BACKGROUND
Implant dentistry has seen rapid and remarkable progress in recent years. The present study assessed the survival of a single implant-supported cantilever prosthesis (ISCP) in the anterior mandible.
MATERIALS AND METHODS
Sixty-four patients with missing mandibular anterior teeth of both genders were provided with a single implant and restored with cantilever screw-retained prosthesis. All were followed for 2.5 years for the implant and prosthetic success.
RESULTS
Age group of 20-30 years comprised 14 males and 10 females, 30-40 years had 10 males and eight females, 40-50 years had six males and seven females, and 50-60 years had four males and five females. The difference was nonsignificant ( > 0.05). A screw loosening was seen in total of 15 cases, in 1 at 12 months, 5 at 18 months, 2 at 24 months, and 7 at 30 months, and porcelain fracture was seen in total of eight cases, in 4 at 18 months, 1 at 24 months, and 3 at 30 months. The difference was statistically significant ( < 0.05).
CONCLUSION
Screw-retained ISCP developed complications such as screw loosening and porcelain fracture.
背景
近年来，种植牙科取得了迅速且显著的进展。本研究评估了下颌前部单颗种植体支持的悬臂式修复体（ISCP）的存留情况。
材料与方法
为64例下颌前部牙齿缺失的男女患者植入单颗种植体，并采用悬臂式螺丝固位修复体进行修复。对所有患者的种植体和修复体成功情况进行了2.5年的随访。
结果
20 - 30岁年龄组有14名男性和10名女性，30 - 40岁有10名男性和8名女性，40 - 50岁有6名男性和7名女性，50 - 60岁有4名男性和5名女性。差异无统计学意义（>0.05）。总共15例出现螺丝松动，1例在12个月时出现，5例在18个月时出现，2例在24个月时出现，7例在30个月时出现；总共8例出现瓷裂，4例在18个月时出现，1例在24个月时出现，3例在30个月时出现。差异具有统计学意义（<0.05）。
结论
螺丝固位的ISCP出现了螺丝松动和瓷裂等并发症。
