ABSTRACT

The concept of Immediate Loading in Implantology was demonstrated during the 1980s. It was observed that dental implants exposed to an oral environment and subjected to operating loads reproduce a biological model similar to natural dentition.

A male patient, 65 years old, non-smoker and with no relevant medical history. The patient has chronic adult periodontal disease in an advanced state. The placement of six transmucosal implants in the upper maxilla was planned and we planned six for the mandible. All the implants placed were MG Osseous® from Mozo-Grau S.L., anatomical, self-tapping, with universal external hex and treated surface (RBM). First we performed surgery on the the upper jaw, placing the planned implants, and the following week we inserted the implants in the lower jaw. The provisional prostheses were made of resin and were placed in both cases 24 hours after each surgery. After the six weeks needed for the implant osseointegration passed, we began preparing the permanent prostheses.

Conclusions: 1. Today there is a high predictability in immediate implant-supported restorations. 2. The advantages of this type of prosthetic restorations to the patient are a high degree of comfort and immediate aesthetics and function. 3. It is sufficient to place 6 implants in both arches to perform immediate implantsupported restorations. 4. It is necessary to seek a symmetrical insertion of the fasteners, as well as an insertion torque of 35 to 45 Ncm. 5. In rare cases, if there is sufficient availability of bone volume in both height and width and appropriate professional experience, we can choose to perform noninvasive surgical techniques using transmucosal implant placement. 6. Provisional prostheses should be made of resin and all implants that have obtained primary stability during insertion must be splinted. 7. Six weeks of healing is enough to consider carrying out the patient’s final prostheses.
