[Clinical application of two extraction methods of impacted teeth combined with immediate implantation]

To observe the effects of immediate implantation combined with high-speed turbine minimally invasive technology and traditional technology on postoperative analgesia, mouth opening and alveolar bone resorption after removal of complex impacted teeth.

Eighty patients with impacted teeth treated in our hospital from January 2014 to December 2018 were randomly divided into 2 groups: experimental group and control group with 40 cases in each group. Patients in the experimental group were treated with high-speed turbine minimally invasive surgery combined with immediate implantation, while patients in the control group were treated with traditional surgery combined with immediate implantation. Differences in alveolar bone resorption, pain, swelling, limited mouth opening, intact extraction socket and complications were compared between the two groups. SPSS 19.0 software package was used to perform statistical analysis.

Three months after operation, the implant height of the maxillary anterior teeth, maxillary molar, mandibular anterior teeth and mandibular molar areas in the experimental group was significantly lower than that in the control group. One day after operation, the VAS score of the experimental group was significantly lower than that of the control group (P<0.05). Three months after operation,there was no significant difference in VAS score between the two groups (P>0.05); but intact extraction socket, swelling degree and mouth opening limitation of the experimental group were significantly lower than those of the control group. The root fracture, adjacent teeth loosening, gingival tear, lingual bone plate fracture of the experimental group were significantly lower than those of the control group.

High-speed turbine minimally invasive treatment combined with immediate implantation after extraction of complex impacted teeth can significantly increase alveolar bone resorption, relieve swelling and preserve intact extraction socket, reduce pain and complications after operation. It is recommended to be popularized in clinic.
