目的良性肿瘤和颌骨囊肿术后，置入封闭器假体可保持手术开口，改善卫生状况。到目前为止，还没有任何报告澄清封闭器设计和治疗结果之间的关系。本研究的目的是观察三种类型的封闭器的存活率，并探讨加速拔除封闭器的因素。材料与方法研究对象组为2012年5月31日至2015年3月31日在鹿儿岛大学医院就诊的100例患者，其中73例下颌骨病变患者入选。设计并植入了三种类型的下颌封闭器，考虑了牙齿的缺失、病变的前后位置和颊舌向袋化的方向。这项研究的终点被定义为移除闭孔器。年龄、性别、剩余牙齿、原发疾病性质、原发疾病前后位置、颊舌向造袋方向、闭孔类型、置入和拔除日期是影响封闭术疗效的主要因素。早期拔除闭孔器多见于有囊肿、前牙病变和(或)咬合方向有袋的患者。结论由于闭孔器的设计对矫治器维持手术开口的能力影响很小，因此最好使用最小侵入性的设计。我们的研究结果还建议，后续检查应考虑原发疾病的类型、病变的前后位置以及口腔舌部的袋化方向。
PurposeAfter marsupialization of benign tumors and jawbone cysts, insertion of an obturator prosthesis maintains the surgical opening and improves hygiene. To date, there have been no reports clarifying the relationship between the obturator design and treatment outcomes. The purpose of this study was to examine the survival rate of three types of obturator, and to investigate the factors that expedite the removal of the obturator.Materials and MethodsThe subject group comprised 100 patients who had an obturator inserted after marsupialization at Kagoshima University Hospital between May 31, 2012 and March 31, 2015; 73 patients with lesions in the mandible were eligible. Three types of mandibular obturator were designed and inserted, considering the teeth missing, the anteroposterior position of the lesion, and the buccolingual direction of marsupialization. The endpoint of this study was defined as the removal of the obturator. The analyzed predictor values for the endpoint were age, gender, remaining teeth, nature of primary disease, anteroposterior location of primary disease, buccolingual direction of marsupialization, type of obturator, and dates of insertion and removal.ResultsNo significant differences were found in the cumulative survival rate among the three types of obturator. Early obturator removal was more frequent in patients with cysts, anterior lesions, and/or marsupialization from the occlusal directionConclusionsBecause obturator design had minimal effect on the ability of the appliance to maintain the surgical opening, it is preferable to use the least invasive design. Our findings also suggest that the follow‐up examination should account for the type of primary disease, the anteroposterior location of the lesion, and the buccolingual direction of marsupialization.
