Case Study: Placing Veneers without Dental Preparation

Case Description: A 36-year-old male patient came to my office for a dental evaluation because he wasn’t satisfied with his smile. He was interested in a smile design but didn’t want any preparations on his existing teeth. 

When performing the clinical examination, I observed diastemas in the anterior sector with irregular incisal edges. Clinical photographs and study models were taken for diagnostic waxing. 
A silicone key was made with the diagnostic wax-up to determine the space available for veneers without dental preparation. A vestibular space of 0.5 mm in the middle and incisal third and of 0.2 to 0.1 mm in the cervical third was observed. I chose a resin composite as the restorative material for this case because it allows layers of this thickness in the cervical without affecting its mechanical properties. The resin composite also allows you to avoid over contouring the material, which can cause periodontal issues. I chose to use the indirect technique because it presents better mechanical behavior. Once the patient approved the diagnostic wax-up, a final impression was taken, a die model was made, and the color was selected. I then manufactured the restorations on the model.
