PURPOSE: To analyze the clinical efficacy of 3D-printing individualized titanium mesh (3D-PITM) technology in the treatment of complex alveolar bone defects.
METHODS: A total of 22 patients with complex alveolar bone defects were selected for treatment with 3D-PITM. Mimics 21.0 software was used to reconstruct the CBCT data before surgery, immediately after surgery, and 6 months after surgery. Alveolar bone width and bone height increase were measured and postoperative complications were recorded. Buccal keratinized gingival width was measured before and after bone grafting, and the correlation between the change of keratinized gingival width and the amount of bone grafting immediately after surgery was analyzed.
RESULTS: Six months post-grafting, there was significant increase in horizontal bone gain (4.21±1.03) mm and vertical bone gain (4.24±1.12) mm (P＜0.001). One patient experienced postoperative infection, with no other complications reported. Six months after grafting, the width of the keratinized gingiva on the buccal side was significantly reduced by (1.19±0.20) mm compared to pre-graft measurements (P＜0.001). The reduction in keratinized gingival width was positively correlated with the immediate postoperative bone volume (r=0.80, P＜0.001).
CONCLUSIONS: 3D-PITM can effectively complete complex bone augmentation with low incidence of complications, but there is a reduction in the buccal keratinized gingivitis after bone augmentation, and the reduction is positively correlated with the amount of bone grafting immediately after surgery.
