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

Phase 2

• Conditions: Personal Satisfaction
• Interventions: Other: Allceram; Other: hybrid crown

• Registration Number: NCT02929173

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.

Primary Outcome Measures

Name	Time	Method
Change in esthetic patient satisfaction	At crown delivery time and after delivery 3, 6, 9, 12 month	using Rating scores from 0-2 (0= Poor, 1=Accepted, 2=Excellent)

Secondary Outcome Measures

Name	Time	Method
Shade match to contralateral tooth	At crown delivery time and after delivery 3, 6, 9, 12 month	using Modified USPHS scores from 0-3 (0= Match to contralateral tooth, 1=Acceptable mismatch to contralateral tooth , 2=Unacceptable mismatch to contralateral tooth, 3=New restoration is needed.)
