Abstract
|
|
|
|
Fabrication of dentures using CAD/CAM system has the advantage of reducing the number of patient visits and reducing errors during laboratory work. After the extraction of maxillary residual teeth, this patient changed to a completely edentulous state and the stability and retention of the existing mandibular complete denture were insufficient due to the absorption of the mandibular residual ridge, so the restoration of the mandibular implant retained overdenture and maxillary complete denture were planned. By digitizing the concept of BPS (Biofunctional prosthetic system) that uses the patient’s functional movement in closed mouth technique, the vertical dimension was taken by Gnathometer CAD and digital facebow transfer was performed using UTS CAD. In this case, fabrication of maxillary complete denture and mandibular implant-retained overdenture using monolithic disc and CAD/CAM system demonstrated favorable denture retention, stability, and support and the patient is satisfied with improved functions and esthetic of dentures.
