Purpose: The purpose of this clinical evaluation was to assess the clinical effect of application of everStick Ortho glass fiber-reinforced composites for orthodontic lingual retainer.
Methods: A total of 12 patients underwent orthodontic treatment using glass fiber-reinforced composites for fixed orthodontic lingual retainers. During a 24-month follow-up period after application of retainers, the condition of lingual retainers and the periodontal status were examined every 6 months. Gingival index and sulcus bleeding index were analyzed by nonparametric tests with SPSS 13.0 software package.
Results: During 24-month follow-up period, 11 orthodontic lingual retainers were stable without fracture while the periodontal tissue revealed no significant changes in all 12 patients.
Conclusions: The application of everStick Ortho glass fiber-reinforced composites for orthodontic lingual retainer is a viable alternative to conventional retainer used in orthodontic treatment.

Aim: To evaluate risk indicators for gingival recessions (GRs) in the lower anterior teeth of orthodontic patients post treatment and during a retention period of at least 5 years, compared to non-treated controls.
Material And Methods: Eighty-nine orthodontically treated patients who were recession-free before treatment were recruited. Demographic, cephalometric and occlusal records were retrieved before (T1) and after treatment (T2), and periodontal outcomes were clinically evaluated at least 5 years post retention (T3).

The finite element method (FEM) is an advanced numerical technique that can be applied in orthodontics to study tooth movements, stresses, and deformations that occur during orthodontic treatment. It is also useful for simulating and visualizing the biomechanical behavior of teeth, tissues, and orthodontic appliances in various clinical scenarios. The objective of this research was to analyze the mechanical behavior of teeth, tissues, and orthodontic appliances in various clinical scenarios.

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.
Comprehensive review of polyetheretherketone use in dentistry.

Article Synopsis
- This study reviews the current applications, limitations, and challenges of using polyetheretherketone (PEEK) in stomatology, highlighting its importance in various dental procedures.
- Numerous studies underscore PEEK's beneficial properties, such as biocompatibility and fracture resistance, and its use in many dental applications, including implants and orthodontic devices.
- Despite its potential, most evidence is based on short-term studies, indicating a need for more long-term clinical research to fully support PEEK's effectiveness in dentistry.
Evaluation of microgaps and microleakage at the implant-abutment interface of individualized abutments in the maxillary anterior region under functional loading: A pragmatic clinical trial.

School and Hospital of Stomatology, Fujian Medical University, Fuzhou, China.
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.
