Available in PDF, EPUB and Kindle. Book excerpt: Objective: The purpose of this study is to determine the short-term skeletal and dental effects that occur as a result of Class II malocclusion correction utilizing the Carrière! Distalizer as compared to best-matched controls. Methods: This is a retrospective cohort cephalometric study using lateral cephalometric films of 25 (14 male, 11 female, average age 13y 6m) class II patients consecutively treated with the Carrière Distalizer compared with 36 (19 male, 17 female, 13y 2m) untreated class II control subjects from a historical database best-matched based upon age, sex and skeletal classifications. Pretreatment and posttreatment lateral head films were analyzed with conventional cephalometric analysis to evaluate treatment effects. Results: Class II correction was accomplished by 2.46 apical base change, 1.24 mm distal movement of the maxillary movement, 4.8° distal tip and 2.64 mm mesial movement of the mandibular molars. Other profound treatment changes occurred include significant increased lower incisor proclination, 4.83° and a steepened functional occlusal plane, 1.3°. Conclusion: The Carrière Distalizer is an effective means to establish a class I occlusal platform in approximately 4 months during the initial phase of comprehensive orthodontic treatment.

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

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 2006 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall goal of this research project is to evaluate the skeletal and dental changes when a Class II malocclusion is corrected using the Herbst appliances compared to similar malocclusions treated with Class II elastics; for the purposes of this study, this will be referred to as the control group. More specifically, cephalometric radiographs will be used to: (1) study the SNA, SNB, and ANB angle changes in Class II malocclusion patients who receive treatment with elastics or a Herbst appliance, (2) study the change in the lower incisor to the mandibular plane angle (IMPA), and compare the results with a control group of patients. Further, the pre-Herbst and post-Herbst measurements will be compared to determine if there is a significant change. The hypothesis will be that the Herbst appliance will cause a change in the SNA, SNB, and ANB angles, and alter the IMPA as compared to Class II correction with elastics.

Book Synopsis Skeletal and Dental Response to Long-Term Herbst Appliance Treatment by : Curiel Bruno
Download or read book Skeletal and Dental Response to Long-Term Herbst Appliance Treatment written by Curiel Bruno and published by LAP Lambert Academic Publishing. This book was released on 2016-01-20 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: In orthodontics, one frequent problem is the correction of Class II malocclusion. This might be due to a mandible which is backward positioned compared to the face. One way to correct this malocclusion is the use of functional appliance which brings the mandible forward and then improves the profile and facial aesthetics. One of the most famous functional appliance used today is the Herbst appliance (bonded to the teeth) which works continuously. As the effects of the functional therapy are still controversial, we can notice that all studies using the Herbst appliance have been conducted over a short period of time between (6 to 8 months). As the length of the treatment might be one of the main parameter in the success or in the failure of such treatment, we decided to increase it to 20 months. The objectives in our studt are therefore to evaluate the skeletal and dental changes that occurred in the maxilla and the mandible after 20 months of treatment using cephalometrics radiographs and to assess any changes of the condyle to the glenoid fossa at the end of Herbst treatment using CT scans.

Book Synopsis Treatment Effects of the Twin Block Functional Appliance and the Mandibular Anterior Repositioning Appliance (MARA) in Patients with Class II Malocclusions℗ by : Eva-Maria Moll
Download or read book Treatment Effects of the Twin Block Functional Appliance and the Mandibular Anterior Repositioning Appliance (MARA) in Patients with Class II Malocclusions℗ written by Eva-Maria Moll and published by . This book was released on 2012 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: AbstractIntroduction: Class II malocclusions represent one of the most prevalent forms of malocclusion encountered in routine orthodontic practice. In order to correct a Class II malocclusion, miscellaneous orthopedic functional appliances with a broad spectrum of diverse appliance designs have been continuously developed. While the Twin Block is known as one of the best researched functional appliances, only few studies have evaluated the treatment efficacy of the Mandibular Anterior Repositioning Appliance (MARA) since its development in 1991. Thus, the purpose of this retrospective study was to evaluate and compare the skeletal and dentoalveolar effects of the Twin-block and the Mandibular Anterior Repositioning Appliance (MARA) in the treatment of adolescent patients with Class II malocclusions compared to controls. Materials and Methods: The present retrospective study was carried out on three samples: a Twin Block sample, a MARA sample, and a control sample.^The study was based on the evaluation of the lateral cephalometric radiographs of a total of 96 cases at T1 (pre-functional treatment), as well as at T2 (post-functional treatment/ equivalent timeframe in controls). The Twin Block sample with 37 cases represented the largest sample, consisting of 24 females and 13 males. It was treated by the inventor Dr. Clark in his private practice in Fife, Scotland, UK. The average age for the Twin Block group at T1 is 11 years of age. The MARA group consisted of a total of 34 cases: 16 females and 18 males. The average age of the MARA sample at T1 was consistent with the Twin Block sample (11 years of age). The MARA sample was respectively treated by its inventor Dr. Toll, Bad Soden, Germany. The control group was based on 25 cases (12 female and 13 male) obtained from the Michigan growth study. The untreated control group was matched to the MARA sample.^Lateral cephalometric radiographs were taken at the beginning of treatment (T1) and post-functional treatment (T2). Cephalometric changes were evaluated using the Clark analysis including 27 measurements. The MARA, and the control sample were evaluated by an independent commercial company, Rocky Mountain Data Systems, using Joe Ceph by Rocky Mountain Orthodontics. The Twin-Block sample was analyzed by Dr. Clark using Quick CephTM. Results: The results showed that sagittal correction of Class II appeared to be mainly achieved by dental changes, being accompanied by skeletal adaptation. A positive influence of the position of point Pogonion could be achieved in both groups resulting in a considerable decrease of the facial convexity. Skeletal alterations that contributed to skeletal adapations mainly took place in the mandibular ramus, while these changes were significant different form the controls.^No significant alteration of the mandibular plane angle could be determined in all three groups. The current study showed a lower incisors flaring of 5. 47 degree with the MARA appliance and 2. 11 degree with the Twin Block. The effects on the upper incisors varied between the two functional appliances. Slight protrusion of the upper incisors took place with the MARA (+5. 06 degree) and a significant retroclination occurred with the Twin Block ( -12. 42 degree). Accordingly, the interincisal angle decreased in the Twin Block sample and increased on the other hand with the MARA. No significant change of the incisor position of the controls was present. Incisor overjet decreased of about 7. 03 mm in the Twin Block group and 2. 46 mm in the MARA sample. Incisor overbite decreased about 1. 34 mm with the Twin Block and 2. 92 mm with the MARA. Molar relation was corrected in both functional groups resulting in a Class I relation, while no change appeared in the control sample.^While a slight distalizing effect on the upper first molars could be seen in the Twin Block sample ( -0. 06 mm), no such effect could be determined for the MARA appliance (+0. 96 mm). Conclusion: Both appliances resulted in a Class I relationship. Skeletal changes were very similar in both appliances. Overall the Twin Block seemed to be slightly superior to the MARA appliance. Key words: Fixed functional appliance; Twin Block; MARA; Class II malocclusion; Clark analysis.

Book Synopsis Open-Bite Malocclusion by : Guilherme Janson
Download or read book Open-Bite Malocclusion written by Guilherme Janson and published by John Wiley & Sons. This book was released on 2013-10-29 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Open-Bite Malocclusion: Treatment and Stability presents the etiology, treatment, and its stability of anterior open bite malocclusion in the early, mixed, and permanent dentitions. Special emphasis is devoted to orthodontic treatment and its stability in the permanent dentition because this is the time when treatment of open bite presents greater relapse. Appropriate for clinicians, orthodontic residents, and dental students, Open-Bite Malocclusion covers the most simple treatment approaches to the most complex, from orthodontic devices to tooth extraction to surgery. Unique to this book is the discussion of post-treatment stability. Drs. Janson and Valarelli highlight the post-treatment changes and presents strategies to increase treatment stability. This allows the clinician to be able to predict the stability probabilities when treating anterior open bite malocclusions in the permanent dentition either with or without extraction, orthodontic-surgical therapy, or with occlusal adjustment.
