Morphometric assessment of the sella turcica in different morphologic types of Class II malocclusion: a retrospective study

ABSTRACT Objectives: To test the null hypotheses that the positions of the glenoid fossae and mandibular condyles are identical on the Class I and Class II sides of patients with Class II subdivision malocclusion. Materials and Methods: Retrospective three-dimensional (3D) assessments of the positions of the glenoid fossae and mandibular condyles were made in patients with Class II malocclusion. Relative to a fiducial reference at the anterior cranial base, distances from the glenoid fossae and condyles were calculated in pretreatment cone beam computed tomographic scans of 82 patients: 41 with Class II and 41 with Class II subdivision malocclusions. The 3D distances from glenoid fossae to sella turcica in the X (right-left), Y (anterior-posterior), Z (inferior-superior) projections were calculated. Results: Patients with Class II malocclusion displayed a symmetric position of the glenoid fossae and condyles with no statistically significant differences between sides (P > .05), whereas patients with Class II subdivision showed asymmetry in the distance between the glenoid fossae and anterior cranial base or sella turcica (P < .05), with distally and laterally positioned glenoid fossae on the Class II side. (P < .05). Male patients had greater distances between glenoid fossae and anterior cranial fossae (P < .05). The condylar position relative to the glenoid fossae did not differ between the two malocclusion groups nor between males and females (P > .05). Conclusions: The null hypotheses were rejected. Patients with Class II subdivision malocclusion displayed asymmetrically positioned right- and left-side glenoid fossae, with a distally and laterally positioned Class II side, although the condyles were symmetrically positioned within the glenoid fossae.

ABSTRACT Introduction Numerous appliances are present for the management of class II malocclusion. We have conducted a study to compare the clinical complications during treatment with either a removable mandibular acrylic splint (RMS) or with a cantilever Herbst (HC) appliance for the management of class II malocclusion. Materials and methods This study consisted of records of 114 patients (61 males, 53 females), who were divided into two groups. Group I received RMS and group II received HC for the treatment of class II, Division 1 malocclusion. They were further subdivided according to the telescopic system used [Dentaurum type I or propulsor mandibular abzil (PMA)] and fixation mode (splint with crowns or GripTite bands). Patients’ clinical records were assessed to identify clinical complications. Results The results of the study showed that the incidence of complications during treatment in both groups was statistically nonsignificant. The complications with either crown or band were also statistically nonsignificant. The Dentaurum group showed more susceptibility to complications than the PMA group. Conclusion The PMA telescopic system is more efficient as compared with Dentaurum. Complication resulting from Herbst appliance is independent type of appliance used and mode of fixation. Clinical significance Herbst appliance is the treatment of choice for class II malocclusion. How to cite this article Kanuru RK, Bhasin V, Khatri A, Dodda KK, Singh E, Grover S.

Treatment Alternatives

Class II malocclusion has a high incidence in the population, which may compromise smile aesthetics, occlusion function and stability. Skeletal Class II may affect facial aesthetics and upper airway volume. Class II malocclusion is routinely associated with skeletal Class II condition, having as treatment alternatives the use of Extra Buccal Appliance (EBA) or removable or fixed propulsor appliance. This article describes a case of a patient who did not accept the use of EBA and so it was fitted a Flex Developer propulsor for Class II correction and discussed the advantages and disadvantages of therapeutic alternatives for Class II correction.
