CLINICAL CASE
All-on-4® treatment concept
Prof. Enrico Agliardi
Thanks to the new Xeal surface, I can get early soft tissue healing and sealing around the abutment. Xeal abutments are a must-have product for all clinicians performing immediate loading procedures.
Initial clinical situation
Front, side and profile images of the fully edentulous patient. Note the lack of lip support because of the bone resorption.
Intraoral view with removable dentures in both maxilla and mandible (left).
Moderate ridge resorption with estimated bone quality of D3 to D4 in the maxilla and D2 to D3 in the mandible (right).
Occlusal view of the maxilla (left).
Mandible showing unfavorable ridge form (right).
Surgical procedure - Maxilla
Making a palatal incision for flap elevation (left).
Full-thickness flap elevation in the maxilla (right).
Preparing the osteotomy in the midline using a Ø 2 mm Twist Drill for insertion of the All-on-4® Guide (left).
Confirming angulation with the direction indicator (center).
Placing the All-on-4® Guide for predictable positioning of implants (right).
Twist Drill in the posterior and placement of NobelParallel CC implant with TiUltra™ surface (left images).
Implant inserted until collar and implant inserted in the posterior (right images).
