that in everyday practice practically nothing realizes from the recommendations of dental literature. The shape of the upper complete dentures' palatal seal is made by dental technicians, regretfully without the cooperation of dentists and what is more disappointing without their instructions. Dental technicians are left to their own resources to form the pharyngeal seal by mechanical engraving of the casts.
