Book Description
Introduction: Class II malocclusions are of interest to the practicing orthodontists because they constitute a significant percentage of the cases they treat. Over the years, a substantial number of approaches and appliances had been developed for Class II malocclusion treatment. The concept of fixed functional appliance such as Forsus appliance was suggested as an option to overcome the lack of compliance with some patients. Many studies were published about Twin Block but only few studies have evaluated the treatment effects of the Forsus Appliance. Objectives: This study will evaluate the effects of the Forsus appliance in comparison with Twin Block appliance and a non-treated control group for the treatment of Class II malocclusion. Methods: The present retrospective study was carried out on three groups: Twin Block group (37 subjects, mean age 11. 2 Y), Forsus group (30 subjects, mean age 12. 9 Y), and a non-treated control group (25 subjects, mean age 12. 6 Y). The study was based on the evaluation of the lateral cephalometric radiographs of pre-treatment, as well as at T2 (posts appliance removal/ equivalent timeframe in controls. Cephalometric changes were evaluated using the Clark analysis including 27 measurements. Results: The results showed that sagittal correction of Class II appeared to be mainly achieved by dentoalveolar change changes only in Forsus group. The Twin Block appliance therapy was able to induce both skeletal and dentoalveolar changes. A favourable influence on the facial convexity could be achieved in both groups. In the Twin Block group, skeletal alterations that contributed to skeletal correction mainly took place in the mandibular ramus, while these changes were significant different form the controls. The effects on the upper incisors varied between the two functional appliances. Large significant upper incisors retroclination occurred with the Twin Block ( -12. 42 degree) while - 4℗ʻ only observed in Forsus group. The lower incisors were proclined slightly more in Forsus than Twin Block group. No significant change of the incisor position of the controls was present. Incisor overjet reduction was larger in amount in Twin Block (7. 03 mm) and 4 mm in the Forsus group. The overjet correction was about 60% of the initial overjet in both experimental groups. Molar relation was corrected in both functional groups resulting in a Class I relation, while no change appeared in the control sample.

Book Description
Twin Block appliances are simple bite blocks that are designed for full-time wear. They achieve rapid functional correction of malocclusion (misalignment of upper and lower teeth) by the transmission of favourable occlusal forces to occlusal inclined planes that cover the posterior teeth. The forces of occlusion are used as the functional mechanism to correct the malocclusion (www.twinblocks.com). Beginning with an introduction to orthodontics and twin blocks, the next chapters describe growth studies and diagnosis and treatment planning. Each of the following sections discusses the use of twin blocks for different types of malocclusion. With a focus on the latest developments in functional therapy, the book offers guidance on diagnosis, treatment planning, case selection, appliance design and clinical management. Written by the internationally recognised Orthodontist William Clark from Fife, UK, who also invented Twin Blocks, this comprehensive guide includes nearly 600 clinical photographs and illustrations. Key points Comprehensive guide to use of Twin Blocks in treatment of malocclusion Focus on latest developments in functional therapy Written by UK-based inventor of Twin Blocks Includes nearly 600 images and illustrations

Book Description
Advanced oral and maxillofacial surgery encompasses a vast array of diseases, disorders, defects, and deformities as well as injuries of the mouth, head, face, and jaws. It relates not only to treatment of impacted teeth, facial pain, misaligned jaws, facial trauma, oral cancers, jaw cysts, and tumors but also to facial cosmetic surgery and placement of dental and facial implants. This specialty is evolving alongside advancements in technology and instrumentation. Volume 1 has topped 132,000 chapter downloads so far, and Volume 2 is being downloaded at the same pace! Volume 3 is basically the sequel to Volumes 1 and 2; 93 specialists from nine countries contributed to 32 chapters providing comprehensive coverage of advanced topics in OMF surgery.

ABSTRACT Objectives: The purpose of this study is to evaluate and compare the skeletal and dentoalveolar effects of the Stainless Steel Edgewise Crown Herbst, and the Forsus Fatigue Resistant Device in the treatment of the class II malocclusion in adolescent patients. Materials and methods: This study is a retrospective clinical trial which was conducted on records for Class II patients who were treated with two different appliances. Results were compared with an untreated control group. The first group consists of 30 patients (mean age 12. 9 + 1. 18) who were treated with Forsus FRD, the second group consists of 28 patients (mean age 11. 7+1. 66) who were treated with edgewise crown Herbst, and the third group was a class II untreated control group which had 25 subjects (mean age 12. 6+ 0. 91). Lateral cephalograms were taken before functional appliance placement [T1] and after functional appliance removal [T2] to evaluate treatment effects. Analyses of Variances (ANOVA) followed by TukeyHSD post-hoc test were used to compare changes between groups at p

Book Description
Class II malocclusions affect over twenty percent of the population. Over the years numerous appliances have been invented and modified in order to treat this type of maloclussion. Functional appliances have been advocated for their ability to assist in mandibular growth along with restraint of maxillary growth, as two-thirds of Class II malocclusions are classified with retrognathic. Publications from the following electronic databases were searched: PubMed, Web of Science, Cochrane Library and Science Direct. Searches included any article published until July 13, 2012. Searches were performed under the term "ForsusTM." These searches yielded sixty-one (61) articles. These were reviewed for relevance based on inclusion and exclusion criteria. Articles were excluded if they did not measure the effectiveness of ForsusTM treatment or were not written in English. Seven (7) articles were deemed of relevance with a high quality study design and were included in this study for evaluation. The current literature suggests that Class II treatment with the ForsusTM appliance is an effective and efficient method to treat Class II maloclussions in six months. It produces mainly a restraining effect on maxillary growth, while the Class II molar correction is derived primarily from dentoalveolar changes. Overjet and overbite is reduced through proclination, mesialization and intrusion of the mandibular incisors and retrusion and extrusion of the maxillary incisors. There is also a distalizing and intrusive force on the maxillary first molars which make this appliance ideal for high angle and open bite cases. Some other noted effects are palatal and occlusal plane clockwise rotation and slight expansion of the intermolar widths after treatment. The other obvious advantage is the continuous wear guaranteed by this non compliance method of treatment.
