A key challenge in implant treatment in the esthetic zone is to provide patients with crowns and peri-implant mucosa that are in harmony with the adjacent teeth to restore both function and esthetics. The aim of the present study was to show the preliminary results of an immediate loading protocol in the maxillary esthetic zone that is designed to preserve the soft tissue.
Patients were treated with immediately loaded single-tooth implants (Seven, MIS). Implants were inserted in fresh postextraction sites or in single edentulous sites with clinically and radiologically healed bone. After 8 weeks of loading, the provisional crowns and abutments were modified as needed to enhance the esthetics of the gingival margins. Definitive restorations were delivered 4 to 6 months postoperatively.
Seventy patients were treated; 25 implants were placed in fresh extraction sites, and the remaining 45 implants were inserted in healed single edentulous sites. All implants were stable, and radiographs showed complete osseointegration after 1 year of functional loading.
The present study shows promising results for immediate loading of single implants. All implant sites fulfilled success criteria in terms of function and esthetics, and particularly promising results were seen following additional adjustments of the provisional restorations to preserve interdental papillae.
在美学区域进行种植治疗的一个关键挑战是为患者提供与邻牙协调的牙冠和种植体周围黏膜,以恢复功能和美观。本研究的目的是展示一种旨在保留软组织的即刻负重方案在上颌美学区域的初步结果。
患者接受了即刻负载单牙种植体(Seven,MIS)的治疗。种植体被插入新鲜拔牙窝或临床和影像学上愈合的单个无牙区。在负载 8 周后,根据需要对临时冠和基台进行修改,以增强牙龈边缘的美观度。术后 4 至 6 个月交付最终修复体。
共治疗了 70 名患者;25 个种植体被放置在新鲜拔牙窝中,其余 45 个种植体被植入愈合的单个无牙区。所有种植体均稳定,放射线检查显示在 1 年功能负荷后完全骨整合。
本研究显示了即刻加载单牙种植体的有前途的结果。所有种植体部位在功能和美观方面均符合成功标准,特别是通过对临时修复体进行额外调整以保留牙间乳头,取得了特别有希望的结果。
