Digital polyetheretherketone cyst plug in fenestration decompression:An applied research
Objective:To evaluate the therapeutic effect,advantages,and disadvantages of digital polyetheretherketone cyst plug in fenestration decompression of jaw cyst.Methods:A total of thirteen patients with jaw cyst who underwent surgery in Tongji University Stomatological Hospital from 2021 to 2022 were treated with fenestration decompression and digital polyetheretherketone cyst plug after operation.Through clinical examination and imaging data,the effect of digital polyetheretherketone cyst plug was evaluated.Postoperative follow-up was conducted regularly to observe the shrinkage of cyst cavity,the formation of new bone,the occurrence of complications and the wearing satisfaction of cyst plug.Results:In some cases,mild mouth opening restriction and cheek swelling appeared in those who pulled out the impacted teeth in the capsule cavity at the same time of fenestration.Questionnaire survey showed that all indexes were acceptable or satisfactory except one patient who was dissatisfied with the appearance of cyst plug.The new bone deposition rates measured in 3,6,9,12 months after operation were 71.03%(59.37%,82.84%),82.75%(77.25%,88.66%),89.93%(86.41%,95.08%),and 94.21%(90.21%,95.09%)respectively.The reduction rates of cysts measured in 3,6,9,12 months after operation were 96.91%(92.47%,98.65%),100%(98.36%,100%),100%(99.79%,100%),and 100%(100%,100%)respectively.Conclusion:Digital polyetheretherketone cyst plug,with its unique material advantages and design advantages,has achieved good therapeutic effect in the application of fenestration decompression,and patients'wearing satisfaction is high,which is worthy of further promotion.
