牙列缺损伴错(牙合)畸形的患者,一般按常规修复很困难,即使勉强进行修复,也不易达到恢复美观和提高咀嚼效率的目的.这类病人如在修复前对妨碍修复的错(牙合)畸形先行矫正治疗,通过矫正与修复相结合的方法,则可以收到比较满意的效果.临床资料与矫治方法自1995年8月到1999年4月,应用正畸与修复相结合的方法治疗牙列缺损伴有不同类型的局部错(牙合)畸形患者24例,男11例,女13例,年龄14—49岁.其中8例是伴前牙散在间隙.我们采用固定矫治器先集中间隙,而后做固定修复体,对于牙体形态异常,如过小牙,我们考虑到修复的设计,而留以修复所需间隙,这样既解决了中线偏斜问题,又使牙弓的对称性得到了调整,以利于咬合平衡.6例是伴前牙深覆(牙合),深覆盖,我们采用固定矫治器配合平、斜面导板,待覆(牙合)覆盖关系得到改善后再进行义齿修复,这样解决了由于咬合创伤所引起的牙周病、创伤性龈炎,并且使面高比达到正常,面型趋向美观.7例是缺牙区相邻牙的倾斜.
Dentition defect with malocclusion (malocclusion) patients, the general repair is very difficult to repair, even barely restored, but also difficult to achieve the purpose of restoration of beauty and improve chewing efficiency such as patients before repair to prevent the repair of the wrong ( Occlusion) deformity correction treatment, through the combination of correction and repair methods, you can receive more satisfactory results. Clinical data and correction methods from August 1995 to April 1999, the application of orthodontic and repair combined Methods 24 cases of dentition defect with different types of local malocclusion were treated in this study, including 11 males and 13 females, aged 14-49 years old, including 8 cases with anterior teeth scattered in the gaps.We used a fixed appliance First focus on the gap, and then do a fixed prosthesis, abnormal tooth morphology, such as too small teeth, we consider the design of the repair, leaving to repair the required gap, so that both the central line deflection problem, but also to the arch Symmetry has been adjusted to facilitate the balance of bite .6 cases with deep overbite with anterior teeth, deep coverage, we use a fixed appliance with flat, bevel guide, to be covered (occlusal) after the relationship between coverage improved Denture repair, thus solving the occlusion Trauma caused by periodontal disease, traumatic gingivitis, and make the aspect ratio to normal, facial features tend to look beautiful .7 cases of edentulous adjacent teeth tilt.
