Abstract
Patient: The patient was a 71-year-old female who visited our hospital with chief complaints being esthetic impairment and masticatory disturbance due to a defect of the upper right first premolar. The 90-degree twisted prosthetic morphology of the upper right second premolar was modified, and the occlusal pattern led by the canine was conserved using an implant. For the defect of the upper right first premolar, a bridge was selected in consideration of the adjacent tooth condition to establish a stable oral cavity environment.
Discussion: The prosthetic restoration method was selected by accurately identifying the risk of occlusion of the residual teeth and periodontal condition.
Conclusion: The residual tooth conditions were accurately identified, prosthetic treatment with implants and bridges was applied to defects of the bilateral teeth, and stable therapeutic results were achieved on both sides.
