[Classification of periodontologically indicated vestibuloplasties].

The present paper deals with periodontologically indicated vestibule deepenings. For the first time, a grouping of the vestibule deepenings has been elaborated that comprises all fundamental possibilities of plastic-surgical intervention. This grouping gives a survey and a classification of the different methods of operation (in part designated by the names of the respective authors) and permits to trace back many methods to a fundamental principle whereby the number of seemingly different techniques of operation is reduced.
