Conclusion Costs for repeated treatment of post-orthodontic enamel damages produced by conventional vestibular fixed appliances may easily exceed the initially higher costs associated with lingual orthodontic treatment .
Judged economically in the long term , lingual MB Tx may be considered as a more cost-effective solution for a correction of malocclusion
Background Post-orthodontic white-spot lesions ( WSL ) in esthetically relevant incisor and canine areas impair dentofacial esthetics , and preventive dentistry treatment is definitely required in case of enamel cavitations .
The incidence of lingual post-orthodontic WSL and cavitation following lingual MB treatment has been reported to be distinctively decreased compared to labial MB treatment .
Moreover , lingual WSL do not impair dentofacial esthetics .
It was the objective of this study to calculate consequential costs of preventive dental care necessary to recover labial or lingual post-orthodontic cavitations as well as esthetically relevant WSL following either labial or lingual MB interventions .
Lingual orthodontic treatment duration: performance of two different completely customized multi-bracket appliances (Incognito and WIN) in groups with different treatment complexities
Introduction The occurrence of side-effects of fixed orthodontic therapy , such as white-spot lesions and root resorption , are known to be significantly more frequent with increasing duration of treatment . Multi-bracket treatment should be as short as possible , in order to minimize the risks of collateral damage to teeth . The aim of this non-r and omized clinical trial was to compare treatment duration with each of two types of customized lingual orthodontic appliances ( Incognito , 3 M-Unitek ; WIN , DW LingualSystems ) , taking into account treatment complexity . The null-hypothesis was that there would be no significant difference in active orthodontic treatment duration between them . Methods Of 402 potentially eligible participants , a population sample of n = 376 subjects ( nIncognito = 220 ; nWIN = 156 ; m/f 172/204 ; mean age ± SD 17.3 ± 7.7Y ) treated in one orthodontic center ( Bad Essen , Germany ) with completely customized lingual appliances in upper and lower permanent dental arches was recruited with the inclusion criterion of initiated and completed lingual multi-bracket treatment within the assessment period of April 1st 2010 – Nov 30 , 2013 , and the exclusion criterion of less than 24 bracketed teeth . We used four-factorial ANOVA to assess the impact of the following factors : initial degree of severity of malocclusion ( mild to moderate , S1 ; severe , S2 ) , appliance type ( Incognito ; WIN ) , sex , and age group ( < = 16 ; > 16 Y ) on the duration of lingual multi-bracket treatment . Results Overall , mean treatment duration was 21.7 ( SD 7.2 ) months , which was significantly shorter for WIN for both sub-groups of treatment complexity ( S1 : 17.96 mo ; S2 : 20.49 mo ) compared to Incognito ( S1 : 22.7 mo ; S2 : 29.79 mo ) . ANOVA revealed a significant influence of the main effects ‘ appliance type ’ , and ‘ severity ’ , independent of each other . Therefore , the null-hypothesis was rejected . Conclusion In terms of treatment duration , the WIN appliance performed significantly better than the Incognito appliance . Consequently , subjects treated with the WIN appliance are expected to be exposed to lower risks of the typical side-effects associated with longer multi-bracket treatment duration s , such as root resorption and enamel decalcification
Conclusion Costs for repeated treatment of post-orthodontic enamel damages produced by conventional vestibular fixed appliances may easily exceed the initially higher costs associated with lingual orthodontic treatment .
