Medical exam and analysis
A complete diagnostic overview used to be carried out. This integrated intra-oral and extra-oral photographic documentation, medical exam of the laborious and cushy tissue, periodontal analysis, occlusal research and overview of the prevailing restorations.
The prevailing composite veneers exhibited marginal discoloration, floor roughness, chipping and insufficient anatomical shape. No secondary caries or pulpal pathology used to be detected. The periodontal tissue used to be wholesome, probing depths have been standard and there have been no indicators of irritation.
Occlusal research showed solid intercuspation and the absence of untimely contacts. Temporomandibular joint serve as used to be regarded as to be inside standard limits, and the affected person reported no historical past of ache or disorder. In response to those findings, the case used to be regarded as appropriate for conservative veneer substitute the use of a virtual workflow.
Remedy making plans
After the diagnostic section, an in depth remedy plan used to be formulated. The principle targets in changing the previous composite veneers have been to keep as a lot teeth as conceivable, fortify aesthetics and floor texture, deal with purposeful occlusion and entire the remedy in one consult with.
A number of restorative choices have been mentioned with the affected person, together with typical laboratory-fabricated ceramic veneers and chairside virtual restorations. After reviewing the benefits, boundaries, remedy length and prices, the affected person opted for a chairside virtual manner the use of 3-D printing. Knowledgeable consent used to be acquired, and expectancies referring to coloration, form and the overall end result have been mentioned intimately.
Enamel preparation
The prevailing composite veneers have been in moderation got rid of the use of fine-grit diamond burs beneath magnification. Minimum preparation used to be carried out in response to enamel-preserving ideas. The preparation design integrated mild facial relief of 0.3–0.5 mm, rounded line angles and lightweight chamfer completing strains. The preparation used to be restricted essentially to the prior to now restored spaces. The purpose used to be to maximize the teeth bonding floor and thereby make stronger long-term adhesion and medical longevity.
Virtual impact and smile design
After enamel preparation, the enamel have been wiped clean and remoted. A virtual impact used to be bought the use of an intra-oral scanner, generating high-resolution virtual fashions and getting rid of the desire for typical impact fabrics. The virtual recordsdata have been transferred to grin design tool, the place making plans used to be carried out. Enamel proportions, incisal edge place, smile line, midline alignment, buccal hall, gingival symmetry and facial solidarity have been evaluated and optimised.
A virtual smile design and digital restorative design have been generated to simulate the proposed restorations (Figs. 2a & b). The digital preview used to be offered to the affected person to visualize the expected end result. Minor adjustments have been integrated in line with the affected person’s comments, specifically referring to enamel period and contour. This collaborative manner higher affected person involvement and progressed remedy predictability.
