Evaluation of Two Mini-implant Lengths in the Infrazygomatic Crest Region: A Randomized Clinical Trial.

Objective:   Temporary anchorage devices (TADs) have revolutionized fixed orthodontic appliance treatment through anchorage controlling in the clinic and play an essential role in resolving many complex cases. Due to the limited space, there is a risk of injury to the roots while using interradicular microimplants. Therefore, the infrazygomatic crest (IZC) area can be an alternative mini-implant insertion site in the maxillary arch.

Is occlusal contact re-established within 6 months after bonding of a fixed anterior bite plane in adolescents with a Class II division 2 incisor relationship? A randomised controlled trial.

Objective: To determine if re-establishment of occlusal contact was achieved within 6 months after insertion of a fixed anterior bite plane in individuals with Class II division 2 incisor relationship, and to evaluate the occlusal and vertical skeletal changes and acceptance of the intra-oral scanner and bite plane.

Design: Single-centre two-arm parallel group randomised controlled trial with 1:1 allocation to intervention and control groups.

Setting: Dundee Dental Hospital and Research School, UK.

Helping general dental practitioners use the Index of Orthodontic Treatment Need: an assessment of available educational apps.

Introduction The Index of Orthodontic Treatment Need (IOTN) defines who receives treatment on the NHS. The British Orthodontic Society developed the 'Easy IOTN' app to help the dental team use IOTN more effectively.Aim This study aims to investigate the quality of the 'Easy IOTN' app and any alternative mobile apps developed to aid a dentist's ability to use IOTN.

Extraction vs nonextraction orthodontic treatment: a systematic review and meta-analysis.

Objectives: To compare four first premolar extraction and nonextraction treatment effects on intra-arch width, profile, treatment duration, occlusal outcomes, smile aesthetics and stability.

Materials And Methods: An electronic search of the literature to June 2, 2023 was conducted using health science databases, with additional search of gray literature, unpublished material, and hand searching, for studies reporting nonsurgical patients with fixed appliances regarding sixteen sub-outcomes. Data extraction used customized forms, quality assessed with ROBINS-I (Risk Of Bias In Non-randomized Studies-of Interventions) and Cochrane RoB 2 (risk-of-bias) tool.

Failure rates and factors associated with infrazygomatic crestal orthodontic implants - A prospective study.

Objective: Infrazygomatic crestal (IZC) implants have gained increased popularity over the past few years. Hardly any studies have been done to assess the rate and reasons for failure of IZCs. This prospective study was planned and designed with the primary objective of assessing the rate of failure of bone-screws (BS) placed in the infrazygomatic crest.

Cephalometric Analysis in Orthodontics Using Artificial Intelligence-A Comprehensive Review.

Artificial intelligence (AI) is a branch of science concerned with developing programs and computers that can gather data, reason about it, and then translate it into intelligent actions. AI is a broad area that includes reasoning, typical linguistic dispensation, machine learning, and planning. In the area of medicine and dentistry, machine learning is currently the most widely used AI application.

A 3D cephalometric protocol for the accurate quantification of the craniofacial symmetry and facial growth.

Background: Cephalometric analysis is used to evaluate facial growth, to study the anatomical relationships within the face. Cephalometric assessment is based on 2D radiographic images, either the sagittal or coronal planes and is an inherently inaccurate methodology. The wide availability of 3D imaging techniques, such as computed tomography and magnetic resonance imaging make routine 3D analysis of facial morphology feasible.

Stress distribution patterns at mini-implant site during retraction and intrusion--a three-dimensional finite element study.

Background: The purpose of this study was to evaluate the stress patterns produced in mini-implant and alveolar bone, for various implant dimensions, under different directions of simulated orthodontic force, using a three-dimensional finite element method.

Methods: Eight finite element (FE) models of mini-implant and bone were generated with insertion angles of 30° and 60°, diameters of 1 and 1.3 mm, and lengths of 6 and 8 mm.

Current Applications and Future Prospects of Stem Cells in Dentistry.

Stem cells are defined as clonogenic, unspecialized cells capable of both selt-renewal and multi-lineage differentiation, contributing to regenerating specific tissues. For years, restorative treatments have exploited the lifelong regenerative potential of dental pulp stem cells to give rise to tertiary dentine, which is therapeutically employed for direct and indirect pulp capping. Current applications of stem cells in endodontic research have revealed their potential to continue root development in necrotic immature teeth and transplanted/replanted teeth.
