ABSTRACT
This clinical report describes a digital workflow using the virtual smile design approach augmented with a static 3-dimensional (3D) virtual patient with photorealistic appearance to restore maxillary central incisors by using computer-aided design and computer-aided manufacturing (CAD-CAM) monolithic lithium disilicate ceramic veneers.

This clinical report proposes a digital workflow using 2-dimensional (2D) digital photographs, a 3D extraoral facial scan, and cone beam computed tomography (CBCT) volumetric data to create a 3D virtual patient with craniofacial hard tissue, remaining dentition (including surrounding intraoral soft tissue), and the realistic appearance of facial soft tissue at an exaggerated smile under static conditions. The 3D virtual patient was used to assist the virtual diagnostic tooth arrangement process, providing patient with a pleasing preoperative virtual smile design that harmonized with facial features. The 3D virtual patient was also used to gain patient's pretreatment approval (as a communication tool), design a prosthetically driven surgical plan for computer-guided implant surgery, and fabricate the computer-aided design and computer-aided manufacturing (CAD-CAM) interim prostheses.

Digital advances have changed implant planning to improve outcomes in placement and restoration. Layering multiple image inputs, such as volumetric radiology, photography, and 3-dimensional (3D) surface scans, has allowed better assessment of patients with partial or complete edentulism, and this can aid in producing 3D visual predictions, implant guides, and prosthetics to execute the proposed plan.

This article describes a digital workflow using cone beam computed tomography imaging as the primary diagnostic tool in the virtual planning of the computer-guided surgery and fabrication of a maxillary interim complete removable dental prosthesis and mandibular interim implant-supported complete fixed dental prosthesis with computer-aided design and computer-aided manufacturing technology. Diagnostic impressions (conventional or digital) and casts are unnecessary in this proposed digital workflow, providing clinicians with an alternative treatment in the indicated clinical scenario.

This clinical report describes the treatment of maxillary and mandibular immediate implant placement and immediately loaded implant-supported interim complete fixed dental prostheses with a contemporary digital approach. The virtual diagnostic tooth arrangement eliminated the need for a customized radiographic template, and the diagnostic data collection required for computer-guided surgery (digital diagnostic impressions, digital photographs, and a cone beam-computed tomography [CBCT] scan) was completed in a single visit with improved workflow efficiency. Computer-aided design and computer-aided manufacturing (CAD/CAM)-fabricated surgical templates and interim prosthesis templates were made in a dental laboratory to facilitate computer-guided surgery and the immediate loading process.

This article reviews the rationale, techniques, and advantages of a guided full-arch immediatefunction implant treatment modality that includes placement of a prefabricated, bar-supported, monolithic polymethyl methacrylate acrylic (PMMA) prosthesis for edentulous and terminal dentition patients. A case presentation depicting the protocol shows it to be an effective and predictable approach to providing fullarch immediate fixed teeth, particularly when compared to conventional denture conversion techniques.

Clinical digital photography adds an efficient, new dimension to the information provided to the dental technician. Through the use of digital photography, the clinician can create a series of images that communicate key prosthetic facial and dental landmarks for the dental technician to use in analyzing and creating the final prosthesis for the patient.
