24例磨牙压低及种植义齿修复长期疗效观察
|
摘要
目的 :观察经正畸种植支抗压低的上颌磨牙的远期疗效以及种植义齿的长期稳定性。方法 :选择在我院进行种植修复的患者24例,伸长磨牙32颗,经正畸种植支抗压低上颌磨牙后,行下颌种植义齿修复32颗。对患者手术前、后的头颅侧位片及曲面体层片进行测量,测量手术前、后磨牙高度以及种植体周围骨量变化,分析磨牙压低以及种植修复体的长期疗效,采用SPSS18.0软件包分析对测量数据进行t检验。结果:上颌磨牙高度经种植支抗压低后,可以获得足够的咬合空间。压低时间平均为3.5个月,平均可以获得(2.7±0.3)mm的咬合空间。经保持器保持及下颌种植义齿修复后1年,未见明显变化。下颌磨牙行种植义齿修复1年后效果良好,周围骨高度未见明显变化。结论:对上颌磨牙行种植支抗压低后,可以获得充分的咬合空间,压低效果及种植义齿修复后长期效果稳定。
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.
