2018

Scholarcy highlights

  • Deep bite occurs with a prevalence of about 15–20% in the US population
  • This review investigated the role of various parameters and treatments strategies on stability of deep bite correction
  • Inclusion criteria – clinical studies reporting on the stability of deep bite correction Databases searched – PubMed, Web of Science, Embase, Cochrane Dates searched – Jan 1966 to June 2012 Other sources of evidence – hand searching of reference lists Language restrictions – none
  • Three additional studies were identified by hand searching, for a total of 26
  • Weighted averages for overbite and follow‐up time were calculated for each group: Class I, Class II Div 1, and Class II Div 2, based on the sample size
  • The randomized controlled trial stated that only 10% of deep bite patients relapsed to more than 50% overbite long term
  • The systematic review reports on treatment and stability of Class II Div 2 malocclusion, and concludes that the existing evidence is at high risk for bias
