International Journal of Orthodontics

The International Journal of Orthodontics (IJO) is a quarterly peer-reviewed clinical journal published by the International Association for Orthodontics (IAO). It has been continuously published since 2002 and is the successor of the Journal of General Orthodontics.

The IJO features original scientific and clinical articles on orthodontics, plus an editorial, practice tips and office management hints. The purpose of the IJO is to serve as an educational tool, as well as to present innovative treatment mechanisms as they are developed.

All archived issues of the IJO can be found through the search function below and are also part of the Dr. Joseph M. Sim Library.  The articles are indexed.  They can easily be searched by author, title, or subject matter.  Research a specific topic, methodology, technique, or technology from it origins over the last forty years.

Who Is at Fault, the Doctor or the Patient?

This report details specific clinical, patient, and practice management techniques and risk management principles relating to the duties and obligations owed under the doctor-patient relationship by both the patient to the doctor, and the doctor to the patient. The reader is asked to decide which party was primarily responsible for the injury the patient sustained.

Interceptive Orthodontic Management of a Child with Severe Hypomineralization in Primary Molars and Canines

Hypomineralized second primary molars (HSPM) are characterized by a qualitative defect in enamel development occurring during the mineralization and maturation phases of amelogenesis.  HSPM is prevalent but often underdiagnosed, particularly by orthodontists, and a multidisciplinary approach is essential to establish an appropriate treatment plan, especially when malocclusions are already present at an early age. Numerous risk factors (environmental and systemic) may be associated with hypomineralization, as well as with malocclusions (extrinsic and intrinsic factors and deleterious oral habits), in addition to genetic/hereditary influences. This case report describes an 8-year-old female patient in the mixed dentition stage presenting with severe HSPM and canines, molar-incisor hypomineralization (MIH), maxillary constriction, anterior open bite, and Class II malocclusion associated with mandibular retrognathism.  Clinical and radiographic  examinations revealed extensive enamel deterioration of the affected primary molars and canines, occlusal disharmony, and vertical growth tendency. A family history suggestive of hereditary involvement was  lso identified. After interceptive orthodontic treatment, the patient  xhibited preserved clinical crown integrity of teeth affected by MIH, satisfactory occlusion, improved facial profile, and a harmonious smile. This case highlights the importance of early diagnosis of DDEs and the role of a multidisciplinary interceptive approach in preventing functional deterioration, minimizing structural damage, and improving long-term occlusal and esthetic outcomes.

Referrals Are Relationships Made Visible

Referrals are not a marketing gimmick.  Referrals are not a punch card or a sign at the front desk. Referrals are not something you “get” by squeezing in one more awkward ask on the way out the door.

Standard of Care Versus State of the Art

A comparative analysis of orthodontic standard of care versus orthodontic state of the art.

Orthodontically straight teeth compared to orthodontically straight teeth when considering dental function and the TMJ. As the level of orthodontic treatment progresses from standard of care to state of the art, the health of the TMJ and the dental occlusion come into closer focus. Standard of care provides the patient with orthodontically straight teeth that function and a full smile.  The state of the art provides the patient with orthodontically straight teeth, a functional dentition that works in a particular way, a full smile, and particular attention to the TMJ’s condyle-disc position and its function.

Mulligan Mechanics III:
Mulligan Intrusion Arch

The Mulligan Intrusion arch is a two-couple intrusion arch wire used for control of anterior deep overbite. It is commonly made with round wire (a .020 or a .018 SS), attached to the teeth only at the molars and the incisors and is activated for incisor intrusion by a molar tip-back (off-center, gable) bend. Dr. Mulligan used a .020 ss arch wire; however, the author prefers a .018 SS arch wire – as there is less friction and biding.

Accelerated Orthodontics:
Can We Move Teeth Faster in Adults?

This review compares two minimally invasive approaches for accelerating orthodontic tooth movement in adults — microosteoperforations (MOPs) and platelet concentrates (PRP/PRF)  with emphasis on the rate of canine retraction/tooth movement, patient-reported comfort and pain, and treatment-related adverse effects.

Overall, MOPs demonstrated greater acceleration, whereas PRP/PRF was generally associated with less pain and discomfort.  Protocols and outcome measures varied across studies, limiting direct comparison and highlighting the need for additional headto- head trials.

Keywords: accelerated tooth movement , microosteoperforation, PRP/PRF in orthodontics, pain perception in OMT, side effects in OMT

IAO’s Journal Library

The International Association for Orthodontics (IAO) has had three scholarly Journals during the association’s existence. The first was the Journal of General Orthodontics. This was followed by the Functional Orthodontist. Currently, the IAO releases the International Journal of Orthodontics on a quarterly basis. This is almost 40 years worth of journals. The total collection is well over 200 issues.

Every issue of these three journals is archived in the IAO’s Journal Library. Each one has also been indexed. This means that users can search through every issue by author, title, topic, even a common phrase. The search tool will return every article where the term was found, what issue it was in, and an abstract. The user can then click the link to access that specific article, or view the entire journal.

The IAO’s Journal Library is a perfect tool for researchers. Authors can find the original studies on almost 40 years of orthodontic techniques, advancements, and technology. Quote the original source on the topic being researched. Comb through every issue of the International Journal of Orthodontics, Functional Orthodontist, and General Journal of Orthodontics for your subject at hand in seconds.

This library is continually expanding. Once an author has finished an article, it can be submitted to the International Journal of Orthodontics for publication. The journal is provided to thousands of dentists practicing orthodontics across the world. Your research could influence practices all over the globe.

IAO members come to this organization in search of knowledge. The International Journal of Orthodontics is a key source of information. It helps members stay on top of the latest advancements, trends, and techniques. Any research published will be archived as part of the IAO’s Journal Library for years to come. A decade from now, another author may be looking up research provided in an International Journal of Orthodontics article. They will be able to easily search for the information as the article will be indexed. Said research can help propel advancements in the subject’s area for years to come.

The IAO is built on the principle of promoting the exchange of knowledge to better the practice of orthodontics. The IAO Journal Library is a principal contributor to this ideal. It is a perfect tool for those looking to advance their knowledge, perform in-depth research, or publish important findings.
