Unplanned tooth movement in deepbite correction with Invisalign: A retrospective study.

Background: This study aimed to investigate unplanned tooth movements in deepbite correction with Invisalign.

Methods: The sample consisted of 34 adult patients with deepbite malocclusion treated with Invisalign. Pretreatment and predicted digital models were exported from ClinCheck software, while the post-treatment model was obtained from an intraoral scan taken at the end of the first set of aligners.

Root resorption of maxillary incisors after en masse intrusion and retraction with controlled tipping versus bodily movement in adults.

Introduction: The purpose of this study was to evaluate and compare the incidence of orthodontically induced inflammatory root resorption (OIIRR) after en masse maxillary incisors intrusion and retraction with controlled tipping versus bodily movement using cone beam computed tomography (CBCT).

Material And Methods: This study is a retrospective study performed on CBCT scans of 36 adult females who had their maxillary first premolars extracted followed by en masse anterior retraction and intrusion using labial biocreative therapy type II. Subjects were divided into two groups of 18 subjects each based on the type of tooth movement required during en masse retraction: Group I; the controlled tipping group, and Group II; the bodily movement group.

Alveolar bone changes around maxillary incisors after intrusion and retraction with controlled tipping versus bodily movement : A retrospective cone-beam computed tomography study.

Objective: To compare the effect of maxillary incisor intrusion and retraction with controlled tipping (CT) versus bodily movement (BM) in extraction cases on alveolar bone height and thickness, using cone-beam computed tomography (CBCT). Correlations between changes in alveolar dimensions and crown or root retraction, incisor inclination, and intrusion were also investigated.

Materials And Methods: In all, 144 incisors of 36 women were retrospectively evaluated.

Type of tooth movement during retraction of the maxillary anterior teeth using labial versus lingual biocreative therapy in adults: A randomized clinical trial.

Objective: The objective of this two-arm parallel trial was to compare the type of tooth movement during retraction of the maxillary anterior teeth using labial versus lingual biocreative therapy.

Methods: Twenty-eight subjects were randomized in a 1 : 1 ratio to either the labial or lingual group. anterior retraction was performed using labial biocreative therapy in group A and lingual biocreative therapy in group B.

Three-dimensional mapping of cortical bone thickness in subjects with different vertical facial dimensions.

Background: The purpose of this study was to determine differences in cortical bone thickness among subjects with different vertical facial dimensions using cone beam computed tomography (CBCT).

Methods: From 114 pre-treatment CBCT scans, 48 scans were selected to be included in the study. CBCT-synthesized lateral cephalograms were used to categorize subjects into three groups based on their vertical skeletal pattern.

Alveolar bone mapping in subjects with different vertical facial dimensions.

Objective: The purpose of this study was to investigate differences in alveolar and skeletal dimensions among subjects with different vertical facial dimensions using cone beam computed tomography (CBCT). To date, this is the first study that investigates the relationship between facial type and posterior alveolar thickness in both maxilla and mandible, using CBCT data.

Materials And Methods: From a sample of 152 CBCT scans, 45 scans were selected to be included in the study.
