This book was released on 2009 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background and significance . Class II malocclusion is observed in 15% of the population. Adolescent patients with mandibular deficiency can be treated with functional appliances, like the mandibular anterior repositioning appliance (MARA) or the Twin-Block appliance (TB). Clinically, the TB appliance seems to facilitate better vertical development than the MARA because it allows for molar eruption. Purpose . To compare vertical development between patients treated with MARA or TB appliance. Methods . Records of patients treated with MARA (n=25) and those treated with TB (n=28) obtained from a private practice. Cephalometric X-rays were analyzed at (T1) and at (T2). Results from the two groups were compared using independent groups t-test. Results . Treatment with MARA resulted in less vertical development. Conclusion . Patients with a deep bite should be treated using a Twin-Block appliance to allow for molar eruption. Patients with a normal or open bite should be treated using a MARA to limit further vertical development.

This book was released on 2013 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objectives: To determine the skeletal and dentoalveolar effects produced by the MARA functional appliance in the treatment of growing patients with Class II malocclusions. Materials and Methods: A retrospective study was conducted using lateral cephalograms of patients consecutively treated with the MARA appliance (n=40) during their skeletal growth spurt as evaluated by the improved cervical vertebral maturation method recommended by Baccetti et al. A comparison was made with 24 untreated Class II control subjects obtained from the University of Michigan growth study and matched with the experimental groups for skeletal age, sex and craniofacial morphology. Cephalograms were taken at three time points: [T1] pre-treatment; [T2] post-functional appliance treatment; and [T3] fixed orthodontic treatment completion. Treatment changes were evaluated between the time points using 35 variables. Data were analyzed using independent t-tests. Results: At the post-functional appliances' phase (T1-T2), the MARA appliance showed significant increases in the total mandibular length, ramus height and anterior/posterior facial heights. These effects continued during the fixed orthodontic treatment stage (T2-T3). The net changes (T1-T3) revealed significant mandibular growth enhancement with the MARA appliance (+2. 7mm) in comparison to untreated controls. The appliance also caused 5. 2o of flaring in the mandibular incisors, as well as significant decreases in overjet, overbite and inter-incisal angle. Conclusion: Overall, the MARA appliance showed significant skeletal and dentoalveolar changes resulting in normalization of the Class II malocclusion.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: To evaluate the cephalometric skeletal and dentoalveolar short-term effects of Twin Block (TB) and van Beek Headgear Activator (vBHGA) appliances, in the correction of skeletal Class II malocclusion (ANB≥5) in growing patients as determined by the CVM method, in comparison with a growing untreated control. Materials and Methods: Pre (T1) and post-functional appliance (T2) lateral cephalograms were retrospectively obtained for the vBHGA (n=46), TB (n=45), and control (n=45) groups. The groups were also stratified into horizontal or vertical using Jarabak ratio values. A customized cephalometric analysis and superimposition-based measurements were performed. Analysis of Covariance (ANCOVA) regression models at the 5% level of significance were used. Results: Both appliances equally improved the jaw relationship. For vBHGA, they were: ANB (1.590; p=0.00) and Harvold Difference (2.51mm; p

Book Synopsis Cephalometric Changes Observed Following Long Term Use of the Bimler Functional Appliance in Class II Division 1 Malocclusions by :
Download or read book Cephalometric Changes Observed Following Long Term Use of the Bimler Functional Appliance in Class II Division 1 Malocclusions written by and published by . This book was released on 2008 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Bimler appliance is one of many functional appliances developed during the evolution of functional orthodontics and is still used to treat patients today. Dr. Bimler was a firm believer that functional appliances should treat the patient to their individual limits of adaptability, and treating beyond this adaptability was an invitation for future relapse. The goal of this study was to evaluate cephalometric changes observed in Class II division 1 patients who received long-term therapy utilizing the Bimler appliance. Twenty-five patients (15 females and 10 males) for inclusion in this study were drawn from records donated to the University at Buffalo School of Dental Medicine from the practice of the late HP Bimler in Wiesbaden, Germany. All patients showed Class II division 1 malocclusions at the start of treatment, were treated solely using the Bimler appliance for an extended treatment period, and had initial, progress, and final cephalometric radiographs available. Each radiograph was digitized and traced by a single operator utilizing the Dolphin Imaging System, and a cephalometric analysis was completed. From the results, it would appear that saggital correction in Class II division 1 cases was achieved mainly via dental changes, with only a minor contribution by changes in skeletal relationships. Treatment effects of the Bimler appliance showed statistically significant changes from baseline (P0.05) for all measures except FMA, interincisal angle, and Wits. The decrease in overjet was achieved both by a significant uprighting of the maxillary incisors ( -6.04) and flaring (proclination) of the lower incisors (4.956) over the entire treatment period. Significantly larger effects were seen during the initial treatment period (T1-T2) compared to the later treatment period (T2-T3) for ANB, ANS-Me, U1-SN, and L1-MP (p0.05). These measures accounted for most of the treatment effect of the appliance that could not be attributed to normal growth alone. Results from this study suggests that clinicians who utilize the Bimler appliance to treat Class II division 1 cases should expect to see a majority of the correction during the first 24 months of treatment, and should expect diminished treatment effects should the therapy continue significantly beyond that point.

This book was released on 2012 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this study was to compare cephalometric changes in skeletal and dento-alveolar parameters in cases treated by these two different orthodontic techniques. This was to be established by calculating and comparing the pre- and post-treatment cephalometric variables of cases treated with these techniques by looking at the skeletal and dento-alveolar measurements. Thirty Tip-Edge and thirty edgewise treated cases that had class II malocclusion, had extraction of four premolars and were treated with Class II elastics were selected. The gender distribution between the Tip-Edge and the edgewise techniques were 47% and 60% respectively for females. For males it was 53% in Tip-Edge and 40% in the edgewise techniques. The mean ages were 17.8 for Tip-Edge and 13.8 for edgewise techniques. The pre- and post-cephalometric radiographs were collected and the landmarks used were digitized using a Dolphin 10.5 Imaging and management solutions program
