Ceramic dental implant

In recent years, dental implants have become an increasingly popular treatment option for replacing missing teeth, as they offer a safe and aesthetically pleasing alternative to traditional crowns, bridges or dentures.

A study on the prevalence of dental implants in the United States showed a significant increase in demand for this type of treatment between 1999 and 2016, with researchers estimating that the number of dental implants placed could rise by 5.7% by 2026 in the most conservative scenario, and by 23% in the most optimistic scenario.

Titanium dental implants have long been regarded as the gold standard in implantology, thanks to their excellent mechanical properties and long-term clinical success. However, there has been a growing number of patients developing allergies to titanium, and the aesthetic results have not always been as desired due to gum discolouration around the implant site (dark grey).

To address these drawbacks, implants made entirely of ceramic (zirconia) have gained increasing ground in recent years, with doctors and researchers seeking new opportunities to improve the treatments offered to patients.

The ceramic dental implant is made entirely of zirconia, which is, in fact, an extremely durable ceramic, compatible with the bone structure of the oral cavity (high biocompatibility) and associated with a lower risk of bacterial infections.

A study conducted by the University Hospital of RWTH Aachen, Germany, on the risk of mucositis (microflora) developing around zirconium implants compared to titanium implants revealed that, after two weeks of exposure to bacterial plaque, the level of bacteria developed around the ceramic implants was four times lower than around the metal ones.

Furthermore, ceramic dental implants offer excellent aesthetics, thanks to their colour being similar to that of natural teeth. With titanium implants, after insertion there may be situations requiring additional procedures to mask discolouration of the gums.

Here are the main advantages of choosing a dental implant treatment made entirely of ceramic.

Biocompatibility and optimal osseointegration

One of the key factors in the success of dental implant treatment is osseointegration, i.e. the implant’s ability to bond with the bone.

The NobelPearl® dental implant, used in DENT ESTET clinics, represents a new and unique alternative to titanium implants. Consisting of two ceramic components, the NobelPearl® implant, with its special ZERAFIL™ surface combined with a partially machined collar, offers superior osseointegration.

Dr Alexandru Georgescu, dental implantologist / periodontist at DENT ESTET:

We choose the Nobel implant for its premium quality, but also for the benefits it offers in single-tooth treatment solutions or in the All-on-4 system. The Nobel Biocare dental implant offers more than just a smile; it is, in effect, a chance at a new life for the patient. It is a choice that offers safety and international validation through scientific studies published in accredited journals.

Allergies and sensitivities

Currently, there is an increasing number of people with allergies, skin sensitivities and compromised immune systems. Therefore, the implantation of metal devices must be carefully considered beforehand, especially as the removal of a titanium implant from the jawbone is not a simple procedure.

Ceramic implants are often used in patients with hypersensitivity. Thus, in cases where allergies and sensitivities are present, ceramic implants are a better choice.

Aesthetics

The main disadvantage of titanium implants is aesthetic in nature. Patients with thin, translucent gums or those prone to gum recession may experience discolouration of the implant area (dark grey), which affects the aesthetic result.

NobelPearl® and Straumann Pure Ceramic® ceramic implants are designed to support a natural appearance of the soft tissues, with the white material being suitable for patients with a thin gingival biotype.

Corrosion-resistant

Ceramic is a material resistant to chemical corrosion that does not conduct electricity or heat. Studies show that zirconia will not trigger chemical reactions, will not migrate to other parts of the body, and will not interfere with maintaining good oral health.

In contrast, titanium metal implants corrode slowly in the mouth due to moisture, in a process similar to rusting. Furthermore, corrosion occurs at a faster rate if other metal products are present nearby (such as metal crowns, bridges or metal inlays).

In conclusion, all-ceramic dental implants have demonstrated their benefits compared to titanium implants, confirming their long-term durability.

At DENT ESTET clinics, implants and associated prosthetic work are customised according to the colour, shape and size of the natural teeth, to meet the patient’s aesthetic and functional needs.
