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

NCT06673576 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 12

Last updated 2024-11-05

No results posted yet for this study

Summary

The aim of this study is to assess the precision of the complete crown technique employed for the superimposition of 3D models, specifically in the quantitative volumetric evaluation of gingival tissues. This technique was initially introduced in an in-vitro study by Dritsas et al. (2023) as a means to achieve an accurate, reproducible, and simple method for quantification of gingival recession.

This study will involve the analysis of digital models in. ply format acquired through intraoral scanning of patients scheduled for esthetic crown lengthening, with predefined inclusion and exclusion

Conditions

  • Volume Assessment
  • Gummy Smile

Interventions

DIAGNOSTIC_TEST

Complete crown technique for superimposition

the complete crown technique, the crown of the tooth corresponding to the gingival margin under evaluation will be selected using the paint method and circular selection tool. The same selection process will be applied to the moving model.

DIAGNOSTIC_TEST

Gold standard technique for superimposition

the gold standard technique, adjacent intact teeth and a portion of the palatal gingiva will be selected. Superimpositions will be executed utilizing the software's iterative closest point algorithm (ICP).
