Outcome Measures

Primary Outcomes (1)

  • Color match and stability

    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.

    24 months

Study Arms (2)

Prefabricated Composite Resin Veneers

EXPERIMENTAL

Participants received prefabricated composite resin veneer restorations for the treatment of anterior teeth requiring esthetic rehabilitation. Veneers were placed according to the manufacturer's instructions using a standardized adhesive protocol.

Other: Prefabricated Composite Resin Veneers

3D-Printed Composite Resin Veneers

EXPERIMENTAL

Participants received customized 3D-printed composite resin veneer restorations for the treatment of anterior teeth requiring esthetic rehabilitation. Veneers were fabricated using a digital workflow and cemented according to the manufacturer's instructions using a standardized adhesive protocol

Other: 3D-Printed Composite Resin Veneers

Interventions

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

Prefabricated Composite Resin Veneers

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

3D-Printed Composite Resin Veneers

Eligibility Criteria

Age20 Years - 40 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

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

You may not qualify if:

  • 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
