What this trial studies
This clinical trial aims to compare the effectiveness of guided digital planning against conventional analog planning for crown lengthening procedures in patients with excessive gingival exposure, commonly referred to as a gummy smile. A total of 44 participants will be randomly assigned to either the digital methodology group or the analog methodology group. The digital approach involves creating a digital scan and using computed tomography to develop a surgical guide, while the analog method relies on traditional impressions and radiographs. Measurements will be taken at various intervals to assess outcomes and patient experiences.
Who should consider this trial
Good fit: Ideal candidates for this study are adults over 18 with specific dental conditions related to excessive gingival exposure and no significant attachment loss in the treatment area.
Not a fit: Patients who smoke, are pregnant or lactating, or have systemic conditions affecting gingival presentation may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance the precision of crown lengthening procedures, leading to improved aesthetic outcomes for patients with gummy smiles.
How similar studies have performed: Previous studies have shown promising results with digital planning techniques in dental procedures, suggesting potential for success in this approach.
