项目摘要

The purpose of the present study is to investigate the use of an dental implant as a supplementary retainer in patients with maxillofacial and surgical prostheses applied to a surgical defect after resection of the jaw bones, which are not well fitted to the defect. Advance intreatment of malignant tumors.have been associated with the recent marked improvement in the cure rate of malignant tumors. It is also true in maxillofacial tumors, which are aggressively treated with surgical procedured, i.e., resection of carcinoma lesions and affected Jaw bones. However, primary disease is cured by extensive radical therapy, but its surgical sequelae, including functional disorders in mastication, pronunciation, swallowing, and esthetic problems due to jaw deformation are increasing. Since maxillofacial prosthesis used for such substantial defect of the jaw bone is hard to be fitted, the dental implant is used as a retainer.Maxillofacial prosthesis is generally stable even in edentulous jaw itself or with an obturator for a small anilateral jaw defect, and using of dental implant provides further favorable and stable fitness of prosthesis. However, if a jaw defect is extensive, a great strain is loaded on the dental implant in return for stable fitness. To attain stable fitness of maxillofacial and surgical prostheses by preventing the overturn of a applied prosthesis after inserting the dental implant, we have developed maxillofracial and surgical prosthses and devised a new retaining system for patients with problems of prosthetic application.

本研究的目的是调查使用的牙科种植体作为一个补充固位体的患者的颌面部和外科手术修复适用于手术缺损切除后的颌骨，这是不适合的缺陷。近年来恶性肿瘤治愈率的显著提高与恶性肿瘤治疗的进展有关。这也是真实的颌面部肿瘤，这是积极的治疗与外科手术，即，切除癌病变和受影响的颌骨。然而，原发病通过广泛的根治性治疗得以治愈，但其手术后遗症，包括咀嚼、发音、吞咽功能障碍以及由于颌骨变形引起的美学问题正在增加。由于用于这种颌骨实质性缺损的颌面部修复体很难适合，因此使用牙种植体作为固位体，即使在无牙颌本身或对侧颌骨小缺损的情况下使用闭孔器，颌面部修复体通常也是稳定的，并且使用牙种植体进一步提供了良好和稳定的修复体适合性。然而，如果颌骨缺损是广泛的，一个很大的应变是加载在牙种植体上，以换取稳定的健身。为了通过防止插入牙种植体后应用的修复体翻转来实现颌面和外科修复体的稳定适合性，我们开发了颌面和外科修复体，并为有修复体应用问题的患者设计了一种新的固位系统。
