Abstract:

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.

摘要：

目的: 评价数字化聚醚醚酮囊肿塞在颌骨囊肿开窗减压术中的治疗效果及其优缺点。方法: 选取2021—2022年于同济大学附属口腔医院收治的颌骨囊肿患者13例，均采用开窗减压术配合术后使用数字化聚醚醚酮囊肿塞治疗，通过临床检查及影像学资料，评估佩戴数字化聚醚醚酮囊肿塞对开窗减压术治疗颌骨囊肿的疗效。术后定期随访，观察囊腔缩小、新骨形成、并发症发生情况及囊肿塞佩戴满意度等。结果: 开窗手术同期拔除囊腔内埋伏牙者存在轻度张口受限、颊部肿胀等情况。问卷调查显示，除1例患者对囊肿塞外观不满意，其余各项指标均达到可接受或满意。术后3、6、9、12个月测得的新骨沉积率分别为71.03% (59.37%，82.84%)、82.75% (77.25%，88.66%)、89.93% (86.41%，95.08%)和94.21% (90.21%，95.09%)；术后3、6、9、12个月测得的囊腔缩小率分别为96.91% (92.47%，98.65%)、100% (98.36%，100%)、100% (99.79%，100%)和100% (100%，100%)。结论: 数字化聚醚醚酮囊肿塞凭借其独特的材料优势和设计优势，在开窗减压术的应用中取得了良好的治疗效果，患者佩戴满意度高，值得进一步推广。
