Clinical Evaluation of Lithium Disilicate and Hybrid Nano-ceramic Anterior Endocrowns (Randomized Clinical Trial)

Clinical Evaluation of Lithium Disilicate and Hybrid Nano-ceramic Anterior Endocrowns (Randomized Clinical Trial)

the aim of this study was to evaluate the clinical performance of two CAD/CAM materials, hybrid nano-ceramic and lithium disilicate ceramic, in the fabrication of anterior endocrowns in patients with anterior endodontically treated teeth. While the postulated null hypothesis of this study was that there will be no significant difference between the performance of hybrid nanoceramic and lithium disilicate anterior endocrowns in patients with endodontically treated teeth.

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.
