Ceramic dental implant
Dental implants have, in recent years, become an increasingly popular treatment option for replacing missing teeth, as they are a safe and aesthetic alternative to traditional crowns, bridges or dentures.
A study of 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 performed could increase by 5.7% by 2026 in the most conservative scenario and by 23% in the most optimistic scenario.

Ceramic dental implant vs titanium dental implant
Titanium dental implants have long been considered a standard in implant dentistry due to their very good mechanical properties and long-term clinical success. However, there has been an increasing incidence of patients who have developed titanium allergies, and the aesthetic results have not always been as desired due to discoloration of the gums in the implant area (dark gray).
In response to these disadvantages, all-ceramic (zirconia) implants have been gaining ground in recent years, with doctors and researchers looking for new opportunities to improve patient treatment.
Ceramic dental implants are made entirely of zirconia, which is, in fact, an extremely strong ceramic that is compatible with the bone structure of the oral cavity (high biocompatibility) and has a lower risk of bacterial infection.
A study conducted by the RWTH Aachen University Hospital Aachen, Germany, on the risk of mucophthalmitis (microflora) around zirconia implants compared to titanium implants found that after two weeks of exposure to plaque, the level of bacteria developed around ceramic implants was four times lower than around metal implants.
In addition, ceramic dental implants offer great aesthetics, thanks to their color which is similar to natural teeth. In the case of titanium implants, there may be situations after insertion that require additional interventions to mask a discoloration of the gum.
Advantages of all-ceramic dental implants
Here are the main advantages of choosing an all-ceramic dental implant treatment.
Biocompatibility and optimal osseointegration
One of the key criteria for a successful dental implant treatment is osseointegration, i.e. the ability of the implant to adhere to the bone.
The NobelPearl® dental implant, used in the DENT ESTET clinics, is a new and unique alternative to titanium implants. Consisting of two ceramic parts, the NobelPearl® implant with its special ZERAFIL™ surface, combined with a partially machined collar, provides superior osseointegration.
Dr. Alexandru Georgescu, Dental Implantologist / Periodontist DENT ESTET:
We choose the Nobel implant for its premium quality, but also for the benefits it offers in single-unit treatment solutions or the All-on-4 system. The Nobel Biocare dental implant offers more than just a smile, it's practically a chance at a new life for the patient. It's a choice that offers safety and international validation through scientific studies published in accredited journals.
Allergies and sensitivities
Lately there has been an increasing number of people who have allergies, skin sensitivities and compromised immune systems. Therefore, the implantation of metal devices should be seriously considered beforehand, especially as removing a titanium implant from the jawbone is not a simple procedure.
Ceramic implants are often used in patients with hypersensitivity. Thus, in cases where there are allergies and sensitivities, ceramic implants are a better choice.
Aesthetics
The main disadvantage of titanium implants is aesthetic. Patients with thin, translucent gums or those who are prone to receding gums may experience a discoloration of the implant area (dark-gray), which influences the aesthetic result.
NobelPearl® and Straumann Pure Ceramic® implants are designed to support a natural-looking soft tissue appearance, and the white-colored material is suitable for patients with a thin gingival biotype.
Corrosion resistant
Ceramic is a chemical corrosion-resistant material that does not conduct electricity or heat. Studies show that zirconia will not trigger chemical reactions, migrate to other places in the body or 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. In addition, corrosion occurs at a faster rate if other metal products (such as metal crowns, bridges or metal inlays) are in the vicinity.
In conclusion, all-ceramic dental implants have demonstrated their benefits compared to titanium implants, confirming their long-term sustainability.
In the DENT ESTET clinics, implants and related prosthetic works are customized according to the color, shape and size of the natural teeth to meet the aesthetic and functional needs of the patient.
