Assessing a new technique for measuring gum tissue changes in aesthetic dentistry

Assessment of The Accuracy of Complete Crown 3D Superimposition Technique Relative to The Gold Standard Technique for Digital Quantification of Volumetric Soft Tissue Changes in The Esthetic Zone

Not applicable Interventional British University In Egypt · NCT06673576

What this trial studies

This study evaluates the accuracy of a complete crown technique for superimposing 3D models to quantitatively assess changes in gingival tissues during aesthetic crown lengthening procedures. Patients will undergo presurgical and follow-up intraoral scans, with digital models analyzed for volumetric changes over a six-month period. The study aims to compare this new technique against a gold standard method to determine its precision and reliability in clinical settings.

Who should consider this trial

Good fit: Ideal candidates are patients requiring aesthetic crown lengthening with sufficient keratinized tissue and good oral hygiene.

Not a fit: Patients with systemic health conditions affecting healing, those requiring prosthetic crowns in the aesthetic zone, or those with a gummy smile and normal tooth proportions may not benefit from this study.

Why it matters

Potential benefit: If successful, this technique could provide a more accurate and reproducible method for assessing gum tissue changes, improving outcomes in aesthetic dental procedures.

How similar studies have performed: While this approach is based on a novel technique introduced in a previous in-vitro study, its clinical application remains largely untested.
