The elective retention of vital roots for alveolar bone preservation: a pilot study.

A technique for retaining alveolar bone beneath complete dentures involving sumergence of vital canine roots below the level of the alveolar bone is reported. Early or late complications occurred in five of the eight roots retained. Radiographic and histologic examination showed the continuance of pulpal vitality and an absence of resorption of roots during the test period. The clinical at the end of 20 months' observation indicated that the procedure may provide a practical means of retaining alveolar bone for some individuals.
