The patient came to improve the esthetics of the upper prosthesis made 15 years ago. It is a screw-retained metal-ceramic prosthesis where the vestibular emergence of the implants in 16, 13 and 23 makes it difficult to predict satisfactory esthetics. The treatment is proposed using the BHS30 solution by angling the retaining screws in positions 16, 13 and 23 and by casting the metal framework using the 30° angled BHS30 castables.


a. Initial situation of the prosthesis, with severe esthetic and functional compromise, given the wear and misalignment of the structure.


b. After removal of the initial prosthetic structure, an analysis of the emergences is performed, contrasted by the direction of the abutments and castables in the model.


c. Correction of compromised emergencies with BHS30 calcinable cylinders angled at 30º.


d. Fabrication of the cast prosthetic structure and verification of the fit of the work, on the model and in the mouth.


e. Anatomy modeling on the structure and bisque tests.


f. Appearance of the prosthesis once glazed and with definitive staining, and placement protocol using the BHS30 system.


g. Operative placement and application of torque on the retaining screws for the fixation of the structure in the mouth.


h. Detail of the adjustment and vestibular emergencies of the corrected implants and final result, with esthetic and functional success, with significant improvement of the patient’s smile line.
