Abstract

Objective To study the low-elongation effects of micro-screw planting resistance with the micro-screw planting resistance.Methods Forty-seven cases of patients with micro-screw planting resistance in our hospital from May 2014 to April 2016 were retrospectively analyzed, and the materials and treatment effects of these patients were investigated and analyzed. Results The vertical distance from the molar to the plane of the palate before and after the treatment were(27.1 ± 6.8) mm and(17.8 ± 3.7) mm respectively,with significant difference(P<0.05). Patients with elongated molars depressed average length of(9.30 ±2.81) mm. 2 of the 47 patients had a loosening of the screw,with an incidence of 4.3%, and got good stability after re-implantation, no screw fracture, periodontitis, or gum infection. 39 were satisfied with the treatment, 4 were satisfied with the treatment, 3 were not satisfied with the treatment, and the satisfaction was 83.0%. Conclusion The low-elongation effects of micro-screw planting resistance with the micro-screw planting resistance are good.
- Maxillary molar,
