Atorvastatin inhibits osteoclastogenesis and arrests tooth movement.

Am J Orthod Dentofacial Orthop 2018 Jun;153(6):872-882

Department of Oral Biology, School of Dentistry, Federal University of Rio Grande do Sul, Porto Alegre, Rio Grande do Sul, Brazil. Electronic address:

Introduction: In addition to their cholesterol-lowering effects, the statin class of drugs appears to enhance osteogenesis and suppress bone resorption, which could be a clinical concern during orthodontic treatment. In this animal study, we aimed to determine whether atorvastatin (ATV) affects orthodontic tooth movement (OTM) through osteoclast inhibition. Furthermore, we analyzed the potential adverse effects of ATV on long-bone turnover and endochondral ossification. Read More

Using a single cone-beam computed tomography scan to obtain full occlusal details, with the mandible in centric relation and maximum intercuspation.

Am J Orthod Dentofacial Orthop 2018 May;153(5):741-746

Department of Orthodontics and Dentofacial Orthopaedics, Faculty of Oral and Dental Medicine, Cairo University, Cairo, Egypt.

Introduction: One obstacle with the implementation of digital technology in orthodontics is the acquisition of occlusal details while maintaining the mandible in the full interdigitation position. With 1 cone-beam computed tomography (CBCT) scan of the patient and 1 digital scan of the patient's dental models in occlusion, it might be possible to obtain full occlusal details and generate 2 volumes, with the mandible in centric relation and maximum intercuspation positions. The purpose of this article was to describe the technique. Read More

Orthodontic treatment of a patient with maxillary lateral incisors with dens invaginatus: 6-year follow-up.

Am J Orthod Dentofacial Orthop 2018 May;153(5):730-740

Department of Orthodontics, School of Dentistry, Saint Louis University, St Louis, Mo.

Introduction: Dens invaginatus is an anomaly of dental development in which calcified tissues, such as enamel and dentin, are invaginated into the pulp cavity. This morphologic alteration is more frequent in maxillary permanent lateral incisors and makes them more susceptible to carious lesions and pulp alterations.

Methods: This case report describes a patient with maxillary lateral incisors affected by dens invaginatus. Read More

Precision and reliability of Dolphin 3-dimensional voxel-based superimposition.

Am J Orthod Dentofacial Orthop 2018 Apr;153(4):599-606

Department of Orthodontics, School of Dental Medicine, Case Western Reserve University, Cleveland, Ohio.

Introduction: Superimposition of 2 cone-beam computed tomography images is possible by using landmarks, surfaces, or density information (voxel-based). Voxel-based superimposition is automated and uses the most image content, providing accurate results. Until recently, this superimposition was extremely laborious, but a user-friendly voxel-based superimposition has recently been introduced. Read More

Expanding torque possibilities: A skeletally anchored torqued cantilever for uprighting "kissing molars".

Am J Orthod Dentofacial Orthop 2018 Apr;153(4):588-598

Department of Periodontics, Faculty of Dentistry, Federal University of Rio Grande do Sul, Porto Alegre, Rio Grande do Sul, Brazil.

Several uprighting mechanics and devices have been used for repositioning tipped molars. "Kissing molars" (KMs) are an uncommon tooth impaction involving 2 severely tipped mandibular molars with their occlusal surfaces positioned crown to crown, with the roots pointing in opposite directions. Orthodontic uprighting of KMs has not been a usual treatment protocol, and it can be a challenging task due to the severe tipping and double impaction, requiring efficient and well-controlled uprighting mechanics.

Achieving ideal results when treating a difficult malocclusion is a challenge that orthodontists frequently encounter. Maintaining those results is sometimes more challenging than the correction itself. As specialists in orthodontics, we should be able to apply bone physiology concepts during the diagnosis and treatment planning process and predict how bone will react after biomechanical stimuli.
