Bone grafting helps restore favorable volume and shape to jawbone sites receiving dental implants. To ensure patient comfort, Ardentis specialists in implantology and oral surgery offer highly minimally invasive bone augmentation procedures. These treatments are gentle, accessible, and meet modern dentistry’s standards for reliability, predictability of outcomes, shorter duration, and cost-efficiency. The techniques used are featured in peer-reviewed international scientific journals.
Two new high-impact international publications have just been released. Both stem from a clinical study conducted by Ardentis specialists. The study focuses on comparing implants placed in atrophic maxillae with and without grafting material using the osteotome sinus floor elevation technique.
Frequently Asked Questions:
-
Are implants placed in grafted and non-grafted sinuses equally stable?
-
What about the crown-to-implant ratio and prosthetic restorations in maxillae with very limited bone height?

“Stability evaluation of implants placed in the atrophic maxilla using osteotome sinus floor elevation with and without bone grafting: A 5-year prospective study.”
International Journal of Oral Implantology 12(3):337–346, 2019.
This article evaluates the 5-year stability of implants placed using the sinus-osteotome technique. It shows that implants placed in non-grafted sites are just as stable as those in grafted sites.
-
At the time of surgery, mean stability was 58.9 ± 11.2 ISQ in the grafted group vs. 53.8 ± 10.2 ISQ in the non-grafted group.
-
After 5 years, these values increased to 80.8 ± 4.2 and 79.8 ± 4.3 ISQ, respectively.
Second Publication

“Change in crown-to-implant ratio of implants placed in grafted and nongrafted posterior maxillary sites: A 5-year prospective
randomized study.”
The International Journal of Oral and Maxillofacial Implants 34(5):1231–1236, 2019.
This article addresses questions surrounding crown-to-implant ratios and prosthetic restoration outcomes:
-
A high initial crown-to-implant ratio, due to limited anchoring bone height, does not compromise long-term implant survival—regardless of whether grafting material is used.
-
The mean crown-to-implant ratio was 4.2 at the time of crown placement and improved to 2.1 after 5 years, due to increased endo-sinus bone height along the implant body.
-
Only one prosthetic complication was reported among 35 single-unit restorations.
