What is it?
In some cases, it is possible to insert the implants and load them with the prosthesis within 24 hours. The prosthesis is screwed onto the implants and, therefore, is immobile and allows the patient to avoid the inconvenience that a mobil prosthesis would entail.
When is immediate loading an option?
It should be noted that not all patients are ideal for immediate loading interventions.
To be carry out the procedure and to ensure long-term success of both the prosthesis and the implant, there are some necessary requirements:
- The absence of acute inflammation during surgery
- Adequate volume and density of the bone
- Minimum of four implants
- Proper occlusal loads: prosthesis in contact with the upper or lower dental arch or between the two prostheses if oral rehabilitation is complete, it must be balanced and evenly distributed across all teeth. Sometimes this involves an intervention to the ‘antagonistic’ arch (that opposite to the one operated) with prosthetic corrections before beginning the intervention. Furthermore, the patient must not have prior parafunctional activity, such as teeth grinding (bruxism), which would cause an overload of the implants during the osseointegration phase, and consequently a high risk of failure
- Good oral hygiene; heavy smokers (more than 15 cigarettes per day) are at risk
It is clear, therefore that the selection of patients who are candidates for immediate loading must be done prior to surgery to prevent the failure of the treatment plan.
