PROGRESSIVE-LINE Flyer

EXAMPLES OF CLINICAL APPLICATIONS Dr. Frederic Hermann, MSc. (from the Implantology Journal Special Edition 03 I 2019) The final drilling was carried out freehand. The distal positioning was due to the retention of the diastema. After the minimally invasive removal of the root, the pilot hole was drilled and the first form drilling carried out using a template created before the operation. Initial situation: a post crown broken in the root canal and a deep apical fracture in the root. Revision was contraindicated. The final treatment: a hybrid abutment made of zirconium dioxide created in a CAD/CAM process onto which a layered lithium disilicate crown was cemented. The anatomical shape of the hard and soft tissue was determined using replacement materials. The mould was made using the open tray technique. The PROGRESSIVE-LINE implant Ø 3.8 mm/L13 mm was positioned in a 0.4 mm supracrestal position in line with the protocol. The patient’s own tooth was used to stimulate the attached gingiva as a temporary measure. Two PROGRESSIVE-LINE implants were inserted. Primary stability of the implants was predominantly achieved by means of the crestal anchoring thread. Once the operation site had been augmented and the implants were covered, the soft tissue was able to be closed. After the incision and the preparation of a mucoperiosteal flap, the Schneiderian membrane was lifted by opening a lateral window. The cavity was first filled with a mixture of autologous and bovine bone substitute material. The occlusal view of the initial clinical situation shows a vertical and horizontal defect of the alveolar chamber in regions 15 and 16. In referral practice, final treatment is provided in the form of two monolithic zircon crowns being cemented onto modified titanium abutments. Image: Drs Fischer, Weilheim i. Obb. This occurred three months after the insertion. The prosthetic care started with the shaping of the soft tissue using gingival shapers. The control image shows the sinus floor elevation and the augmented area after the wound had been closed. The area was exposed after three months of covered healing. Dr. Jörg-Martin Ruppin
