Tratamiento temprano en Ortodoncia “Retrospectiva Personal”

1.- CLASS ll TREATMENT- Utilizing the Herbst Appliance

almost two-thirds of his thirty years in practice, the question of treatment-timing is still a perplexing one. In any event, the speaker would like to present examples of his personal experience treating children in the mixed-dentition stages, and perhaps illuminate which situations are effectively handled at that time, and which could be delayed until later developmental stages.

One of the more challenging clinical problems in orthodontics involves correction of Class ll malocclusions. In many of these cases, the origin of the difficulty can be a skeletal retrusion of the mandible in addition to the dental malocclusion. In adults, mandibular retrognathia usually can only be treated effectively by surgical advancement . In growing children, it may be possible in some cases, to effect a substantial change in mandibular position without resorting to surgery later on.

2.- SELF-LIGATION- An Overview of the Speed System

Many “functional” appliances exist to “encourage mandibular growth”. The speaker has had some limited experience utilizing the Herbst appliance. Just what this encounter has produced in six consecutively treated cases will be presented. The intent of treatment was, of course, correction of the Class ll malocclusion., but also as importantly, to produce a positive improvement in facial profile. Was this accomplished in every case? What really did happen?

Lately, there has been considerable interest in the orthodontic community for development of appliance systems that will enhance efficiency in clinical practice. Although not at all new, self-ligation appliances have arrived and are produced by almost every orthodontic manufacturer today. Each version claims superiority over the others by virtue of “active or passive” interaction with the arch-wires. Speed System Orthodontics has produced a version of a self-ligation bracket that dates back to the 1980's. Coupled with these bracket systems are an assortment of specialty wires designed for the different stages of treatment.

By no means an authority on the subject, the speaker has had about five years experience using the Speed System. A brief description of the appliance, of the various arch-wires, and some examples of their use in various clinical situations will be demonstrated.

3.- EARLY TREATMENT- A Personal Retrospective

Over the last few years there has been considerable discussion in the orthodontic community about the wisdom of Early Orthodontic Treatment. Some advocate treatment as early as in the complete deciduous dentition, as a means of eliminating or at least minimizing future phases of treatment. Others claim that most ,if not all, problems can be adequately handled in the adult dentition. Many others take a more intermediate approach and have established their personal treatment timing preferences based on their own abilities, training and orthodontic philosophy. As evidence-based orthodontics evolves, more definite treatment-timing guidelines are sure to emerge to help the clinician with this difficult area.
