Anatomical landmarks. Cm (Condylar midpoint), Ar1 (Articulare 1), Ar2 (Articulare 2), Go (Gonion), Ba (Basion point), Inc (Incisal point), Mol (Molar point). The implant points were located on the right side: ImpA (Implant A) and ImpB (Implant B). The following two lines were defined: ML (Mandibular line) from Go to Ba, defined at the right side; IL (Implant line) going through ImpA-ImpB. For specific definitions of the anatomical landmarks see Stoustrup et al. 2008 .
