ANALYSIS REVIEWED THE PLANNING MADE FOR THE CASE. T3 RIGHT WAS PLANNED WITH MEDIAL SKIVING POTENTIALS. MOREOVER, DUE TO THE SHAPE OF THE ANATOMY THE AXIAL ANGLES OF THE SCREWS WERE 17 AND 20 DEGREES, INCREASING THE PROBABILITY TO BE SUBJECTED TO SOFT TISSUE PRESSURE WHEN INSTRUMENTING, ESPECIALLY CONSIDERING THE PROXIMITY TO THE EDGE OF THE INCISION. TWO REGISTRATION ATTEMPTS WERE DONE DURING THIS CASE, ONE FOR EACH SEGMENT. ANALYSIS REVIEWED THE PROVIDED AP AND OBL IMAGES. IN THE APPROVE REGISTRATION STAGE, AN OBSERVABLE SHIFT WAS PRESENT. NO CONFIRMATION IMAGES WERE PROVIDED TO CONFIRM THE MEDIAL DEVIATION OF RIGHT T3. SINCE THE RIGHT T3 WAS THE LAST TRAJECTORY EXECUTED, A PLATFORM OR PATIENT SHIFT COULD NOT BE RULED OUT. ANALYSIS CONCLUDED THE PROBABLE CAUSE OF THE DEVIATION OF T3 RIGHT IS MEDIAL SKIVING OF THE TOOLS DUE TO AN EXISTING SKIVING POTENTIAL IN THE PLANNING.
