This open, single-cohort, multicenter, prospective study investigated the efficacy of immediately provisionalized tapered conical connection implant for single-tooth restorations in the anterior and premolar regions of the maxilla after 5 years of function.
All implants were placed in healed sites and immediately provisionalized. MBLs, soft-tissue parameters, and oral-health impact profile (OHIP) were evaluated at implant insertion, 6, 12, 24, 36, and 60 months. Paired Wilcoxon signed-rank tests and Kaplan-Meier survival analysis was used for statistical and implant survival/success analyses, respectively.
Seventy-seven patients (81 implants) completed the 5-year follow-up. The 5-year cumulative survival and success rates were 97.8%, and the mean MBL change from implant insertion to 5 years was - 0.80 ± 1.13 mm. Optimal papilla index scores were observed at 90.1% of sites at 5 years compared with 32.8% of sites at insertion. Pink esthetic score, modified bleeding and plaque indices, and OHIP showed statistically significant improvement at the 5-year follow-up.
Immediately provisionalized tapered conical connection implants promote marginal bone stability and excellent esthetic outcomes after 5 years of function.
This treatment is a viable option for patients requiring immediately provisionalized single-tooth restorations in the esthetic zone and shows favorable long-term clinical outcomes, including marginal bone stability and excellent esthetics.
本开放性、单队列、多中心、前瞻性研究调查了在前上颌和前磨牙区域,上颌愈合后即刻临时成锥形连接锥形种植体用于单牙修复 5 年的功能疗效。
所有种植体均在愈合部位植入并即刻临时修复。在种植体植入时、第 6、12、24、36 和 60 个月时评估 MBLs、软组织参数和口腔健康影响简表(OHIP)。采用配对 Wilcoxon 符号秩检验和 Kaplan-Meier 生存分析分别进行统计和种植体生存/成功率分析。
77 名患者(81 枚种植体)完成了 5 年随访。5 年累计生存率和成功率为 97.8%,从种植体植入到 5 年时平均 MBL 变化为-0.80±1.13mm。与植入时相比,5 年时 90.1%的位点观察到最佳的龈乳头指数评分,而植入时为 32.8%。粉色美学评分、改良出血和菌斑指数以及 OHIP 在 5 年随访时均显示出统计学显著改善。
即刻临时成锥形连接锥形种植体能在 5 年功能后促进边缘骨稳定性和良好的美学效果。
这种治疗方法对于需要在前牙美学区域即刻临时单牙修复的患者是一种可行的选择,并显示出良好的长期临床效果,包括边缘骨稳定性和良好的美学效果。
