Simultaneous Replacement of Maxillary Central Incisors with CEREC Biogeneric Reference Technique: A Case Report

Blog Article

Biogeneric Reference Technique (BRT) of the CEREC 3D v.3.8 software is an effective technique for single anterior ceramic crowns because it provides computer-controlled match of the tooth form to the contralateral tooth.BRT also enables the fabrication of caruso milk thistle two or more anterior all-ceramic crowns simultaneously.This clinical report demonstrates the clinical application of BRT for designing and milling two central incisors in one appointment using a single optical impression.

After completing the virtual design of the first central incisor, it was copied and a mirror image was created.The second central incisor was designed using this replicated image and therefore a computer-controlled symmetry was obtained.The crowns were milled from monolithic feldspathic ceramic blocks and adhesively luted with dual-cured resin cement following dentin conditioning.At the two-year fp9550bk follow-up appointment, the restorations were intact, no adverse effects were noted, and the resultant appearance was highly satisfactory for the patient.A step-by-step protocol is described from design to cementation of these restorations.
