The advantage of this spring is that in large areas the pseudoelastic part of the spring transfers constant moments and forces to the molars. In addition, the steel part makes it possible to simply and easily adjust and fasten alpha-bends. Because of the relatively small uprighting moments of 10 up a maximum of 25 Nmm such an uptighting spring can also be applied without any modifications in cases in which the molars are tipped up to 50 degrees. Going beyond this our study determined that it is possible to exert intrusive forces of 0.4 N over the entire uprighting area by bending-in an 45 degrees alpha-bend. From a 15 degrees tipping on up the uprighting moments applied to molars remain relatively constant and they are only dependent on the bent alpha-activation. An uprighting by intrusive force on the molars can also be achieved through an alpha-activation of 0 degree (90 degrees + 40 degrees), when the vertical length of the pegs is enlarged. An on average 1.43 mm per month root mesialization of the uprighting spring with the Memory Maker, should such for whatever reason be considered desirable, take place only in the final stage. In almost every case of molar uprighting it is possible to fasten a figure eight ligature from the molar to the cross tube. The uprighting spring presented here combined with a cross tube proves to be an effective method for achieving a fast and trouble free uprighting of molars.</p>","PeriodicalId":77135,"journal":{"name":"Fortschritte der Kieferorthopadie","volume":"56 6","pages":"296-308"},"PeriodicalIF":0.0,"publicationDate":"1995-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02173156","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19633177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed distinctive differences between Angle class II/1 and II/2. The sagittal correction in class II/1 was a result of the reduction of the SNA angle, the mandibular protrusion, and the retrusion of the upper incisors. The face high index was normalized. No labial inclination of the lower incisors was registered. In the Angle class II/2 cases the SNA angle was unchanged. The sagittal correction was brought about exclusively through mandibular translation. The deep bite and the retrusion of the upper incisors weren't markedly improved.

It finds application as an individual appliance, in combination with removable appliances, and in conjunction with the fixed appliance technique. The major advantage of the face bow is that during a check-up visit, because it is already in place, it presents itself as a proven means for the treatment of asymmetries by adding a hinge on the side not to be distalized and by shortening the external arm on the same side. It is not necessary to employ a new, special face bow or even to change the orthodontic bands. In addition, in the case of an intermaxillary midline correction, no anchorage loss occurs. In the case of more extensive molar rotations, a pretreatment with a palatal archwire is recommended to rotate the molars. Because in 4% of the patients a cross bite or a cross bite tendency arises on the side distally treated, at the beginning of treatment the use of bands with attachments for palatal archwires should be considered. Relatively sizable distal forces in the range of 2:1 to 4:1 are exerted on the molar. This should be taken into account when selecting the forces of the external arm. It is recommended to apply on each of both sides a distal force of no more than 4 to 5 N. Decoupling of forces and movements through the internal hinge makes it possible for the practitioners to check the asymmetrical effect of the face bow by pulling out carefully the lingual archwire from the right or left tube. As long as the hinge still folds down, when the face bow is applied, the geometrics of the face bow should be altered. The following procedures can be recommended: 1. Further shortening of the already shortened arm; 2. outward bending of the long external arm; 3. use of an additional stop tube at the lingual archwire on the side that must be distalized. During the use of related low-pulls, the molars are subjected to diverse forces as a result of preferred sleeping positions, head bearings, and extensive friction, To avoid these non-calculable asymmetries, it is recommended to use gliding low-pulls. Because of the excellent results achieved throughout the use of the asymmetrical headgear with the lingual archwire, it can be recommended that it become a standard appliance in clinical practice.</p>","PeriodicalId":77135,"journal":{"name":"Fortschritte der Kieferorthopadie","volume":"56 6","pages":"327-38"},"PeriodicalIF":0.0,"publicationDate":"1995-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02173159","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19631793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
