Abstract
Introduction: The direct–indirect composite veneer technique was introduced in the 1990s as a means to heat-temper composites in partial and full veneers.1-4 in the direct–indirect technique, using similar shade selection and layering techniques that are used for the direct technique; the clinician applies a light-cured composite material to the tooth, with or without tooth preparation, without any adhesion. The composite is then shaped to a primary anatomic form with slight excess, and then light-cured. After that, the partially polymerized restoration is carefully removed (lifted) from the non-retentive, non-bonded tooth surface, heat-tempered extra-orally chairside, and finished and polished to final macro and micro anatomy. After shade try-in and confirmation of the overall fit and esthetics, the veneer is bonded to the preparation using a resin-based luting agent. Indirect laminate veneer restorations provide a valid conservative alternative to complete teeth coverage (full crown) as they avoid aggressive dental preparation; thus, maintaining tooth structure. Materials and methods: This is a retrospective study in which the case records of 380 patients were reviewed and details such as gender, age, type of materials used were collected. Details were tabulated in excel and results were obtained using SPSS. Chi square analysis was performed to find out the association between different variables. Results: Age range 16-25 years who received indirect veneering were at a higher rate (74.41%),age group 26-45 years (22.16%) and 46-70 years (22.06%) .Male population undergoes indirect veneering than the female population which is about 62.80%, 11 teeth number is the most common tooth undergone for indirect veneering which is about 27.97%. Conclusion: Within the limits of the present study, it can be concluded that A2 shade was the most common material used during indirect veneering with male predilection.
