ABSTRACT
Aims: The Objective Of This Study Was To Evaluate One-year Clinical Performance Of Composite Veneers Applied With Different Techniques.Methods And Material: This Study Was Conducted As A Modifiedrandomized Split-mouth Design On Site Level, Where The Two Groupes Composite Veneer Techniques Under Investigation Were Randomly Assigned To Either The Right Or Left Upper Anterior Teeth. The (group I) 16 Teeth Were Restored With A Prefabricated Composite Veneer System COMPONEER(COLTEEN), While (group II) 16 Teeth Were Restored With Free Hand Layering Direct Approach With IPS EMPRESS DIRECT (Ivoclar) Assisted With Preformed Template U-VENEER (Ultradent). At Baseline, 6 And 12 Months, The Restorations Were Evaluated Using ModifiedUSBHS Criteria For Marginal Discoloration, Recurrent Caries And Post Operative Hypersenstivity.Statistical Analysis Used: The Recorded Data At The Different Follow Up Periods Were Collected, Tabulated And Statistically Analyzed Using SPSS (Statistical Package For The Social Sciences) Software Version 25.0.

Results: Regarding The All Evaluation Criteria, Were No Statistically Significantlydifferent Between The Two Groups At The End Of Evaluation Period (p?0.05).

Conclusions: The Acceptable Clinical Performance Of Both Composite Veneer Techniques With Only Minor Changes Had Been Recorded Between Baseline And The Follow-up Evaluation At 12 Months.
