The present study aimed to evaluate the long-term stability of esthetic outcomes of soft tissue around maxillary anterior single-tooth implants after 10-to-12 years of loading.
Patients who had been treated for single-tooth implants in the anterior maxilla between February 2000 and July 2002 were invited to participate in the study. All implants had been placed according to delayed implant placement and conventional loading protocols without any connective tissue graft or papilla preservation flaps. Pink Esthetic Score (PES) was rated using standardized clinical photographs to assess the esthetic outcomes of the implant treatment at the time of crown placement and at time of follow-up examination which was at least 10 years after the crown placement.
A total of 19 patients were included. The mean score of PES was 11.63 (SD 1.61; range 7-14) at baseline. After 10-to-12 years of function, a mean PES score of 11.05 (SD 2.09; range 6-14) was recorded. No significant differences were found in the esthetic outcomes, categorized based on clinically relevant levels, between the baseline and follow-up session (p>0.05).
Within limitation of the present study, it can be concluded that the esthetic outcomes of soft tissue around the maxillary anterior single-tooth implants placed using conventional implant placement technique remained stable in the long-term.
本研究旨在评估上颌前牙单颗种植体在负载10至12年后软组织美学效果的长期稳定性。
邀请2000年2月至2002年7月间在上颌前部接受单颗种植体治疗的患者参与本研究。所有种植体均按照延期种植和传统负载方案植入，未使用任何结缔组织移植或乳头保留瓣。使用标准化临床照片对粉色美学评分（PES）进行评级，以评估种植体治疗在牙冠放置时以及随访检查时（牙冠放置后至少10年）的美学效果。
共纳入19例患者。基线时PES的平均评分为11.63（标准差1.61；范围7 - 14）。在功能负载10至12年后，记录的PES平均评分为11.05（标准差2.09；范围6 - 14）。在基线和随访期间，根据临床相关水平分类的美学效果未发现显著差异（p>0.05）。
在本研究的局限性内，可以得出结论，使用传统种植技术植入的上颌前牙单颗种植体周围软组织的美学效果在长期内保持稳定。
