Described below is one case selected among those who have so far been treated with this suggested protocol. This study was conducted in accordance with the Decla- ration of Helsinki of 1975 and revised in 2000. In- formed consent was obtained from the subjects for participation in this study. Clinical case A 52-year-old male patient presented with sore- ness in position 1.4. Clinical evaluation accompanied by intraoral X-ray revealed a complete vertical frac- ture (Figs. 1 & 2). An atraumatic avulsion was per- formed with piezoelectric instruments (Piezosur- gery®, Mectron; Fig. 3). The implant site was prepared with ultrasonic inserts (Piezosurgery®, Mectron) at the palatal root. Site preparation was then completed with implant drills, as always performed and sug- gested by the authors.35 Before insertion of the im- plant, the post-extraction socket (in both the vestib- ular and palatal space) is filled with biomaterial (used in this case was calcium triphosphate, R.T.R.®, Septodont; Fig. 4). The fixture was then inserted ( AnyRidge®, 4 x 13 mm, Megagen Implants; Fig. 5) and the primary stability achieved and verified with Osstell® (65 ISQ; Figs. 6–8). The coronal gap, as usual, was then filled with additional biomaterial (Figs. 9–11). The postoperative intraoral X-ray shows the correct position of the implant (Fig. 12). Finally, the patient was instructed in home hygiene and care with chlor- hexidine rinses (0.2 %, every 12 hours for 10 days) and antibiotic therapy (amoxicillin and clavulanic acid, 1 g, every 8 hours for 6 days). 18 implants 1 2017
