A night guard is meant to protect the teeth from clenching and grinding during sleep.
SPACE MAINTAINER is an appliance that is custom-made by a dentist or orthodontist in acrylic or metal material. It can be either removable or cemented in a child's mouth. Its purpose is to keep the space open to allow the permanent tooth to erupt and come into place.
1. Fixed space maintainer – the most common type of space maintainer. The term “fixed” means the device is “cemented” (glued) into place with dental cement and is not meant to be removable by the patient. This makes them more reliable at effectively achieving their goal. It also means they must be removed by the dentist at some point.
Four different kinds of fixed space maintainers:
v Transpalatal Arch Appliance - used in the upper jaw when primary molar teeth have been lost prematurely on both sides of the dental arch. TPA appliances are formed from two metal bands joined across the palate with a rigid wire, which is soldered to the bands. Making the device involves fitting the metal bands onto the child’s abutment teeth and making an impression (mold). The bands remain in the impression, which is then filled with dental plaster to produce a cast. The TPA device is made in a laboratory, on the casts of the child’s teeth.
v Unilateral, crown and loop – space maintainers are placed on one side of the mouth to hold space open for one tooth. The unilateral space maintainer wraps around the outside of the tooth and is connected to a metal loop that holds the space intact. The crown and loop is an actual crown that covers the tooth and is attached to the loop to ensure there is space for the erupting tooth.
v Distal shoe - is usually used for an unerupted first permanent molar tooth. It is a more complicated space maintainer because the end of the metal is usually inserted into the gum line to keep the open space from closing. A dentist will need to monitor the progress of the erupting permanent molar to make sure it can erupt properly with this space maintainer.
v Lingual - is usually bilateral in nature and may be cemented to molar teeth and connected by a wire on the inside of the lower front teeth. Usually this is used for more than one missing tooth.
2. Removable space maintainer - are similar to orthodontic appliances and are usually made of acrylic. In some cases, an artificial tooth may be used to fill a space that must remain open for the un-erupted tooth.
Some advantages and benefits of space maintainers include:
1. Space maintainers prevent undesirable movement of the permanent molar and bicuspid teeth.
2. Space maintainers preserve space in the dental arch for the bicuspid and permanent canine teeth to move into.
3. Space maintainers preserve the shape of the arc along which the teeth are positioned in the jaw (dental arch).
v Warranty regarding extension, retention, occlusion, contact etc. is only on the basis of the given model.
v All repetitions and correction should be informed within 7 days and will be accepted only with fresh models along with initially supplied model, work and warranty card.
v To claim warranty of Pine Dental prosthesis, the patient should consult the same doctor or clinic.
v Repetitions will be charged at 50% of the actual rate of the work and additional tax, if any.
v Patient cannot claim warranty in the pricelist will not have any warranty.
need 7 working days to complete a work except Friday and other
v Will be charge 10% extra. The fabrication time depends on prosthesis type and unit.
v The proximal margins of the abutments should be parallel or slightly tapering towards occlusal surface. Eliminate undercuts to the maximum. Round all corners.
v We always prefer perfect rubber base impression. Don’t pour die stone type IV immediately to the rubber base impression. Pour only after 1 hour.
v Don’t allow the alginate impression to get dried. Pour die stone type IV immediately. If the model thus prepared is found defective (air bubble, broken stump etc.) discard it and take a new impression rather than trying to produce a second model from the old alginate impression.
v We need upper and lower full Die Stone IV models to check the occlusion correctly.
v Provide the bite registration in Silicone putty (not in wax), if necessary.
v The shade will be perfect only if the labial and occlusal clearance is 2mm.
v VITA classical and VITA 3D Master 9of Ivoclar A-D shade number should be given for ceramic shade selection.
v Avoid grinding the metal prosthesis at the time of metal trial. This may lead to contamination of metal and ceramic chipped – off.
v In anterior case, if the patient is satisfied with the temporary crown / bridge, kindly provide a model of that which will help us in imitating the shape and arrangement. Pre – operative models will also be useful in some cases.
Is a type of all-ceramic crown which is preferred for its longer lasting, aesthetic qualities.
Lengthens the lower jaw by posturing it forward. It can also be used to cure an overbite, which can mean
