Abstract

Objective:

Miniscrews have become popular in recent years where absolute anchorage is desired. Besides many advantages offered by them, miniscrews still show lack of stability. One of the main factors for failure has been reported to be the (2018) optimal sites for the micro implant placement. This study was aimed to determine the interradicular distances in posterior maxillaryregion using cone bean computed tomography by mapping of the mesiodistal dimensions on the maxillary buccal site.


Materials & Methods:

A descriptive cross sectional study was conducted at the Orthodontic department Rehman College of Dentistry, Peshawar. 50 patients were evaluated using (CBCT apparatus (CS 9000) at 60 -90 kV). Linear Interardicular distances were measured from distal
of canine to the mesial of 1st molar at three levels (alveolar crest, mid root and the apex) using CS 3D imaging software.

Results:

Maxillary interradicular distances ranged from 1.00 mm to 6.20 mm. The distance tended to progressively increase from alveolar crest to apex and from canine to 1st molar. Greatest distance was found to be between 2nd premolar and 1st molar. Maximum distance was between 2nd premolar and 1st molar 3.60 mm, 5.10 mm, 6.20 mm at alveolar crest, mid root and apex level respectively. Minimum interradicular dimensions varied. At crest and mid root level it was found to be between canine and 1st premolar 1.20 mm and 1.00mm respectively. At the level of apex minimum distance measured was 1.20 mm between 1st premolar and 2nd premolar.

Conclusion:

Interradicular distance tended to increase from cervical line to apex and canine to 1st molar. Because of the greatest interradicular spaces between 2nd premolar and 1st molar, miniscrews of 1.2 to 1.6 mm diameter can safely be used.
