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.

Guided Corticopuncture Associated with Microimplant-Assisted Rapid Palatal Expansion (MARPE): Planning Variables 

This study analyzed the planning of guided corticopuncture (suture weakening associated with microimplant-assisted rapid palatal expansion) in 171 patients to understand the variables that define and limit this type of treatment.

 

Diagnosis and Treatment of Maxillo-Mandibular Retrusion

Having noted that for some that the nighttime problems of many patients are mainly eliminated with a mandibular advancement appliance, which is then removed in the waking hours. Therefore, it seemed very logical that the mandible was retruded ; and, since the “daytime occlusion” was restored with removal of the appliance, it seemed apparent that the maxilla must also be retruded.  Therefore, by repositioning the maxilla properly, the mandible can then be retained in the relation which restored a competent airway; and, life-time night-time mandibular advancement appliances would not be necessary.

 

Esthetic-Functional Interceptive Treatment in a Patient with Dental Agenesis and Trauma: Case Report

Tooth loss is one of the factors that most frequently leads guardians seeking pediatric dentistry treatment. The aim of this study was to report a clinical case of dental agenesis with dental trauma in the deciduous dentition, its clinical and psychosocial repercussions and the treatment performed. A five-year-old girl was diagnosed with agenesis of tooth 52, trauma to tooth 51 and maxillary atresia. In an orthodontic approach, the treatment plan consisted of constructing a Haas-type expander associated with an esthetic-functional space maintaining device. The esthetic functional interceptive treatment made it possible to improve the format of the arch, functions of respiration, speech and the esthetics of the smile.
