目的:评价自制重建器在OSAHS口腔矫治器重建咬中的作用,探索一种操作简便、重建咬效果确切,能精确控制下颌在垂直向、前后向及前牙中线位置,且医患双方都易于接受的OSAHS口腔矫治器重建咬新方法。方法:重建器按照垂直向需打开的距离不同分为大、中、小3个型号,每种型号又按照下颌需前伸的距离不同分3个挡位,每个挡位相距5mm、重建器前端设前牙中线引导位。热凝塑料制作,含氯消毒剂消毒,可重复使用。30例研究对象(男23例,女7例),年龄(24.3±53.8)岁。采用自身对照法,分别按照OSAHS口腔矫治器的重建要求使用传统蜡和自制重建器进行咬重建,随机数字表选择使用传统蜡和自制重建器进行咬重建的先后顺序,主客观指标对自制重建器和传统蜡进行OSAHS口腔矫治器咬重建的临床效果评价。客观评价指标为:秒表记录两种方法进行咬重建全过程所需的时间;主观评价指标为:采用满意度量尺来衡量研究对象对两种咬重建的方法与过程的满意程度。SPSS11.0统计软件进行两样本均数t检验。结果:用自制重建器进行OSAHS口腔矫治器咬重建的时间为(2.11±0.64)min,用传统蜡进行OSAHS口腔矫治器咬重建的时间为(13.85±8.51)mi n,两者差异有显著统计学意义(P<0.01);满意度调查方面,30例研究对象对重建器的满意度分别为8.1±0.62,对传统蜡的满意度分别为2.5±0.81,重建器的满意度明显高于传统蜡,两者差异也具有显著的统计学意义(P<0.01)。结论:重建器设计合理,结构简单,制作方便,可重复性好,由于其能准确引导患者下颌在垂直向、前后向与前牙中线的精确位置,故使咬重建的过程简单、快捷,效果容易判断,咬重建的一次性成功率高,便于临床建立与实施标准化的技术操作规程及OSAHS口腔矫治器咬重建的医疗质量环节控制与终末控制。医患双方接受度高,适应性好,适宜临床应用推广。
OBJECTIVE: To evaluate the effect of self-made reconstructor in reconstructing bite in OSAHS oral appliances, and to explore a simple, easy-to-reconstruct bite effect that can accurately control the mandible in the vertical, anterior and posterior directions and anterior median position, A New Acceptable OSAHS Orthodontics Reconstruction Bite Method for Both Parties. Methods: reconstructor in accordance with the vertical distance to be opened is divided into large, medium and small 3 models, each model in accordance with the mandible to be extended by the distance of different sub-3 gear, each gear away from 5mm, The front end of the reconstructor is provided with anterior median guide. Thermosetting plastic, chlorine disinfectant disinfection, reusable. 30 subjects (23 males and 7 females), age (24.3 ± 53.8) years old. The self-control method was used to reconstruct the bite of the OSAHS orthodontic appliance according to the reconstruction requirements of the OSAHS orthodontic appliance respectively. The random number table was used to select the reconstruction sequence of the bite occlusion using the traditional wax and self- Subjective and Objective Indexes: Evaluation of Clinical Effect of OSAHS Oral Appliance Bite Constriction Reconstruction with Homemade Reconstructor and Traditional Paraffin Wax. The objective evaluation indexes are as follows: the stopwatch records the time required for the two methods to rebuild the bite; the subjective evaluation index is: the satisfaction measure is used to measure the satisfaction degree of the research object to the methods and processes of the two bite reconstruction. SPSS11.0 statistical software for two-sample mean t test. Results: The reconstruction time of OSAHS oral appliance was (2.11 ± 0.64) min with homemade wax reconstruction device. The reconstruction time of OSAHS with oral appliance was (13.85 ± 8.51) mi n (P <0.01). Satisfaction survey showed that the satisfaction of the 30 subjects to the reconstruction device was 8.1 ± 0.62 and that of the traditional wax was 2.5 ± 0.81, respectively The satisfaction was significantly higher than the traditional wax, the difference between the two also had significant statistical significance (P <0.01). Conclusion: The reconstruction device is reasonable in design, simple in structure, easy in manufacture and good in repeatability. Because it can accurately guide the accurate position of mandible in vertical, anterior and posterior directions and the anterior median line, the process of reconstruction is simple and quick , The effect is easy to judge, the high one-off success rate of bite reconstruction, to facilitate the clinical establishment and implementation of standardized technical procedures and OSAHS oral appliance bite reconstruction of medical quality control and end control. Both doctors and patients with high acceptance, good adaptability, suitable for clinical application.
