Design outcomes

Primary

MeasureTime frame
Validity of the IBO Orthodontic Index in assessing The severity degree of difficulty of malocclusion before treatment The treatment outcome improvement after orthodontic care across different types of malocclusion Class I II and IIITimepoint: Pre-Treatment (Baseline): Collection of initial patient records before starting orthodontic treatment. Includes: photographs, study models, and lateral cephalographs. Purpose: To assess the initial severity of malocclusion using the IBO Orthodontic Index. Post-Treatment (Final Assessment): Collection of records after completion of orthodontic treatment. Includes: final photographs, study models, and lateral cephalographs. Purpose: To assess the treatment outcome and degree of improvement using the IBO Index. Reliability Testing (For Scoring Consistency): Initial Scoring: 15 sets of models scored by both examiners. Re-scoring after 1 month: Same 15 sets re-evaluated to assess intra-examiner reliability.

Secondary

MeasureTime frame
Comparison of treatment complexity among Class I, II, and III malocclusion groups using pre-treatment IBO Index scores. Comparison of treatment outcomes among Class I, II, and III malocclusion groups using the percentage improvement from pre- to post-treatment IBO Index scores. Inter-examiner and intra-examiner reliability of IBO Index scoring using statistical methods (Bland-Altman plot and Intraclass Correlation Coefficient). Feasibility and practicality of using the IBO Index in routine clinical settings.Timepoint: Pre-Treatment (Baseline): Collection of initial patient records before starting orthodontic treatment.
