Adhesive Cementation Materials and Techniques in Aesthetic Dentistry

March 31, 2026 updated by: Mara Gaile, Riga Stradins University

Adhesive Cementation Materials and Techniques in Aesthetic Dentistry and Their Effect on the Longevity of Porcelain Veneers

AIM: To determine the most effective cementation method and resin cement material for long term success of esthetical restorations TASKS: 1. Compare Panavia Veneer LC (Kuraray Noritake) cement with universal Panavia V5 (Kuraray Noritake) cement for porcelain veneer cementation in terms of marginal defects and discolouration; 2. Evaluating direct vs indirect restorations after 1-year and 3-year follow up periods in terms of patient satisfaction (evaluated by OES scale).

MATERIAL AND METHODS: Participants: Patients attending the Department of Prosthodontics at the RSU Institute of Stomatology, and willing to improve the aesthetics of front teeth with porcelain veneers. Approx. 30 patients. Inclusion criteria: healthy periodontium, needs 4 veneers, stable occlusion. Exclusion criteria: heavy bruxism, poor oral hygiene, active periodontal inflammation.

Veneer preparations will be done for maxillary anterior teeth approximately 0.5mm deep, involving the whole facial surface and keeping enamel around all borders. For digital impressions of preparations intra-oral scans with intraoral scanner (3Shape TRIOS 5 WIRELESS, Denmark) will be taken. Veneers will be fabricated according to the CAD/CAM technique. This will be a prospective paired design study, i.e., two different composite cements (Panavia V5 and Panavia Veneer LC) will be used for each patient, cementing two veneers with each of the cements.

Data on following variables will be collected:

  1. Restoration condition (defects related to restoration - ceramic fractures, cracks, loss of retention, discolouration);
  2. Condition of the abutment teeth (secondary caries, endodontic complications);
  3. Periodontal condition (probing depth, bleeding on probing, gum recessions);
  4. Patient satisfaction questionnaire (OES).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Patient satisfaction with porcelain veneers vs direct composite restorations using OES (orofacial aesthetic scale)
Time Frame: 6 months, 1 year, 3 years
OES is a questionnaire with 8 questions regarding orofacial appearance. The higher the score, the more satisfied the patient is. 7 questions evaluate specific items, and number 8 is an overall assessment.
6 months, 1 year, 3 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Comparison of 2 veneer cements in terms of complications and discolouration
Time Frame: 6 months, 1 year, 3 years

Data on following variables will be collected for all abutment teeth:

Restoration condition (defects related to restoration - ceramic fractures, cracks, loss of retention, discolouration; if present, calculated as a percentage from total restorations); Condition of the abutment teeth (secondary caries, endodontic complications; if present, calculated as a percentage from total restorations); Periodontal condition (probing depth in mm, bleeding on probing present or no; gum recessions in mm);
6 months, 1 year, 3 years

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Success and survival of porcelain veneers
Time Frame: 6 months, 1 year, 3 years

Success - veneer is present with no biological, technical or aesthetic complications. It is functional, stable, and free from disease. Calculated in percentage from the total count of cemented veneers.

Survival - restoration that remains in the mouth and is functional at the end of a specific observation period, regardless of its health status or complications. Calculated in percentage from the total count of the veneers.
6 months, 1 year, 3 years
