“…A retrospective study by Luther et al 9 highlighted that the duration of the preoperative phase of orthodontics may be influenced by the orthodontist; in the present study, all patients were treated or supervised by qualified specialists who had attained equivalent levels of training. Previous research demonstrated that age and gender have little impact on treatment duration.…”

“…Previous research demonstrated that age and gender have little impact on treatment duration. 9 Therefore, these items were omitted from the statistical analysis. Because extraction-based treatment is known to extend the treatment duration, 11 it was included as a potential confounding variable.…”

“…The peer assessment rating (PAR) provides a valid and reproducible [4][5][6] objective assessment of the success of orthodontic treatment in isolation and has been applied to assess the quality of occlusal outcome following combined treatment. [7][8][9][10] The duration of combined treatment has typically been estimated at 2 years or longer. [7][8][9] Indeed, O'Brien et al 7 in a prospective investigation highlighted that mean treatment duration may approach 3 years, with a mean time of 33 months reported.…”

Objective: To analyze the effects of single-jaw surgery (mandible or maxilla only) vs bimaxillary surgery on final peer assessment rating (PAR) score outcome and overall treatment duration. Materials and Methods: Treatment records of 63 consecutively treated orthognathic patients were assessed; 41 underwent bimaxillary procedures, and the remainder single-jaw procedures. All treatment was undertaken at Kent and Canterbury Hospital in the United Kingdom. Demographic characteristics and clinical parameters, including treatment duration, number of visits required, initial and final PAR scores, and number of extractions undertaken, were recorded. Results: The mean treatment time was 30.6 months; treatment time was shortest in the maxillary procedure only group. The mean reduction in percentage PAR score was 77%, with an average final score of 9. Linear regression analysis confirmed that procedure type had no influence on final PAR score (P 5 .62) or on overall treatment duration after adjustment for extractions and initial PAR score as confounders (P 5 .47). Conclusions: No significant difference was noted in treatment duration or in occlusal outcome between single-and double-jaw surgeries. (Angle Orthod. 2011;81:983-987.)
