Details and patient eligibility

About

Patients need laminate veneer for their teeth usually use Emax CAD as an etchable ceramic. Yet fracture may occur so a stronger material is needed. Vita Suprinity is a recent material with glass ceramic enriched with zirconia (approx. 10% by weight) that offer practices and laboratories a high-strength, zirconia-reinforced lithium silicate ceramic (ZLS) and can be used to fabricate laminate veneers but the investigators have to know clinically it is fracture resistance, so the investigators are going to have Parallel groups in a randomized clinical trial.

Enrollment: 16 estimated patients

Sex: All

Ages: 18 to 60 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

All subjects are required to be:

• From 18-60 years old, and able to read and sign the informed consent document.
• Physically and psychologically able to tolerate conventional restorative procedures
• Have no active periodontal or pulpal diseases, have teeth with good restorations
• Patients with teeth problems indicated for laminate veneer (e.g. discoloration, fracture not involve more than 50% enamel loss, mild malposition, ....)
• Willing to return for follow-up examinations and evaluation

Exclusion criteria

• Patients in the growth stage with partially erupted teeth
• Patient with fractured teeth of more than 50% enamel loss
• Patients with poor oral hygiene and motivation
• Pregnant women
• Psychiatric problems or unrealistic expectations
• Lack of opposite occluding dentition in the area intended for restoration
