| Outline of Final Research Achievements |
It is reported that enamel matrix protein derivative (EMD) enhances periodontal regeneration and an optimal mechanical stress (MS) has a positive effect on bone healing. One-wall intrabony defects were fabricated in bilateral mandibular premolars in beagle dogs, and the premolars were moved into the defects using orthodontic devices. The present study evaluated the effects of MS, autogenous bone grafting (AG) and EMD on periodontal regeneration in the experimental model. Consequently, tooth movement occurred without any complications and the AG and EMD treatment provided more favorable periodontal regeneration characterized by new attachment in the defects when compared to AG alone. These findings indicate that the MS, AG and EMD treatment may be a new approach in periodontal regenerative therapy.
