Abstract
BackgroundTo evaluate the closure of midline diastema using the Neodymium-Iron-Boron magnets and to compare the treatment duration of midline diastemas with the use of magnets compared to regular orthodontic treatment.Material and MethodsThirty patients with age group 12 to 30 years with the midline diastema ranging from 0.5 to 3mm were selected. These patients were divided into two groups. Diastema closure in one group was accomplished by conventional method, in other group was done with Ne2Fe14B magnets. These magnets were fitted to the labial surfaces of the maxillary central incisors such a way that the opposite poles of the magnets face each other. At each appointment, study models and radiographs were taken for study subjects and the midline diastema was measured using digital vernier calipers on the study models obtained. Descriptive statistics carried out using Paired t-test.ResultsSubjects treated with Ne2Fe14B magnets showed a significant difference compared to fixed orthodontic appliance subjects with respect to time of closure, rate of space closure and incisal inclination. Significant difference between 2 groups with reduction of 64.6 days in time to diastema closure in subjects treated with Ne2Fe14B magnets (P<0.05).ConclusionsNe2Fe14B magnets more efficient in complete closure of mid line diastema in less duration of time. Key words:Midline diastema, Ne2Fe14B magnets, rare earth magnets, space closure.
Highlights
Angle (1907) described the dental midline diastema as a rather common form of incomplete occlusion characterized by a space between the maxillary and less frequent mandie164
Midline diastema is frequently cited as a malocclusion with high relapse incidence
The present study considered the neodymium-iron-boron (Ne2Fe14B) rare earth magnets as a mode in the closure of midline diastema
Summary
Broadbent described the normal closure of this space by the medial erupting path of the maxillary lateral incisors & canines. The present study considered the neodymium-iron-boron (Ne2Fe14B) rare earth magnets as a mode in the closure of midline diastema. Advantages of magnetic force delivery include minimal tooth tipping, less chair time, no further activations, maintainable oral hygiene, cheaper and recyclable, no friction, and no material fatigue [5]. The purpose of the study is to evaluate the closure of midline diastema using the Ne2Fe14B magnets and compare its treatment duration with the non- magnetic regular fixed orthodontic appliance (Straight wire Appliance). To evaluate the closure of midline diastema using the Neodymium-Iron-Boron magnets and to compare the treatment duration of midline diastemas with the use of magnets compared to regular orthodontic treatment
