Food impaction is a severe clinical trouble that bothers most people especially middle aged and old people. It is reported that the rate of food impaction is 92.2%. The incidence of 40-59 years old is 98.9%. It is a disease of high prevalence in population. It has influenced people's social intercourse and everyday life because it may cause halitosis, gingivalitis, periodontitis, gingival abscess, alveolar bone absorption, root caries, eventually lead to severe results from teeth loose to deletion and so on. Several reasons are involved with food impaction such as gingival recession, periodontal disease, caries, age, excessive attrition, etc. Food impaction can be divided into two kinds: vertical and horizontal food impaction. At present, there are some clinical methods such as crown or dental filling for vertical one, but horizontal food impaction is still difficult to deal with. Though some methods are being adopted like making crowns and removable obstructers, the problems have never been settled effectively for the injury to teeth and inconvenience of these treatments. Here we put forward a hypothesis that periodontal tissues can regenerate much the same as normal situation by way of using drug to induce gingiva hyperplasia initiatively and implanting scaffolds. Then horizontal food impaction will be cured when the interproximal clearance is filled with periodontal tissues. It will bring the patient hope.
食物嵌塞是一种严重的临床问题，困扰着大多数人，尤其是中老年人。据报道，食物嵌塞的发生率为 92.2%。40-59 岁人群的发病率为 98.9%。它是一种高发疾病，影响了人们的社交和日常生活，因为它可能导致口臭、牙龈炎、牙周炎、牙龈脓肿、牙槽骨吸收、根龋，最终导致牙齿松动甚至缺失等严重后果。食物嵌塞的原因有牙龈退缩、牙周病、龋齿、年龄、过度磨损等。食物嵌塞可分为垂直型和水平型两种。目前，对于垂直型食物嵌塞，有一些临床方法，如冠或牙填充，但水平型食物嵌塞仍然难以处理。虽然有人采用制作冠和可移动阻塞器等方法，但由于这些治疗方法对牙齿的损伤和不便，问题从未得到有效解决。我们提出了一个假设，即通过药物主动诱导牙龈增生并植入支架，可以使牙周组织再生，恢复到接近正常的状态。当牙周组织填满牙间隙时，水平型食物嵌塞就会得到治愈。这将给患者带来希望。
