The primary outcome was early implant failure, defined as implant removal within six months of placement. Multivariable logistic regression models were used to calculate Odds Ratios (ORs) for failure, adjusting for patient age, gender, history of diabetes, and history of osteoporosis. Analyses were conducted at both the implant and patient levels.</div></div><div><h3>Results</h3><div>Patients in the NSAID group were significantly older (62.8 vs. 58.7 years, <em>p</em> &lt; 0.0001) and had a higher prevalence of diabetes (22.0% vs. 16.7 %, <em>p</em> &lt; 0.0001) and osteoporosis (11.0 % vs. 7.0 %, <em>p</em> &lt; 0.0001).

The free fibula flap is widely used and effective for reconstructing such defects. Traditional manual segmentation and stabilization can lead to inaccuracies; while 3D-printed guides improve cutting precision, they often overlook the stabilization of bone segments. The conventional surgical template system consists of three separate guides: a tumor removal guide, a fibula cutting guide, and a reconstruction guide, which requires manual detachment and reshaping of fibula segments before reconstruction. In contrast, the spliced surgical template system integrates an additional fibula cutting frame and reconstruction frame. This allows the fibula cutting guides to transform directly into the reconstruction guide without detaching the segments, thereby simplifying the workflow and improving stabilization accuracy. This study evaluates a spliced surgical template system and compares its accuracy in stabilizing bone segments with that of conventional systems.</div></div><div><h3>Patient and method</h3><div>A retrospective cohort study was conducted for patients who underwent mandibular tumor resection and free fibula flap reconstruction at Shanghai Ninth People’s Hospital from 01/01/2022 to 31/03/2025. Patients were divided into two groups based on whether they used conventional or spliced surgical template systems.
