“…Thus, a minimum of 3.2 mm of inter radicular bone is required for placement of the mini-implant for orthodontic anchorage. 11 The insertion site for placement of the mini-implant depends on implant biomechanics as well as the patient's oral anatomy like the location of maxillary sinus and course of mandibular nerve. 12,13 Mental foramen lies between 1 st and 2 nd mandibular premolar.…”

To measure the inter-radicular spaces in both arches for miniscrew implant placement and to determine the most reliable sites using CBCT. A CBCT radiograph was taken for 75 subjects that met with inclusion criteria. They were divided into 3 categories- Hypodivergent, average, and hyperdivergent group. Images were calibrated by using software and printed as a film. Interradicular space on the right side of the jaw was measured in the sagittal plane after assuming the jaw to be symmetrical. Bucco-lingual and mesiodistal width were measured up to desired bone levels. In vertical growth pattern, in posterior maxilla highest mesiodistal width between 2nd premolar and 1st molar at 7mm. In the mandible, it was between the 1st and 2nd molar at 11mm. In horizontal growth pattern, in posterior maxilla highest mesiodistal width between 1st and 2nd premolar, and mandible it was between 1st and 2nd molar at 11mm. In average growth pattern, in posterior maxilla highest mesiodistal width between 2nd premolar and 1st molar and 1st molar at 7mm. In the mandible, it was between the 1st and 2nd molar at 11mm. The importance of the relationship between the growth pattern and the availability of inter radicular space may aid the clinician in planning appropriate surgical sites for miniscrew implant placement.
