The purpose of the present study was to cephalometrically evaluate the bite plane effect associated with deep overbite correction in cases treated exclusively with the Ormco-Kurz™ lingual orthodontic appliance, and to evaluate whether differences existed between dolichofacial and brachyfacial facial types. Variables involved in the bite plane effect; incisor intrusion and proclination, as well as molar extrusion and mandibular rotation were measured. Fifty-nine cases were evaluated by means of computer digitized tracings of pretreatment and posttreatment lateral cephalograms. Mandibular incisor proclination of 4.5 degrees, mandibular incisor intrusion of 2.3 mm, lower anterior facial height opening of 1.3 mm and maxillary incisor intrusion of 1.2 mm all contributed to correction of the deep anterior overbite. No significant differences existed between dolichofacial and brachyfacial facial types for any of the variables measured.
Key words: Lingual orthodontics, deep overbite, bite plane effect, intrusion.
