Table 1.
Analysis of the definability of the anatomical landmarks (mental spine, median lingual foramen (MLF) and genioglossus muscle (GGM)). Five patients presented edentulous and highly atrophic (e + a) mandibles. The mean age (years) at the time of death was 87.6 years. D 1 and D 2 indicate the respective cutting guide designs 1 and 2 that were used for the osteotomy
