Abstract
Aim: To measure the labio-lingual bone thickness in the mandibular interforaminal region to facilitate safe implant placement in patients of Indian origin.
Materials and Methods: Labio-lingual bone thickness was measured at 16 points in the interforaminal region of mandibles from 20 cadavers, in vitro, using Dial gauge tester.
Results: Mean thickness ranged from 9.23 to 11.80 mm with a minimal value of 5.542mm in the midline region. No significant difference was noted between dentate and edentulous specimens. This confirms that the loss of tooth has no influence on the basal process of the mandible.
Conclusion: The thinnest region is medially located and is narrower than the minimum required for a 3.75 mm diameter endosseous implant. Hence special attention is needed during surgical procedure to avoid lingual cortical breach and subsequent hemorrhage.
Keywords: Labio lingual bone thickness, mandibular implant safety.
