Effect of Different Types of Crowns on Patient Satisfaction and Clinical Assesment

Patient Satisfaction and Clinical Assessment of Biocompatible High Performance Polymers Crown Veneered With Visio.Lign Versus E-max Crown Veneered With E-max Veneering System in Anterior Aesthetic Zone.(Randomized Controlled Clinical Trial)

• Status: Unknown
• Phase: Phase 2
• Study type: Interventional
• Enrollment: 24 (estimated)
• Sponsor: Cairo University · Academic / Other

Summary

The aim of this study is to compare the patient satisfaction and clinical assessment (shade matching, surface texture and marginal discoloration) of Bio- High Performance Polymers (HPP) restoration versus E-max restoration compared to contralateral tooth in anterior zone. Regardless E-max popularity in the dental field.

Evidence Based Dentistry Committee (CEBD) Help in reporting study protocol following SPIRIT guidelines; Faculty of Oral and Dental Medicine, Cairo University, Egypt. 7.Research Ethics Committee (CREC): Protocol reviewer of the clinical trial in order to protect the right, safety, dignity and well-being of the participants; Faculty of Oral and Dental Medicine, Cairo University, Egypt. 8\. Research Plan Committee (CRPC):For ensuring that this clinical trial following the department research plan; Fixed prosthodontic Department, Faculty of Oral and Dental Medicine, Cairo University, Egypt. 1. Intervention: N.H. will perform conservative tooth preparation following the principles of all ceramic crown preparation with shoulder subgingival finish line of thickness 1.2mm using tapered stone with flat end attached to high speed headpiece with air and water coolant, after local anesthesia has been given. N.H. will take adequate 2ry Impression using non aqueous Elastomeric impression materials Impregum™F (medium consistency, 3M ESPE ,) and bite registration will by pink soft wax (Stardentalsupply) . N.A. \& E.O. will visually select the shade match using Vita Easyshade Compact (Vita Zahnfabrik, Bad Sa¨ckingen,Germany). N.H will fabricate the temporary restoration using Protemp™ 4 Temporisation Material(3M ESPE ) and cemented using non Eugenol Zinc Oxide temporary cement TempBond™ Temporization (Kerrdentalsupply). N.H will deliver Press Bio - HPP framework material veneered with visio lign veneering material (Bredent) crown and cement it with 3M™ ESPE™ RelyX™ Unicem Self-Adhesive Universal Resin Cement. 2. Comparator N.H. will perform conservative tooth preparation following the principles of all ceramic crown preparation with shoulder subgingival finish line of thickness 1.2mm using tapered stone with flat end attached to high speed headpiece with air and water coolant, after local anesthesia has been given. N.H. will take adequate 2ry Impression using non aqueous Elastomeric impression materials Impregum™F (medium consistency, 3M ESPE ,) and bite registration will by pink soft wax (Stardentalsupply) . N.A. \& E.O. will visually select the shade match using Vita Easyshade Compact (Vita Zahnfabrik, Bad Sa¨ckingen,Germany). N.H will fabricate the temporary restoration using Protemp™ 4 Temporisation Material(3M ESPE ) and cemented using non Eugenol Zinc Oxide temporary cement TempBond™ Temporization (Kerrdentalsupply). N.H will deliver E.max® framework veneered with E-max veneering System (Ivoclar Vivadent) crown and cement it with 3M™ ESPE™ RelyX™ Unicem Self-Adhesive Universal Resin Cement. 3. Outcomes A. Primary outcome: Patient satisfaction: E.O will measure patient satisfaction using Rating scores. The mean and standard deviation for the Rating scores of the patients will be recorded at the time of crown cementation, 3, 6, 9 \& 12 months after review for aesthetics. B. Secondary outcome: Clinical assessment of the restoration: E.O will evaluate shade matching, marginal discoloration and surface texture using modified USPHS criteria scores. The mean and standard deviation for the USPHS criteria scores of the patients will be recorded at the time of crown cementation 0, 3, 6, 9 \& 12 months after review for aesthetics.
