ABSTRACT
Objective @#To establish an animal model that clinically conforms to the characteristics of severe alveolar ridge atrophy. @*Methods @#Beagle dogs were used as experimental subjects. Bilateral fourth premolars and first molars in mandible were extracted. A horizontal groove was made on alveolar ridge which was 8 mm from the cemento-enamal junction of mandible third premolar and second molar. Rongeur was used to remove the alveolar bone above this groove and bone chisel was used to level the bone-free area. A box-shaped defect cavity of the size 25 mm × 8 mm was formed with sterile silicone prosthesis implanted. After careful suture we waited for the subjects to heal naturally. Eight weeks after operation, CBCT examination was performed.@*Results @#Eight weeks after bone remodeling the top of alveolar ridge of operation area appeared to be a circular arc. The average distance from the bottom of the ridge to inferior alveolar nerve canal was 2.5 mm. @*Conclusion @#This study successfully established the Beagle dog animal model for severe alveolar ridge atrophy and laid the foundation for experiments on vertical bone augmentation.
