Clinical Performance of Fiber Reinforced FRC Base and Bonded CAD/CAM Resin Composite Endocrowns Versus Conventional Lithium Disilicate Endocrowns in Posterior Teeth (1y Randomized Clinical Trial).

Clinical Performance of Fiber Reinforced FRC Base and Bonded CAD/CAM Resin Composite Endocrowns Versus Conventional Lithium Disilicate Endocrowns in Posterior Teeth (1y Randomized Clinical Trial).

In patients with endodontically treated molar teeth indicated for endocrown, will the fiber reinforced FRC base and bonded CAD/CAM resin composite endocrowns restorations have a similar clinical performance to the conventional lithium disilicate endocrown over one year?

Inclusion Criteria:

• Patients with good oral hygiene
• Patients having one or more endodontically treated molars that need prosthetic restoration.
• Molars should have enough tooth structure for endocrown restoration with minimum 3 walls with thickness not less than 1.5 mm and gingival step placed supragingival
• Fully erupted molars
• Molars free of developmental defect
• Healthy periodontium
• Absence of periapical pathosis
• Acceptable endodontic treatment and proper bone support

Exclusion Criteria:

• Patients with bad oral hygiene
• Patients with active periodontal disease
• Patients with missing teeth opposing to the area intended for restoration
• Patients with parafunctional habits or psychiatric problems or unrealistic expectation.
