Lateral nasal wall lift using trap door technique - a new method for the severely atrophic maxilla
Lateral nasal wall lift using trap door technique - a new method for the severely atrophic maxilla
A new method for single-stage augmentation and implant placement in the severely atrophic edentulous maxilla is to be presented. The combination of an extremely deficient bone volume in the anterior maxilla and an extremely narrow maxillary sinus in the lateral maxilla in the transverse direction makes implant placement impossible or results in prosthetically unusable implant axes despite the sinus lift. Through an additional trap door displacement of the lateral wall of the nasal cavity combined where required with an anterior inferior turbinectomy, simultaneous insertion of 3 XiVE implants on both sides is enabled in this scenario.
Thus, even with an extremely unfavourable initial scenario, a well-supported fixed implant prosthetic treatment is usually possible on an out-patient basis with comparatively little effort and just one surgery.
The difficulties and the surgical procedure shall be discussed by means of a case study. Three different lateral nasal wall lift variations for different initial anatomical scenarios are to be described. The advantages of the relatively low impact procedure shall be discussed in comparison with the more complicated onlay bone grafting or Le Fort I osteotomies with interpositional bone grafting
