The fundamental aspect in the diagnosis of and treatment planning for an impacted maxillary permanent canine is the ability to recognize and predict its subsequent failure of eruption. Early diagnosis of canine displacement, in relation to the surrounding structures, is based primarily on a radio graphic examination. Nowadays CT scanning units are relatively few and imaging is expensive, their use is increasing. and they are now more freely available to the orthodontist in practice. It may still be difficult to justify using the method on a routine basis for the occasional and more...

The impact of acceleration techniques extends beyond their effect on the rate of tooth movement to many other applications due to their temporary effect on bone density. From a mechano-therapeutic standpoint, these localized effects may change the anchorage properties of individual teeth, and as a result, the application of these techniques around a targeted tooth and away from anchor teeth can help in reducing the movement of anchor teeth. Another area of interest is the anabolic effect of these techniques that when used wisely could tremendously change the boundaries of orthodontic tooth...

Orthodontics in its century of existence have had a lot of landmarks in its evolution, but very few can match the clinical impact made by micro-implants and the recently introduced infra-zygomatic crest (IZC) and buccal shelf (BS) orthodontic bone screws. Micro-implants and extra-radicular bone screws have brought about a renaissance to the field of orthodontics with its concept of absolute anchorage. It is an added armamentarium in the hands of an experienced clinician to overcome new clinical challenges and convert even borderline surgical cases to nonsurgical without compromising with the...
