About this study

Dental veneers are now a commonly used conservative treatment to improve the appearance and functionality of anterior teeth that have enamel flaws, diastemas, small abnormalities, and discoloration. Compared to ceramic veneers, composite resin veneers have a number of benefits, such as requiring less tooth preparation, being less expensive, being easier to repair, and requiring less chairside time. Recent developments in composite resin technology and adhesive dentistry have further enhanced their mechanical qualities, wear resistance, and aesthetic results, making them a desirable treatment option for patients and professionals alike. There is little clinical data that directly compares the long-term performance of prefabricated and 3D-printed composite veneers, despite their growing use. The majority of research that is currently available has either examined each technique separately or has concentrated on laboratory assessments of mechanical properties. As a result, there is still not enough data to compare their clinical behavior in intraoral settings.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Good oral hygiene and satisfactory periodontal health
  • Patients requiring esthetic rehabilitation of anterior teeth
  • Presence of enough enamel for bonding

Exclusion criteria

  • Non-vital teeth or teeth requiring endodontic treatment
  • Severe malocclusion or parafunctional habits (e.g., bruxism or clenching)
  • Patients with severe intrinsic discoloration requiring alternative treatment

Treatment and study plan

Prefabricated Composite Resin Veneers

Other

Prefabricated composite resin veneer restorations used for esthetic rehabilitation of anterior teeth. Restorations will be bonded following the manufacturer's recommended adhesive protocol.

3D-Printed Composite Resin Veneers

Other

Customized 3D-printed composite resin veneer restorations fabricated using digital design and additive manufacturing technology and bonded according to the manufacturer's recommended adhesive protocol

Primary outcomes

  1. Color match and stability

    Time frame: 24 months

    Clinical evaluation of color match and color stability will be performed according to the World Dental Federation (FDI) evaluation criteria by two calibrated evaluators at baseline and at 6, 9, 12, and 24 months. Veneer restorations will be assigned FDI scores ranging from 1 (clinically excellent) to 5 (clinically poor). Clinical success will be considered as scores of 1-3 and failure as scores of 4-5. Assessment will be carried out under standardized lighting conditions using visual examination and magnification. Statistical analysis will be performed to compare changes over time and between the two study groups.
