Effect of High‐Speed Turbine–Assisted Minimally Invasive Tooth Extraction Combined With Collagen Sponges in Patients With Complex Impacted Teeth

Objective This study aimed to elucidate the effect of minimally invasive tooth extraction using a high‐speed turbine combined with collagen sponges in patients with complex impacted teeth. Methods Eighty patients with complex impacted teeth were categorised into a control group (received piezosurgery extraction treatment) and an observation group (received high‐speed turbine‐assisted minimally invasive extraction plus medical collagen sponge treatment). Outcome measures included intraoperative blood loss, integrity of the tooth socket, degree of postoperative mouth‐opening limitation, VAS scores, degree of swelling, postoperative complications and the Pink Aesthetic Score (PES). Results The observation group exhibited less intraoperative blood loss and superior tooth socket integrity compared to the control group ( p < 0.05). The degree of mouth‐opening limitation in the observation group was better than that in the control group ( p < 0.05). VAS scores on postoperative Days 3 and 7 were significantly lower in the observation group compared with the control group ( p < 0.05). On postoperative Day 5, the swelling rate was lower in the observation group than the control group ( p < 0.05). Furthermore, the incidence of postoperative complications was reduced and the PES index was higher in the observation group compared with the control group (both p < 0.05). Conclusion Minimally invasive tooth extraction using a high‐speed turbine combined with collagen sponges effectively reduces postoperative pain, swelling, and complications in patients with complex impacted teeth, while improving aesthetic outcomes.
