Book Description
The effect of the Bimler functional appliance on the treatment of Class III malocclusion is unknown as no previous study has evaluated the effect of this appliance on Class III patients. Indeed, there are very few, if any, studies that have reported the effect of the functional appliances on Class III malocclusions. It was thus the goal of this study to investigate the changes that results from the treatment of Class III patients with the type C Bimler appliance. Materials and methods. Thirty patients with Class III malocclusion (12 males and 18 females) were included in this study. The mean age of the subjects was nine years and eight months at the beginning of the treatment. These patients were treated by Bimler with his type C functional appliance. The mean treatment period was two years and three months. The lateral cephalometric radiographs used in this study were analyzed at the start of treatment (T1) and at the end of the treatment (T2). Eight linear and six angular measurements were made to evaluate the changes achieved by the Bimler type C functional appliance. The Student's and paired t-test were used to analyze the data collected in this study. Results. For no measurement was there a statistically significant difference (p=0.05) between the males and the females. As a result, the separating by gender was abandoned, and the male and female treatment groups were combined to provide 30 subjects. The most significant changes observed were three angular measurements (ANB, Upper incisor to SN, IMPA) and seven linear measurements (Co-A, Co-Gn, Pg-Na perpendicular, ANS-Me, Wits, Overjet, Lower incisor to APo) (p

Book Description
The effect of the Bimler appliance on the treatment of Class II division I malocclusion is largely unknown, as few if any, independent studies have evaluated the effect of this specific appliance on Class II division I patients. The objective of the present study was to determine the clinical, and skeletal effects of the Bimler functional appliance when it is used to treat Class II division I malocclusions. The data for the present study were obtained from the records of patients treated by Dr Bimler in his private practice which is located in Wiesbaden in Germany. All of the class II division I cases used in the present study were selected randomly from the records compiled by Dr Bimler himself. The Cases were selected until a sufficient number (n=30) of records were collected. The records were selected to represent both sexes (14 males, and 16 females). Cephalometric measurements were made on radiographs taken at the commencement of treatment (T1) and as well as at the completion of treatment (T2). Nine linear and seven angular measurements were evaluated in this study. The average age of all of the patients was nine years and eight months, with the males being approximately two and one half months older than females when treatment was started. Treatment duration was approximately two and one half years for all of patients with the treatment for the male's lasting several weeks longer than the treatment for the females. This difference was not statistically significant (P=0.05). Each mean change was tested using a paired Student's t-test where the null hypothesis was that no change took place in each parameter from T1 to T2. In addition a test was done to determine if the amount of change that occurred was statistically different between the males and the females. Statistically significant changes associated with the Bimler treatment were observed for ten of the 16 measurements recorded. These measurements included the angle ANB, U1-L1 and U1-SN, the linear measurements Co-A, Co-Gn, Ar-Gn, ANS-Me, Wits, L1-Apo and Overjet. In no determination was there a statistically significant difference (ps0.05) between the males and the females. In this study it was concluded that: The clinical overjet was decreased by the increased forward growth of the mandible and by dentoalveolar changes. The Bimler appliance appears to have mainly skeletal effects with a few smaller, but significant, dentoalveolar effects. The appliance had little or no effect on the maxillary skeletal structures.

Book Description
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.
