  • Title: Perioperative validation of localisation of the mental foramen.
    Author: Bou Serhal C, Jacobs R, Flygare L, Quirynen M, van Steenberghe D.
    Journal: Dentomaxillofac Radiol; 2002 Jan; 31(1):39-43. PubMed ID: 11803387.
    Abstract:
    AIM: To assess the accuracy of panoramic radiography and spiral or computed tomography for the localisation of the mental foramen. MATERIALS AND METHODS: The distance from the alveolar crest to the mental foramen was measured from panoramic radiographs, spiral tomograms and CT scans. The same distance was measured during implant surgery using a specially designed caliper. RESULTS: Panoramic radiography showed more deviation (+0.6 mm) from the perioperative measurements than either spiral or computed tomography (+0.4 and -0.3 mm respectively). The difference was significant (P<0.05). In general, distances were overestimated on the panoramic radiographs. CONCLUSIONS: Cross-sectional imaging techniques are recommended for the pre-operative planning of implants in the posterior mandible.
