Factors associated with complete recession coverage (CRC) were also analyzed. Methods Electronic health records from an academic institution were reviewed. Cases included three or more adjacent teeth with RT1 or RT2 recessions treated with CTG or ADM using the double‐VISTA technique and ≥12 months of follow‐up. The primary outcome was CRC. Secondary outcomes included recession depth (RD) reduction, percentage of RD reduction, keratinized tissue width (KTW) gain, Class I buccal furcation coverage, and Modified Root Coverage Esthetic Score (MRCES). Multivariate generalized estimating equations identified predictors of CRC. Results A total of 226 teeth from 36 patients met inclusion criteria. CRC was significantly higher with CTG than ADM (80.0% vs. 48.8%, &lt;jats:italic&gt;p&lt;/jats:italic&gt; &lt; 0.001). CTG demonstrated greater RD reduction (2.57 ± 1.01 mm vs. 2.33 ± 0.77 mm, &lt;jats:italic&gt;p&lt;/jats:italic&gt; = 0.019), percentage of RD reduction (89.9% vs. 80.6%, &lt;jats:italic&gt;p&lt;/jats:italic&gt; &lt; 0.001), KTW gain (0.39 ± 0.54 mm vs. 0.14 ± 0.35 mm, &lt;jats:italic&gt;p&lt;/jats:italic&gt; &lt; 0.001), and MRCES. Class I buccal furcation coverage was more frequent with CTG than ADM (53.8% vs. 9.1%, &lt;jats:italic&gt;p&lt;/jats:italic&gt; = 0.028). RT1 defects, absence of Class I furcation involvement, thick gingival phenotype, and CTG as grafting material, were associated with CRC. Conclusion CTG provided more favorable CRC, RD reduction, KTW gain, MRCES, and Class I furcation coverage compared with ADM. CRC was strongly associated with baseline recession type, furcation involvement status, gingival phenotype, and grafting material used. Plain language summary This study looked at two commonly used soft tissue grafting materials for treating gum recession affecting multiple teeth, especially when teeth also had surface structure loss not caused by decay. The two materials compared were connective tissue graft (taken from the patient's hard palate) and a donated human‐derived tissue product. Both were used together with a surgical method called the double‐vestibular incision subperiosteal tunnel access (double‐VISTA) technique. Researchers reviewed dental records from a university clinic and analyzed outcomes from 226 teeth in 36 patients who were followed for at least 1 year. The main goal was to evaluate how often complete root coverage was achieved. Other outcomes included how much the gum recession improved, changes in gum thickness, and whether gum tissue successfully covered mild furcation defects in molars. Overall, connective tissue grafts showed better results than human‐derived tissues.

The lower anterior region is particularly susceptible, yet the anatomical and clinical factors contributing to this vulnerability are not fully defined using digital tools. In this cross-sectional study of 103 patients (618 teeth), we integrated clinical examination, digital intraoral scanning, and CBCT to quantify soft and hard tissue characteristics. Recession was present in 70.9% of patients and 38.3% of teeth, predominantly affecting the central incisors.

Implants were categorized into favorable, questionable, unfavorable, and hopeless, based upon the prognosis categories proposed by Kwok et al. in 2023.
