Abstract:
Objective:To investigate the clinical outcomes of personalized polyetheretherketone (PEEK) implant in the correction of nasolabial fold depression.Methods:A total of 30 patients with nasolabial fold depression (5 males, 25 females, aged 26 to 52 years, mean 36.3 years) admitted to the Affiliated Friendship Plastic Hospital of Nanjing Medical University who want to undergo nasolabial fold augmentation from January 2019 to January 2021. All patients underwent CBCT scan and three-dimensional simulation, the personalized PEEK implant was designed and produced with CAD/CAM technique, the personalized PEEK was implanted during the operation. The patients were followed up for 3-12 months, and the wrinkle score and satisfaction were compared before operation and 3 months and 6 months after operation.Results:The depressions of nasolabial fold were significantly improved in all patients, and there were no complications such as hematoma and infection after operation. During the follow-up, there was no implant displacement or exposure, and the effect was stable and lasting. The scores of wrinkles at 3 months after operation (2.30±0.47) and 6 months after operation (2.17±0.38) were significantly lower than those before operation (4.03±0.67), and the scores of satisfaction were significantly higher than those before operation ( P<0.05). The scores of satisfaction at 3 months after operation (3.97±0.56) and 6 months after operation (4.23±0.57) were significantly higher than those before operation (1.70±0.60). The difference was statistically significant ( P<0.05). Conclusions:3D printing personalized PEEK prosthesis is effective in correcting nasolabial fold depression, and it is safe and stable, so it is recommended for clinical application.
