Background: The insertion of removable or fixed space maintainers is a common treatment in cases of premature loss of a primary molar in pediatric dentistry. This is rarely evident. It is interesting to get data about the benefit of using space maintainers and in the case of an positive effect, to evaluate which type is more effective, the removable or the fixed maintainer. Materials and methods: In a retrospective study a total of 352 children were examined, who got treated with two different types of space maintainers, between 01.01.2016 and 30.06.2018. The function of the space maintainer and the compliance of the children were evaluated every 5 months. It was also evaluated, if a space maintainer had prevented a future orthodontic treatment. Results: From the total of 352 children, who matched the inclusion critera, 172 (48.9 %) were treated with an removable and 180 children (51.1 %) with an fixed space maintainer. The cohort consisted of 200 boys (56.8 %) and 152 girls (43.2 %). The average age was 6,5 years at the time of extraction (sd 1.7). The average time period between the extraction and the insertion of the space maintainer was 25 days (sd 74.2). After the evaluation period of 20 months 52 children (30.2 %) showed a functional removable space maintainer with a good compliance. The fixed space maintainers were mostly inserted to keep the space of the first primary molar of children with an average age of 6 years (66 %). The removable space maintainers were used for children with an average age of 7 years at the time of the extraction. They were usually used to keep the space for the second primary molar while the first permanent molar was already erupted. In comparison to this, 25 (13.9 %) functional fixed space maintainers were evaluated in the cohort. Statistical significant findings were evaluated after 12, 14 and 16 months in comparison of the function of the two types of space maintainers (Wilcoxon-Mann-Whitney-Test, p-values: 0.01, 0.00 and 0.00). Statistically significant more of the children, who were treated with a removable space maintainer and not treated with an fixed appliance, received an active orthodontic treatment afterwards during the evaluating period (Chi-Quadrat-Test n. Pearson, p-value: 0.00). Conclusion: By means of the present monitoring study from a German paediatric dental practice can be concluded, that removable space maintainers are more functional during a long time period in comparison to fixed space maintainers. The “band and loop” space maintainers were used for younger children (often treated under general anaesthesia) to keep the space for the first primary molar. But in a long time period the failure rate was higher (complete loss, gingival problems, uncooperation of the child), so that the space maintainer could not be recemented, that finally causes an untreated gap in the primary dentition. The removable space maintainers were used for older children to keep the space for the second primary molar
背景:插入可移动的或固定的空间维持器是一种常见的治疗情况下过早丢失的第一磨牙在儿科牙科。这一点很少明显。获得关于使用空间维护器的好处的数据，以及在产生积极效果的情况下，评估可移动维护器和固定维护器哪种类型更有效，这是很有趣的。材料与方法:在2016年1月1日至2018年6月30日期间，对352名儿童进行回顾性研究，采用两种不同类型的空间保持器进行治疗。每5个月对空间维护器的功能和儿童的依从性进行评估。还评估了间隙维持器是否阻止了未来的正畸治疗。结果:352例符合纳入标准的患儿中，有172例(48.9%)采用可移动的间隙维持器，180例(51.1%)采用固定式间隙维持器。该队列包括200名男孩(56.8%)和152名女孩(43.2%)。拔牙时的平均年龄为6.5岁(sd 1.7)。从取出到插入空间维持器的平均时间为25天(sd 74.2)。经过20个月的评估期，52例患儿(30.2%)显示出功能可移动空间维持器，依从性良好。固定空间维持器主要用于保持第一磨牙空间，平均年龄为6岁(66%)。可移动空间维持器用于拔牙时平均年龄为7岁的儿童。当第一恒磨牙已经长出时，它们通常用来为第二乳牙保留空间。与此相比，在队列中评估了25例(13.9%)功能性固定空间维持器。两种空间维持器在12、14、16个月后的功能比较有统计学意义(Wilcoxon-Mann-Whitney-Test, p值分别为0.01、0.00、0.00)。在评估期间，使用可移动间隙维持器治疗而不使用固定矫治器治疗的儿童接受积极正畸治疗的比例有统计学意义(χ - quadratt检验n. Pearson, p值:0.00)。结论:通过目前德国儿科牙科实践的监测研究可以得出结论，与固定空间保持器相比，可移动空间保持器在长时间内功能更强。“带环”空间维持器用于年幼的儿童(通常在全身麻醉下治疗)，以保持第一初级磨牙的空间。但长期使用失败率较高(完全丢失，牙龈问题，儿童不配合)，使得间隙保持器无法重新修复，最终导致原生牙列未治疗间隙。可移动空间维持器用于年龄较大的儿童，当第一恒磨牙已经出牙时，用于保持第二初级磨牙的空间。经过12个月、18个月和20个月的时间后，其中三分之一仍在使用或可以很容易地进行改装。研究背景:Herausnehmbare und festsitzende l<s:1> ckenhalter werden häufig beeiner vorzeitigen提取eines Milchzahns在der Kinderzahnheilkunde eingesetzt。Die evidence ist spärlich。他是一名德国学者，他是一名德国学者，他是一名德国学者，他是一名德国学者，他是一名德国学者，他是一名德国学者。材料与方法[j] .材料与方法[j] .材料与方法[j] .材料与方法[j] .材料与方法[j] .材料与方法[j] .材料与方法[j] .材料与方法[j] .材料与方法。珠宝首饰5种熔模分析、熔模分析、熔模分析、熔模分析、熔模分析和熔模分析。in weiteren Sinne wurde evaluiert, inwiewedas Inserieren eines lckenhalters eine spätere kieferorthopädische干预verhinderte。Ergebnisse Von den 352 Kindern, die die einschlusskriteren erfellten, erhielten 172 Kinder (48,9%) einen herausnehmbaren和180 (51,1%)einen festsitzenden l<s:1> ckenhalter。underden Kindern waren 200 Jungen(56.8%)和152 Mädchen(43.2%)。引用本文:刘建军。提取滞后问题的研究进展[j] .农业科学(英文版)。引用本文:1 .

Background: Treatment of carious deciduous teeth is still underrepresented in Germany. Recent numbers of epidemiological investigations show that 50 % of carious milk teeth are actually treated. The present review elucidates and appraises possibilities of invasive restorative measures in deciduous teeth. Materials and Methods: Considering both literature review and own data, restorative concepts and adequate materials are introduced. Results: Modern adhesive techniques and materials allow for minimally invasive therapy in the first dentition. Defensive excavation is sufficient for effective restorative treatment, however, margins and enamel-dentin junctions have to be excavated consequently in order to get appropriate marginal seal. Due to positive clinical results, adhesively bonded resin composites are favorable for both anterior and posterior deciduous teeth. So-called bulk-fil resin composites are assumed to play an important role in the future. Dependent on both the child’s compliance and the size of the defect, conventional or resin-modified glass ionomer cements as well as tailored crowns can be also applied. Conclusion: Due to several valid treatment options, deciduous teeth can be safely restored and there is no need for leaving them untreated. Hintergrund Die Sanierung von kariösen Milchzähnen spielt in der Bundesrepublik nach wie vor eine untergeordnete Rolle. Aktuelle Zahlen der epidemiologischen Untersuchungen zeigen, dass gerade etwa 50 % der Milchzahnkaries versorgt werden. Die vorliegende Übersichtsarbeit soll daher die Möglichkeiten der restaurativen invasiven Versorgung von Milchzähnen vorstellen und bewerten. Material und Methode Im Rahmen einer Literaturrecherche und anhand von eigenen Daten wurden Füllungskonzepte und -materialien für das Milchgebiss bewertet. Ergebnisse Aktuelle adhäsive Techniken und Materialien ermöglichen eine defektorientierte und minimalinvasive Therapie in der 1. Dentition. Für die Füllungstherapie ist eine schonende Kariesexkavation ausreichend. Allerdings müssen die Füllungsränder und die Schmelz-Dentin-Grenze gut exkaviert werden, um einen dichten Randschluss zu gewährleisten. Aufgrund der positiven klinischen Ergebnisse sind adhäsiv applizierte Komposite für die Füllungstherapie im Front- und Seitenzahnbereich des Milchgebisses das Mittel der Wahl. Sogenannte Bulk-Fil-Komposite könnten künftig auch im Milchgebiss eine bedeutende Rolle in der Therapie spielen. Je nach Mitarbeit der Kinder und der Defektgröße können Milchzähne mit konventionellen bzw. lichthärtenden Glasionomerzementen oder konfektionierten Kronen versorgt werden. Fazit Aufgrund des vielseitigen Angebotes in der Füllungstherapie müssen Milchzähne heutzutage nicht mehr unbehandelt bleiben.
背景:在德国，乳牙龋齿的治疗仍然不足。最近的流行病学调查数字表明，50%的乳牙实际上得到了治疗。本文综述了有创性乳牙修复方法的可行性。材料和方法:结合文献回顾和自身资料，介绍修复概念和适当的材料。结果:现代粘接技术和材料使第一牙列的微创治疗成为可能。对于有效的修复治疗，防御性挖掘是足够的，然而，为了获得适当的边缘密封，必须挖掘边缘和牙釉质-牙本质连接。粘连树脂复合材料对前乳牙和后乳牙均有良好的临床效果。所谓的大块填充树脂复合材料被认为将在未来发挥重要作用。根据儿童的顺应性和缺损的大小，也可以使用传统的或树脂改性的玻璃离子水门汀以及定制的冠。结论:由于有几种有效的治疗方法，乳牙可以安全修复，无需对其进行治疗。在德国联邦共和国(Bundesrepublik)的研究中，研究人员发现了一种新的研究方法。流行病学家Aktuelle Zahlen表示，德国有50%的人患有这种疾病。Die vorliegende Übersichtsarbeit solher Die Möglichkeiten der restaurativen invasiven Versorgung von Milchzähnen vorstellen und between。材料与方法[m] .文献研究与分析:文献研究与分析:文献研究与分析:文献研究与分析:文献研究与分析:文献研究与分析:文献研究与分析:文献研究与分析:文献研究与分析:文献研究与研究。Ergebnisse Aktuelle adhäsive Techniken and Materialien ermöglichen edektoriente和微创治疗在der中的应用[j]。生齿。肺治疗学:肺死亡治疗学。过敏原 ssen die Füllungsränder and die Schmelz-Dentin-Grenze gut exkaviert werden, um einen dichten Randschluss zu gewährleisten。1 .在德国，研究人员正积极地研究klinischen Ergebnisse和adhäsiv应用于复合材料和材料治疗-与德国医学研究中心和德国医学研究中心合作。Sogenannte bulk - fil - composite könnten knftitich - in Milchgebiss - bedetende Rolle in der Therapie spielen。jeach Mitarbeit der Kinder und under Defektgröße können Milchzähne mit conventionellen bzw。lichthärtenden glass - onomerzementen der konfektionierten Kronen verorgt werden。[1] [1] [1] [1] [1] [1] [1] [1] [1] [1] [1] [1] [1] [1] [1] [1]
