After 6 months of occlusal function of the provisional prosthesis, a gingival flap was made to discover the 4 submerged implants to be connected to the final prosthesis by abutments for overdentures.
However, these authors used a protocol of immediate loading in six implants that had a provisional restoration retained in standard pillars, and our study used only two small-diameter implants for a muco-implant-supported retention of the provisional prosthesis until the sixth month.

The maintenance of the ridges bones during the extraction, the primary stability of the implant, a careful control of the soft tissues, and proper manufacturing of the provisional prosthesis
are important factors for long-term clinical success [7-9].
In selected healthy patients, significant time and clinic visits may be saved by simultaneous extraction, implant placement, and restoration with a simple acrylic resin provisional prosthesis
. The reduction in postoperative visits, an absence of postoperative complications and the enthusiasm of patients who receive this treatment suggest that approaches to simplifying implant rehabilitation may increase patient acceptance.
In the meantime, to provide an immediate temporary solution and to enable the patient to recover socially, the maxillofacial prosthodontist constructed an eyeglasses-supported provisional prosthesis.
Finally, we reconnected the provisional prosthesis to the eyeglasses with a bolt (Figure 7(b)) and delivered the prosthesis to the patient (Figure 8).
Thus, the patient was informed about the possibility of applying immediate fixed provisional prosthesis if at the time of implant insertions; most of the implants had showed an insertion torque higher than 45N-cm, as reported by Cannizzaro et al.
All the implants showed an insertion torque higher than 45N-cm, so the remaining teeth could be removed (Figure 6), postextractive alveoli were filled with collagen sponges, and screwed provisional prosthesis was delivered.
During the healing phase, natural teeth were prepared and abutments were then covered with a provisional prosthesis
to condition soft tissues, whereas 2.7 and 3.7 were extracted, regarded as hopeless.
Following the inclinations outlined by the provisional prosthesis, the bone site for implant placement has been prepared (Figure 6).
To schedule the permanent prosthesis model, using the indications the provisional prosthesis gives us, it is an optimal surgical guide for implant placement.
