Abstract: The transalveolar technique for sinus floor elevation is a common surgical approach when there is insufficient vertical bone height in the maxillary posterior region for implant treatment. This article describes the evolution of this technique and the technical points of the clinical approach. It is very difficult to assess the intactness of the maxillary sinus mucoperiosteum in transalveolar technique when simultaneous bone augmentation is required. The use of electronic endoscope is a very helpful method to better confirm the preparation depth of the implant site and the status of the maxillary sinus mucoperiosteum, thus effectively avoiding complications of bone augmentation due to the maxillary sinus mucoperiosteum perforation. This article focuses on the clinical procedures and considerations in the use of transalveolar technique for sinus floor elevation to provide a reference for clinicians to improve the predictability of this technique.
