When do we do serial extraction?

Based on the typical eruption pattern of the teeth, the treatment plan should involve extracting the deciduous canines around 8 to 9 years-old in order to create space for the proper alignment of incisors. This should be followed by the extraction of deciduous first molars a year later.

What is the purpose of serial extraction?

The purpose of serial extraction is to encourage the early eruption of the first premolars ahead of the permanent canines and should only be considered where there is an arch discrepancy of >4 mm.

What are the indications of serial extraction?

Absence of physiologic spacing. Unilateral or bilateral premature loss of deciduous canines with midline shift. Malpositioned or impacted lateral incisors that erupt palatally out of the arch. Markedly irregular or crowded maxillary and mandibular anteriors.

What is the order of serial extraction?

Serial extraction is a sequential plan of premature removal of one or more deciduous teeth in order to improve the alignment of permanent teeth and then removal of permanent teeth to maintain the proper ratio between tooth size and arch size.

When do you extract primary canines?

One suggested intervention to prevent ectopic eruption of the permanent canine is to extract the primary canine in individuals aged 10 to 13 years, provided that normal space conditions are present.

Orthodontics - Serial Extraction

Should baby teeth be pulled to make room?

Extraction Considerations

If a baby tooth is damaged or begins to decay, it may be necessary to extract the tooth in order to save gum health and eliminate pain. However, extracting a baby tooth before it is time for the permanent tooth to erupt can allow surrounding teeth to shift to fill the gap.

What is ectopic eruption of teeth?

Ectopic eruption is a disturbance in which the tooth does not follow its usual course. The purpose of this manuscript is to provide a brief review regarding the incidence, etiology, classification and different management techniques used for correcting ectopically erupting permanent first molar.

Why posterior teeth are extracted first?

Why are Maxillary Teeth Extracted before Mandibular teeth? It prevents any fall of enamel or restorative debris from falling into the extraction sockets of the lower arch.

Who introduced serial extraction?

Robert Bunon (1743) was the one to primarily explain serial extraction. Kjellgren (1929) coined the term “serial extraction”. Nance (1940) is known as the “Father of serial extraction”. The other pioneers who advocated this procedure were Hotz, Tweed, Dewel and Jack Dale.

When do you use the lingual arch space maintainer?

The conventional lingual arch is a nonfunctional fixed space maintainer used in the mandibular arch to maintain arch length by the prevention of mesial movement of the permanent first molars.

Which parameter is a contraindication for serial extraction?

Contraindications. Serial extraction should not be performed in the following circumstances: Class I malocclusions where the lack of space is slight and the teeth show only mild crowding. Where there is a skeletal discrepancy in the dental arches.

What causes midline diastema?

The most common etiology for midline diastema was supernumerary teeth followed by morphology labial frenum and nasal airflow condensation. The quality analysis of these studies based on NOS showed one study with unsatisfactory, four studies with satisfactory, and three with good quality.

What is ditching in orthodontics?

A defect at the junction between a restoration and the tooth.

What is Multiple Extraction?

In a multiple extraction procedure, a quantity of solvent is used to extract one layer (often the aqueous layer) multiple times in succession. The extraction is repeated two to three times, or perhaps more times if the compound has a low partition coefficient in the organic solvent.

How do you get more space in orthodontics?

Methods of Space Gaining

1. Proximal stripping. ...
2. Arch expansion. ...
3. Distalizationof molars.
4. Molar distalization is a process in the field of Orthodontics which is used to move molar teeth, especially permanent first molars, distally (backwards) in an arch. ...
5. Uperightning of posterior teeth. ...
6. Derotation of posterior teeth.

What cement is used for orthodontic bands?

Zinc phosphate cements are widely used for cementation of orthodontic bands. These cements are generally available as hand-mixed powder-liquid systems, although some encapsulated products are marketed.

What is Crossbite in dentistry?

What Is a Crossbite? A crossbite happens if your teeth don't line up properly when your mouth is closed. It can affect a single tooth or groups of teeth, like your front or back teeth. Normally, your upper teeth are wider and sit on the outside of your bottom teeth.

What is space maintainer?

What is a Space Maintainer in Dentistry? Dental space maintainers are devices used to leave enough space open for permanent teeth to grow in after baby teeth are lost prematurely. While it might not seem like a big problem at first, not taking care of a gap can lead to expensive problems down the road.

What is a temporary teeth?

Baby teeth are also called primary, or deciduous teeth, because they're temporary and they fall out. A full set of baby teeth is 20 teeth: 10 on top and 10 on bottom. We get baby teeth because as a child, our mouths aren't big enough for a full set of adult teeth, but kids still need teeth to chew.

What is the most common tooth to be extracted?

The most commonly extracted tooth type in all age groups was the molars (60%), followed by premolars (30.8%) and anterior teeth (9.2%, Table 3).

What is Transalveolar extraction?

Removal of an erupted tooth involves the use of controlled force in a manner such that the tooth is not pulled from bone, but instead, it is gently removed from its socket. During pre-extraction planning, the degree of difficulty anticipated for removing a particular tooth is assessed.

Why is curve of Spee important?

This normal occlusal curvature is required for an efficient masticatory system. Exaggerated curve of Spee is frequently observed in dental malocclusions with deep overbites. [1] Such excessive curve of Spee alters the muscle imbalance, ultimately leading to improper functional occlusion.

What causes ectopic eruption?

An ectopic eruption can occur when the permanent molar has an altered path of eruption in a mesial angular direction. The permanent molar can erupt in a detrimental position, under the distal of the second primary molar, or impacted against the first permanent molar.

How is ectopic eruption treated?

The purposes of treatment of ectopic first molar are movement of the tooth distally to its normal position in occlusion and correction of the mesial angulation to regain space for normal eruption of the second premolar. Majority of cases with spontaneous self-correction occurs before the age of seven.
