Abstract

The records of 23 patients who underwent mandibular second premolar enucleation in the early mixed dentition were studied. The patients were selected at random from a group which had mandibular plane angles in excess of 38 degrees to SN and had not worn headgear prior to mechanical orthodontic therapy. Pre- and posttreatment measurements were compared to measurements made in an earlier study by lsaacson et al.¹ and a significant decrease in lower anterior face height was found.

This paper was presented at the Biennial Meeting of the Edward H. Angle Society in September 1989 in Chicago, Illinois.
