## 4 Discussion  
Novel technologies have been widely used in dentistry for diagnosis, treatment planning, and execution of medical and dental care [21; 22; 23]. The scanners' advantages are expediting results; improving patient comfort; avoiding traditional impressions and materials and pouring stone models; better patient, technician, and clinician communication; simplifying clinical procedures; and predictable results [24; 25]. However, oral health providers must be aware of all the steps needed whenever novel technology is implemented in daily practice. This report could be useful to clinicians as it described all the clinical steps involving a facial scanner and IoS for the diagnosis, treatment planning, and execution of a FMR with zirconia fixed restorations. In fact, this is the first case report to comprehensively describe a technique integrating facial and dental scanners for the treatment planning and execution of milled zirconia partial restorations, single crowns, and fixed dental prostheses with an initial loss of VDO and crown lengthening. Diagnostic wax-up is an important step in full mouth reconstruction and can now be done digitally to have a full digital workflow. Wax-up is critical because it provides the patient's occlusion scheme, contact numbers, and contact areas. The shape of the restoration is critical for the static and dynamic occlusal relationship because it influences chewing efficiency, restoration longevity, and the patient's comfort [26; 27; 28]. Studies have evaluated the effect and accuracy of traditional and digital wax-up and the results show positive outcomes for full digital workflows. A recent study evaluated the geometric effects of conventional versus digital prosthodonic wax-ups in relation to the lateral occlusion scheme with excursive movements with 0.5, 1.0, 2.0, and 2.0 mm from the maximal intercuspation position and the results displayed similar values with no differences between conventional and digital prosthodonic planning [29]. Another study also evaluated the morphological symmetry for maxillary anterior teeth before and after prosthodonic planning with traditional and digital wax-ups on 13 patients, and the study concluded that digital wax-up provided greater single tooth symmetry than the traditional wax-up and anterior segment teeth were minimally affected by either digital or traditional wax-up [30]. The digital workflow presented in this report included digital wax-up and provisional fixed restorations were fabricated based on it. Then, the provisional restorations were placed intraorally, and occlusion, protrusion, lateral movements, smile, lip support, phonetics, and esthetics were evaluated. Indeed, the result's fulfilled the patient's demands, which was evidenced by her self-reported satisfaction despite her high pre-operative expectations. The authors acknowledge the challenges in the management when patients have high expectations prior to treatment. Hence, adequate communication must be established with patients to understand better their needs and objectives bring their expectations closer to reality and avoid potential misunderstandings. It should be acknowledged that not every dental clinician is a match for every patient, as not every patient is a fit for every dentalprovider. Effective verbal and written communication are key in every prosthodonic plan which involves patients with high esthetic demands and who consider they are doing a substantial financial investment in their full mouth rehabilitation. The reader is referred elsewhere to gain a deeper understanding of their patient's needs, wants, and sweet balance between expectations and satisfaction inspired by consumerism-based theories [31; 32; 33; 34]. Aspects regarding maintenance are an often-neglected topic of conversation. However, this aspect will secure long-term satisfaction with the therapy provided.
