Face Proportion : Vertical Direction

The lower part is also known as anteroinferior facial height

The face proportion has 2 directions, the vertical dirction and the sagittal direction. In vertical direction, the face is divided into 3 parts:
1. upper
2. medium
3. lower

The upper third part is located between the trichion and the glabella points. The trichion and glabella points are sometimes difficult to locate. Trichion is where the upper partof forehead ends and the scalp starts. Glabella is marked between the eyebrows, few millimeteers above the nasion.

Exposure of Maxillary Incisors

Exposure of Upper Incisors

In facial esthetics, the upper incisors are directly associated to the upper lip in relation to important aspects, such as the length of the upper lip, teeth size, intrusion extrusion leve and vertical development of the maxilla.

In resting position and under normal conditions, depending on the size of teeth, the maxillary incisors must be exposed some 2 mm or 3 mm in relation to the upper lip stomion.

Diagnosis and treatment planning Simplified Straight-wire Technique

Simplified Straight-wire Technique was developed by Dr Messias Rodrigues from combining the light forces and freedom of Tip Edge Technique and stability from Straightwire. This union of concepts evolved into a simple, fast and effective orthodontic treatment technique.

Crossbite

Anterior crossbite is a common malocclusion encountered in children wherein the maxillary incisors are inclined lingually in relation to the mandibular incisors. It is an esthetic and functional concern of parents during the developmental stage of a child.

Delayed treatment can lead to serious complications such as loss of arch lenth, traumatic occlusion, stripping of gingival tissue and pocket formation.

An inclined bite plane can be fabricated to correct an anterior crossbite. It is advantageous to do early treatment during mixed dentition stage of tooth development. This simple appliance speedily corrects the abnormal locking of teeth with little or no discomfort and minimal patient compliance.

Orthodontics

Orthodontics is the branch of dentistry which is concerned with the growth of the face, developmentof the teeth, and prevention and correction of the improper bites.

When a person’s teeth are not aligned or are crooked and crowded, in placeor two teeth more than two or three teeth are present, or they protrude, affecting theappearance of theface and can also make the pronunciation of certain word different. It may lead to gum problems or cavities as those areas in the mouth cannot be maintained clean by oral hygiene measures.

A number of procedures are available for correcting the irregularities of teeth and its relation to the surrounding structures. One of these procedures used for this correction is orthodontics. Different appliances are used to put a constant but a gentle pressure on the teeth to move them into the correct position.

Orthodontic treatment helps in correcting the alignment of the teeth and its straightens the teeth, which eventually does the functionof chewing and it works better and difinitely looks better. It too helps in keeping the teeth cleaner than before.

Anterior Crossbite Correction

The management of anterior cross bites in the primary and early mixed dentition is highly recommended as this kind of malocclusion does not diminish with age. Moreover, if left untreated, anterior crossbites may lead to unsightly wear of the incisal and labial surfaces of the involved maxillary incisors, dental compensation of mandibular incisors resulting to thinning of labial alveolar plate and/or ginigival recession, loss of arch length, traumatic occlusion from cuspal interferences, and improper muscle balances leading to habitual posturing of the mandible. To prevent these complications, anterior cross bites should be treated early. There are recent designs of appliances and simplified techniques for anterior cross bite correction which can be easily and effectively rendered by the dentist. Useful guidelines as to which anterior cross bites are amenable to early intervention will be discussed as each case must be assessed on its merits and due consideration must be given to the presence or absence of a mandibular displacement on closing.

Quadrihelix Appliance

Transverse maxillary deficiency and constricted maxillary dental arch resulting to posterior crossbite can be genetic in origin or could be caused by environmental influences such as digit sucking and mouth breathing. In pre-adolescent patients, correction of the posterior crossbite, whether unilateral or bilateral, as soon as diagnosed is important to avoid further worsening of the transverse maxillary deficiency and maxillary arch constriction, prevent functional problem and mandibular shift on closure and at the same time provide more space for the eruption of the permanent teeth.

An appliance called quadrihelix, originally developed by Herbst can be used for expansion of a constricted maxillary arch to correct posterior crossbite in a pre-adolescent child. The combination of a posterior crossbite and a finger sucking habit is the best indication for this appliance.

Frankel Appliance

The goal of early treatment is to correct existing or developing skeletal, denti alveolar and muscular imbalances to improve the orofacial environment before the eruption of the permanent dentition is complete. By early treatment at a younger age, the overall need for complex orthodontic treatment is reduced. Frankel’s functional regulator is a myofunctional appliance developed by Professor Rolf Frankel of Germany. This appliance is also called as: Frankel appliance, vestibular appliance, oral gymnastic appliance and functional regulator.
