34 I I case report _ immediate restoration In order to safely and exactly place the implants, theuseofasurgicaltemplatewasplanned.Themax- illary provisional denture was duplicated and the laboratory created a surgical template from it. The surgical template was used to determine the best prosthetic position for the implants (Fig. 3). After in- cisionandraisingaflap,theboneprovedtobeofgood quality and of sufficient volume to ensure a buccal bone wall of approximately 2 mm after implant placement. In all, six OsseoSpeed EV 3.6 S implants wereplacedinthemaxilla.Therecommendeddrilling protocol was followed, using the Twist Drill EV, Step Drill EV and Cortical Drill EV. The implants were in- serted with a torque of 25 Ncm, using a contra angle andtheImplantDriverEV(Fig.4).Thefinalinstallation was carried out manually. Subsequently, 2 mm Uni Abutments EV were manually connected to the im- plants using the Uni Driver EV (Fig. 5). Uni Abutment EVTemporaryCylinderswereplacedontheabutments toattachthetemporaryrestoration.Thesurgicalpro- cedure was completed by replacing the soft tissue flaps and suturing around the abutments (Fig. 6). The existing provisional denture was grinded generouslyatthelevelofthetemporarycylindersso thatitcouldbesafelyplacedontopofthecylinders. The maxilla was covered with a rubber dam to protect the newly sutured surgical wound (Fig. 7). The reduced temporary denture was secured to the cylinders with self-hardening plastic.
