| Popis: | Objective This study was performed to establish an optimized beagle model for maxillary sinus floor augmentation via a mini-lateral window with simultaneous implant placement. Methods Twelve beagles underwent maxillary sinus floor augmentation via a mini-lateral window with simultaneous implant placement through sites selected by analyzing preoperative cone beam computed tomography (CBCT) images. During the experiment, no maxillary teeth were extracted and the infraorbital nerve was not severed. The osteotomy was only 5 mm in diameter. The implant stability quotient was measured, and postoperative CBCT was used to detect the condition of the sinus membrane and bone augmentation. Results The site corresponding to the tip of the highest dental cusp of the maxillary fourth premolar was suitable for the procedure, and the implant site was on the palatal bone plate. All implants achieved good primary stability. Postoperative CBCT showed no sinus membrane perforation, and the implants penetrated into the sinus cavity surrounded by bone substitute. Conclusion The herein-described optimized model with mini-lateral osteotomy and without extraction or severing of the infraorbital nerve was minimally invasive, retained more lateral bone of the sinus, and achieved good sinus floor-lifting results. This model is highly reproducible and merits wider application. |
