To date, few reports have combined patient-specific guides with piezoelectric devices for gap arthroplasty in children. This study evaluates the feasibility, accuracy, and early outcomes of this approach, hypothesizing that the combination of narrow-slit surgical guides and piezoelectric osteotomy provides safe and reproducible results in pediatric TMJ ankylosis.
A prospective pilot study was conducted on \[n\] children (mean age \[x\] years) with TMJ ankylosis. Virtual surgical planning and CAD/CAM fabrication were used to design patient-specific guides with narrower osteotomy slits (width \[x\] mm) to allow precise bone removal and improved condylar fit. Preoperative and postoperative CT scans were superimposed to measure the accuracy of gap creation. Functional outcomes included maximal interincisal opening (MIO) at 1, 3, and 6 months, and complications.

accuracy of the guide
Follow-up imaging was performed 1 week postoperatively using computed tomography (CT). Digital superimposition of the preoperative virtual plan and postoperative CT scans was carried out to assess the accuracy of osteotomy execution.
