Soace Maintainer 1 Flashcards
What is the importance of primary teeth in pediatric dentistry?
Act as a guide for the permanent tooth that replaces it.
What percentage of children have spacing in their primary dentition?
40%.
What is the purpose of generalized spacing in primary dentition?
Allows for adequate space for the permanent dentition.
What are Primate Spaces?
Spaces seen in primary dentition, with an incidence of 70% in maxillary and 63% in mandibular.
What is the Early Mesial Shift?
Mesial migration of the erupting mandibular permanent molar using the mandibular primate space.
At what age does the Early Mesial Shift typically occur?
Around 6 years of age.
What is the Late Mesial Shift?
Mesial migration of erupted mandibular permanent molar after the loss of the primary second molar.
What is the Leeway Space?
Extra space created because premolars are smaller than the primary teeth they replace.
What are the three types of occlusal relationships of primary teeth?
- Straight terminal plane * Mesial Step * Distal Step
What can cause premature loss of primary teeth?
- Extraction due to caries or injury * Premature exfoliation due to abnormal root resorption * Congenital absence
What is a space maintainer?
An appliance that keeps the space open until the permanent tooth comes in.
What is the definition of arch length?
The distance from the distal surface of the second primary molar to the same surface on the opposite side.
What are the methods for determining arch length adequacy?
- Nance analysis * Moyer analysis * Tanaka and Johnston analysis * Hixon and Oldfather * Kaplan, Smith and Kenarkf * Bishara and Staley
What is the sequence of serial extraction?
- Extract deciduous canines * Extract first deciduous molars * Extract first premolars * Extract second deciduous molars
What are the functions of a space maintainer?
- Maintain space * Prevent movement of adjacent teeth * Prevent overeruption of opposing teeth * Improve esthetics * Assist in speech
What are the ideal prerequisites of a space maintainer?
- Simple to construct * Durable and strong * Passive * Easily cleanable * Readily adjustable
When is a space maintainer indicated?
- Premature loss of primary molars * Loss of primary canine
What are the classifications of space maintainers?
- Removable * Fixed * Semi-fixed
What are the types of fixed space maintainers?
- Band and loop * Crown and loop * Lingual arch * Nance appliance
What factors should be considered when planning a space maintainer?
- Time elapsed since loss of primary tooth * Dental and periodontal condition * Arch length * Age * Presence/absence of permanent successor
What are the indications for a Band and Loop space maintainer?
- Loss of primary molar during eruption of first permanent molar * Loss of two posterior teeth
What are the advantages of the Band and Loop space maintainer?
- Easy to construct * Inexpensive * Non-invasive * Allows eruption of permanent tooth
What are the disadvantages of the Band and Loop space maintainer?
- Does not restore masticatory function * Does not prevent extrusion of opposing dentition
What are the indications for a Lingual Arch space maintainer?
- Premature loss of primary posterior teeth * Base for aesthetic restoration in loss of anterior teeth
What are the advantages of the Lingual Arch space maintainer?
- Maintains esthetic arch form * Not easily displaced * Easily cleaned
What are the indications for a Nance appliance?
Used for multiple tooth loss in the maxillary arch.
What are the adverse effects of space maintainers?
- Dislodged appliances * Plaque accumulation * Interference with successor eruption
What should parents be informed about regarding space maintainers?
- Requires monitoring * Must maintain adequate oral hygiene * Appliance may break
True or False: The premature loss of primary incisors usually requires the maintenance of space.
False.
What is the purpose of a space regainer?
To prevent future space loss and dental problems
Space regainers are used in orthodontics to maintain or create space for teeth that are in the process of erupting or have been lost.
True or False: Extensive orthodontic treatment may be required if teeth are not properly aligned.
True
Misalignment of teeth can lead to various dental issues that may necessitate comprehensive orthodontic care.
Fill in the blank: A space regainer is used to _______.
[prevent future space loss]
This device helps maintain the dental arch’s integrity during orthodontic treatment.
What can be a consequence of not using a space regainer?
Future space loss and dental problems
Failure to maintain space can lead to complications in tooth alignment and positioning.
What type of treatment can move teeth back in place?
Orthodontic treatment
Orthodontics involves various methods, including braces and aligners, to correct tooth positioning.
