application guidelines
ORAL AND MAXILLOFACIAL SURGERY Trepan They are used for preparing bone cylinders for grafting or harvesting preparations for pathological examinations. These trephines have a depth of 10 mm which is specially adapted to the requirements of oral surgery and implantology. In addition, these trephines feature depth markings at 2 mm intervals for indicating the achieved milling depth.
Punch They are essential for every oral surgery practice. These high quality skin punches are for punching out mucosa exactly and quickly when, for example, recovering implants.
Diamond saw The diamond saws are used for spreading alveolar ridges, relief incisions and other interventions.
Surgical cutters according to Lindemann › Orthoganatic surgeries › Surgical extraction of impacted or erupted teeth
Gingiva trimmer › Gingiva trimmer for gentle dilatation of the gingiva › Always used without any water-/ spray-cooling
Initial bur This initial bur is used to have a startingpiont for the use of a pilot pit so that you will not slide away when drilling
