Abstract

The object of our study was to contribute to anatomical knowledge of this region with data on the prevalence, number and location of lingual foramina (LF) in dentate and edentate macerated mandibles from Brazilian individuals, differen­tiating them by sex and race. In this way we hope to help dental surgeons with their planning prior to implant placement in the anterior mandibular region. 103 macerated mandibles were analysed. The prevalence, number and location of LF were analysed in the median (MLF) and lateral (LLF) regions and the median (AMLF) and lateral (ALLF) alveolar process regions. Measurements for their location were taken with a digital calliper. 99% of the mandibles presented at least 1 MLF, 82.5% at least 1 LLF, and the frequency of ALLF was 67%. In dentate mandibles, MLF were located in the region superior to the genial spine, and in edentate mandibles in the regions superior and inferior to the genial spine. LLF were located in the middle region in both dentate and edentate mandibles. The height of the symphysis was significantly greater in dentate than in edentate cases. The distance from the alveolar crest (AC) to the MLF was significantly greater in dentate than in edentate mandibles. LF are constant structures, with MLF found more frequently than LLF. Mandibles which present a smaller measured distance from the base of mandible to AC present MFL and LLF closer to AC, implying a greater risk of complication during implant placement.
