Three-dimensional Evaluation of Interradicular Areas and Cortical Bone Thickness for Orthodontic Miniscrew Implant Placement Using Cone-beam Computed Tomography.

Background: Factors that influence anchorage of the orthodontic miniscrew implants are interradicular areas and cortical bone thickness.

Aims And Objectives: The aim of this study was to evaluate the three-dimensional interradicular areas and the buccal cortical bone thickness in Indian patients using cone beam computed tomography (CBCT) images, and to find the suitable and safe sites for orthodontic miniscrew implant placement.

Materials And Methods: CBCT images of 20 patients were divided into three planes as axial, coronal, and sagittal.

Comparison of the Anchorage Value of the First Molars Supported with Implant and First Molars Supported with Second Molar during En Masse Retraction.

Aims And Objectives: The aim of this study was to determine the efficacy of mini-implants as adjuncts for intraoral anchorage units for en masse retraction of maxillary anterior teeth in bimaxillary dentoalveolar protrusion cases.

Materials And Methods: The study sample consisted of 15 patients (10 females and 5 males). The samples were compared for anchorage loss with the implant-supported molar and conventional molar contralaterally in both the maxilla and mandible after six months of retraction period.
