Hypodontia or anodontia presents with socio-psychological problems due to impaired aesthetics, masticatory defficiency and underdeveloped jawbone mimicking marked residual bone resorption seen in ectodermal dysplasia patients.
To describe a useful impression technique which enhances retention and support of a cheap, functional removable dentures.
An 18-year old male presented with complaints of poor dental appearance. Full medical and dental histories well-taken before a dental assessment was made.
The patient was born to apparently normal parents. His main concern was poor dental appearance owing to failure of his teeth to erupt. He had adopted violent and evasive behaviours to overcome embarrassment in his early childhood. However, as he grew older, these behaviours could not compensate for the psycho-social challenges in his adulthood due to embarrassing appearance. The lips were everted with a prognanthic lower jaw bone. The lower edentulous ridge was poorly formed and small with unemployed mandibular ridge, but the first molars were present. The patient was rehabilitated with relatively inexpensive conventional removable acrylic partial dentures fabricated using selective impression technique, to enhance support, stability and retention for adequate function.
These well fitting, functional dentures improved the appearance, psychological and social behaviour of the patient while unacceptable social behaviours were prevented.
牙缺失或无牙症会因美观受损、咀嚼功能不足以及颌骨发育不全而导致社会心理问题，这与外胚层发育不良患者中明显的残余骨吸收相似。
描述一种有助于增强廉价功能性可摘义齿固位和支持的印模技术。
一名18岁男性因牙齿外观不佳前来就诊。在进行牙科评估之前，详细记录了完整的病史和牙科病史。
患者父母外表正常。他主要担心的是由于牙齿未萌出导致的牙齿外观不佳。他在幼儿期采取了暴力和回避行为来克服尴尬。然而，随着年龄的增长，由于外表尴尬，这些行为无法弥补他成年后的心理社会挑战。嘴唇外翻，下颌骨前突。下颌无牙嵴形态不佳且较小，下颌嵴未利用，但第一磨牙存在。使用选择性印模技术制作相对便宜的传统可摘丙烯酸局部义齿对患者进行修复，以增强支持、稳定性和固位，实现充分功能。
这些贴合良好、功能正常的义齿改善了患者的外观、心理和社会行为，同时防止了不可接受的社会行为。
