logo 49 | The Camlog Partner Magazine 20 | Case study 7. Many of the more popular implant systems are integrated in the planning software. For immediate implantation, a PROGRESSIVE-LINE implant was selected, which is particularly suited for immediate restoration protocols due to its macro design. However, at the time of planning, the data were not yet stored in the software (exoplan). A SCREW-LINE implant (same diameter and length) was used for the correct virtual positioning of the implant. 8. The X-ray and surface scan data of teeth and jaw sections were superimposed in the software to establish the relationship of the virtually planned implant with regard to the tooth surface and mucosa. When placing the implant, attention was paid to place the screw access channel of the subsequent hybrid crown in the palatal surface. 9. The preparation of tooth 21 and the fabrication of an acrylic temporary with attachment were performed in the practice of the family dentist. For this purpose, dental technician (MDT Oliver Förster, Gauting, Germany) removed tooth crown 22 in the digital model and designed the base in the form of an ovate pontic to stabilize the peri-implant soft tissue during the healing phase and to maintain an anatomical emergence profile. 10. On the day of surgery, tooth 22 was extracted using microsurgical instruments in a tissue-sparing manner with the aim of preserving the buccal alveolar bone and without damaging the interdental papillae. Exposure of the alveolar bone was to be avoided because of esthetic limitations due to scarring. At the same time, the associated resorption of the bone lamella is minimized. 11. The bone compartment was cleaned and the apical lesion was completely curetted. The preparation was to be flap-less, according to the standard drilling protocol of the PROGRESSIVE-LINE implants with a pre-surgically prepared drilling template. The implant bed was prepared precisely with the completely guided drills of the guide system, whereby its sleeves prevent any deflection. 12. The virtual template design was converted into a delicately designed navigation template after approval. As the template was supported on the natural teeth, it was essential to keep the time span between impression taking and surgery as short as possible, as potential movement of the teeth could have a negative impact on the precise fit of the template and thus on the correct implant bed preparation and implant positioning.
