To evaluate the survival rates of dental implants placed in patients with head and neck pathologies treated with resective surgery with or without free flap reconstruction, radiotherapy alone, and/or chemotherapy.
In this study, we retrospectively analyzed the survival of intraoral dental implants placed by the same surgeon over a 12-year period from 2007 to 2019. These implants were followed up clinically and radiographically for a period of 36 months postoperatively and throughout the restorative phase.
A total of 190 patients with a total of 739 dental implants, comprising both intraoral and zygomatic implants, were included in this study. Overall, the dental implant survival rate was 95%, with a similar rate for dental implants placed in irradiated and nonirradiated bone (90% vs 93%). A lower implant survival rate was noted in implants placed in transplanted bone (79%). In cases of implant failure (n = 17), 35% (n = 6) of protheses survived and remained functional.
Our findings support the placement of dental implants in patients with benign and malignant pathologies of the head and neck to improve their quality of life. However, we highlight the need for careful surgical planning and placement by experienced clinicians.
评估在接受了切除手术（有或无游离皮瓣重建）、单纯放疗和/或化疗的头颈部疾病患者中植入牙种植体的存活率。
在本研究中，我们回顾性分析了同一位外科医生在2007年至2019年的12年期间植入的口腔内牙种植体的存活情况。这些种植体在术后36个月以及整个修复阶段均接受了临床和影像学随访。
本研究共纳入190例患者，共植入739颗牙种植体，包括口腔内种植体和颧骨种植体。总体而言，牙种植体存活率为95%，在接受照射和未接受照射的骨中植入的牙种植体存活率相似（90%对93%）。在移植骨中植入的种植体存活率较低（79%）。在种植体失败的病例（n = 17）中，35%（n = 6）的假体存活并保持功能。
我们的研究结果支持对头颈部良性和恶性疾病患者植入牙种植体以改善其生活质量。然而，我们强调经验丰富的临床医生需要进行仔细的手术规划和植入操作。
