Correction of dental crowding can be achieved with several orthodontic procedures like extraction of teeth, proximal stripping etc. In contemporary orthodontic practice, resolution of incisor crowding is most commonly achieved by the use of canine lacebacks. This method takes time, requires frequent activations and taxes anchorage since it involves the "PULL" mechanics. In order to overcome these disadvantages, mostly the time factor, we devised a method of using open coil NiTi spring on 0.016" SS wire piggy backed on the 0.014" heat activated NiTi base arch wire ligated only at the canines. This method, resolved the incisor crowding in almost one third of the time taken with the use of canine lacebacks. Moreover, the result was more physiologic since light continuous force was applied with the spring and it essentially eliminated the anchorage loss since it involved "PUSH" mechanics.

Effect of 850 nm LED irradiation on the alignment of crowded mandibular anterior teeth: a randomized controlled clinical trial.
Clin Oral Investig

Department of Orthodontics, Faculty of Dentistry, Kurdistan University of Medical Sciences, Sanandaj, Iran.
Introduction: This study aims to determine if intraoral 850 nm LED irradiation could reduce the duration of lower anterior crowding alignment.
Methods: In a parallel-designed, randomized controlled clinical trial 60 patients with 2 to 6 mm of lower incisor crowding who need non-extraction treatment, were randomly assigned to the intervention and control groups by block randomization (36 females, 24 males, mean age: 19.93 ± 3.
Rotations of teeth-a systematic review.
Front Oral Health
December 2024
Sri Ramachandra Medical College and Research Institute, Sri Ramachandra Institute of Higher Education and Research, Chennai, India.
Background: Rotations are frequently evaluated through various assessment methods of crowding and arch dimension, with relatively few studies discussing the extent or direction of rotations and even fewer addressing the reliability of such assessments. This systematic review aims to comprehensively analyze existing classification systems for rotated teeth and assess rotation in anterior and posterior teeth, its clinical applicability, and its impact on retention and relapse.
Search Methods: Two investigators conducted a comprehensive search in six databases, namely, PubMed, Scopus, Ovid, LILACS, Web of Science, and Cochrane CENTRAL, up to 28 March 2024.
Patient-Reported Outcomes of Orthodontic Treatment for Mild Crowding With Modified Aligner Appliance With Nickel-Titanium Springs: A Prospective Cohort Study.

Background and objectives A modified aligner appliance with nickel-titanium springs (MAA) is a relatively new appliance that has not received extensive attention in orthodontics. This study evaluated the patient-reported outcomes when orthodontic treatment was provided using a modified aligner appliance to treat mild lower incisor crowding. Materials and methods This prospective cohort study consisted of 42 patients (11 males and 31 females; mean age 21.

The impact of malocclusion on tooth loss over a 20-year period: Findings from the Population-Based Study of Health in Pomerania (SHIP).

Department of Prosthodontics, Gerodontology and Dental Materials, University Medicine Greifswald, Germany.
Objective: Research is lacking examining the effect of malocclusion on tooth loss. The aim of this study was to analyze the possible impact of moderate and severe malocclusions on tooth loss over the course of twenty years.
Material And Methods: Of 1269 subjects aged between 25 and 49 years with at least 20 teeth of the population-based Study of Health in Pomerania in Germany, malocclusions were initially assessed according to a German orthodontic index of treatment priority between 1997 and 2001.
