Pre-formed Zirconium Crowns
Zirconium crowns are increasingly being in paediatric dentistry across the globe.
Crowns are prefabricated with multiple sizes and shapes available for all teeth. They are an extremely durable restoration and as such are an invaluable material for paediatric dentists.
Indications for Zirconium crowns in deciduous (Baby Teeth):
- Teeth Fractured due to trauma
- Teeth with large carious lesions (holes)
- Teeth that have had pulp therapy
- Where the quality of the remaining tooth structure is poor (hypomineralized)
- Teeth with excessive wear (due to erosion or grinding habits)
- Children who require general anaesthesia for dental care
- Children with a high decay rate
Placement of Zirconia crowns
Zirconia crowns are cemented to the teeth using dental cements. This may be done using local anaesthetic or as a part of treatment under general anaesthesia.
Crowns go over the remaining tooth and restorative material inside the tooth.
Deciduous (baby) teeth with Zirconia crowns will normally exfoliate (Fall out) spontaneously.
Cleaning, care and maintenance of Zirconia crowns
- Zirconia crowns are cemented to the teeth but may become de-bonded
particularly with hard or sticky food (muesli bars, confectionary) - Teeth treated with a Zirconia crown still need thorough brushing and flossing to
maintain tooth and gum health - Teeth should have radiographs (x-rays) at least every two years to monitor the underlying tooth
