BACKGROUND AND AIM: Tooth extraction as a part of orthodontic treatment plan to create space for leveling and aligning teeth or causing tooth movement leads to changes in arch width and length. The outcome of these changes is important for the clinicians and affects the treatment and retention plans. Despite some previous studies, data in this regard are still scarce and further investigation i...

This article reports the orthodontic diagnosis and treatment planning carried out with a 14-year and 5-month-old female patient with esthetic and functional complaints. She presented an Angle Class I malocclusion, anterior crossbite and severe crowding in both maxillary and mandibular arches, in addition to a lightly concave straight facial profile. Orthodontic treatment did not require extract...

Cooperation of the patient during orthodontic treatment is a major determinant of a successful treatment result. Unfortunately, noncompliance is a serious problem in orthodontics. A patient’s noncompliance can result in a longer treatment time, destruction of the teeth and periodontium, extraction of additional teeth, collapse of a corrected malocclusion after treatment, frustration for the pat...

distraction osteogenesis method (do) in bone lengthening and rapid midpalatal expansion have shown the great ability of osteognic tissues for rapid bone formation under distraction force and special protocol with optimum rate of one millimeter per day. periodontal membrane of teeth (pdm) is the extension of periostium in the alveolar socked. orthodontic force distracts pdm fibers in the tension...

AIM To investigate if premature extraction of primary teeth was associated with orthodontic need in the permanent dentition. STUDY DESIGN This was a case-control study based on retrospective dental records. METHODS As part of NHS (UK) Dental Epidemiology Programme a sample of 366, 12-year-old children from Bradford and Airedale were examined. The survey collected data on patient demographic...

OBJECTIVES One major drawback of orthodontic treatment is its long duration due to slow tooth movement and the pain at the onset of treatment following application of forces. There is controversy regarding the efficacy of laser for decreasing the treatment time and pain of orthodontic treatment. The purpose of this study was to investigate the effect of low level diode laser on the rate of orth...

Results of orthodontic Class II malocclusion treatment can be influenced by inherent characteristics such as patient age, malocclusion severity and degree of compliance, or even by factors regarding the orthodontist’s subjective preference such as the treatment protocol. Basically, Class II treatment protocols involve nonextraction or extraction of two or four premolars. However, a greater trea...

The purpose of this paper was to present the surgical exposure and orthodontic treatment of an 11-year-old boy with horizontally impacted permanent maxillary central incisors associated with bilateral mesiodentes. Panaromic and upper anterior occlusal radiographs showed horizontally impacted maxillary central incisors, vertically impacted molariform mesiodens, and rotated mesiodens located at t...
