Primary failure of eruption and PTH1R : The importance of a genetic diagnosis for orthodontic treatment planning
Introduction Primary failure of eruption (PFE) is characterized by nonsyndromic eruption failure of permanent teeth in the absence of mechanical obstruction. Recent studies support that this dental phenotype is inherited…

Editor’s Summary and Q&A
Introduction Orthodontic space opening during adolescence is a common treatment for congenitally missing maxillary lateral incisors. Because of continued facial growth and compensatory tooth eruption, several years can elapse between…
Standards of care
The October issue of the Journal had much to say about establishing standards of care. (Riolo ML, Vaden JL. Standard of care: why is it necessary? Am J Orthod Dentofacial…
Postorthodontic root approximation after opening space for maxillary lateral incisor implants
Introduction Orthodontic space opening during adolescence is a common treatment for congenitally missing maxillary lateral incisors. Because of continued facial growth and compensatory tooth eruption, several years can elapse between…
Validity of 3-dimensional reconstruction and simulation of mandibular movement and occlusal contact
I read with interest the article on 4-dimensional analysis of stomatognathtic function (Terajima M, Endo M, Aoki Y, Yuuda K, Hayasaki H, Goto TK, et al. Four-dimensional analysis of stomatognathtic function….
Authors’ response
The interesting, legally crafted letter from Dr Burns elicits the following question. If you require a heart bypass operation, a hip replacement, or a colonoscopy (ugh!), would you prefer to…
Authors’ response
We thank Dr Hudson for his letter about our recent article. We agree wholeheartedly that we as a specialty have concentrated far too long on issues that divide us, rather…
Authors’ response
We thank Dr Roehm for his interest in our article. He provided a witty anecdote. Nonetheless, his comments are more theatrical than substantive. He furnished no research or evidence supporting…
Gnathology lessons from a 1969 Oldsmobile engine
In 1972, my father and I had our heads under the open hood of a 1969 Oldsmobile 442, listening to an idling 500-horsepower 455-cubic inch engine clunk and clatter. We…
Need and demand for orthodontic services: The final report
The Golden Age of orthodontics occurred in the 1950s and 1960s, when practitioners had more patients seeking care than they could start; some even had waiting lists as long as…
After 50 years in practice, the evidence is convincing
I have been in active orthodontic practice for nearly 50 years. During this time, I have seen many different theories for “orthodontic gnathology” and TMD diagnosis and treatment, with each guru…
Combined maxillary and mandibular midline and mandibular ramus distraction osteogenesis for treatment of a Class II patient with implants as orthodontic anchorage
This case report describes the treatment of a woman with severe mandibular retrusion and maxillomandibular transverse deficiency. Her malocclusion was characterized by a large overjet, a deep overbite, and a…
Treatment of a severe arch-length deficiency with anteroposterior and transverse expansion: Long-term stability
This article describes the nonextraction treatment of a girl in the late mixed dentition with a severe arch-length deficiency. Rapid maxillary expansion and molar distalization were combined with a lip…
Three-dimensional comparison of facial morphology in white populations in Budapest, Hungary, and Houston, Texas
Introduction The aim of this study was to assess the use of 3-dimensional facial averages in determining facial morphologic differences in 2 white population groups. Methods Three-dimensional images were obtained…
