Qualitative Analysis of Maxillary Sinus after Guided Lateral Sinus Lift Procedure with Simultaneous Implant Placement

Aim: Evaluation of the lateral sinus lift technique using 3D-printed surgical guide with simultaneous implant placement. Subjects and methods: Using preoperative cone-beam computed tomography (CBCT) and a precise picture of the dentition, a surgical guide was created. Lateral sinus lift was performed by using a 3 dimensionalprinted surgical guide for lateral window osteotomy and implant placement. CBCT was obtained and maxillary sinus volume (MSV) was measured preoperatively, immediately postoperatively, and 6 months postoperatively. Implant stability (ISQ) using Osstell® was also assessed immediately postoperatively and 6 months postoperatively. Results MSV Immediate postoperative showed a significant decreased from the preoperative. Moreover, 6 months postoperative showed significant decrease from preoperative (p <0.001). Buccal showed a significantly more bone gain than palatal in immediate and after 6 months postoperative (P<0.05). A significantly increased bone density and ISQ six months postoperatively was reported compared to immediate postoperative bone density and ISQ (P<0.001). Conclusion: Lateral MS floor elevation using a 3D-printed surgical guide with simultaneous implant placement provides a faster operation and ensures predictable results, with superior sinus volume preservation, bone density, and ISQ.
