When do you 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.

Why is serial extraction done?

Serial extraction will help both in closing an open bite and relieving crowded position of the incisors which may be existing in an open bite case. Premature loss of deciduous teeth, especially of the deciduous canine, is sometimes reported in literature as the cause of retention of the corresponding permanent tooth.

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.

For which of the following malocclusion is serial extraction most appropriate?

The most favorable morphologic factors for serial extraction include class 1 malocclusion, a favorable morphogenetic pattern – one that does not change, a flush terminal plane or a mesial step relationship of the primary second molars, minimum overjet and minimum overbite.

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.

Orthodontics - Serial Extraction

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).

Which teeth are the easiest to extract?

Most upper teeth are easy to get numb for an extraction. Most lower teeth are also easy except the back molars. The lower back molars are much more difficult to get numb because the bone is so thick around them that anesthetic has trouble soaking through and there are several different nerves that go to them.

What is serial extraction in orthodontics?

A serial extraction is the planned extraction of teeth in a strategic sequence in order to guide the erupting permanent teeth into a more ideal position.

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.

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.

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.

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.

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.

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.

How do you get more space in orthodontics?

What is a distal shoe space maintainer?

This appliance is called a distal shoe space maintainer or a distal extension space maintainer. It is used to prevent first permanent molars from moving mesially with the premature loss of second primary molars. The example shown is a crown with a distal extension segment soldered to the crown.

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.

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 leeway space dental?

Leeway space, the most crucial space for the alignment of permanent teeth, is the difference between the sum of the mesiodistal crown widths of the primary canines and molars and that of their successors, the permanent canines and premolars [1].

What is partial Anodontia?

Anodontia is the congenital absence of teeth and can occur in some or all teeth; whereas partial anodontia (or hypodontia), involves two dentitions or only teeth of the permanent dentition (Dorland's 1998).

What is the most difficult tooth to extract?

What is the most difficult tooth to extract? Impacted wisdom teeth are wisdom teeth that have failed to erupt properly. They are generally considered to be the most difficult teeth to extract.

What is the most difficult dental procedure?

Implants are one of the most complex dental procedures, but this doesn't mean bad news. The dentist will numb the nerves of the area with local anesthesia during the process. You may feel pressure at times, but it won't cause pain.

How many teeth can be pulled at once?

There is no limit to the number of teeth you can have extracted at once. While having multiple teeth extracted during the same procedure is rare, it is sometimes the only option for patients with severe tooth decay.

What are the three main types of extraction methods?

The three most common types of extractions are: liquid/liquid, liquid/solid, and acid/base (also known as a chemically active extraction). The coffee and tea examples are both of the liquid/solid type in which a compound (caffeine) is isolated from a solid mixture by using a liquid extraction solvent (water).

When do you extract over retained primary teeth?

However, in cases where the primary tooth is fused to the bone, decayed, causing overcrowding, or structurally weak, your child's dentist may recommend extraction.
