Alveolar bone changes in the mandibular incisors after genioplasty, a three-dimensional study.

Introduction: Functional genioplasty aims to achieve lip competence at rest and reduces lip pressure against the mandibular incisors. The purpose of this study was to describe the radiographic changes in alveolar bone of the mandibular incisors after functional genioplasty.

Materials And Methods: Cone beam CT images from 36 patients were compared between immediate (T0) and delayed postoperative period (T1).

Alveolar bone changes after tooth-borne surgically assisted rapid maxillary expansion: A three-dimensional study.

Introduction: Surgically assisted rapid maxillary expansion (SARME) with a dental-anchorage appliance can induce dental and skeletal complications adjacent to the teeth supporting the device. The purpose of this study was to quantify the dentoskeletal changes observed after SARME using a tooth-borne device.

Materials And Methods: Cone beam CT images from 39 patients were compared between the preoperative (T1) and the postoperative period (T2).

Effect of 970 nm low-level laser therapy on orthodontic tooth movement during Class II intermaxillary elastics treatment: a RCT.

This prospective randomized clinical trial aimed to evaluate the effect of low-level laser therapy on tooth movement during Class II intermaxillary elastics treatment. Forty-two patients with Class II malocclusion were included, and their maxillary quadrants were allocated into two groups: treatment with an active diode laser and a placebo group. In each group, the time taken to obtain Class I occlusion after 6 months, rate of movement, total displacement of the maxillary canine to Class I occlusion and pain were recorded.

Variability of slot size in orthodontic brackets.

Objective: The accuracy of the information incorporated into brackets is a determining factor for the efficacy of torque applied to teeth. The aim of this study was to compare the dimensions of a bracket's slots with the nominal values announced by the manufacturer.

Materials And Methods: A total of 730 maxillary right central brackets manufactured by seven companies (Dentsply Gac, American Orthodontics, Rocky Mountain Orthodontics, GC Orthodontics, 3M Unitek, and Dentaurum) were studied.

Gingival biotype assessement: visual inspection relevance and maxillary versus mandibular comparison.

Objective: This clinical study was aimed at evaluating the accuracy of gingival visual inspection procedures during clinical examination and determining whether differences existed between the maxillary and mandibular gingival biotypes.

Materials And Methods: The study included 53 patients and 124 clinicians. The clinicians were asked to assign to each subject, using photographic documents, one of three biotypes: thin-scalloped, thick-scalloped, or thick-flat gingival biotype.

[Orthodontic tooth displacement: histology, biology and iatrogenic effects].

Iatrogenic effects of orthodontic forces, in particular root resorption, are described in the literature. However, our knowledge on the risk of osseous defects induced by orthodontic treatment is still scarce. After an overview of histological and biological principles of orthodontically-induced tooth movement, this study focuses on the recent data concerning the occurrence and the treatment of bone resorption associated with orthodontic treatment.
