16 CASE STUDY Fig. 6: Using a 4-mm punch, the mucosa in region 13 was precisely shaped around the implant base. Fig. 5: The iSy implant underwent transgingival healing. The basal parts of the attached gingiva of the vestibular and palatal aps were not detached. Fig. 4: The iSy implant was inserted according to the iSy drilling protocol using the pilot drill and single-patient form drill. palatal ap not detached. The drill se- quence in the iSy System is made up of a round burr, the Ø 2.8 mm pilot drill, and the single-patient form drill corresponding to the implant diameter, with the latter being supplied with the implant (Fig. 3 to 5) . In the area of the vestibular ap in re- gion 13, after insertion of the implant the mucosa was precisely shaped using a 4 mm punch. It is recommended to use the punch only after completing the implanta- tion because at this point only that area that is critical in this case for an harmo- nious gingival line is precisely and specif- ically reduced (Fig. 6 and 7) . At the time of the implantation, a wide gingiva former was not yet supplied with the iSy System which was why a punch was also used here that had a diameter slightly larger than that of the gingiva former. In this way, a naturally shaped emergence pro le is effectively obtained in order to optimally shape the soft tissue for a molar [5]. The suturing was done using Prolene 6/0 (Ethicon) and individual button sutures (Fig. 8 and 9) and radiographic ima- ging was carried out to check the situ- ation (Fig. 10) . When the sutures were removed seven days later, the tissue around the PEEK gingiva former was com- pletely free of irritation (Fig. 11 to 13) . Fig. 3: After the minimally invasive crestal incision, the implant bed was rst prepared using the round burr. Fig. 9: To achieve an esthetic emergence pro le, the soft tissue around the gingiva former in region 26 was removed using a slightly larger punch. Fig. 8: Individual button sutures were used to suture the mini- mally invasive incision around the gingiva former inserted into the implant base. Fig 7: Only that area critical for an harmonious gingival line was speci cally removed. Fig. 10: A radiographic image was taken at the end of the surgical procedure to check the situation. It shows an iSy implant with Ø 3.8 mm and a length of 13 mm in region 13 and in region 26 an implant of Ø 4.4 mm / L 11 mm with the pre- mounted implant bases that bear the PEEK gingiva formers.
