Tooth extraction is critical for dental treatment complications. One of the most discussed topics is socket healing after extraction. The Benex system allows extraction without causing unnecessary socket expansion by removing the tooth vertically, preserving both bone and soft tissue.
To assess postoperative healing signs, symptoms, and complications using the Benex extraction system and compare it with conventional extraction among patients at Umm Al-Qura University.
Thirty-eight patients with hopeless single-rooted teeth were included. They were divided into two equal groups: one in which teeth were extracted using the conventional method and one in which extractions were performed by Benex. The Benex system for tooth extraction was performed by drilling into the root canal, followed by screw insertion. Once the extractor was properly positioned, extraction was accomplished by turning the hand screw clockwise. At baseline, the wound size was evaluated. On days 1, 3, and 7 after extraction, telephone interviews were conducted to evaluate pain and post-extraction complications using a pain scale and questionnaire. Socket healing and wound size were evaluated after 2 and 4 weeks of extraction using the healing index and HO epithelization test.
The Benex extraction system accelerated early soft-tissue healing and decreased pain and wound size compared with the control group. Conclusion. The Benex system is relatively safe and easy to use, but this does not eliminate the need for a degree of education and training. Proper selection of the case, knowledge of using the device, and implementation of that knowledge in the treatment planning are important factors in ensuring success with this system.
拔牙是牙科治疗并发症的关键环节。讨论最多的话题之一是拔牙后的牙槽窝愈合。Benex系统通过垂直拔除牙齿，在不造成不必要的牙槽窝扩张的情况下进行拔牙，从而保留骨组织和软组织。
使用Benex拔牙系统评估术后愈合体征、症状及并发症，并与乌姆古拉大学患者的传统拔牙方法进行比较。
纳入38例单根牙无法保留的患者。他们被平均分为两组：一组采用传统方法拔牙，另一组采用Benex方法拔牙。Benex拔牙系统通过钻入根管，随后拧入螺钉来进行。一旦拔牙器正确就位，通过顺时针转动手动螺钉完成拔牙。在基线时评估创口大小。拔牙后第1、3和7天，通过电话访谈使用疼痛量表和问卷评估疼痛及拔牙后并发症。拔牙后2周和4周使用愈合指数和HO上皮化试验评估牙槽窝愈合情况和创口大小。
与对照组相比，Benex拔牙系统加速了早期软组织愈合，减轻了疼痛并减小了创口大小。结论：Benex系统相对安全且易于使用，但这并不能消除进行一定程度的教育和培训的必要性。正确选择病例、了解设备使用方法并在治疗计划中运用该知识是确保该系统成功的重要因素。
