The Preliminary Report on Evaluation of Interproximal Papilla Defects of Maxillary Central Incisors 评价上颌中切牙龈乳头缺陷的初步报告
Most food impaction happened in the interproximal of molars. The impaction types were mainly hybrid and vertical impaction, and only 9.7% was horizontal impaction. 嵌塞部位以磨牙间隙为主,嵌塞类型以混合型和垂直型嵌塞为主,水平型所占比例为9.7%。
Objective: To evaluate the clinical effect of three kinds of dental filling materials for interproximal caries of permanent molars. 目的:评价用银汞合金、可乐丽菲露AP-X复合树脂及Beautifil氟化玻璃聚合体对恒磨牙邻面龋进行充填治疗的临床效果。
Results The interproximal gingival papillae adjacent to all transplanted teeth were normal or slightly hyperplastic. 结果自体移植牙牙靓无明显增生或退缩。
CONCLUSION: In complete dentition, the occlusal strength is distributed through the contact area between interproximal teeth, therefore, the stress value of crown is low. 结论:完整牙列受力时,牙合力通过牙之间的接触区传递分散,牙冠的应力值很小。
PURPOSE: To evaluate the stress distribution of crowns under mastication from the biomechanical respect, and observe the physical effects on different teeth through the interproximal contacts. 目的:从生物力学角度对牙间的邻面接触关系的生理作用进行观察,探讨在咀嚼受力时牙冠组织的应力分布状况。
Objective: To investigate the multiple factors that affect the dental interproximal system. 目的:探讨影响牙邻面接触关系的多种因素及其互联关系。
Clinical evaluation on restoration of permanent molars with interproximal caries 恒磨牙邻面龋充填治疗的疗效评价
In Group B, interproximal enamel reduction was made, but no polishing and remineralize treatment. B组:釉质去除组,邻面进行釉质的去除,未进行抛光和再矿化处理。
If the surfaces are polished and treated with fluoride foam, the caries risk of enamel after orthodontic interproximal enamel reduction is the similar as that without enamel reduction. 进行邻面去釉后,经过抛光及氟化泡沫再矿化处理的牙齿去釉面的龋患风险与去釉前的牙齿相当。
