In vitro comparison shows anatomical slots improve surgical accuracy in fibular flap techniques, suggesting optimal guide designs.

This research investigates how varying designs of cutting guides and instruments influence surgical accuracy in fibular flap surgery.
Conducted ninety model operations using three guide designs (standard, flange, anatomical) and heights (1 mm, 2 mm, 3 mm).
Utilized two cutting instruments: a piezoelectric instrument and a saw.
Digitized cut segments with computed tomography for accuracy assessment.
Anatomical and flange slots were the most accurate for vestibular and lingual segment lengths (p < 0.001).
Minor differences noted between saw and piezoelectric instrument for segment lengths and proximal angles.
U-distance median deviation for flange guides was 0.0468 mm but was not statistically significant (p = 0.067).
