'Bone map' for a safe placement of miniscrews generated by computed tomography.

Abstract:

OBJECTIVES:The aim of this manuscript is to provide a bone map that can be used as a general guide to determine the areas where miniscrews can be safely anchored. MATERIALS AND METHODS:Twenty-one computed tomographies (CTs) of maxilla and mandible were taken by the imaging centre ORTOSCAN and two measures were taken: --first, the interradicular space in the mesiodistal plane of the maxillary and mandible teeth with slices taken at 3, 6, and 9 mm from the alveolar crest, in the palatine and vestibular slices, --second, the interradicular space in the vestibular-lingual direction. RESULTS:We can see that the greatest amount of mesiodistal bone is between the first and second inferior molars on the vestibular side and between the second and first inferior molars on the lingual side, whereas the least amount of bone on the mesiodistal plane is between the inferior incisors on the vestibular side. To determine the length of the miniscrew, we must take into account that the greatest amount of vestibular-lingual bone is between the first and second inferior molar, whereas the least amount is between the central and lateral inferior incisors. CONCLUSIONS:Mesiodistal values in vestibular are those that must be considered when inserting the microscrew so as not to damage the dental tissue. Mesiodistal measurements taken in palatal-lingual do not present problems when inserting microscrews.
