研究目的:

通过单中心、前瞻性、随机、单盲、平行对照试验: 1. 验证新型双合垫矫治器改进高角下颌后缩患儿牙颌面生长引导的疗效,从矢状向、垂直向、横向三个维度评价患儿牙、颌、面的生长发育,以及对牙周、上气道、颞下颌关节的影响。相较于传统双合垫矫治器,验证新型双合垫矫治器不但垂直向控制显著更优,且其他主要有效性和安全性指标无显著差异或者更优; 2. 评估新型双合垫矫治器临床应用的可行性和患儿可接受度; 3. 探索新型双合垫矫治器临床应用的相关机制; 4. 初步评估新型双合垫矫治器临床应用的卫生经济学和转化价值。  

Objectives of Study:

Through single-center, prospective, randomized, single-blind, parallel controlled trials: 1. To verify the effectiveness of the new twin-block appliance in improving the guidance of dental and maxillofacial growth in children with hyperdivegent mandibular deficiency, evaluate the growth and development of the teeth, jaws, and face from three dimensions: sagittal, vertical, and transverse; to evaluate the effect on periodontal, upper airway, temporomandibular joint. Compared with the traditional twin-block appliance, it is verified that the new twin-block appliance not only has significantly better result of vertical control, but also has no significant difference or better results in other main effectiveness and safety indicators; (2) Assess the feasibility of the clinical application of the new twin-block appliance and the acceptability of patients; (3) Exploring the relevant mechanism of the clinical application of the new twin-block appliance; (4) Preliminary assessment of the hygienic economics and transformational value of the clinical application of the new twin-block appliance.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1. 年龄9-14岁,性别不限;
2. 突面畸形,颏部形态差,下颌后缩,ANB>5°,上颌骨发育基本正常,上颌以牙性前突为主;
3. 垂直生长型为高角倾向的儿童,35° 4. 上气道狭窄;
5. 受试者依从性良好,能按要求佩戴矫治器并定期复查。

Inclusion criteria

1. Aged 9-14 years, no gender limit;
2. Protrusion deformity, poor chin morphology, mandibular retrusion, ANB > 5 degree, maxillary development is basically normal;
3. Children with long-face growth pattern, 35 degree < SN-MP < 45 degree; (Ethical considerations: children treated with traditional twin-block appliances are prone to elongation of the posterior teeth, causing the backward and downward rotation of mandibular. The increase in face height will aggravate the original long face and bring ethical issues; therefore, the subjects included in this study are children with high mandibular plane angle, and the SN-MP is controlled within 45 degree, these children show a tendency of long-face growth pattern, but have not yet developed into severe long face. Even if the face height increase after treatment of traditional twin-block appliances, it is still acceptable.)
4. The upper airway is narrow;
5. Subjects had good compliance and were able to wear appliances as required and rechecked regularly.

排除标准:

1. 根据改良颈椎分析法,Cvs4期之后,生长发育高峰期已过的患儿;
2. 有颞下颌关节紊乱症状者;
3. 乳磨牙松动者;
4. 并发全身性疾病患者。

Exclusion criteria:

1. Children who have passed pubertal peak according to the modified cervical spine analysis method (Cvs4 stage);
2. Children have symptoms of temporomandibular joint disorders;
3. Children with loose deciduous molar;
4. Patients with systemic disease.
