Why is the selection of Dental Implant Material so important for biocompatibility?

Teeth, restorations, or any dental prosthesis including dental implants in the oral cavity have to function in one of the most inhospitable environments in the human body. They are subject to larger temperature and pH variations than most other parts of the body. Corrosion, the graded degradation of materials by electrochemical attack, is of concern particularly when dental implants are placed in the hostile electrolytic environment provided by the human mouth. Allergic reactions may occur from the presence of ions produced from the corrosion of implants. The present article describes various manifestations of allergic reactions due to implant material in the oral cavity.50 Well-educated patients understand the critical importance of appropriate, biocompatible and dental material selection . Before selecting a material for dental applications, it is necessary to remember that the choice of the material depends on a number of factors such as

  1. Corrosion Behavior

  2. Mechanical Properties

  3. Cost

  4. Availability

  5. Biocompatibility

  6. Aesthetic Appearance

Thus, for the application of existing and new dental materials, it is essential for the patient and especially the dentist to have a comprehensive knowledge of these attributes.

Zirconia Implants Better than Titanium Implants?

In the dental implant market, the ceramic dental implant is considered the Rolls Royce of dental implants compared to titanium implants which can be compared to your everyday budget car. The question every patient must ask themselves, “do I want to risk putting ‘budget’ materials into my body, blood supply, tissues and cranial structures or is my health worth the premium metal-free clinical solution on the dental implant market?” Perio-implantitis is the number one cause of titanium implant failure – unlike zirconia dental implants which have a less than 2% instance of perio-implantitis long term.

History of Zirconia & Metal-Free Dental Implants

Historically, Titanium and titanium alloys are widely used for fabrication of dental implants. Because of potential immunologic and possible esthetic compromises with titanium implants, novel implant technologies have been developed over the course of the last 30 years and the mobilization to superior implant materials has started to take hold. Not only do these novel technologies maintain the characteristics that provide titanium implants with their high success rates but they also achieve benefits beyond the attributes of the go-to titanium implant. Zirconia implants were introduced into dental implantology as an alternative to titanium implants. Zirconia is far more suitable as a dental implant material because of zirconia’s near perfect characteristics such as its tooth-like color, mechanical properties, biocompatibility, and low plaque affinity. The aim of this educational clinical review is to disclose the research conducted along with benefits of zirconia dental implants, compare them with titanium dental implants, and provide information on zirconia dental implant osseointegration and mechanical strength. Zirconia dental implants have the potential to become the “GOLD STANDARD” alternative dental implants to titanium dental implants, even while they remain underused by the dental community.
