[Multi-source data acquisition technology in the restoration of the complete denture restoration]

In complete-denture restoration of edentulous jaws, the following information is needed: functional impression of edentulous jaws, jaw relationship and facial fullness, parameters of individual mandibular movement, etc. Traditional clinical methods in obtaining these data, which depend greatly on practitioners' clinical experience and skills, are subjective, complicated and low efficient. With the development of the digital restoration of edentulous jaws, a variety of equipment for three-dimensional scan have been applied in acquiring three-dimensional source data concerning the needed information, which greatly simplifies the process of data obtaining, reduces the dependence on operational skills and subjective experience, improves efficiency and efficacy of diagnosis and treatment, and standardizes the restoration process.
