# Full Digital Workflow for Aesthetic Rehabilitation of the Upper Tenth: A Case Report
## 1 Introduction  
Recently, modern technologies have been introduced into dentistry. Computer design software has progressed into an effective means of treatment planning and communication between clinicians, patients, and dental technicians. Smile design can nowadays be performed with the use of digital technology, namely computer software such as PowerPoint (Microsoft Corp., Redmond, WA, USA), Keynote (Apple Inc., Cupertino, CA, USA), Photoshop software from Adobe Systems (San Jose, CA, USA), or digital smile design (DSD), combining digital photography and imaging software [1].  
Regardless of the system employed, the design should be based on macro- and micro-esthetics concepts [2, 3, 4]. Macroesthetics refers to the interrelationships between the face, lips, gingiva, and teeth, while microesthetics refers to the individual tooth. Both elements should be carefully considered and evaluated in order to create a harmonious and estheticsmile. The gummy smile and improper teeth shape are major patient concerns. The former is an undesirable relation between the length of the upper lip and the display of the gingiva and teeth. It can result from short teeth, passive eruption, gingival overgrowth [5], insufficient length of the upper lip, as well as hyper-elevation of the muscles of the upper lip [6; 7]. Crown lengthening can be utilized as a standalone aesthetic surgery to extend the clinical crown when the incisal edge location is ideal. Hence, crown lengthening along with restorative therapy is indicated when also the position of the incisal edges should be improved.  
Improvements in ceramics' physical and optical characteristics, as well as adhesive cementation techniques, have unquestionably made it possible to adhere to three crucial criteria: aesthetic, function, and bioeconomic principles. Ceramics have been employed because of their biocompatibility, biomimicry, lifespan, and excellent resistance, especially when reinforced with lithium disilicate [8; 9].  
It has turned out that the results are more predictable. According to [PERSON] et al. [10], the survival rate of porcelain veneers varied from 92% after five years to 64% at ten years. Through their 20-year retrospective analysis, [PERSON] et al. [11] calculated the 90% survival rate of porcelain veneers at 12 to 13 years.  
As long as the procedure is carried out in accordance with a precise treatment plan and a properly adhered-to protocol during the clinical and laboratory stages, lithium disilicate veneers provide good aesthetics with predictable and long-lasting outcomes [12; 13].  
Overall, tooth wear was considered as a non-carious loss of tooth structure. This irreversible phenomenon is the result of varied mechanisms like the dissolution of hard tissues with acidic constituents (known as dental erosion), contact with exogenous materials (known as dental abrasion), or tooth-to-tooth contact (known as dental attrition) [14]. These mechanisms often act in synergy or chronologically, which might increase tooth wear at a slightly young age [15]. This condition causes copious problems like increased tooth hypersensitivity, variations in the vertical dimension of occlusion with probable functional defect, pulp involvement, and possibly reduced aesthetic look [16]. To rehabilitate a worn dentition, ceramics can be used [17].  
The implementation of computer-aided design and computer-aided manufacturing (CAD/CAM) technologies can be utilized at the step of planning and treatment to provide predictable prosthodontic rehabilitation [18]. This article outlines a step-by-step process for diagnosing a patient with a gummy smile, treatment planning, and optimizing the final aesthetic result with the use of digital technology.
