Protraction of mandibular posterior teeth into edentulous regions is challenging in clinical practice. This case demonstrated a minor tooth movement of a mandibular second molar to substitute its adjacent missing first molar in a 15-year-old female. An efficient bodily movement of the mandibular second molar was achieved through a mini-implant-anchored protraction loop appliance. With this carefully designed biomechanical system, over 10-mm molar protraction was accomplished within 14 months without mesial or lingual tipping...

INTRODUCTION: Maxillary anterior teeth that have not erupted may substantially alter the appearance of the teeth and face. Orthodontists often encounter a clinical challenge while dealing with an impacted maxillary incisor, which creates space problems in the anterior region. The purpose of this paper is to describe the well-synchronized orthodontic and surgical treatment of a horizontally impacted maxillary central incisors. CASE PRESENTATION: A male patient, aged 27, presented with a complaint of unerupted two maxillary front teeth...

Excessive orthodontic force can induce inflammatory tooth root resorption due to sustained high stresses within the periodontal ligament (PDL). This study aimed to analyze the PDL pressures during upper incisor retraction using the en masse method with TISAD. The finite element method (FEM) ensured consistent conditions across cases. The models included bone geometry, adjacent teeth, PDL, and orthodontic hardware, analyzed with LS-Dyna. The pressure ranged from 0.37 to 2.5 kPa across the dental arch, with the central incisors bearing 55% of the load...

Polishing after the removal of brackets is the final step in orthodontic treatment. It is simple to perform, though some studies have reported that polishing causes damage to the enamel surface. An in vitro study was made of the influence of the buccal surface convexity of the tooth upon possible enamel loss when the remaining resin and adhesive are removed after bracket decementing using two different polishing modes: a tungsten carbide bur at low and high speeds. The convexity of the buccal surface was quantified in 30 incisors and 30 premolars...

The experimental group received orthodontic brackets coated with nanoparticles, while the control group received regular brackets...

BACKGROUND: Acid etching enamel improves resin-enamel adhesion and adhesive characteristics, but has pros and cons. The effects of laser etching on the bonding of orthodontic brackets vary depending on the wavelength, power output, exposure duration, and energy delivered. MATERIALS AND METHODS: This study used a new 1064-nm diode laser to irradiate 30 freshly extracted human premolars. They were divided into three groups: group A, group B, and group C. Acid etching was used for 1 min to bond bracket to tooth surface, and Indian ink was used for 30 s...

INTRODUCTION: Numerous manufacturers have improved bracket retention systems as a result of the frequent bond failure that occurs during orthodontic treatment. One of the elements affecting the adhesive's bond strength is the bracket retention mechanism. OBJECTIVES: This study's objective was to assess how various bracket base retention characters affected shear bond strength. MATERIALS AND METHODS: Four distinct base features for brackets were evaluated...

INTRODUCTION: The esthetic during the various orthodontic treatments has led to the invention of the brackets. When different ceramic brackets and archwires are used, the different frictional forces may result in the different outputs. Hence, in the present study, we evaluated and compared the frictional resistance between eight standard monocrystalline ceramic bracket models and each of the archwires of four different alloys. MATERIALS AND METHODS: Frictional force was tested using Instron testing machine, in vitro , for eight types of monocrystalline ceramic bracket, and four types of archwires beta-titanium, NiTi, copper-nickel-titanium, and stainless steel statistical analysis were done using various tools, and significance value of <0...

BACKGROUND: The use of lasers in orthodontics has garnered interest for its potential to enhance the bond strength between orthodontic brackets and tooth surfaces, a crucial factor for successful orthodontic treatment. This study aims to investigate the effect of laser irradiation on the bond strength of orthodontic brackets in a sample of 30 patients. MATERIALS AND METHODS: Thirty patients undergoing orthodontic treatment were divided into two groups. In Group A, brackets were bonded using conventional methods, while in Group B, brackets were bonded after laser irradiation...

OBJECTIVES: To assess a bracket-bonding system's shear bond strength cured with dissimilar light-curing units at different time intervals. MATERIALS AND METHOD: Sixty premolar teeth removed for orthodontic purposes were categorized into four types based on the light-curing unit and exposure times used. The specimens in the halogen group were exposed to light for 15 (Group I) and 30 (Group II) sec, respectively. The specimens were exposed to light for 10 (Group III) and 15 sec in the LED group (Group IV)...

BACKGROUND: The aim of this study was to evaluate the effect of separately curing the unfilled resin for increased bond strength of the orthodontic brackets as the literature shows both studies that support and contradict this aspect. METHODOLOGY: The sample consisted of 120 specimens randomly grouped into four of 30. The tooth was cleaned of tissue and debris and stored in a distilled water solution until the procedures of bonding. The surface of the enamel was conditioned with pumice, and acrylic blocks were designed for the tooth to be mounted onto them...

This study aims to examine the play between various archwires and bracket systems, exploring potential variations in angle values for specific torque and torque values for a given angle along different bracket systems. Therefore, seven brackets systems were evaluated in conjunction with different stainless steel archwires of varying dimensions (0.016″ × 0.022″, 0.018″ × 0.025″, and 0.019″ × 0.025″). Biomechanical behavior during torque development and transmission was assessed using a six-component force/torque sensor...

Orthodontic treatment during adolescence can contribute to the development of problematic eating disorders. This case study presents the situation of a 12-year-old male patient who experienced a prolonged period of dietary limitation, showed signs of chronic illness, and underwent a significant weight loss because of wearing dental braces. These circumstances triggered the emergence of atypical eating behaviors and complicated the therapeutic process. A case report highlights the effectiveness of conducting psychological evaluations for patients with braces who experience significant weight loss to address possible eating disorders...

OBJECTIVE: This study aimed to assess the frequency with which orthodontic patients decided to shift to another type of orthodontic appliance, among conventional metal brackets, ceramic brackets, lingual brackets and clear aligner, based on their personal experiences of pain, ulcers, bad breath, hygiene issues and social difficulties. MATERIAL AND METHODS: This study comprises of patients seeking orthodontic treatment. The sample (n = 500; age group = 19-25 years) was divided equally into four groups based on the treatment modality: conventional metal brackets, ceramic brackets, lingual brackets and clear aligner...

BACKGROUND: The physical appearance of an individual plays a primary role as it influences the opinion of the viewer. For this reason, orthodontic therapy to improve perceived aesthetics is in high demand among patients. This factor, combined with the increase in the number of non-invasive facial aesthetic treatments, has led to the need to understand potential risk factors in the application of medical devices to the perioral skin in patients with fixed orthodontic appliances. The aim of this study was to evaluate in vitro heating of the orthodontic bracket following electromagnetic fields and negative pressure (V-EMF) used as an anti-aging treatment...
