Claim 15:
16. A method of verifying an osteotomy trajectory in a dental implant procedure using an osteotomy trajectory verification apparatus, comprising:
providing the osteotomy trajectory verification apparatus, the osteotomy trajectory verification apparatus including:
a straight rod portion extending along a first axis in a first direction;
a sliding arm slidably coupled to the straight rod portion and configured to slide along a sliding direction on the straight rod portion along the first axis without moving in a direction different from the sliding direction, the sliding arm comprising:
a sliding portion slidably coupled to the straight rod portion to slide along the sliding direction,
a pointing portion consisting of a single tip protruded along a second axis in a second direction, the second axis being parallel to the first axis, and
an extending portion having a first side attached to the sliding portion and a second side attached to the pointing portion; and

a fixed arm coupled to the straight rod portion, wherein the fixed arm is configured to mount a drill thereon to align the drill to extend along the second axis with a tip of the drill facing toward the single tip of the pointing portion on the second axis and the drill is mounted at the fixed arm, or a drill protrusion is attached to the fixed arm to extend along the second axis with a tip of the drill protrusion facing toward the single tip of the pointing portion on the second axis;

inserting the drill or the drill protrusion into an opening of a slot planted on a portion of the oral cavity of the patient, wherein the opening of the slot guides the drill or the drill protrusion in a direction of the osteotomy trajectory;
sliding the sliding arm via the sliding portion along the sliding direction outside of the oral cavity to move the single tip of the pointing portion along the second axis; and
verifying the osteotomy trajectory based on the movement of the single tip of the pointing portion along the second axis.
