The aim of the study was to report the use of an elastodontic therapy in a growing patient affected by Dentinogenesis Imperfecta, second class malocclusion, deep bite and lower arch crowding from the deciduous dentition to permanent one.
At first, the 5-year-old patient was treated with an elastodontic device known as "Nite-Guide". When the patient was 7 years old, during her first permanent molars and incisors eruption and after optimal house-practices, an Occlus-o-Guide Series G was placed at night and on daylight (two hours a day) performing exercises aimed to activate facial muscles and facilitate the deep bite reopening. At 9 years of age, with totally deep bite resolution, she used the Occluso-Guide only at night to hold down previous results and follow patient's dental growth. At 11 years of age, after successful teeth switching, we prescribed an Occlus-o-Guide Series N, which is functional for permanent dentition and guaranteed an eruptive guide for last dental elements.
This clinic case could be considered an example of approach for all those patients with systemic and/or dental diseases that do not allow adequate dental retention, which is necessary for most orthodontic appliances; elastodontic devices do not require adequate dental retention and define a minimum intervention on the surfaces of the teeth.
本研究旨在报告在一名患有牙本质发育不全、二类错牙合、深覆牙合以及从乳牙列到恒牙列下牙弓拥挤的生长发育期患者中使用弹性正畸疗法的情况。
起初,该5岁患者使用一种名为“夜间引导器”的弹性正畸装置进行治疗。当患者7岁时,在其第一恒磨牙和恒牙萌出期间,且在进行了最佳的家庭训练后,夜间及白天(每天两小时)佩戴咬合引导器系列G,进行旨在激活面部肌肉并促进深覆牙合重新打开的训练。9岁时,深覆牙合完全解除,她仅在夜间使用咬合引导器以维持先前的治疗效果并跟踪患者的牙齿生长情况。11岁时,在成功完成牙齿替换后,我们为其开具了咬合引导器系列N,该装置对恒牙列起作用,并为最后萌出的牙齿提供萌出引导。
该临床病例可被视为所有患有全身性和/或牙齿疾病而无法实现足够牙齿固位的患者的治疗方法示例,而足够的牙齿固位对于大多数正畸矫治器来说是必需的;弹性正畸装置不需要足够的牙齿固位,并且对牙齿表面的干预最小。
