Precision and Planning in Aesthetic Dental Therapy: A Scoping Review

Abstract
Background: Aesthetic dental rehabilitation has come a long way. What was once driven largely by artistic instinct has grown into a structured, interdisciplinary field that leans heavily on modern technology. Digital tools have genuinely transformed how clinicians communicate with patients, collaborate with labs, and sharpen their diagnostic accuracy yet the field still struggles with real inconsistencies. There's no agreed-upon standard for measuring aesthetic
outcomes, diagnostic thresholds vary widely from one clinician to the next, and documentation practices remain all over the place. These aren't just technical problems. They reflect how differently clinicians perceive things, the cognitive shortcuts they rely on, and how much or how little they involve patients in decision-making. All of this makes a strong case for moving toward protocol-driven, evidence-based care.
Objective: This scoping review maps what the current research actually tells us about strategic treatment planning and precision aesthetic diagnosis in prosthodontics and restorative dentistry.
Methods: A comprehensive literature search was conducted across major indexed databases through 2025, following PRISMA-ScR guidelines. Studies were included if they covered digital dental photography, facial and smile analysis, midline orientation, axial inclination, gingival display, diagnostic wax-ups, intraoral mock-ups, provisional restorations, ceramic material selection, shade validation, try-in protocols, or cementation strategies.
Results: The evidence consistently shows that digital workflows especially digital photography and Digital Smile Design (DSD) meaningfully improve how repeatable the diagnostic process is and how engaged patients feel throughout treatment. Key aesthetic considerations like facial midline alignment, axial inclination, gingival zenith positioning, buccal corridor dynamics, and tooth proportions came up repeatedly across studies. Diagnostic wax-ups and intraoral mock-ups proved to be genuinely indispensable for confirming both functional and aesthetic results before committing to definitive treatment. Among restorative materials, zirconia and lithium disilicate offered the best balance of mechanical strength and optical quality. That said, inconsistent clinical decision-making and a lack of standardized outcome reporting still limit how widely these findings can be applied in practice.
Conclusion: In prosthodontics, predictable aesthetic outcomes come from a structured, protocol-driven process that weaves digital tools together with a solid foundation in biology, occlusion, and material science. Future research should focus on multi-center comparative designs and adopt standardized outcome measures both clinician-and patient-reported to meaningfully advance evidence-based practice.
