Use of cephalometric analysis for implant placement in a patient with an edentulous maxilla with a severe Class III intermaxillary relationship.
A patient with a totally edentulous maxilla and a seVere Class III intermaxillary relationship in the anterior region was treated by implants. In the mandible, there were 10 teeth between the second premolars. The inclination and width of the maxillary anterior residual bone were measured on cephalometric X-ray film obtained before treatment. The results of cephalometric analysis did not support clockwise rotation of the mandible or lingual angling of the maxillary anterior teeth by use of prosthesis to improve the Class III relationship. Ten implants were simultaneously placed in the maxilla. Then, a maxillary temporary full bridge was seated after reduction of the crown lengths of the mandibular anterior teeth. An apically positioned flap operation was performed to eliminate periodontal pockets and to obtain clinically suitable crown lengths of the mandibular anterior teeth. A noncemented, screw-retained maxillary full bridge and a conventional mandibular full bridge were placed. Postoperative cephalometric analysis showed that the outcome was clinically acceptable. The patient has been satisfied for more than 5 years since placement of the implant prostheses.
