The aim of this study was to compare the aesthetic outcome of single implants in extraction sockets and healed ridges of the anterior maxilla by means of the pink aesthetic score/white aesthetic score (PES/WES) index.
This retrospective study was based on data from 103 patients (43 males, 60 females) aged 24-65 years (mean age 41.4 ± 13.8 years) who had been successfully treated with a single implant in the anterior maxilla, in four different clinical centres. Forty-two patients (mean age 46.5 ± 15.1 years) were treated with a single implant in a fresh post-extraction socket (immediate implant treatment, IIT), while 61 patients (mean age 38.0 ± 11.8 years) were treated with a single implant in a healed site (conventional implant treatment, CIT). Two independent calibrated examiners applied the PES/WES index to the 103 single-tooth restorations, respectively 3 months and 3 years after implant placement.
A few biological (4.8%) and prosthetic (8.7%) complications were reported. Both IIT and CIT yielded satisfactory aesthetic outcomes. At the delivery of the final restoration, a PES/WES score of 16.6 ± 2.6 and 15.7 ± 3.0 was reported for IIT and CIT, respectively: this difference was not statistically significant. A higher decrease in the PES/WES score was observed with CIT over time. At 3 years, a PES/WES score of 16.4 ± 2.8 and 15.2 ± 3.3 was reported for IIT and CIT, respectively: this difference was statistically significant. IIT seemed to yield better aesthetic outcomes in young patients (≤30 years), with implants placed in central incisor/cuspid areas, in the presence of bone contouring.
Both immediate and conventional single-implant treatment in the anterior maxilla can yield satisfactory aesthetic outcomes, when performed by experienced clinicians in well-selected cases. Further studies are needed to confirm these results.
本研究旨在通过粉色美学评分/白色美学评分（PES/WES）指数比较在前上颌骨拔牙窝和愈合牙槽嵴中进行单颗种植体修复的美学效果。
本回顾性研究基于来自四个不同临床中心的103例患者（43例男性，60例女性）的数据，年龄在24至65岁之间（平均年龄41.4±13.8岁），这些患者均在前上颌骨成功接受了单颗种植体治疗。42例患者（平均年龄46.5±15.1岁）在新鲜拔牙窝中接受单颗种植体治疗（即刻种植治疗，IIT），而61例患者（平均年龄38.0±11.8岁）在愈合部位接受单颗种植体治疗（传统种植治疗，CIT）。两名独立校准的检查人员分别在种植体植入后3个月和3年对103颗单颗牙修复体应用PES/WES指数。
报告了一些生物学（4.8%）和修复（8.7%）并发症。IIT和CIT均产生了令人满意的美学效果。在最终修复体交付时，IIT和CIT的PES/WES评分分别为16.6±2.6和15.7±3.0：这种差异无统计学意义。随着时间的推移，CIT的PES/WES评分下降幅度更大。在3年时，IIT和CIT的PES/WES评分分别为16.4±2.8和15.2±3.3：这种差异具有统计学意义。IIT似乎在年轻患者（≤30岁）、种植体植入中切牙/尖牙区域且存在骨轮廓修整的情况下产生更好的美学效果。
由经验丰富的临床医生在精心挑选的病例中进行前上颌骨的即刻和传统单颗种植体治疗，均可产生令人满意的美学效果。需要进一步研究来证实这些结果。
