ABSTRACT
Malpositioned teeth are responsible for aesthetic and occlusal aberrations in many adults. Orthodontic movement is considered a “periodontal phenomenon” because all the periodontal tissues are involved in tooth movement. Lengthy orthodontic treatment time has been linked to an increased risk of root resorption, gingival inflammation, decalcification, and dental caries. 2 Therefore, reducing the treatment time is an appropriate goal, which requires increasing the rate of tooth movement. To meet the constant demand to shorten the treatment time and to maintain the integrity of periodontal structures an alternative clinical procedure has been popularized, known as Accelerated Osteogenic Orthodontics (AOO) and, more recently, the Periodontally Accelerated Osteogenic orthodontics. This article over review of literature of this technique and describes recent advances in this procedure.
ABSTRACT
Abstracts: Background: Implant dentistry provides a more functional and attractive alternative to removable prosthesis. Despite the high success rate shown by longitudinal studies, failures do occur, even in patients who present appropriate clinical conditions. In most of the clinical situations implant replacement is the only alternative treatment in patients with failed implants. Here is a case report which describes the possible etiology, diagnosis and management of early failed dental implants. Surgical management includes the reimplantation of failed implants after debridement of osteotomy site and decontamination of implant surface. Early diagnosis of implant failure, proper clinical evaluation and long term follow up are of paramount importance for such reimplantation of failed dental implants.
