The orthodontic treatment of an adult patient with a skeletal Class III malocclusion, increased anterior facial height, negative overjet, and bilateral posterior crossbite is presented. Treatment options included mandibular first premolar or third molar extractions with dentoalveolar compensation or combined surgical-orthodontic treatment. Mandibular third molar extraction with dentoalveolar co...

Events of the past decade or so argue that there is little support in the literature for much of the specialty's treatment portfolio. The resulting call for 'evidence-based' treatment (not to mention the obvious intellectual bankruptcy of much of the clinical literature) has prompted many to argue that the randomized clinical trial (RCT) represents the future of orthodontic clinical investigati...

The orthodontic treatment of patients with pre-existing root resorption (RR) is often difficult due to the increased risk progression and a compromised outcome can be expected. plan in such situations should comprise sparing strategy, which includes reducing duration fixed appliances, non-extraction treatment, force levels, avoiding intrusion at-risk teeth, amount apical movement affected teeth...

OBJECTIVE To analyze the long-term changes in maxillary arch widths and buccal corridor ratios in orthodontic patients treated with and without premolar extractions. METHODS The study included 53 patients who were divided into the extraction (n = 28) and nonextraction (n = 25) groups. These patients had complete orthodontic records from the pretreatment (T1), posttreatment (T2), and postreten...

BACKGROUND The extraction rate in orthodontics varies throughout the years. While the extraction decision is easily made or excluded in clear-cut cases, it still remains controversial what makes an orthodontist decide to extract in borderline cases. The aim of this retrospective study was to identify the percentage of extraction cases in a large group of Class I malocclusions and to clarify whi...

Introduction: The aim of this study was to recognize and investigate the expectations of patients and their parents from orthodontic treatment in order to increase the satisfaction from treatment outcome and enhance the patients’ cooperation in Babol in 2017. Materials & Methods: Totally, 200 people (100 patients aged 12-18 with one of their parents) who were attending for their first or...

OBJECTIVE To measure aspartate aminotransferase (AST) activity in the pulp of teeth treated with fixed appliances for 6 months, and compare it with AST activity measured in untreated teeth. METHODS The study sample consisted of 16 healthy subjects (mean age 25.7 ± 4.3 years) who required the extraction of maxillary premolars for orthodontic reasons. Of these, 6 individuals had a total of 11 s...

Traumatic dental injury can result in avulsion of anterior teeth. In young patients, it is a challenge to the dental professional because after replantation, late complications such as ankylosis require tooth extraction. Although prosthetic and orthodontic treatment, and implant placement have been described as the options for intervention, autogenous tooth transplantation could be an effective...

Extraction spaces may be needed to achieve specific orthodontic goals of positioning the dentition in harmony with the craniofacial complex. However, the fundamental reality that determines the occlusion final position is the control exerted by the orthodontist while closing the extraction spaces. A specific treatment objective may require the posterior teeth to remain in a constant position an...

MANY APPROACHES FOR CROWDED MANDIBULAR ANTERIOR TEETH ARE CURRENTLY EMPLOYED: distal movement of posterior teeth, lateral movement of canines, labial movement of incisors, interproximal enamel reduction, removal of premolars, removal of one or two incisors, and various combinations of the above. Selecting the best treatment is often difficult, and all guidelines do not apply to every case. Trea...
