One of the more comforting aspects of practicing orthodontics is that we see few complications of treatment in comparison with, say, our colleagues in oral and maxillofacial surgery. Surgical complica...
Drs. Al-Awadhi and Finan list patient-related risk factors for root resorption and review evidence-based recommendations from the literature for avoiding orthodontically induced resorption. Appliance choices, types of tooth movement, force application, duration of treatment, and extractions are covered.
Lower incisor proclination due to loss of anchorage is almost unavoidable in conventional Herbst treatment. Drs. Manzo, Martina, Leone, and D’Antò demonstrate how to use miniplate anchorage to take advantage of the Herbst’s effectiveness in correcting mandibular retrusion while minimizing dental side effects.
This month’s Pearl shows how to modify bracket positioning on the upper lateral incisors during Phase I treatment to avoid premature distal root tip in the path of the erupting canines, thus preventing the development of an unsightly midline diastema.
This simple toothborne device, as described by Dr. Pithon and colleagues, can be installed as soon as the lower first permanent molars have erupted. Combined with rapid maxillary expansion, it eliminates the need for extraoral appliances or miniplate anchorage in a skeletal Class III case.

A hybrid tooth- and boneborne appliance is used with anchorage from an obliquely inserted miniscrew to treat a patient with the congenital absence of most permanent teeth. Prosthetic restoration is performed using a nylon-based denture material in both arches.

The authors describe how a biocompatible material called polyetheretherketone can be used to make an upper or lower lingual retainer by means of a completely digital workflow, with fabrication from either a milling machine or a three-dimensional printer.
This patient developed upper and lower buccal alveolar bone exostoses after premolar extractions and anterior retraction. The upper bony protuberance is removed with minor osseous surgery, and post-treatment follow-up shows normal healing and good orthodontic results.
