The twin block appliance is widely considered as the most efficacious myofunctional appliance for treating skeletal class II malocclusion in growing patients. The success of treatment with any myofunctional appliance depends on a variety of factors, including the patient's age, growth status, growth pattern, the specific malocclusion being treated, patient compliance, the type of appliance, and other case selection criteria, such as clinical examination and certain cephalometric parameters that are not typically considered in routine practice. Among cephalometric parameters, the saddle angle is of utmost importance and should always be considered before commencing myofunctional therapy. Patients with a large saddle angle may have a class II skeletal relationship, characterized by a posteriorly positioned mandible. These cases can be more challenging to treat with functional appliances alone and may require additional orthodontic or surgical interventions. This paper presents a detailed description of three cases illustrating the importance of the saddle angle in the success of myofunctional therapy.","PeriodicalId":376004,"journal":{"name":"Journal of Contemporary Orthodontics","volume":"4 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139774659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Use of mini implants is one of the innovative approach for complex tooth movements such as mesialisation. Space closure from distal to mesial is one of the most difficult orthodontic tasks. Tooth-borne anchorage limits the scale of tooth movement. Extraoral or intraoral appliances are used especially for unilateral space closure. As an alternative to conventional mesialization appliances, osseointegrated implants may be used for maximum anchorage in orthodontic treatment. The use of direct anchorage in the form of installed mini-implant that is connected to the teeth requiring horizontal movement causes low levels of strains on anchor unit comparing to the results that were registered during indirect anchorage with one or two anchor teeth. This report presents the case of removal of mesiodens and blocked out and fractured premolar and the space closure by unilateral mesialisation with the help of mini implants and loops.","PeriodicalId":376004,"journal":{"name":"Journal of Contemporary Orthodontics","volume":"80 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139774959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results suggest a difference in dental age and chronological age in subject with vertical growth patterns. Vertical female growers showed early dental age maturation compared to chronological age. There was insignificant difference present in dental age and chronological age in horizontal growth patterns and average growth patterns. Insignificant intergroup difference was found in dental age between horizontal vs vertical, horizontal vs average and vertical vs average growth patterns. Subjects with vertical female growth patterns shows early dental age maturation than chronological age.
