Abstract: This case aims to achieve functional oriented oral rehabilitation with implants based on integrated digital technology. The patient wore splint to restore masticatory function and parafunction were controllable. The position,direction and dimensions of the implants were designed taking into the consideration of contact point on occlusal surface, axial direction as well as bone volume. Treatment guide was printed under full digital workflow for implant placement and immediate loading. Six months later, occlusal data was obtained using facial scanner and jaw movement record system and then mounted on full adjustable articulator. Ttitanium framework and ceramic crown was fabricated after Wap-up designing process. In this case, function oriented implant placement and restoration was done effectively with fully digital work flow. Clinical outcome of occlusal rehabilitation was evaluated with T-scan and masticatory efficiency tester. Parafunction like bruxism was monitored closely. This method quantifies implant-supported reconstruction, which can better realize the patient's aesthetics and chewing functions, but it still needs further research on the accuracy of the digital production of the prosthesis.
