Anatomical study about anterior mandibular lingual foramina

"Introduction: In descriptions of surgical procedures in. the inferior jaw, often there is no mention of an. important anatomical variance, the spinal lingual. foramina, where nerves and vessels go through. Aim. of this study is to investigate the frequency, the shape. and the dimension of anterior mandibular lingual. foramina and their canals, in order to give more. information to operators who have to consider these. structures in a correct planning of the surgical. procedures. Materials and methods: 25 computed. tomography dentascans were analyzed with an implant. planning software (MICERIUM IMPLANT PLANNINGM.I.P.).. The parameters considered were the. frequency, the number, the localization, the diameters. and the length of canals, and for each patient a table. was made where the measured data were inserted.. These data were statistically analyzed and compared. with the ones found in literature. Results: The results of. measurements agree with the ones found in earlier. studies, except for the length of the inferior spinal. canals which resulted lesser than those found in. literature (4.38 mm +1.43 vs 6.1mm +2.6 ). The. frequency of the inferior spinal foramina and the data. related to the inferior spinal foramina diameter (cross. section scan) and the measurements related to the. superior spinal foramina diameter (axial scan) resulted. major than those found in earlier studies (respectively. 49% vs 38(1)\/13.34(2)%, 1.09 mm +0.4 mm vs 0.8. +0.4 and 1.24 mm + 0.29 vs 0.7 mm + 0.2).. Conclusion: This study is clinically interesting because. it has been used an implant planning software that is. daily used by operators and that permits in vivo. investigations. Furthermore, due to the possibility of. hemorrhagic accidents in the anterior region of the. mandible, the oral surgeon has to perform an accurate. planning, attending to search also the structures less known thank others"
