The author emphasizes that the overbite is a component of a lot of malocclusions, but he thinks that it doesn't exist standard values of overbite for all the people. The value would adapt to the patient's feature. He analyses dental movements, for the overbite correction, and skeletal features that allow them or not. The author suggests an overbite classification that depends on functional noise, skeletal noise, clinical noise and aesthetics noise. At least, it's underlined that this malocclusion must ever be overcorrected, and it's taken in consideration that differences between physiologic recovery and relapse.
