[Dean's alveolotomy for the correction of maxillary protrusion with periodontal disease]

The method of intraseptal alveolotomy which was introduced by Dean and has meanwhile been further improved, enables us to correct maxillary protrusion when teeth cannot be retained. The various phases of the operation are described on the basis of our own experience. In many cases an additional excision of the labial frenulum with partial extension of the vestibulum appears to be indicated. This should, however, be performed in a second operation. Special attention is called to the simultaneous correction of a deep bite in the lower anteriors which is frequently the cause of periodontal damage of the maxillary teeth.
