Class II, Division I malocclusion has been described as the most frequent treatment problem in orthodontic practice. Aim & objectives of the present case report was to evaluate the management of skeletal Class II division 1 malocclusion in non growing patient with extraction of upper first premolars. Clinical and cephalometric evaluation revealed skeletal Class II with Angles Class II division 1 malocclusion with mild mandibular anterior crowding and increased overjet, severe maxillary incisor proclination, mild mandibular crowding, exaggerated curve of spee, convex profile, incompetent lips, increased overjet and overbite. Maxillary first premolars were extracted followed by en-masse retraction of anteriors with the help of temporary anchorage devices (TADs) to avoid anchorage loss. Mandibular incisor was extracted to correct curve of spee. Following treatment marked improvement in patient’s smile, facial profile and lip competence were achieved and there was a remarkable increase in the patient’s confidence and quality of life.

Aim & objectives of the present case report was to evaluate the management of skeletal Class II division 1 malocclusion in non growing patient with extraction of upper first premolars. Clinical and cephalometric evaluation revealed skeletal Class II division 1 malocclusion with severe maxillary incisor proclination, convex profile, average mandibular plane angle, incompetent lips, increased overjet and overbite. After extraction of upper 1st premolars, canine retraction was done which was followed by retraction of severely proclined upper anterior teeth by judicious control of third order bend in rectangular stainless steel arch wire with “V” loop . For anchorage management, intra oral anchorage with tip back & toe in bends in stainless steel arch wire was satisfactory. Following treatment marked improvement in patient’s smile, facial profile and lip competence were achieved and there was a remarkable increase in the patient’s confidence and quality of life.

The changes in lip activity associated with retraction of the upper labial segment during treatment of Class II division 1 malocclusion were investigated electromyographically. In the lip seal position muscle activity of the circumoral muscles was much reduced after treatment, but the amount of reduction appeared to be unrelated to the amount of incisor retraction. In some cases lips which were judged to be incompetent before treatment were competent after treatment. Activity in the suprahyoid muscle group associated with upper incisor inclination and overjet when the lips were sealed was eliminated during swallowing.

ABSTRACT This case report describes the orthodontic and orthopedic treatment of an 18-year-old male patient who presented with prognathic maxilla, deep bite, low mandibular plane angle, and proclined incisors. Modified three-piece base arch was used for the intrusion and retraction of maxillary incisor. En masse retraction was achieved in 6 months. Reduced time for retraction was attributed to a single stage of retraction unlike Burstone three-piece intrusion base arch where canines are individually retracted followed by retraction of incisors. A modified utility arch was used in lower arch followed by a continuous archwire technique. The case was finished using bite settling elastics on a continuous archwire. The step between canine and premolar was corrected in the finishing phase of treatment. The final treatment outcomes were satisfactory and true intrusion was achieved with proper selection of biomechanics. How to cite this article Lekhadia DR, Hegde G.

Introduction: Orthodontic treatment of class II division 1 malocclusion by extracting the maxillary first premolar causes vertical dimensional change is still a matter of debate. The purpose of this research was to determine the vertical changes of the lower anterior facial height and maxillary incisor vertical dimensions in class II division 1 malocclusion after orthodontic treatment with Edgewise technique. Materials and Methods: This study was conducted on the cephalometry of 24 patients before and after orthodontic treatment with inclusion criteria as follows: Angle Class II division 1  malocclusion, aged 18-30 years old. Measurements were taken for the lower anterior facial height (ANS - Me) and maxillary incisor vertical dimensions by performing an Upper Anterior Dental Height (UADH). Data analysis used was the Wilcoxon test for unpaired data. Results: The result of p-value = 0.195 > 0.05 for lower anterior face height showed no significant difference; and p-value = 0.878 > 0.05 for UADH also showed no significant difference. Conclusion: Orthodontic treatment for class II division 1 malocclusion with the removal of two premolars does not change the lower anterior facial height and maxillary incisor vertical dimensions.

Objective: To determine maxillary and mandibular incisor inclination in Class II Division 1 malocclusion among different vertical skeletal type Chinese children. Materials & Method: Lateral cephalograms of Class II Division I malocclusion cases of 120 Chinese children (male-55, female-65) of the age range 12-14 years were divided into three vertical skeletal types (low angle, average angle, high angle) based on Sella-Nasion to Mandibular plane angle. To determine incisor inclination, lateral cephalometric radiographs were measured and analyzed using factorial analysis. All angular parameters were processed using ANOVA and t-test. Maxillary and mandibular incisor inclinations were discussed in detail among three vertical facial skeletal types. Result: The maxillary and mandibular incisors of low angle individuals were found to be proclined more than those with high and average angle individuals. Conclusion: Different vertical facial types of Class II Division I malocclusion in early permanent dentition accord to establish discriminate values to set up the cephalometric standards for diagnosis and treatment planning for the clinicians.
