Core Tip

Core Tip: When the residual bone height is less than 5 mm, two-stage transcrestal sinus floor elevation is a safe technology, which might be an excellent option to embed standard-length implants. Two-stage transcrestal sinus floor elevation could obtain more maxillary sinus membrane elevation height, especially in difficult and complicated cases.
