The transfer of information such esthetics and occlusion from the preoperative to the postoperative digital impression could reduce the time needed to build an immediately loaded full-arch not-guided rehabilitation and improve the quality of the immediate interim restoration. Based on the digital technology advances of the last years, the purpose of the present clinical report is to describe a novel digital workflow based on computer-aided design and computer-aided manufacturing aimed at fabricating an interim fixed full-arch restoration. The protocol entails recording preoperative information such as esthetics, the occlusal plane and the intermaxillary relationship in implant-supported complete rehabilitations before the surgical insertion of the fixtures. Then, the information is transferred to the postoperative impression using a digital index in the lower jaw and the palatal rugae in the upper jaw. Within the inherent limitations of a case report, the workflow was accurate, predictable, without errors from conventional protocols and was apparently characterized by low biological costs.

SUMMARY The purpose of this case report was to present the use of a contemporary digital photograph–assisted virtual smile design principle, an intraoral digital impression, and computer-aided design/computer-aided manufacture–fabricated lithium disilicate ceramic veneers to treat a patient with esthetic needs in the maxillary anterior region. By using the proposed digital restorative work flow, this case report demonstrated an effective communication pathway between the patient, clinician, and dental laboratory technician. Effective communication can help to achieve a more predictable and satisfactory esthetic outcome.

Occlusal contact loss occasionally occurs following the placement of implant-supported fixed dental prostheses in the posterior region. This complication is caused by the change in the vertical dimension of occlusion after the recovery of mastication. The change is probably related to the prosthesis sinking phenomenon and previous mandibular dislocation. The use of interim prostheses could help re-establish the vertical dimension of occlusion. The definitive prostheses can then be accurately fabricated using digital techniques in the newly established vertical dimension. In this case report, we introduce a protocol incorporating a computer-aided design and computer-aided manufacturing (CAD-CAM) interim prosthesis and digital techniques to minimize the occurrence of unexpected initial occlusal changes in the prosthetic treatment of implant-supported prostheses in the posterior region.

This clinical report describes a digital process of using a 3-dimensional (3D) virtual patient at an exaggerated smile view for the pre-treatment simulation of the prosthetic outcome. In addition, the virtual patient can be used to assist with the formulation of a prosthetically - driven surgical plan for static computer-aided implant surgery (s-CAIS) and the design of the computer-aided design and computer-aided manufacturing (CAD-CAM) prostheses.

SUMMARY Interdisciplinary treatment planning is necessary in certain clinical situations to optimize esthetic treatment outcomes. Patients presenting with severe wear of their anterior teeth from iatrogenic influences pose a particularly difficult problem in terms of esthetic treatment planning. Collaboration of practitioners from the disciplines of orthodontics, periodontics, and restorative dentistry is essential for the treatment of patients with complex esthetic dental needs. Careful assessment of clinical situations and corresponding specialty consultations are of utmost importance to achieve more predictable and esthetic treatment outcomes. The purpose of this clinical case is to report to the readership a novel digital fabrication of computer-aided design/computer-aided manufacturing milled acrylic provisional restorations and final lithium disilicate definitive restorations after orthodontic and periodontal therapy with virtual master impressions, casts, and articulation.
