From the very beginning, the time factor has been one of the biggest constraints when it comes to implantology. In 1965, Professor Brånemark established a bone healing time (period between the implant placement and the prosthesis insertion) of 3 to 6 months. This time frame has several disadvantages and can sometimes be a contraindication to an implant insertion, even though it often proves to be the best solution.
In some cases, an implant that sits very firmly in the bone can immediately be fitted with a prosthesis.
For a better understanding, it is interesting to take an example from a different medical discipline than ours. When you have a forearm fracture, the surgeon uses pins and casts your arm. From this point on, you are advised against carrying heavy loads or doing sports that could mobilise the bone fragments. However, if you are skilled, you can continue to write and use your arm to get dressed.... The stress on the healing bone is very low compared to the mechanical stability provided by the cast and pins.
Using this principle, it is possible to fit implants immediately. Provided that the mechanical stability of the implants is already very good when inserted, we can immediately fit them with crowns, as long as they do not come into contact with the other jaw's teeth.
Two main categories of indications need to be considered:
It is not possible to establish protocols for immediate insertion or usage for patients with:
