Mandibular buccal shelf and infra zygomatic crest – A safe zone for miniscrew insertion

Abstract

Miniscrew has brought evolution in the world of orthodontics by providing skeletal anchorage which helps to convert surgical case into non-surgical case. Various sites (commonly interradicular region) are present for miniscrew insertion. Commonest disadvantage is loosening of implant during course of treatment. Thickness of cortical bone which is a variable factor is important for bone screw stability. Mandibular buccal shelf region and infra zygomatic crest region provide adequate cortical bone thickness and are apt site for bone screw placement. The aim of the study was to analyze Mandibular buccal shelf region and infra zygomatic region and provide anatomical map to clinician for bone screw placement.
