Man-Suk Baek and others evaluated long-term stability of anterior open bite by intrusion of maxillary posterior teeth. Their results showed that the molars were intruded by 2.39 mm during treatment and relapsed back by 0.45 mm or 22.8%. The incisal overbite increased by 5.56 mm during treatment and relapsed back by 1.20 mm or 17%.

The Index of Orthodontic Treatment Need rates overjet highly on its weighting system, second behind missing teeth. It then grades severity of overjet as: [12] Grade 3, Borderline need for treatment = increased overjet 3.5 mm (0.14 in) < 6 mm (0.24 in) Grade 4, Need for treatment = increased overjet 6 mm (0.24 in) < 9 mm (0.35 in) Grade 5, Need ...
The influence of the contacting surfaces of the mandibular and maxillary incisors on mandibular movements [12] is characterised by the overbite and overjet of the maxillary incisors. In restorative treatment, it is possible to manipulate and design anterior guidance systems that is in harmony with the masticatory system.
Positive overjet, positive overbite, distal molar relationship and posterior crossbite with maxillary teeth buccal to mandibular teeth.
