Little is known about immediate implant placement in head and neck cancer patients. We studied implant survival and functional outcomes of overdentures fabricated on implants placed immediately after removal of the lower dentition during ablative surgery or preceding primary radiotherapy (RT).
Inclusion criteria were primary head and neck cancer, dentate lower jaw, and indication for removal of remaining teeth. Two implants to support a mandibular overdenture were placed immediately after extraction of the dentition during ablative surgery, or prior to starting primary radiotherapy. Standardized questionnaires and clinical assessments were conducted (median follow-up 18.5 months, IQR 13.3).
Fifty-eight implants were placed in 29 patients. Four implants were lost (implant survival rate 93.1%). In 9 patients, no functional overdenture could be made. All patients were satisfied with their dentures.
Combining dental implant placement with removal of remaining teeth preceding head neck oncology treatment results in a favorable treatment outcome.
对于头颈部癌症患者，我们对即刻种植知之甚少。我们研究了在下颌牙齿切除后的即刻种植和在根治性放疗前即刻种植，以此来修复种植体支持的覆盖义齿，并对其种植体的存活率和功能结果进行评估。
纳入标准为头颈部原发性肿瘤、下颌有牙、且需拔牙的患者。在下颌牙齿切除的即刻种植术或根治性放疗前即刻种植术，分别植入 2 个种植体以支持下颌覆盖义齿。对患者进行标准化问卷调查和临床评估（中位随访时间 18.5 个月，IQR 为 13.3）。
29 例患者共植入 58 个种植体，其中 4 个种植体失败（种植体存活率为 93.1%）。有 9 例患者无法制作功能性覆盖义齿。所有患者对义齿均满意。
在头颈部肿瘤治疗前即刻种植与拔牙联合应用，可获得良好的治疗效果。
