April Suppl 2014; 145(4):S12.
A patient's trust
Your new patient is eager to start treatment, but only if you can guarantee completion before her wedding, a mere 11 months away. You recently completed a course in accelerated tooth movement, and you are eager to put what you've learned into practice. You already place your own temporary anchorage devices, perform your own fiberotomies, and extract deciduous teeth with confidence and ease. The lateral corticotomy and associated bone grafting procedures seem straight-forward and logical -- why not try it yourself? You certainly want to help this eager patient. 
But is it fair to proceed without telling the patient that although you are confident you can perform the technique, you have no actual experience? What is the right course of action? Read Peter Greco's thoughtful comments in the April Supplement.

Comparison of virtual and manual tooth setups with digital and plaster models in extraction cases 
By  Joon Im, Jung-Yul Cha, Kee-Joon Lee, Hyung-Seog Yu, Chung-Ju Hwang
The aim of this study in the April 2014 issue was to compare the virtual and manual tooth setups with digital and plaster models. The authors applied the American Board of Orthodontics objective grading system to various occlusal parameters and found that while some measurements were the same, delicate adjustments in proximal and occlusal contacts are required. Watch the video then look for the full text of the article in the April issue.

Orthodontic retraction of autotransplanted premolar to replace ankylosed maxillary incisor with replacement resorption
Yoon-Jeong Choi,  Sujung Shin, Kyung-Ho Kim, and Chooryung J. Chung
Seoul, Korea

This young man’s maxillary left central incisor had been knocked out when he was a boy. Although it had been replanted, it failed to erupt normally and now showed signs of ankylosis. He had moderate crowding in both jaws and bialveolar protrusion. How would you treat this patient?

This month, the Journal is pleased to honor the authors of 4 award-winning articles published in 2013. You can read about the Dewel, Watson, Turpin, and CDABO awards in recent posts on this Blog. Selecting the winners for these awards was difficult because so many other great research studies were published last year. Read David Turpin’s April editorial to learn about 3 other great articles you might have overlooked.
Lingual retainersbonded without liquid resin: A 5-year follow-up study,” by Alexander T. H. Tang et al (Am J Orthod Dentofacial Orthop 2013;143;101-4 ).

April 2014 Supplement; 145:4S
Surgical techniques to shorten treatment time

Each April, the AJO-DO publishes a Supplement and Product Resource Guide.
Articles in the Supplement are grouped around a theme; this year's theme is  surgical techniques to shorten treatment time. In the lead-off article in the 2014 Supplement, “Surgically facilitated orthodontic treatment: A systematic review,” Hoogeveen, Jansma, and Ren, from University Medical Center Groningen, The Netherlands, provide the first systematic review of this timely topic.   
   They identified 18 published studies that met their inclusion criteria. Seven were clinical trials with small sample sizes. The aims of their review were to answer the following questions: (1) Does surgically facilitated treatment significantly increase the velocity of tooth movement and shorten treatment duration, compared with conventional orthodontics? (2) Is there a difference in the incidence of tooth vitality loss, periodontial problems, and root resorption? (3) Do the designs of the cortical cuts and the gingival flaps influence the efficiency of tooth movement and the incidence of complications?
   Go online to see the April Supplement today, and watch your mailbox for the paper copies of the April regular issue and Supplement to arrive soon. 
   The smiling patient on the cover is Mayuri Rataul, who was treated orthodontically at SDM College of Dental Sciences, Dharwad, India, by Drs Tanuja Ajit Deshpande, Sangamesh B, Roopak Naik, and Sanjay V Ganeshkar.

April 2014; 145(4)
The April 2014 issue of the AJO-DO is now online
On the cover: Three-dimensional digital models are now often used in orthodontic diagnosis and treatment planning, including the production of setups to visualize the results of various procedures. But the standards and characteristics of virtual setups using 3D models have not been widely explored. Im et al compared the virtual and manual tooth setups with digital and plaster models for 10 patients whose treatment was planned to include extractions. 
The smiling patient on the cover is Luke Tassopoulos,
who was treated orthodontically by Timothy Shaughnessy from Suwanee, Georgia.
