Orthodontics and occlusion

The discipline of orthodontics is directed towards alteration of the occlusion of the teeth and the relationships of the jaws. It is therefore somewhat surprising to find that there is little scientific evidence to support any of the concepts that suggest occlusal goals for orthodontic treatment. Most of the current concepts of orthodontic treatment are based upon personal opinion and retrospective studies. Nevertheless, an attempt is made here to provide a guide to the relationship of orthodontics and the occlusion that is evidence based. Where the evidence is weak, these areas have been highlighted.

Early Class II treatment

The treatment of children presenting with a Class II division I malocclusion involves one of two approaches. The first provides treatment in two phases; one of intervention during the mixed dentition (phase I) followed by a second definitive course of appliance treatment in early adolescence (phase II). The second approach involves providing a single course of comprehensive therapy during adolescence. The debate for and against early treatment is discussed alongside key, clinically relevant evidence related to Class II division I malocclusions.

Gelb 4/7

The airway governs our ability to breathe and to achieve a restful, oxygenated, restorative night’s sleep, as well as to perform optimally during the day. Any temporomandibular joint or occlusal philosophy must address airway patency while managing pain and dysfunction, identifying contributing factors and alleviating perpetuating factors. The teeth are the last piece of the Airway Centric paradigm. The airway is the first, then the joint and muscle and, lastly, the occlusion

Maxillary Expansion

Maxillary transverse discrepancy usually requires expansion of the palate by a combination of orthopedic and orthodontic tooth movements. Three expansion treatment modalities are used today: rapid maxillary expansion, slow maxillary expansion and surgically assisted maxillary expansion.This article aims to review the maxillary expansion by all the three modalities and a brief on commonly used appliances.

Speech And Malocclusion-A Review

Speech is the process to address and interact with one another to deliver ones point of view.It
is an important part of human development anda effective way to let people know what we
think. As orthodontist our role is not only to bring about esthetic corrections in patients but
also to bring form and function to the stomatognathic system.Lack of proper alignment, is a
possible cause for speech disorders. However, there are various known causesofspeech
impediments, such as " hearing loss, neurological disorders, brain injury, intellectual
disability, drug abuse, physical impairments such as cleft lip and palate, and drug abuse or
misuse.This article throws light upon speech distortion related to malocclusion.

Malocclusion and Hair Loss: An Intimate Relationship

A malocclusion is an incorrect relation between the teeth of the two dental arches when they approach each other as the jaws close. There are different categories of malocclusion:
Class 1 malocclusion is the most common. The bite is normal, but the upper teeth slightly overlap the lower teeth. Class 2 malocclusion, called retrognathism or overbite, occurs when the upper jaw and teeth severely overlap the bottom jaw and teeth. Class 3 malocclusion, called prognathism or underbite, occurs when the lower jaw protrudes or juts forward, causing the lower jaw and teeth to overlap the upper jaw and teeth. Hair loss (alopecia) can affect just your scalp or your entire body, and it can be temporary or permanent. It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging. Anyone can lose hair on their head, but it's more common in men. Baldness typically refers to excessive hair loss from your scalp. Hereditary hair loss with age is the most common cause of baldness. Some people prefer to let their hair loss run its course untreated and unhidden. Others may cover it up with
hairstyles, makeup, hats or scarves. And still others choose one of the treatments available to prevent further hair loss or restore growth.

Obstructive Sleep Apnea and the Orthodontist

Think back to your most stressful and exhausting finals week (for me it was my second year
in dental school—14 finals in five days). Recall how you felt after surviving on caffeine and adrenaline and no sleep: irritable, physically tired, mentally fuzzy, short-tempered, and unfocused. When it was over, it took a few days or even weeks to catch up on sleep and rejuvenate.
