Treatment of a Gingival Recession With In-Office Orthodontic Aligners and Gingival Graft.

Objective: Gingival recession is a complication that can occur after orthodontic treatment, and its cause is still very controversial in the literature. The objective of this study was to report a clinical case of orthodontic retreatment conducted with in-office aligners and root coverage using free gingival graft, connective tissue graft, and Emdogaim for a patient with severe gingival recession.

Clinical Considerations: This report presents a potential solution to correct a gingival recession with in-office clear aligner.

Comparison of the efficiency of initial dental alignment with Invisalign® aligners changed every 7 or 14 days in mature adults: Randomized clinical trial.

Objective: To compare the anterior crowding correction after sequential use of the first 5 aligners between two aligner exchange protocols (7 and 14 days) in mature adult patients.

Materials And Methods: Thirty-six patients over 35 years who received orthodontic treatment with Invisalign® were randomly allocated to two different aligner replacement sequence protocols: Group 1: exchange every 7 days (n = 18); and Group 2: exchange every 14 days (n = 18). All patients were scanned with iTero Element 5D® (Align Technology) in two treatment times: at pre-treatment (T1) and after using the first five aligners (T2).

The effect of hard tissue surgical changes on soft tissue displacement: a pilot CBCT study.

Introduction: This pilot study had as main objective to test the reliability of a new method to evaluate orthognathic surgery outcomes and also, to understand the effect of hard tissue changes on soft tissue displacement.

Methods: The sample consisted of eight patients that underwent bimaxillary advancement and had CBCT at two time points (before surgery and 6-8 months follow-up). Voxel-based cranial base superimposition was used to register the scans.
