| Abstract |
Previous studies have indicated that an injured condyle during adolescence is a causative factor for reduced mandibular growth and resulting asymmetry of the mandible. The aim of this study was to examine the nature of mandibular growth after unilateral condylectomy and to elucidate the effects of mandibular advancement. Sixty growing mice were subjected to unilateral condylectomy, and then one-half of them underwent treatment with a functional appliance. After 4 wks, a unilateral condylectomy produced reduced growth of the mandible and a subsequent lateral shift to the affected side. However, reduced growth and a lateral shift of the mandible were eliminated by a functional appliance, and prominent regeneration of the condyle was also demonstrated. It was shown that mandibular advancement provides for the regeneration of cartilaginous tissues on injured condyles and recovery of reduced mandibular growth, leading to correction of the lateral shift of the mandible.
