Dental implants are similar to real teeth, but they are not real teeth. The periodontal membrane has a certain sensory and cushioning function, while the implant root is closely integrated with the alveolar bone, and there is no physiological periodontal membrane structure in the middle, so there is not much cushioning function. The restoration process of dental implants is slightly different from artificial tooth restoration, so dental implants are similar to real teeth, but not real teeth.
