Metal free dental implants

A missing tooth or teeth can be a major dental issue for most people with aesthetic and functional problems. This is not a good look at the front of the mouth but even from the side, a large gap can ruin a smile. Teeth are designed for a certain reason , whether that be for biting and tearing food ( front teeth) or chewing ( molars). The loss of even one tooth can impact on everyday eating habits and long term issues with the bite. For example, teeth will slowly move into the space left by an extracted tooth by either drifting in sideways or the opposing tooth moving up or downwards ( over eruption). This can dramatically impact on how one eats and damage the other teeth in the long term. The answer is to the replace the tooth in good time!

Most dental implants are made from titanium which is classified as a biocompatible material. However, reports have suggested that 0.6% of the population may have a hypersensitivity or allergic reaction to titanium and this would not be a suitable material. Increasing, we are hearing that patients would like to avoid any form of metal within the mouth as a personal choice akin to not having amalgam fillings. This is perfectly acceptable and there is an alternative option with zirconia ( zirconium dioxide) implants. These are metal free dental implants that are white in colour and hence are aesthetically pleasing. We use zirconia a lot in dentistry and the material is routinely used for crowns on back teeth and crowns for implants. We have never come across an allergic reaction to zirconia nor seen any form of hypersensitivity. Zirconia is bioinert meaning it does not release any ions like some metals can which reduces the risk of an immune response.

Our case of the month demonstrates a metal free dental implant to replace a missing upper premolar tooth. Our patient had specific requirements in terms of medical health and did not want any metal inserted within her mouth. Therefore our plan was a zirconia Nobel Pearl dental implant.

Dental implants are still the best way to replace missing teeth but we do appreciate that not everyone will want titanium implants. Ceramic zirconia implants are becoming more popular and we are pleased to offer this solution for those that want a metal free option.
