The aim of this study was to introduce a new surgical technique to regenerate the papilla adjacent to multiple or single implants using a novel instrument and a new incision design. A total of 10 consecutively treated patients with maxillary anterior implant-supported provisional restorations and missing interproximal papillae received a subepithelial connective tissue graft. The recipient site was prepared with a buccal incision apical to the mucogingival junction and to the defective papilla, and a palatal incision, followed by buccolingual tunneling performed with a translingual curette (EBINA). A total of 10 sites were treated and evaluated pre- and postoperatively with the papilla score based on the Jemt classification. The final prosthesis was delivered 3 months after the papilla regeneration surgical procedure. An average improvement in papilla index score from 0.8 to 2.4 was found after an average follow-up period of 16.3 months. This case series demonstrated that interimplant papilla regeneration can be successful over a period of 11 to 30 months postloading. Long-term prospective studies on tissue stability and esthetic outcomes are needed to corroborate the findings in this study.
本研究的目的是引入一种新的外科技术,使用一种新型器械和一种新的切口设计来再生单个或多个种植体相邻的乳头。共有10例连续接受治疗的上颌前牙种植体支持的临时修复体且邻间隙乳头缺失的患者接受了上皮下结缔组织移植。受区通过在龈黏膜交界处和缺损乳头根尖处做颊侧切口以及腭侧切口来制备,然后用舌侧刮匙(EBINA)进行颊舌向隧道制备。总共10个部位接受了治疗,并根据Jemt分类法在术前和术后用乳头评分进行评估。在乳头再生手术3个月后戴入最终修复体。平均随访16.3个月后,发现乳头指数评分平均从0.8提高到2.4。该病例系列表明,种植体间乳头再生在加载后11至30个月内可以成功。需要进行关于组织稳定性和美学效果的长期前瞻性研究来证实本研究的结果。
