Comparing digital and conventional methods for dental impressions in implant-supported crowns
Investigating the Accuracy of Conventional vs Digital Impressions and Conventional vs 3D Fabricated Casts in Capturing the Emergence Profile Around Maxillary Anterior Single Implant-supported Crowns
This study tests whether digital or traditional methods for taking dental impressions work better for people getting implant-supported crowns in the front of their mouth.

What this trial studies
This study evaluates the accuracy of different impression techniques for capturing the peri-implant emergence profile of single implants in the maxillary anterior region. It compares conventional elastomeric impressions with direct and indirect digital scanning methods, as well as the effectiveness of 3D printed casts versus conventional epoxy-resin casts. The research focuses on patients with a thick gingival phenotype and aims to assess soft tissue collapse following provisional restoration removal. The findings could enhance the precision of dental restorations and improve patient outcomes.
Who should consider this trial
Good fit: Ideal candidates are adults over 18 with a single missing maxillary anterior tooth, a thick gingival phenotype, and good oral hygiene.
Not a fit: Patients with active periodontitis or peri-implant inflammation may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to more accurate dental impressions, resulting in better-fitting crowns and improved long-term outcomes for patients with dental implants.
How similar studies have performed: Other studies have shown promising results with digital impression techniques, indicating potential for success in this approach.
