Not all dental implants are equal
The success of an implant will depend on the implant itself, the bone health of the patient and the professional course. Let's refer specifically to the differences in the quality of the materials used. Most dental implants currently used to replace missing teeth are made of titanium. Among the different shaped implants with osseointegrated (bone integrated) root, there are significant differences:
- The shape of the implant thread pattern;
- The presence or absence of a machined surface on the implant neck;
- The type and location of the abutment connection; and
- The presence of grooves on the implant body to promote greater bone anchor.
Surface chemistry can vary
This influences both the rate and the percentage of osseointegration. Also to be considered is the stability of the bone to implant connection and functional load anchorage.
Scientific documentation to support the company product warranty
It is important to consider all the scientific documentation to support the company product warranty, and not just the price.
Because there has been a rapid evolution in the development of implants by the major manufacturers (Zimmer, Straumann, Nobel, 3i etc.), both dentists and patients need to know what the current technology options are that are available and how to avoid choosing an outdated implant or even worse, an implant may have been manufactured by a company that is no longer in business.
New and improved implant designs
Improved implant surfaces and bone integration
The new implant designs improve the primary stability and bone implant contact (BIC) in all types of bone. The new implant surfaces that mimic the microscopic structure of bone increase osteointegration meaning that the implant embeds better into the patient's bone.
There have been significant Bioactive implant surface improvements such as adding titanium oxide enriched phosphate, fluoride ions, calcium phosphate, etc. manufactured in oxygen free environments to reduce oxidation contaminants, combined with storage in sterile saline.
Improved implant shapes
Changes in the shape of the implant and screw thread designs involve greater initial stability of the implant at the time of placement. Improved connections reorient support for biomechanical loads away from the bone crest, favoring aesthetics.
Tantalum implants and trabecular architecture
Recently, tantalum has been used to create a new kind of dental implant which includes a trabecular metal design that emulates the human cancellous bone. Tantalum is stronger and more flexible than titanium (as the modulus of elasticity is similar to that of cancellous bone), and the trabecular architecture has up to 80% porosity allowing approximately 2-3 times greater bone growth compared to conventional porous coatings and double shear. The pore size and high porosity supports vascularization and osseointegration. High technology trabecular metal implants have been used with excellent results for orthopedic implants and Zimmer Dental has had great success with its trabecular metal implants TM technology for use in implantology.
Patients can be reassured that IMTRA Incoma and Doctor Beatriz Galindo Martens are officially certified for Zimmer tantalum trabecular implants.
Although dental implants such as zirconia ceramics are not as well documented as titanium implants, they gain popularity among patients and physicians seeking "metal-free" alternative. When zirconium implants are perfectly placed, they can provide significant aesthetic advantages. Recently, Z-Systems of Switzerland updated its zirconium implant system resulting in a very interesting new option for dentists and patients.
Modern dental and implant technology considerations
To take advantage of new dental implant technology, the choice that professionals have to make with their patients should include consideration of the following factors:
- A "rough surface" to provide greater bone anchor;
- Site preparation and instrumentation required for implant placement;
- Shape and design of screw thread for optimum stability, depending on the type of bone;
- Stable connection of the internal pillar to better distribute the functional loads, thus preserving the crestal bone;
- Improvement of surface chemistry and surface of the implant to increase the amount of secondary stability (osteogenesis);
- Scientific documentation with prospective studies and clinical trials to verify the clinical efficacy;
- An implant manufacturer company chosen that is world renowned in biomedical manufacturing that complies with the following:
- Is currently still an active implant manufacturer;
- An officially approved implant manufacturer;
- Provides an adequate replacement warranty;
- Provides high quality professional technical support;
- Provides sterile packed implants with correct expiry dates for implants and prosthetic components.
- Provides continuing education courses for dental practioners.
