Clinical Case Video
Implant Placement with Simultaneous Sinus Floor Elevation (Lateral Window Technique)
Surgical treatment of a 68-year-old female patient who experienced failure of her conventional bridge in the right maxilla. After removal of the compromised abutment teeth and a healing period of 6 weeks, a sinus floor elevation procedure using the lateral window technique and a composite graft to correct the insufficient bone height is carried out.
Two dental implants are placed in the same surgical session. The case concludes with the presentation of the final fixed dental prosthesis with a distal cantilever unit.
The 1-year follow-up radiographs demonstrate successful sinus floor elevation and stable bone crest levels around both implants, leading to a favorable long-term prognosis of the implant-supported prosthesis.

* General SAC assessment modifiers that are also part of the ERA. To avoid redundancy they are listed in this section even if no complete ERA has been made.
** Not applicable to the ERA of immediate placement cases and replaced by "Socket Integrity" listed below under "Surgical SAC Classification". For all other placement types this value is a classification determinant and listed here even if no complete ERA has been made.
