Dental implants appear and function like natural teeth. As implants integrate into the bone structure, they have the advantage, when compared to bridges or total prosthesis (dentures), to prevent bone loss and thus improve and maintaine aesthetics over time.
Implants do not require the sacrifice of healthy dental structure as occurs in case of crowns and bridges, since the teeth adjacent to the implants are not involved in prosthetic rehabilitation. Dental implants improve the quality of life and make social relationships comfortable. Dental implants represents the “State of the Art” in the rehabilitation of edentulous ridges and their success is extremely high, predictable and long-lasting.
The aesthetics and perception of a dental implant is so natural that patients do not remember having lost a tooth in the area where the implant is inserted. Today it is not possible to know how long a dental implant can last, but it is likely that the implants inserted by the periodontist and under diligent maintenance can potentially last a lifetime.
If multiple implants are inserted, and if they have adequate primary stability after placement, they can be immediately loaded with a restoration. The choice between provisional or definitive is typically based on the patient’s esthetic needs, on the complexity of the clinical case and on the contours of the existing soft tissues or on the shape of the tissues to be obtained. In general, provisional restorations are used in aesthetically important areas whereby the further development of soft tissue contours (gingival) is essential to obtain biomimetics, while definitive restorations can be used in posterior areas of the mouth. An in-depth examination will determine if the patient is a candidate for complete reconstructions in a day or which is the most appropriate prosthetic rehabilitation.
COMPUTER GUIDED IMPLANTOLOGY – ALL ON FOUR
In selected cases it is also possible to perform the entire reconstruction in few hours. This technology employs a virtual surgery technique based on scanning data from a state-of-the-art CBCT. These data are used to create surgical guides with rapid 3D prototyping. These templates are then used to guide the implants during placement in a quick and precise way so that it is not necessary to raise a flap. Prefabricated dental elements can be inserted on the same implants immediately. The whole procedure usually lasts less than an hour: it is a minimally invasive surgical procedure and without sutures, patients show very little swelling and discomfort. Patient can experience function and aesthetics from the moment the implants are inserted .
The All-on-Four concept is based on the attempt to provide fully edentulous patients with a complete and fixed reconstruction at reasonable costs, without having to undergo additional grafting procedures. It is a method indicated for elderly patients or with severe atrophy. The introduction of 3-D surgical planning software makes this method even more valuable because it is possible to plan the best implant placement without additional grafting procedures and fabricate the prosthesis before implant placement. The day the implants are inserted, the prosthesis is positioned within a very short period of time, usually less than an hour. Thanks to minimally invasive surgery, recovery time and swelling is not significant.
