In this paper we will report a case of maxillary protrusion with severe periodontitis and mental retardation, good results were obtained by comprehensive treatment, including orthodontic treatment. A 33-year-old female with the chief complaints of pathologic teeth mobility was diagnosed as severe generalized chronic periodontitis, maxillary protrusion, the proclined maxillary anterior teeth, spaced arch and deepbite. This patient had finished the initial periodontal therapy before orthodontic treatment. Considering decreased alveolar bone height, the upper and lower dental arches were aligned with light force and using temporary anchorage devices for retraction. The extrusion of the incisors and the mesial movement of the molars were avoided. The orthodontic treatment lasted for 2 years and 6 months. The maxillary teeth were fixed by prosthetic restoration as the permanent retention. 8 years after retension, fine occlusion is obtained.
