Vertical overlap (overbite) and horizontal overlap (overjet).

Although there is insufficient evidence to determine which retainer is more effective in studies comparing Essix and Hawley retainers (5, 6), the overjet, overbite, maxillary and mandibular intercanine widths, intermolar widths, arch lengths, and irregularity indexes were evaluated with regard to clinical effectiveness.

However its effect in reducing overjet in class-II patients has been documented to have exceptional social impact in increasing patients confidence as stated in a study done by O'Brien et al., 2003.
During the examination for recording overbite and overjet, it was found that the OSA patients did not have deep overbite or severe overjet as was reported by other studies.
The authors suggested that the main advantage of BSSO-TMAO technique over BSSO-genioplasty combination is the relatively decreased advancement required, because the surgical movement is limited to the extent dictated by the maxilla-mandibular skeletal relationship, as opposed to the dental relationship (dental overjet).
For measurements of overjet and overbite, a standard ruler was used, and measurements were obtained to the nearest 0.1mm.
The variables that were evaluated in the calibration process were the following: incisor alignment, Angle's classification of malocclusion, posterior and anterior crossbite, overjet, overbite, anterior open bite, and maxillary midline diastema.
Significant increases in ANB, MP-PP, SN-MP angles, ANS-Me, HR[perpendicular to]PNS, VR[perpendicular to]A, PP[perpendicular to]U1i measurements and overjet and significant decreases in SNB, U1-SN angles, and VR[perpendicular to]B, VR[perpendicular to]L1i measurements and overbite were found in the RME group (group 2) during the expansion period (T1-T0) (p<0.0083).
The etiology of maxillary incisor trauma (MIT) includes oral predisposing factors (7), which have been identified as increased overjet, incompetence lip coverage of the upper anterior teeth and Class II division 1 malocclusion (9-11).
El diagnostico de los sujetos con DF-III se realizo clinicamente, confirmando una retrusion maxilar y prognatismo mandibular y a nivel dentario identificando un overjet igual o menor a cero y una relacion molar de clase III de Angle.
Facial analysis observed the convex profile, straight nasolabial angle, short mentocervical line and occlusion analysis the molar and canines in Class II, equal to or higher than the half of a cusp, and overjet equal to or greater than 5mm.
