Here at JCO, we make it part of our mission to bring new ideas to the practice of orthodontics. Articles on temporary anchorage devices and cone-beam technology that would have come across as science fiction in the not-toodistant past are now commonplace in the orthodontic literature, particularly this journal. Many practitioners, including me, are always excited to try out new techniques, new appliances, and new developments in all areas of the specialty. We pride ourselves in being on the cutting edge - indeed, JCO has a regular department with just that name: "The Cutting Edge".
Protracted treatment is one of the greatest challenges in orthodontics. As treatment lengthens, the patient is increasingly exposed to oral-health risks including root resorption, caries, and periodontal disease. Patient satisfaction may also decline as treatment is extended. Uribe and colleagues, evaluating the perceptions of parents, patients, and orthodontists on the need to accelerate treatment, found that 55% of adolescent patients felt their treatment was too long. Seventy percent of the responding orthodontists said they would be interested in clinical procedures that would reduce treatment time. The invasiveness of each procedure was inversely related to acceptance of that treatment for both orthodontists and patients.
Many orthodontists have discovered the utility of a simple, vertically positioned square hole in an orthodontic bracket. The vertical slot, or V-slot, permits the simple addition of a variety of useful auxiliaries and biomechanical adjuncts. As Gianelly once said in a personal communication, "I don't understand why you wouldn't want a vertical slot in your bracket, whatever bracket you choose; it's free."
Identifying the optimal timing for any treatment involving growth modification is crucial to success.1 The cervical vertebrae, as seen on a lateral cephalogram, have proven to be a reliable indication...
Various cheek and lip retractors work well for taking frontal and buccal intraoral photographs, but tend to interfere with mirror placement when taking upper and lower occlusal photographs. The need for the patient to retract the lips with both hands makes photography difficult.
Space regaining is an important treatment modality for eruption guidance. Shalish and colleagues reported that space regaining and the removal of obstructions can facilitate spontaneous eruption of impacted premolars. Although several devices have been developed to regain space through molar distalization, these methods may result in anchorage loss, incisor proclination, and a slight increase in vertical facial dimension. Koutzoglou and Kostaki reported a relationship between rapid palatal expansion and the natural eruption of impacted canines, but maxillary expansion has also been related to a loss of height and thickness of buccal alveolar bone at the anchorage teeth.
Pain in the orofacial complex is one of dentistry's most vexing and mysterious diagnostic challenges. Basically ignored by medicine and orphaned by the dental specialties, oral and facial pain continues to plague millions of people. Whether or not you intend to diagnose and treat such patients, Bell's Oral and Facial Pain remains the essential text on the subject. Dr. Jeffrey Okeson, Professor and Chair of the Department of Oral Health Science and Director of the Orofacial Pain Program at the University of Kentucky, has dedicated the seventh edition of the book to its namesake - his mentor, teacher, and friend, Dr. Weldon E. Bell.
Aggressive periodontitis involves rapid periodontal destruction in otherwise healthy individuals - generally younger patients, though older individuals may also be affected. If it is not diagnosed early and treated appropriately, generalized aggressive periodontitis can lead to early tooth loss. The clinical appearance and pattern of destruction may vary; the most common complaints are recently noticed flaring, progressive spacing, and mobility of the anterior teeth. Such an occurrence not only affects the patient's function and esthetics, but can also be detrimental to self-esteem.
