Brief summary
The aim of this study compare soft tissue reaction (bleeding, gingival color and texture), bacteria type and count in the gingival sulcus around the restoration margin and sulcus depth of Bio-compatible High performance polymer( Bio-Hpp) restorations to E-max regardless its 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:E.M. will record the crevice depth and bacterial count prior to preparation. E.M. will perform full coverage conservative tooth preparation following principles of all ceramic crown preparation with shoulder sub-gingival finish line of thickness 1mm using tapered stone with flat end attached to high speed headpiece with air and water coolant after local anesthesia has been given as required.After tooth preparation, E.M will take an adequate 2ry Impression using non aqueous Elastomeric impression materials Impregum™F( medium consistency,3M ESPE) and bite registration, Pink Soft wax(Star dental supply)will be taken. E.M will fabricate the temporary restoration using composite resin temporary material Protemp™4 Temporisation Material (3M ESPE) and cemented using non Eugenol Zinc Oxide temporary cement TempBond™ Temporization( Kerr Dental). E.M will deliver pressed Bio-compatible High performance polymer (Bio-HPP) frame work veneered with visio.lign system (Bredent) cemented by a self adhesive resin cement 2. Comparator: E.M. will record the crevice depth and bacterial count prior to preparation. E.M. will perform full coverage conservative tooth preparation following principles of all ceramic crown preparation with shoulder sub-gingival finish line of thickness 1mm using tapered stone with flat end attached to high speed headpiece with air and water coolant after local anesthesia has been given as required.After tooth preparation, E.M will take an adequate 2ry Impression using non aqueous Elastomeric impression materials Impregum™F( medium consistency,3M ESPE) and bite registration, Pink Soft wax(Star dental supply)will be taken. E.M will fabricate the temporary restoration using composite resin temporary material Protemp™4 Temporisation Material (3M ESPE) and cemented using non Eugenol Zinc Oxide temporary cement TempBond™ Temporization( Kerr Dental). E.M. will deliver Pres-sable E-max (IPS e.max®) framework will be veneered with e-max veneering system (Ivoclar Vivadent) .The finished crown will be cemented by Self-Adhesive resin Cemen taccording to manufacturer instructions. 3. Outcome:(i)Patient satisfaction (bio-compatibility) measure patient satisfaction using data in questionnaire (presence or absence of bleeding.) The main and standard deviation for the questionnaire of patient at the time crown cementation, 3, 6,9 and 12 months will be recorded. (ii) Clinical biological outcome: * measure the Crevice depth using periodontal probe and record the depth in millimeters collected a swap from the teeth and Bacterial count will be measured using culture number of cells per millimeter * The main and standard deviation for all collected data ,at the time of crown cementation, 3, 6,9 and 12 months will be recorded.
