Abstract Background Surgical orthopedic treatment of the mandible depends on the development of techniques resulting in adequate healing processes. In a new technical and conceptual alternative recently introduced by Puricelli osteotomy is performed in a more distal region next to the mental foramen. The method results in an increased area of bone contact resulting in larger sliding rates among bone segments. This work aimed to investigate the mechanical stability of the Puricelli osteotomy design. Methods Laboratory tests complied with an Applied Mechanics protocol in which results from the Control group without osteotomy were compared with those from Test I Obwegeser-Dal Pont osteotomy and Test II Puricelli osteotomy groups. Mandible edentulous prototypes were scanned using computerized .
