Deep Margin Elevation Vs Crown Lengthening

Biological Evaluation of Indirect Restorations in Endodontically-treated Posterior Teeth With Deeply Located Proximal Margins Following Deep Margin Elevation Versus Surgical Crown Lengthening: A Randomized Controlled Trial

The present clinical trial will be conducted to reject or accept the null hypothesis that in endodontically treated posterior teeth with deeply located proximal margins, will the Deep Margin Elevation will have better results from surgical crown lengthening in terms of biological criteria?

Inclusion Criteria:

• Patients underwent endodontic treatment in the posterior region
• 18-40 years
• Male and Females
• Medically free patients
• Patients with healthy periodontium
• Patients with thick biotype.
• Patients having proximal margins violating the biological width

Exclusion Criteria:

• Patients with chronic periodontal disease.
• Patients with persistent poor oral hygiene.
• Patients with unsuccessful root canal treatment.
• Periapical Abscess or Fistula.
• Patients with proximal margins beyond the bone level.
• Patients with developmental dental anomalies.
• Patients undergoing or will start orthodontic treatment
• Patients with removable prosthesis
