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.

Winter IJO Abstract


Hippocrates wrote circa 410 BCE that “The doctor must be able to tell the antecedents, know the present, and foretell the future – must mediate these things, and have two special objects in view with regard to disease, namely to do good or to do no harm. The art consists in three things – the disease, the patient, and the doctor.  The doctor is the servant of the art, and the patient must combat the disease along with the doctor.” the teaching, mentoring, and support of general dentist members who choose to provide orthodontic services to their patients.

Hippocrates wrote circa 410 BCE that “The doctor must be able to tell the antecedents, know the present, and foretell the future – must mediate these things, and have two special objects in view with regard to disease, namely to do good or to do no harm. The art consists in three things – the disease, the patient, and the doctor.  The doctor is the servant of the art, and the patient must combat the disease along with the doctor.”

The Eyelet Part 2

Treatment of Growing Male Patient with Skeletal Class II Jaw Bases With Retrognathic Mandible And Class II Division 1 Malocclusion (PRE-ADOLESCENT) USING TWIN BLOCK APPLIANCE: A CASE REPORT

Among all the malocclusions Class II malocclusion is one of the most common problems affecting growing as well as non-growing individuals around the globe. About one-third of the patients coming for orthodontic treatment have this type of malocclusion. Twin block appliance is most commonly used in Class II Div I malocclusion cases as it is less bulky as compared to other monobloc appliances. Twin block appliance is effective for correction of Class II malocclusion as well as mandibular retrognathism.  Correction of problems through this appliance is based on various factors such as selection of the case, age of the patient and patients’ compliance. This appliance is indicated in patients having retruded mandible with positive virtual treatment objective (VTO), it will enhance the growth of the mandible and improve the patients’ profile. The profile changes and treatment results were demonstrated. With proper case selection and good co-operation, we can obtain a significant result with the Twin block appliance.

Fixed Functional Appliance with Skeletal Anchorage System (FFA-SAS) – An Exemplary Comparative Review

Fixed functional appliances (FFAs) in conjunction with Skeletal anchorage devices have been proposed to enhance skeletal effects and reduce dentoalveolar effects like proclination of the lower incisors. In this exemplary review, we have discussed in detail about skeletal, Dentoalveolar, and Soft tissue effects when FFD is used with Skeletal anchorage.

Avoid This Common New Year Planning Mistake

We talk here about beginning with the end in mind and I will tell you I don’t think enough Doctors take it literally enough.

A Modified Fixed Twin Block

The conventional Twin Block appliance was modified for growth modification and correction of malocclusion in the growing skeletal Class II patients with non-compliant behaviour.  The modifications can be easily managed by the clinician at the same time being comfortable for the patient. This modified appliance was fabricated for a skeletal Class II patient and it delivered favourable results in short period of time, proving its efficiency and scope for further use.
