To assess the clinical capacity of a bioabsorbable root analog to close oroantral perforations after extraction.
In this prospective case-cohort study, 20 consecutive patients with oroantral communications greater than 2 mm were treated with a bioabsorbable root analog (RootReplica). Patients were followed up clinically and radiographically for 3 months to monitor the healing process.
Root replicas could be placed in 14 patients, whereas 6 patients required the socket to be covered with a buccal sliding flap. In the latter cases, fragmentary roots or overly large defects prohibited replica fabrication or accurate fitting of the analog, respectively. Healing was uneventful in all patients, and epistaxis, swelling, or pain was observed only in patients treated with flaps.
The method described is a valuable alternative method with which to close oroantral communications but cannot be performed in all patients because of technical limitations.
评估一种生物可吸收牙根模拟物在拔牙后封闭口腔上颌窦穿孔的临床能力。
在这项前瞻性病例队列研究中，连续20例口腔上颌窦连通大于2mm的患者接受了生物可吸收牙根模拟物（RootReplica）治疗。对患者进行了3个月的临床和影像学随访，以监测愈合过程。
14例患者能够放置牙根模拟物，而6例患者需要用颊侧滑行瓣覆盖牙槽窝。在后一种情况下，残根或过大的缺损分别妨碍了模拟物的制作或精确适配。所有患者愈合均顺利，仅在接受瓣治疗的患者中观察到鼻出血、肿胀或疼痛。
所描述的方法是封闭口腔上颌窦连通的一种有价值的替代方法，但由于技术限制，并非所有患者都能使用。
