Introduction: An anterior open bite is a form of vertical discrepancy that presents as a lack of contact between maxillary and mandibular segments. The treatment modalities usually involve either intrusion of posterior teeth or extrusion of anterior or a combination of both. The anatomical relationship between the apex of the maxillary molar roots to the inferior wall of the maxillary sinus floor is crucial in planning posterior intrusion.

Background Microleakage under orthodontic brackets has a role in early bracket debonding and white spot lesions due to the ingress of oral fluids in the bracket-adhesive-tooth interface. This in vitro study aimed to evaluate and compare the microleakage under orthodontic brackets bonded with the conventional adhesive system, nanocomposites, and nanoionomers. Materials and methods Forty-five human premolars were extracted for therapeutic reasons and collected for this study.

The Rationale: The surgery-first approach (SFA) has revolutionized orthognathic surgery in recent years and in trend because it addresses the dentofacial abnormalities first, making the patient compliant and outcome more predictable.

Patient Concerns: A 22-year-old female was concerned about her forwardly placed teeth.

Diagnosis: She had a compromised periodontium with a skeletal Class II malocclusion and dental malocclusion.

Skeletal Class II malocclusions with vertical maxillary excess (VME) present with an amalgamation of several problems pertaining to psychological, esthetics, and function. The optimal treatment plan in such cases includes a synchronized orthodontic-surgical approach through superior repositioning and setback of maxilla by means of Le Fort I osteotomy and augmentation genioplasty. This case report describes a multidisciplinary approach in the successful management of a patient with VME to achieve superior esthetics and function.

Introduction: To analyse the importance of bodily characteristics of growing children and its correlation towards skeletal maturity. This further aids orthodontists in proper treatment planning.

Aim: The purpose of this study was to assess the correlation between cervical vertebrae maturation, statural height and body weight as measured in 12 -year-old children.

Introduction: One of the major limiting factors in retraction of proclined teeth is the width of the alveolus both in maxilla and mandible.

Aim: The objective of this study was to assess the maxillary and mandibular anterior alveolar dimensions and to correlate with mandibular divergence in Class I bi-dento-alveolar protrusion patients.

Materials And Methods: Pretreatment lateral cephalograms (n=88) were analysed using a composite analysis with cephalometric software.

Introduction: During tooth movement the success of sliding mechanics is dependent upon various factors which include frictional resistance at bracket-archwire interface, surface roughness of archwire materials and elastic properties of archwires. Ion implantation techniques reduce the frictional force and allow better tooth movement clinically.

Aim: The main objective of this study was to evaluate and compare the frictional properties, load deflection rate and surface characteristics of Honey dew and Purple coloured (Ion implanted) TMA wires with uncoated TMA wires.
