Interproximal reduction in orthodontics: why, where, how much to remove?
Australasian Orthodontic Journal, 2021
Interproximal reduction (IPR) is the deliberate removal of part of the dental enamel from the interproximal contact areas, which decreases the mesiodistal width of a tooth. This enamel may be removed for various reasons, but most commonly to create space during orthodontic treatment or to correct tooth-size discrepancies. Several authors have also encouraged its use as a method by which post-orthodontic stability might be enhanced, particularly in the lower anterior region. With the increased use of removable aligners for orthodontic treatment in which non-extraction therapy is often advocated, the use of IPR becomes a valuable tool to relieve crowding without over-expanding the dental arches. It is possible that inaccurate IPR could result in the over-reduction of enamel, the creation of ledges and notches in the proximal surfaces, increased tooth sensitivity or damage to the surrounding soft tissues. However, carefully conducted IPR performed within the recommended guidelines may ...
Interproximal Reduction Facilitating Orthodontic Teeth Extraction
Cureus Part of Springer Nature Group, 2023
Extractions are routinely performed in orthodontics to gain space for teeth alignment. Crowded, malaligned, and overlapped teeth make it difficult for the dental surgeon to engage the beaks of the extraction forceps on the concerned tooth for extraction. An improper grip often leads to complications of instrument slippage, crown fracture, and more commonly, luxation of adjacent teeth. This article aims to help with atraumatic orthodontic extractions and reduce such complications. This case report examines an interproximal reduction technique using standard grit, taper, flat-end diamond bur (Mani TF-20, ISO 171/014, Mani, Inc., Tochigi, Japan) for the tooth to be extracted to create enough space for proper placement of the forceps and to prevent injury to adjacent structures. It can be useful for orthodontic extractions or other cases of tooth extractions with inadequate access.
Interproximal reduction of teeth: Differences in perspective between orthodontists and dentists
The Angle Orthodontist, 2014
Objective: To determine if interproximal reduction of teeth (IPR) is perceived differently by orthodontists and general dentists. Materials and Methods: A Web-based survey containing statements about IPR was developed and randomly distributed to orthodontists and general dentists. Results: The majority of orthodontists and general dentists strongly agreed that IPR is a minimally invasive procedure that poses little risk for the development of interproximal decay. However, general dentists were more likely to perform post-IPR polishing and to apply topical fluoride than are orthodontists (P < .0001). A greater percentage of orthodontists strongly believed that the esthetic and occlusal benefits of IPR outweigh the potential risk of tooth decay when IPR was performed (P < .0001). A greater percentage of general dentists were hesitant to perform IPR, despite research supporting that IPR has little negative effect on the health of teeth. Conclusions: The results of this study ...
Interproximal enamel reduction as a part of orthodontic treatment
Stomatologija / issued by public institution "Odontologijos studija" ... [et al.], 2014
Interproximal enamel reduction is a part of orthodontic treatment for gaining a modest amount of space in the treatment of crowding. Today interproximal enamel reduction has become a viable alternative to the extraction of permanent teeth, and helps to adjust the Bolton Index discrepancy. The aim of the study is to evaluate various interproximal enamel reduction techniques, its indications, contraindications and complications presented in recent scientific studies. Papers published in English language between 2003 and 2012 were searched in PubMed, ScienceDirect and The Cochrane Library databases, as well as the Web search Google Scholar. Initial searches were made to find peer-reviewed systematic reviews, meta-analyses, literature reviews, clinical trials, which analysed at least one interproximal enamel reduction method. 31 published data fulfilled the inclusion criteria. According to the study, abrasive metal strips, diamond-coated stripping disks, and air-rotor stripping are the ...
Crowded Teeth Elimination: Proportional and Controlled Narrowing of Upper Incisors
Journal of Dental Science Research Reviews & Reports
Anterior teeth crowding when the total width of the teeth is greater than the length of the anterior sextant of the dentition, is the most common dentomaxillary anomaly. In order to eliminate crowding of the anterior teeth the reduction of the proximal enamel is widely used to reduce the width of the teeth and improve conditions for subsequent orthodontic treatment [1-6]. Based on the calculation of the anterior sextant of the dentition using the «golden coefficient», it is possible to determine the optimal width of the central and lateral incisors for the anterior sextants of a given length, when all the anterior teeth will be symmetrical and proportional when they are in the correct position [7-10]. For the proportional lack of place distribution for all frontal teeth, it has been proposed to make the enamel reduction of every tooth from both proximal surfaces according to the calculation, with maintaining of contact surfaces and contact point position. Then orthodontic treatment ...

Background: Interproximal enamel reduction is a valuable procedure in orthodontics used in several conditions, however, not knowing the average value of proximal enamel thickness might lead to excess enamel removal and consequently to adverse effects. Objective: The objective of this systematic review is to expose the average proximal enamel thicknesses found in the literature, and the differences that might be found between different ethnicities and age groups. Search Methods: 5 electronic databases were used to perform the search. Representative keywords comprised of “enamel”, “thickness”, “orthodontics” “proximal thickness” and “quantification”; different combination of these keywords with truncation, and medical subject headings (MESH) were used. Selection Criteria: In vitro and in vivo studies, where the quantification of the proximal enamel thickness of the mesial and distal sides were evaluated independently. Data Collection and Analysis: The PICO model was used to evaluate a...

Crowding is one of the most common findings in orthodontic patients. This case report describes the correction of anterior crowding with interproximal reduction (IPR). The case is that of a 24-year-old female patient who consulted for irregularly placed anterior teeth. Fixed appliances were placed followed by IPR. Treatment time was 18 months. Class I molar relation was maintained, with normal overjet and overbite. IPR is effective for treatment of patients with Class I malocclusion with anterior moderate crowding.

Background The aim of the study was to compare the amount of interproximal enamel reduction (IPR) provided on ClinCheck software with the amount of IPR carried out by the orthodontist during treatment with clear aligners. Methods 30 subjects (14 males, 16 females; mean age of 24.53 ± 13.41 years) randomly recruited from the Invisalign account of the Department of Orthodontics at the University of Rome “Tor Vergata” from November 2018 to October 2019, were collected according to the following inclusion criteria: mild to moderate dento-alveolar discrepancy (1.5–6.5 mm); Class I canine and molar relationship; full permanent dentition (excluding third molars); both arches treated only using Comprehensive Package by Invisalign system; treatment plan including IPR. Pre- (T0) and post-treatment (T1) digital models (.stl files), created from an iTero scan, were collected from all selected patients. The OrthoCAD digital software was used to measure tooth mesiodistal width in upper and lower ...
Nonextraction methods for creating space in orthodontic therapy
Introduction: Molar distalization is an alternative treatment method in dento-maxillary anomalies, to avoid extraction especially in low angle cases. The orthodontic literature indicates that upper molar distalization is a tipping movement, combined with mesiobuccal rotation and buccally-crown torque. The aim of the study was to analyze the advantages to create space during upper first molar distalization movement, by using different devices. We used this method in skeletal Angle Class II, dental Class II/2 malocclusion with crowding and low profile. Methodology: The study consisted of a retrospective statistical analysis on 435 patients aged 11-13 years treated with fixed appliances (straight wire technique), between 2009- 2012. The patients were divided in two groups: group A (83) who worn distalization devices and group B (352) who did not. Group B was divided in: B1 (278) with other nonextraction appliances and B2 (74) with extraction during orthodontic treatment. Results: Upper molar distalization was successful in 45% of the cases, the values of the space being: 2,13- 2,33 mm, by tipping movement. Bodily distal upper molar movement was successfully obtained only when the rotational axis is at infinite and the compressive stress is homogeneously distributed in the periodontal ligament. The success rate depended on: eruption of the second molar, overjet and overbite size. Conclusions: 1. Molar distalization is a challenge in orthodontic treatment and is indicated for Angle Class II, crowding and low angle (extraction makes the profile worse). 2. Molar distalization depends on the position of the second molar and this technique is not singular, but associated with multibracket appliance . Key words: distalization, second molar, class II, extraction, fixed appliances.
