The increase in demand for adult orthodontics has been mirrored by an increased availability and demand of cosmetic appliances. This article focuses on one type of cosmetic appliance--the lingual appliance. Factors to consider in case selection as well as the advantages and disadvantages of lingual appliances are discussed. This paper also outlines the sequence of treatment using these appliances by way of two treated cases.

Background: Proper torque control is crucial to the outcome of orthodontic treatment. This study aimed to employ finite element analysis to compare the torque capabilities of a novel spherical self-ligating bracket with a lock-hook system against those of commonly used passive self-ligating and conventional bracket systems, as well as to reveal the biomechanical changes in the periodontal ligament (PDL) during torque expression.
Methods: A maxillary right central incisor, along with its PDL and alveolar bone, were modeled.

Purpose: This study aimed to evaluate the effect of functional loading on microgaps and microleakage at implant-abutment interfaces (IAIs) in the aesthetic zone when using different abutments and to provide a clinical reference for abutment selection.
Methods: This study included 30 patients with 36 implants divided into three groups: zirconia (Zr)-one-piece custom abutment, titanium (Ti)-custom abutment, and Ti-original abutment. Scanning electron microscopy was used to examine alterations in the microgaps at the IAIs under functional loading.

Introduction: The dentoskeletal effects of clear aligner treatment (CAT) with Invisalign vs temporary skeletal anchorage device-anchored Sydney intrusion spring (SIS) were compared in consecutively treated growing patients with anterior open bite using cone-beam computed tomography scans.
Methods: Fifteen adolescents treated exclusively with Invisalign, and 14 with SIS (first-phase treatment) were assessed retrospectively. Rigid-wise, voxel-based registration of pretreatment and posttreatment cone-beam computed tomography scans were performed using the anterior cranial base, maxillary plane, and mandibular body as reference regions.

The primary objective was to systematically assess the prevalence, incidence and risk factors of WSLs with orthodontic treatment. The secondary objective was to compare the prevalence of WSLs between conventional fixed appliances (CFA) and other appliances, as well as with no treatment. PubMed, Scopus, Web of Science, LILACs, Virtual Health Library and Cochrane CENTRAL were searched.
