Background And Objectives: Maxillary expansion is one of the most commonly advocated treatment approaches for the management of the maxillary deficiency in the transverse plane and is possible because of the presence of mid-palatal suture. This finite element method (FEM) study was taken to evaluate the stress pattern and displacement in the screw and its adjacent structures used in three different treatment modalities, such as rapid maxillary expansion (RME), mini-implant-assisted rapid palatal expansion (MARPE), and MARPE in conjunction with micro-osteoperforations.
Materials And Methods: An adult human dried skull, cone-beam computed tomography (CBCT) of the skull, and FEM and associated software (GEOMAGIC) were included.
Objective: A two-dimensional cephalometric study was carried out to assess the airway among individuals with Class I and Class II skeletal base.
Materials And Methods: Class II subjects were further categorized into horizontal and vertical growers and average growth patterns to check the possible relationship between the facial skeleton and pharyngeal airway. Lateral cephalograms of 150 subjects were obtained using standard protocol in natural head position (NHP).

Introduction: The relationship of the condyle and the mandibular fossa differs in shape with type of malocclusion and skeletal pattern. A review of literature shows till date there are no studies on Temporomandibular Joint (TMJ) condyle-fossa relation to the type of malocclusion based on growth pattern. Computed Tomography (CT) provides optimal imaging of the osseous components of the TMJ.

Aim: To identify features seen in molar distalization cases.
Aim: The aim of this study was to establish the validity of a new method for evaluating skeletal maturation by assessing the 3rd and 4th cervical vertebrae seen in the cephalometric radiograph.
Materials And Methods: This study consisted of a sample of 50 patients in the age group of 8 to 14 years of age. Chronologically, they were divided into six groups, based on the age consisting of a minimum of six to a maximum of 10 subjects.
