ABSTRACT

Objectives: Evaluation Of A Newly Performed Modification In Digital Volumetric Analysis Used To Assess Volume Changes After Soft Tissue Volume Augmentation Using Subepithelial Connective Tissue Graft In Localized Horizontal Ridge Defects Methodology: The Study Was Designed As A Single Armed Clinical Trial Including 13 Localized Horizontal Ridge Defects. Soft Tissue Volume Augmentation Using Subepithelial Connective Tissue Graft Was Performed In The Ridge Defects. Impressions Were Taken At Baseline, 10 Days, 1 Month, 2 Months And 3 Months Follow Up. The Casts Were Optically Scanned, Digitized And Transferred To Stereolithography (STL) Files. Casts Of Each Defect Were Superimposed, Trimmed Together, And The Volume Of The Defect Area Was Measured By The Software. Afterwards, Volume Gain Was Calculated At Each Follow Up Time Point. Descriptive Analysis Was Computed And Paired T Test For Normally Distributed Variables Was Used To Compare The Baseline And Last Follow Up.

Results: The Mean Volume Of The Defect Site Was 727.38 � 290.72 Mm?, And 783.46 � 298.48 Mm? At Baseline, And 3 Months Follow Up, Respectively With A Statistically Significant Volume Increase. The Final Volume Gain Between Baseline And 3 Months Follow Up Was 57.46 � 18.22 Mm? With A Statistically Significant Difference From The Initial Volume Gain.

Conclusions: The Modified Method Of Volumetric Analysis Is An Accurate Method For Assessing Soft Tissue Volume Augmentation That Is Easy To Standardize.
