What is serial extraction in orthodontics?

Ortho Procedures - Serial Extraction. 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.

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 is serial extraction in dentistry?

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.

What is the order of extraction of tooth in serial extraction procedure?

However based on the usual eruption sequence of teeth, deciduous canines are extracted at the age of 8–9 years to create space for proper alignment of incisors, followed by extraction of deciduous first molars a year later so that the eruption of first premolars is accelerated and lastly extraction of the erupting ...

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.

Orthotrain - Lecture Session - Serial Extraction

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.

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.

What is Oligodontia?

Oligodontia is a rare genetic disorder which represents the congenital absence of more than six teeth in primary, permanent or both dentitions. It is usually a part of a syndrome and seldom occurs as an isolated entity.

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 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 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 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 flush terminal plane?

The distal surface of upper and lower primary second molar in centric occlusion is in a straight line is called as flush terminal plane. The distal surface of lower primary second molar is ahead or mesial to distal surface of upper primary second molar in centric occlusion is called as mesial step.

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.

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?

How do I remove orthodontic cement at home?

Brush your teeth like normal, taking care to get all the adhesive spots. Then, carefully use a dental pick to slowly scrub off the leftover glue. Rinse with warm water, then brush again. This time, the rest of the adhesive should come off.

Are braces cemented on?

Now that your teeth are prepped and ready for braces placement, the material is prepped. A bonding cement is placed onto the rear of each brace. This bonding cement will hold throughout the duration of the time you're wearing them, but can removed easily once the time comes.

How do you remove orthodontic cement?

Remove Band Cement

A sharp scaler is the most common hand instrument used to remove cement. Be sure to maintain a fulcrum and work away from the gingiva when possible. A band-removing or adhesive-removing pliers can be used to remove bulk adhesive, but be careful not to scratch the enamel.

What is Macrodontia in dentistry?

Total: Total macrodontia or macrodontism is an anomaly that occurs when all teeth are larger than usual. It is related to disorders such as gigantism and hemihypertrophy.

What is pseudo anodontia?

Pseudoanodontia is a descriptive term that indicates clinical but not radiographic absence of teeth that should normally be present in the oral cavity for the patient's dental and chronologic age.

What is hypodontia and anodontia?

Anodontia is a genetic disorder defined as the absence of all teeth. It usually occurs as part of a syndrome that includes other abnormalities. Also rare but more common than anodontia are hypodontia and oligodontia. Hypodontia is genetic in origin and usually involves the absence of from 1 to 5 teeth.

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 rubber band extraction?

As originally conceived, the atraumatic extraction technique entails placing an elastic band around the neck of a fully erupted permanent tooth. In time, the elastic band naturally and painlessly travels down the root toward its apex.
