[Digitization-integrated strategies of simultaneous restoration of remaining natural teeth and implant restorations in invasive fixed occlusal reconstruction of dentition defects].

The minimally invasive fixed occlusal reconstruction of dentition defect is a sequential reconstruction process involving the minimally invasive restoration of the remaining natural teeth, the implant restoration of edentulous areas and the occlusal change from reversible to non-reversible. The simultaneous completion of minimally invasive natural teeth restorations and implant-supported crowns or bridges in an ideal occlusal design shows the obvious advantages of digital integration. The use of digital technologies such as intraoral scanning, kinematic face bow, virtual articulator and computer aided design and computer aided manufacturing (CAD/CAM), could be integrated in each stage of occlusal reconstruction, including the overall documentations and assessments before the restoration, the determination of the functional restoration space, the precise design and fabrication of the provisional and final restorations taking into account both esthetics and function and the preservation of the follow-up documentations and assessments after the restoration. The integration process can optimize clinical process and improve restoration accuracy. This article briefly describes the concept of minimally invasive occlusal reconstruction of dentition defects and the integration strategy of digital sequential restoration.
