目的:探讨下前牙缺失后种植支持单端桥修复的近期临床效果。方法:33例缺失两颗下颌前牙的患者(男性15例,女性18例,年龄20-54岁,平均42.6岁),共33个修复体(均为种植支持的单端桥),植入种植体33枚。观察方法为临床检查和X线检查,修复后平均追踪30个月(15-44个月)。结果:所有病例在修复后至最后一次复查时未见种植体脱落,所有修复体均无松动、破损或折断。修复效果良好,患者满意。修复满1年、2年和3年病例平均骨吸收分别为0.94mm、1.18mm和1.35mm。讨论:悬臂梁设计的种植修复临床效果虽然存在争议,但本研究中下前牙区的种植支持单端桥在短期内并未出现明显的并发症,边缘骨吸收也在允许的范围内。结论:严格掌握适应症,下前牙缺失后单颗种植体支持单个桥体的单端桥设计,在减少种植体数目,降低医疗费用的同时其近期临床修复效果满意。
Objective: To investigate the short-term clinical effect of implant-supported single-ended bridge repair after anterior tooth loss. METHODS: Totally 33 patients with missing mandibular anterior teeth (15 males and 18 females, aged 20-54 years, mean 42.6 years) were enrolled in this study. A total of 33 prostheses (all implant-supported single-ended bridges) 33 implants The observation methods were clinical examination and X-ray examination. After repair, the average follow-up was 30 months (15-44 months). Results: No implant was found in all cases from the time of repair to the last review. All the prosthesis did not loosen, break or fracture. Good repair, patient satisfaction. The average bone resorption of 1 year, 2 years and 3 years after repair was 0.94mm, 1.18mm and 1.35mm respectively. Discussion Although the clinical effect of implantable cantilever design is controversial, there is no obvious complication in the short-term support of implanting single-ended bridge in the lower anterior teeth area. The marginal bone resorption is also within the allowable range. Conclusions: Strictly understand the indications, the design of single-ended bridge with single implants supported by single implants after the loss of the lower anterior teeth is satisfactory in reducing the number of implants and reducing the medical costs in the near future.
