Lowering long posterior teeth by implant anchorage for implant restoration of elderly patients with missing teeth

Objective The aim of this study was to investigate the application of implant anchorage in lowering long posterior teeth for implant restoration for elderly patients with tooth loss. Methods A total 60 teeth of 60 patients who had received treatment of lowing long posterior teeth by implant anchorage were selected from Department of stomatology in our hospital from January 2017-January 2020. The effect of orthodontic treatment, the reduction of long teeth and the apical resorption were observed. Results Among the 60 patients, the effect of orthodontic treatment on lowering long posterior teeth of 60 posterior teeth was good, and 49 patients completed implant restoration, of which 2 patients had not finished orthodontic treatment, and 5 implant anchorage loosened and fell off before the completion of the pressing movement of the posterior teeth. The vertical distance of the elongated molars to the palatal plane before treatment was (27.53 ±1.77) mm, the vertical distance after treatment was (25.17 ±1.36) mm and the average reduction value of elongation molar was (2.16±0.19) mm, and the difference was significant between before and after treatment (P<0.05). Before and after treatment, there was no significant difference in the crown and root of the teeth (P>0.05). Conclusion The implant anchorages have good effects on the elderly patients with missing teeth, which can significantly lower the overlong posterior teeth and have no obvious effects on absorption of the root apex, and can be widely used in clinical practice.
