Aesthetic rehabilitation for anterior edentulous spaces: The techniques and rationale for the use of temporary acrylic resins supported by CAD/CAM techniques in aesthetic emergencies

The present case report describes our approach to the management of the anterior edentulism treating the patient with the provisional PMMA made with the CAD/CAM technique at the aesthetic emergency. The patient’s problem meant that tooth 1 had to be removed. 3 from the upper anterior arch and, with regard to the aesthetics, a custom provisional restoration option was selected. The restoration was designed with retention arms provided with retention holes sufficiently to provide adequate extent of fixation of the adhesive composite and was maintained in sterile condition for three weeks until the dental implant was done. Stressing that although adhesion problems are inherent to PMMA materials, CAD/CAM technology and the use of innovative adhesive systems ensure that esthetic and functional solutions can be achieved in cases of emergency esthetic rehabilitation, it states that it can be a reliable and esthetic provisional restoration in a short time. Based upon the findings of the present study, a combination of modern techniques can be seen to be beneficial for using PMMA as a provisional material in certain clinical situations.
