title: A new yardstick for rating dental arch relationship in patients with complete bilateral cleft lip and palate.
abstract: OBJECTIVE
  To develop yardsticks for assessment of dental arch relationship in young individuals with repaired complete bilateral cleft lip and palate appropriate to different stages of dental development.
  
  
  METHODS
  Eleven cleft team orthodontists from five countries worked on the projects for 4 days. A total of 776 sets of standardized plaster models from 411 patients with operated complete bilateral cleft lip and palate were available for the exercise.
  
  
  METHODS
  The interexaminer reliability was calculated using weighted kappa statistics.
  
  
  RESULTS
  The interrater weighted kappa scores were between .74 and .92, which is in the "good" to "very good" categories.
  
  
  CONCLUSIONS
  Three bilateral cleft lip and palate yardsticks for different developmental stages of the dentition were made: one for the deciduous dentition (6-year-olds' yardstick), one for early mixed dentition (9-year-olds' yardstick), and one for early permanent dentition (12-year-olds' yardstick).
