Tunnel Traction Procedure for Deeply Impacted Canines and Resorbed Lateral Incisors
Volume 49 : Number 12 : Page 784 : Dec 2015
Three-dimensional radiographic studies have found root resorption in 38% of the lateral incisors and 23% of the central incisors associated with impacted canines. Although such damage can occur even when canines erupt normally, the key to success in treating an impacted canine is to achieve correct positioning in the dental arch without causing periodontal defects. A combined surgical-orthodontic approach called the tunnel traction procedure enables physiological eruption of a deeply impacted upper canine while preserving long-term periodontal health. Introduced by Crescini and colleagues, the technique is based on the concept of infracrestal guided eruption. It is recommended for use in cases where the corresponding deciduous teeth provide sufficient space for eruption of the impacted canines.

Correction of Single-Tooth Crossbite
Volume 29 : Number 4 : Page 0 : Apr 1995
Correction of posterior or anterior single-tooth crossbite, although it involves a limited portion of the dental arch, can be difficult. The tooth in crossbite must be intruded and moved either lingua...

Nonsurgical Orthodontic Treatment of Adolescent Patients with Severe Jaw Deformities
Volume 52 : Number 9 : Page 477 : Sep 2018
Individuals with jaw deformities dating back to childhood generally require long and difficult orthodontic treatment. Drs. Demura, Hasumoto, and Demura describe a relatively short nonsurgical approach, involving maxillary expansion and intermaxillary cross-elastics, that can be successful in growing patients.

The Use of Cone-Beam Computed Tomography in the Diagnosis and Treatment of Severely Ectopic Teeth
Volume 41 : Number 11 : Page 701 : Nov 2007
In this month's Cutting Edge column, Dr. William Mehan exposes a diagnostic chasm that we have all fallen into on occasion. We use lateral headfilms, frontal headfilms, and panorexes--all two-dimensio...

Controlling the Vertical Dimension
Volume 51 : Number 7 : Page 375 : Jul 2017
The vertical dimension of the face, or facial height, is one of the more esoteric concepts in dentistry. The online Medical Dictionary defines it as "the linear dimension in the midline from the hairline to menton." Anterior facial height is rather self-evidently described as "the sum of upper and lower facial heights, the lower limit of the latter variously defined as the pogonion, gnathion, or menton. Posterior facial height is often measured from the gonion to the condylare, sella, or center of face point." The occlusal correlate of facial height is the vertical dimension of occlusion (VDO).

Rapid Dentoalveolar Expansion Technique
Volume 11 : Number 1 : Page 47 : Jan 1977
Ever since Korkhaus came to the United States in 1956 and presented his method of splitting the palate in maxillary deficiency cases, this form of treatment has burgeoned in popularity with an impetus...

Accelerated Extraction Treatment with the Invisalign System and Photobiomodulation
Volume 54 : Number 3 : Page 151 : Mar 2020
Drs. Ojima, Dan, Watanabe, Kumagai, and Nanda demonstrate the capability of low-level laser therapy (OrthoPulse) to shorten difficult extraction treatment with clear aligners. The case of an adult female with severe crowding is presented to illustrate their technique.

Volume 57 : Number 9 : Page 512 : Sep 2023
The posterior lingual cortex of the mandible has been considered the anatomical limit for orthodontic distalization. Drs. Kim and Park show a case in which CBCT images indicate long-term alveolar bone recovery after cortical dehiscence caused by substantial distal movement.

Treatment of Bimaxillary Protrusion Using Fiber-Reinforced Composite
Volume 41 : Number 1 : Page 0 : Jan 2007
Treatment of bimaxillary dentoalveolar protrusion often involves the extraction of four first premolars.1 Since these patients often have Class I molar relationships, the objective is usually to reduc...
