Assessment Of Orthodontic Treatment Complexity, Outcome And Objective Treatment Need

Objective:To assess the orthodontic treatment complexity,degree of improvement and objective treatment need of patients treated in Stomatology Hospital of Shandong University by using the index of complexity,outcome and need(ICON).Methods:1.114 cases were randomly selected from the Stomatology Hospital of Shandong University.The range for the pre-treatment age was 16 to 43years.(90 females,24 males) The ICON was used to assess the pre-treatment study models for orthodontic treatment need and complexity for the cases.2.20 pairs pre-and post-treatment study models were randomly selected from the Stomatology Hospital of Shandong University.The range for the pre-treatment age was 13 to 40years.(13 females,7 males) The ICON was used to assess the pre-and post-treatment study models for orthodontic treatment outcome and treatment improvement.Result:1.In treatment complexity,there were 13(11.4%) cases was easy,26(22.8%) cases was mild,21(18.4%) cases was moderate,29(25.4%) cases was difficult,25(22.0%) cases was very difficult in 114cases.2.There were 33(29.0%) cases did not need treatment,while 81(71.0%) cases needed treatment in 114cases.3.In treatment outcome,there were 15(75.0%) cases had "greatly improved", 4(20.0%) cases had "substantially improved",1(5%) case had "moderately improved", while there was no patient had "minimally improved" and "not improved or worse".Conclusion:1.Most patients were difficult to orthodontic treatment.2.There were partly over-treatment patients.3.The orthodontic treatment outcome of most patients were satisfied.
