Some angular and linear measurements were made and skeletal ages were determined on the first and second films. The differences of the measurements were calculated by subtracting the first year measurements from the second year measurements. The interrelationships between the cephalometric measurement differences and the skeletal age, height, and weight differences were investigated by means of correlation analysis. Furthermore, the correlation coefficients were verified by t test. Most of the correlation coefficients were found to be statistically unsignificant, while a few statistically significant.</p>","PeriodicalId":77814,"journal":{"name":"Turk ortodonti dergisi : Ortodonti Derneg'nin resmi yayin organidir = Turkish journal of orthodontics","volume":"2 1","pages":"37-46"},"PeriodicalIF":0.0,"publicationDate":"1989-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13632618","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}
{"title":"[Classification of functional orthopaedic appliances in our opinions].","authors":"E Erdoğan, E Erdogăn","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Appliances which are used for functional orthopedic therapy, is called as functional orthopedic appliances. So far, it has been constructed many appliances for functional treatment. But among these appliances, only activators were classified by STOCKFISH, H. in terms of construction specialty at his laboratory. Whole functional appliances were arranged by Gürsoy, N. and Perkün, F. according to the organ which their functional balance pas spoiled by these appliances (according to the soft and hard tissue of organs) and Proffit, W. classified functional appliances in terms of the tissues which support them. In fact, these appliances should be classified according to the force they apply and their effect mechanism. Classification of functional appliance according to the force they apply: I- Pure functional appliance, II-Mechano-functional appliance. I- Pure functional appliance: A) Activators, B) Regulators. II-Mechano-functional appliance: A) Fixed, B) Removable. Classification of functional appliances according to the their effect mechanism: I- Activators, II- Regulators. I- Activators are separated two: A) Pure functional, B) Mechano-functional, and these are divided into sub-divisions. II- Regulators are separated three: A) Oral screens, B) Lip bumpers, C) Frankel appliance (4 type). We believe that, every two classification which were shown before at two charts, will be useful to our colleagues.</p>","PeriodicalId":77814,"journal":{"name":"Turk ortodonti dergisi : Ortodonti Derneg'nin resmi yayin organidir = Turkish journal of orthodontics","volume":"2 1","pages":"47-50"},"PeriodicalIF":0.0,"publicationDate":"1989-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13632619","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}
