Brief Summary

Introduction: The investigators aimed to evaluate the effectiveness of non-extraction orthodontic treatment for Angle class I malocclusion.

Conditions

Angle Class I

Keywords

Non-extraction; orthodontics treatment; Angle class I malocclusion

Outcome Measures

Primary Outcomes (1)

• We aimed to evaluate the effectiveness of non-extraction orthodontic treatment for Angle class I malocclusion.

  Cephalometric radiographs, and extraoral and intraoral photographs, and cast impressions were collected before and after intervention. The weighted PAR Index (Peer Assessment Rating) employed to determine outcome of orthodontic treatment

  Cephalometric radiographs, and extraoral and intraoral photographs, cast impressions and PAR Index (Peer Assessment Rating) were collected before and after intervention through study completion, an average of 2 years

Study Arms (1)

Cephalometric radiographs and cast impressions were collected before and after intervention.

OTHER

Interventions

Non-extraction Orthodontic Treatment of Angle Class I Malocclusion OTHER

Cephalometric radiographs, and extraoral and intraoral photographs, and cast impressions were collected before and after intervention. The weighted PAR Index (Peer Assessment Rating) employed to determine outcome of orthodontic treatment. Also the following soft tissue and bone indexes were assessed before and after intervention

Model Details: Cephalometric radiographs, and extraoral and intraoral photographs, and cast impressions were collected before and after intervention. The weighted PAR Index (Peer Assessment Rating) employed to determine outcome of orthodontic treatment. Also the following soft tissue and bone indexes were assessed before and after intervention, SNA, SNB, ANB, SN\_GoGn, SN\_Occplane, U1\_NAmm, U1\_NA, L1\_NBmm, L1\_NB, U1\_L1, U1\_Mp, Ls\_E, Li\_E, and Nasolabial\_angle. Intervention was MBT (MBT System, 3M Unitek, USA) non-extraction fixed orthodontic treatment. One experienced researcher analyzed and interpreted all of the cephalometric images used in the study using the WedCeph (https://webceph.com/). Data were analyzed by linear regression and T-Test statistical test using R software version 4.3.0 (R Foundation for Statistical Computing, Vienna, Austria) by a blinded statistician.
