Purpose: Aim of the present study was to investigate the prevalence of gingival recession and related factors in teeth with low occlusal function (open bite and infraversion) after orthodontic treatment.
Methods: From January 2014 to December 2017, 403 patients received orthodontic treatment. Their gingival recession and related factors before and after treatment were retrospectively analyzed.
Results: The prevalence of gingival recession in patients with infraversion and open bite after orthodontic treatment were 80.6 and 75.0%, respectively; these values were 43.4 and 47.5% before treatment, respectively. Notably, the Miller index of gingival recession increased after orthodontic treatment (P < 0.05). The risk of gingival recession in patients with infraversion or open bite after orthodontic treatment was remarkably higher than the risk in other patients (odds ratio [OR] = 16.712 and 5.073, respectively); the gingival recession rate was related to treatment with tooth extraction (OR = 2.043), as well as gingival biotype (OR = 0.341) and gingival index (GI) before orthodontic treatment (OR = 97.404; P < 0.05).
Conclusions: Patients with these two types of low occlusal function are more likely to exhibit gingival recession after orthodontic treatment. Moreover, the prevalence of gingival recession after orthodontic treatment is higher among patients who have undergone tooth extraction during orthodontic treatment, and among those who exhibit thin gingival biotype and high gingival index before orthodontic treatment.

Background: Gingival recession defects (GRDs) pose functional and esthetic concerns and may be associated with unfavorable tooth positions. Surgically facilitated orthodontic treatment (SFOT) with clear aligners can be a valuable option for adults with severe malocclusion and GRDs.
Methods: A 28-year-old male presented with severe dental crowding, Class III dental malocclusion, localized tooth crossbites, and tapered maxillary arch.

Aim: To evaluate risk indicators for gingival recessions (GRs) in the lower anterior teeth of orthodontic patients post treatment and during a retention period of at least 5 years, compared to non-treated controls.
Material And Methods: Eighty-nine orthodontically treated patients who were recession-free before treatment were recruited. Demographic, cephalometric and occlusal records were retrieved before (T1) and after treatment (T2), and periodontal outcomes were clinically evaluated at least 5 years post retention (T3).

Objectives: To identify landmarks in ultrasound periodontal images and automate the image-based measurements of gingival recession (iGR), gingival height (iGH), and alveolar bone level (iABL) using machine learning.
Methods: We imaged 184 teeth from 29 human subjects. The dataset included 1580 frames for training and validating the U-Net CNN machine learning model, and 250 frames from new teeth that were not used in training for testing the generalization performance.
The integrity and phenotype of periodontal soft tissues significantly influence the outcome of surgical periodontal regenerative therapy. In cases with thin gingival phenotype, treating infrabony defects surgically can worsen gingival recession and loss of papillae. This report outlines a surgical approach for addressing infrabony defects at sites with gingival recession and thin phenotype.

Materials And Methods: The study includes patients who were treated at a dental clinic in Italy from 2012 to 2022. These patients received fixed screw-retained complete dentures supported by either two or four zygomatic implants (ZIs).
