Abstract

In routine orthodontics practice anchorage is a critical factors that determining the success of an orthodontic treatment. For many years’ anchorage has been a strenuous factor. Many modalities have been tried for preventing the anchorage loss by using the extra oral and intraoral devices according to various scientific literature, yet the orthodontists did not find any convenient solutions to solve this problem until the mini- implants were emerged to the speciality. During the early 20 century introduction of various skeletal anchorage devices which includes prosthetic implants, palatal implants, mini-plates and screws. The implants used in orthodontics for the purpose of effective treatment are also known as Temporary Anchorage Devices (TADs), which helps in bringing down the strenuous efforts employed to prevent anchorage loss and they are easy and small and can be insert and remove without stenos efforts, they can be immediately loaded after insertion, and they can provide absolute anchorage for orthodontic treatment, which require minimal need patient compliance there by increasing its popularity. This article gives a brief reviews of indications, contraindications, safety zones for TADs, their insertion procedure, complications, failures and medico legal aspects.   Keywords: Orthodontic mini implants, Temporary anchorage devices, Anchorage

Abstract

Background: Blood groups may be associated with some diseases, deformities and, malocclusion and may have genetical relationship in general. Some studies showed that the relationship exists whereas others could not find any relationship. Therefore, this study is carried out to explore the relationship between blood group and malocclusion Materials and Methods: This sample of 132 subjects consisted of 56 males and 76 females reporting to the department of orthodontics for treatment of malocclusion. These samples were divided into Class I , Class II and Class III malocclusion. Patient’s blood group was determined using slide method and divided into ABO and Rh blood groups. Results were tabulated and organized based on Class I , Class II and Class III malocclusion to find out the relationship between blood groups and malocclusion Results: This study was conducted to assess correlation between blood group using different dental and skeletal parameters. The 132 subjects selected by convenience sampling method consisted of class I -79 cases, class II -44 cases and class III -9 cases. The result showed that a statistically significant relationship exists between ABO blood groups and sagittal skeletal parametersYEN angle Conclusion: There is an association between blood groups and YEN angle (Sagittal parameter) . B and O blood group shows statistical significance with YEN angle. And there is no association between SN-GoGn, FMA and Y axis (Vertical parameter)   Keywords: Malocclusion, Yen Angle
