There are several reasons why the Ceramir Pediatric Crown is favourable to use compared to a Zirconia crowns.
THE MATERIAL USED IN CERAMIR PEDIATRIC CROWNS
The Ceramir Pediatric Crown material is not as hard as the Zirconia crowns that is extremely hard and can be damaging to the opposite tooth- the Ceramir Pediatric Crowns will have more natural feel for the patients.
TOOTH PREPARATION
By using the Ceramir Pediatric Crowns the preparation can be more conservative and minimized, less tooth structure needs to be removed compared to a Zirconia crown that needs more space to accommodate the crown's thickness.
AESTHETICS
The material consists of a natural glass phase, closely mimicking the natural appearance of teeth, providing a high level of aesthetics, whilst a Zirconia crown have a mor opaque appearance to natural teeth.
DURABILITY:
Ceramir Pediatric Crowns has strength more compatible to the natural tooth with its high bond strengths to tooth structure make these crowns durable, lasting the lifetime of the deciduous tooth.
Zirconia crowns are known for their very high strength and durability, making the resistant to fracture. However, when it comes to child patients, the primary concern is the long-term health and development of their natural teeth. Zirconia crowns may be considered too strong for child patients' teeth because they do not provide the same level of flexibility and adaptability as natural teeth. This lack of flexibility can potentially put excessive stress on the underlying tooth structure, leading to complications or damage over time. Therefore, dentists may prefer to use more conservative treatments options for children.
WEAR RESISTANCE
Ceramir Pediatric Crowns have a surface hardness between natural enamel and dentin (HV 100) making its wear pattern similar to that of the natural tooth.
The surface hardness of zirconia crowns is very high which may cause them to remain intact while the surrounding natural teeth wear down. This discrepancy in wear rates could potentially lead to an uneven bite or occlusion, affecting the child's natural bite alignment.
FIT AND RETENTION
Ceramir Pediatric Crowns, having a resin material giving it a modulus of elasticity of 20 GPa behaving similar to dentin. This allows for natural flexibility and excellent fit to the primary tooth. When bonded to tooth structure its acts as a monobloc with the primary tooth allowing for the natural micro-movements of the tooth.
Zirconia crowns require extensive tooth shaping and adjustments for an optimal fit. Its high strength does not allow for natural tooth movements.
REPAIRABILITY
In the event of chipping or fracture, Ceramir Pediatric Crowns can easily be repaired chairside with additional composite material.
Zirconia crowns may be more challenging to repair.
COST
Ceramir Pediatric Crowns are generally more cost-effective compared to zirconia crowns.
Zirconia crowns tend to be more expensive due to the higher cost of the material.
Zirconia crowns will also require more chairside preparation time compared to Ceramir Pediatric Crowns making Ceramir Pediatric Crown placement more comfortable to the child patient.
