Criteria for choosing a dental implant

Criteria for choosing a dental implant

Nowadays, dental implants are available in many shapes and a very wide range of prices. There are numerous criteria for choosing an implant and the patients request information that is structured in a simpler way and that provide answers to questions such as:

Is an implant better than a bridge on the adjacent teeth?

Yes, if the adjacent teeth are whole or if their estimated lifetime exceeds 5 years.

No, if the adjacent teeth have already undergone root canal treatments, metal reconstructions or crowns. Subsequent procedures or even the loss thereof would change the condition of the crown attached to the implant and would reduce its lifetime.

Does the implant type matter? What causes the price difference?

Yes! It matters a lot, because the implant does not have in-depth periodontal ligaments and receives all the masticatory forces, directly impacting the bone.

For the implants with lower prices (250-350 Euros), which look like a simple screw, the single bone area that opposes the vertical masticatory forces is the one formed between the implant spires. In the case of high masticatory forces, this area declines quickly over time, especially because it is not aided by a stump-implant connection or a long screw. These implants are recommended only in a large number, for that they may “mutually help” each other.

For the mid-range implants (500-700 Euros), the number of spires is higher, their angle is steeper and, often, the base of the implant is provided with an opening, through which the newly-formed bone holds the implant, ensuring greater resistance to the vertical and transversal masticatory forces. The connection with the prosthetic stump is stronger, higher in terms of surface and it greatly helps the implant, opposing the horizontal and transversal forces that may cause bone resorption over time.

Premium implants (1200-1500 Euros) have an additional tantalum sleeve that imitates the mid-section bone structure and allows for a perfect osteoincorporation; such implants have the longest lifetime.

Is the number of implants important?

Certainly. If a single implant is required, at least a mid-range one would be advisable, for a longer lifetime (a 98% success rate after 10 years). If several are required, for different directions, implants from the first category may also be used, because joining increases their lifetime.

In the past, it was thought that each missing tooth had to be replaced by an implant. Nowadays, at least 2-4 mandibular implants and 6-8 maxillary implants may be set in for supporting an entire arch.

It is absolutely contraindicated to insert a single implant in the molar area, “to set up a connection” with the remaining teeth by means of a bridge, because the implant does not have periodontal ligaments and it does not sink at all into the bone during mastication, while the teeth have varying mobility. This diverse mechanical behaviour leads to implant fracture or teeth loss.

At the Excedent practice we provide all the details that you require in order to make the best decision. We always provide the solution that best fits you functionally, aesthetically and financially. Our doctors have extensive expertise in working with different implanting techniques, in terms of both surgery and prosthetics, with works that showed very good predictive outcomes in the long run.
