There's No Perfect Malocclusion

ROBERT G. KEIM DDS, EdD, PhD

A number of years ago, when I was graduate program director in a large orthodontic department, I had the task of orienting a new clinical professor. He was a highly experienced and well-respected Tweed practitioner who had been recruited specifically to teach the Tweed technique.

Canine Bracket Guide for Substitution Cases

NEAL D. KRAVITZ DDS, MS, SHAWN MILLER DMD, MMedSc, AMIT PRAKASH BDS, MDS, JIJO C. EAPEN BDS, MDS

The most common error in maxillary canine-lateral incisor substitution cases is inadequate palatal torque of the relocated canine. This article examines the rationale for various bracket choices, including tip and torque prescriptions, as well as wire-bracket play and other factors that influence canine torque.

CHUNG HOW KAU BDS, MScD, MBA, PhD, MOrth, FDS, FFD Ortho, FICD, FAMS, KATELYN BOWMAN FEINBERG DMS, MS, TERPSITHEA CHRISTOU DDS, MS

This study was designed to evaluate the effectiveness of the Invisalign system in treating Class I and II patients with and without anterior open bite. The pretreatment difficulty of cases is compared with the post-treatment outcomes, as measured by the Peer Assessment Rating (PAR) and the Index of Complexity, Outcome, and Need (ICON).

Effects of Bisphosphonates on Orthodontic Treatment and the TMJ: A Systematic Review

BHUMIJA GUPTA BDS, MS, SHILPA SINGH BDS, ROSS H. TALLENTS DDS, EMILE ROSSOUW DDS

This review of 34 published articles was designed to help clinicians predict orthodontic treatment outcomes and condylar changes in patients who have taken bisphosphonates. Effects of the drug on bone turnover, tooth movement, root resorption, and endochondral growth of the condyles are examined, and clinical recommendations are made.

Extraction of Gingivally Retained Deciduous Teeth Using Orthodontic Elastics

CAMERON G. WALKER DDS, MS, PhD, ROY KING DDS

The authors provide a creative method for loosening a retained deciduous tooth by placing an orthodontic elastic around its cementoenamel junction. The deciduous tooth is simply “squeezed” loose from its gingival attachment in a few days, with no discomfort and minimal bleeding. This technique works for small or large retained teeth.

Physiological Drifting of Ectopic Canines

ARUN KUMAR DASARI BDS, MDS, M.S.V. KISHORE BDS, MDS, MOrtho RCS, KALADHAR REDDY AILENI BDS, MDS, DIBO, SANDEEP BATTULA BDS, MDS, CHINTAKUNTA REDDY PRATHIMA BDS, MDS, MADHUKAR REDDY RACHALA BDS, MDS, DIBO

If first premolars are extracted to make space for ectopic canines, rather than using loop or continuous-arch mechanics, the canines can be allowed to migrate naturally into the extraction sites. Two cases demonstrating this physiological drift are shown, and benefits of the approach are described.

He starts by providing a historical perspective of digital imaging in dentistry and the many uses of clinical photography. He then describes the principles of photography, as well as the camera equipment and supplementary equipment needed to obtain standard views in both dentistry and orthodontics.
