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 ...
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 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 ...
Measurement of tooth extraction forces in upper incisors
Collegium antropologicum
A new method, applied for the first time in this research, was used for measurement of tooth extraction forces. The research has been done in a group of 50 examinees to whom the tooth extraction has been done with lower premolar forceps - forceps "13" and in the control group of 54 examinees in whom the tooth extraction has been done with upper incisive forceps - forceps "1". The measurement instrument registered the extraction forces values in both types of forceps. There was no difference in any parameters in these two groups except in used pressure. While using the forceps "13", a significantly lower tooth extraction force was measured than the force measured while using the forceps "1" (p < 0.001). This means that in clinical work we can already apply noticeably less force using the lower premolar forceps for the extraction of the upper incisors (in the moments of rotation up to 70%). These results are meaningful, because they lead to b...

The aim of this in vitro study was to evaluate the stripping achieved on different teeth (incisors, canines, and premolars) by two grades of abrasive strips used for the first and tenth time. Our second aim was to test the efficacy of these strips by calculating the time necessary to perform interproximal reductions of 0.10, 0.20, and 0.30 mm. Four models were constructed using extracted teeth affixed in wax. The upper and lower arches were set on plaster bases and fixed in wax, carefully creating contact points. All model mouths were treated with artificial saliva (Oral Balance®) in order to simulate the biological conditions in the oral cavity. We then tested specific air-rotor strips of different grades and degrees of wear (15-µm-grain and 25-µm-grain Orthofile® strips). Afterwards the teeth from all samples were cut lengthwise in half, and each mesial and distal portion was gold-plated and observed under SEM at incremental magnification (30, 60, and 100 µm). The 25-µm-grain stri...
Extraction Planning in Orthodontics
The Journal of Contemporary Dental Practice, 2018
Introduction: Planning extraction of teeth for orthodontic treatment is one of the challenging factors for successful functional and esthetic orthodontic results and for the longterm stability. Aim: The aim of this study is to document possible extraction guidelines for planning of orthodontic treatment for space deficiency cases related to excess tooth material. Results: The guidelines are written as patterns to facilitate the decision of extraction of teeth for class I, class II division 1, class II division 2, and class III malocclusions, for crowding, overjet reduction, or correcting the buccal segment relationship. The decision for extraction of teeth for orthodontic treatment is enforced by the oral hygiene, carious teeth, periodontal involvement, impacted teeth, supernumeraries, hypodontia, or for orthognathic purposes. Also, planning the decision for accurate extraction pattern is the main factor in the success of the orthodontic treatment and for the long-term stability of the results. Conclusion: Orthodontic tooth extraction should always be planned with consideration of the width and length of the face, the oral hygiene, carious activity, periodontal involvement, malformed crowns, length and health of the root of the teeth, prognosis of impacted teeth, supernumeraries, and hypodontia. Clinical significance: Accurate diagnosis and treatment planning following orthodontic extraction guidelines lead to a longterm stability of the corrected results.
Iatrogenic displacement of high-speed bur during third molar removal
BMJ Case Reports, 2017
Surgical removal of impacted mandibular third molar is a routine procedure in oral surgery. Various iatrogenic complications related to the procedure has been discussed well in the literatures before. Some of these complications are related to the wrong usage of instruments and techniques. Here we discuss a rare complication on a 42-year-old male, related to the use of high-speed handpiece drill in mandibular third molar removal in a general dental office setting. He was referred when a high speed tungsten carbide bur was accidentally broken and displaced into the mandibular bone during surgical procedure. It is not common to use a high-speed handpiece in impacted third molar removal. This iatrogenic complication could have been totally avoided with the use of proper equipment and technique; therefore raising awareness regarding wrong usage of instrument is vital to avoid similar incidents in the future. © 2017 BMJ Publishing Group Ltd.
Advances in Methods of Atraumatic Tooth Removal: An Update
International Journal of Preventive and Clinical Dental Research, 2017
Dental extraction, once considered as punishment, has now become one of the finest works in dental surgery. Traumatizing the entire being with this deed was the idea 200 years ago, on the contrary today we try completing the procedure without the need of gingival reflection. This paradigm shift gave birth to atraumatic extraction techniques (AETs), which intend the removal of tooth or tooth root, while maintaining a harmonious relation with gingiva, bone, and other surrounding hard and soft tissue structures. Instruments, such as Benex vertical extractor, powered periotome, piezosurgery, sonosurgery, physics forceps, Ogram system, Easy X-Trac system and techniques, such as the orthodontic extrusion technique and rubber band extraction help in achieving this noble goal. The main benefits of AET are immediate implant placement, faster healing, and reduced need for bone grafting and soft tissue augmentation, leading to faster prosthetic rehabilitation in a limited time span. This review is an insight into each technique and instrument highlighting its advantages and drawbacks to instigate awareness and also allow for the better understanding among maxillofacial and dental professionals.
