Abstract

Abstract: PURPOSE: To evaluate the long-term effectiveness of intruded upper molar with orthodontic mini-screw and the long-term stability of the lower molar restored with dental implant. METHODS: Twenty-four patients with excessive growing upper molar were chosen. The upper molars were intruded by orthodontic mini-screw to increase the bite distance, and then restored with dental implant. The height of molar and the height of bone around the implant were measured on the lateral cephalometric films and panoramic films to analyze the long-term effect of molar intrusion and implantation. The data were analyzed with SPSS18.0 software package. RESULTS: There was significant difference between the length of upper molar before and after intrusion, the upper molars were intruded (2.7±0.3)mm 3.5 months after orthodontic mini-screw; there was no significant difference after 1 year with retainer and implant restoration. The height of bone around the implant decreased 1.2 mm but without significant difference. CONCLUSIONS: With the upper molar intruded by orthodontic mini-screw , more bite space can be obtained to restore lower molar with dental implant, and the long-term effect of upper molar intrusion and lower molar implant are stable.
