Paradigm Shift in the Management of the Atrophic Posterior Maxilla

Figure 2

CBCT exam at 5 years. Note the absence of Schneiderian membrane thickening on the coronal view of implant placed with grafting material (right sinus, second molar site) and without grafting material (left sinus, second molar site). The CBCT confirms that the implant in the left sinus protruded into the sinus whereas the implant in the right sinus was completely embedded in peri-implant bone.
