The 3D\u2010PITM was removed 6\u20139 months post\u2010bone regeneration surgery. Cone\u2010beam computed tomography (CBCT) data allowed for digital comparison between the actual titanium mesh and the preoperative design, analyzing the overall deviation and deformation angle of the titanium mesh. Additionally, morphology modification of the augmented areas was analyzed, and the volume was calculated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The deviation of the titanium mesh immediately post\u2010bone regeneration surgery from the preoperative design was 0.93\u2009\u00b1\u20090.22\u2009mm. The maximum deformation angle of the titanium mesh immediately post\u2010bone regeneration surgery was 21.49\u00b0, averaging 10.85\u00b0\u2009\u00b1\u20096.70\u00b0. Correlation analysis indicated that a larger deformation angle post\u2010bone regeneration surgery resulted in a greater deviation from the preoperative titanium mesh design. With one failure case excluded, the average actual bone augmentation achieved was 92.83%\u2009\u00b1\u200926.12% of the design. Due to the small sample size, no significant correlation was found between the actual percentage of bone fill and the Root Mean Square (RMS) deviation and deformation angle of the titanium mesh.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Although 3D\u2010PITM\u2010protected bone regeneration provided effective bone augmentation, a noticeable deviation remained between the titanium mesh's actual position and preoperative design.
