Neuroclusal rehabilitation and planas direct tracks in the posterior crossbite treatment

ABSTRACT Objective: To evaluate the effectiveness of neuroclusal rehabilitation treatment using Planas Direct for posterior crossbite correction. Methods: This is a clinical study in which 43 children were selected, of both sexes, between 3 and 6 years old, diagnosed with posterior crossbite and midline deviation. Interviews were conducted with the parents in order to ascertain the practice of harmful habits. The treatment was based on neuroclusal rehabilitation in order to investigate and eliminate the occlusal obstacles which depreciate the stomatognathic system. The aim of the study was also to reprogram the affected neuromuscular activity. Planas direct were performed on crossed teeth in order to restructure the neuroclusal area and the stomatognathic system, as well. Epi Info software, 3.5.4 for Windows, through the distribution of frequencies and the Pearson chi-square test were used for statistical analysis. Results: Occlusal restoration in 79% of children was performed however 21% abandoned treatment. The crossbite and midline correction period ranged from from 14° to the 91° treatment. Significant associations of the variables were observed as follows: deleterious habits (p = 0.0001) and midline deviation (p = 0.0001) at the beginning or end of treatment. Conclusion: It was concluded that the neuroclusal rehabilitation and Direct Slopes Planas were effective in correcting the posterior crossbite.

摘要
研究目的：评估采用Planas Direct进行神经咬合康复治疗矫正后牙反𬌗的有效性。
研究方法：本研究为临床研究，纳入43名年龄3~6岁、男女不限的后牙反𬌗伴中线偏斜患儿。对患儿家长开展访谈，以明确其有害口腔习惯的发生情况。本次治疗以神经咬合康复为核心，旨在探查并消除损害口颌系统的咬合干扰，同时对受累的神经肌肉活动进行重新编程。针对反𬌗牙齿实施Planas Direct治疗，以重塑神经咬合区域及口颌系统。统计学分析采用Epi Info 3.5.4 Windows版软件，通过频数分布及Pearson卡方检验完成。
研究结果：79%的患儿完成了咬合重建治疗，21%的患儿中途放弃治疗。反𬌗及中线矫正的治疗周期为14天至91天。观察到变量间存在显著关联：有害习惯（p=0.0001）及中线偏斜（p=0.0001）与治疗起始或结束阶段相关。
研究结论：本研究证实，神经咬合康复联合Planas Direct治疗可有效矫正后牙反𬌗。
