Implant Placement Using Open Sinus Elevation Technique With and Without Bone Grafting Material

The success rate of dental implants after graftless sinus augmentation versus conventional sinus augmentation surgery in atrophic maxillae in edentulous patients was investigated and it was concluded that despite the bone gain in ten garftless side, implant survival were significantly lower in the non-grafted side. One year later, Lie et al., conducted a systematic review to evaluate efficacy of graftless maxillary sinus membrane elevation using the lateral window approach for implantation in the atrophic maxilla. It showed a high implant survival rate in non-grafted maxillary sinus lifts and conventional sinus lifts using augmentation materials and there was no significant difference in the ISQ values between both procedures. However, further randomized clinical trials with long-term follow-up were recommended.
