This intervention is frequently required for implant installation in the posterior maxilla, where the bone may be insufficient for securing implants of necessary length and stability. Sinus floor elevation can be completed either through a direct approach with a “window” through the lateral wall of the alveolar ridge or an indirect “transcrestal/transalveolar” sinus floor elevation (TSFE), which accesses the sinus floor through the crest of the edentulous ridge. Our study aims to provide a comprehensive scoping review of research conducted over the past 25 years on TSFE, specifically.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;A literature search aimed at identifying pertinent literature for the purpose of this PRISMA-ScR-compliant scoping review was conducted.

In the Control Group (CG, &lt;i&gt;n&lt;/i&gt; = 8), a xenograft was used in the inlay site and for the onlay site, a 1:1 mix of xenograft and an autograft was used. In Test Group 1 (TG1, &lt;i&gt;n&lt;/i&gt; = 8), both inlay and onlay sites were grafted with the xenograft associated with the micrografts derived from periosteum.

Implant site preparation was performed using a robotic system, and the total force (Ft) and axial force along the drill (Fz) during the surgery were recorded by the haptic robotic arm. The actual initial breakthrough point (drill contacting sinus floor) and complete breakthrough point (drill penetrating the sinus floor) were defined visually (the actual IBP and the actual CBP). The theoretical initial breakthrough point (the theoretical IBP) and the theoretical complete breakthrough point (the theoretical CBP) defined by the robot-guided system and the CBCT were determined by real-time force feedback and imaging distance measurement, respectively.
