Comparison between Osseo densification burs and osteotome technique for closed sinus lift in partially edentulous maxilla (clinical and radiological study)

Abstract

Dental implants are considered the first choice to replace lost or non-restorable teeth. However, the posterior maxilla remains a challenge in its management because of the quality of bone in the posterior maxilla. Osseo densification (OD) concept has been proposed in the literature to improve primary implant stability, which is an important aspect of osseointegration. Densah bur is novel drills specially designed to enhance a bone density by Osseo densification, which in turn increases primary stability. This present study was conducted to assess crestal sinus floor elevation by osteotome in comparison to Densah bur in the posterior atrophic maxilla. This was a randomized controlled clinical trial conducted on 20 patients to evaluate available crestal bone height loss, implant stability after implant placement in healed posterior maxillary alveolar ridge, whole bone height, Schneiderian membrane trauma, and post-operative complication.

Effect of Different Crestal Sinus Lift Techniques for Implant Placement in the Posterior Maxilla of Deficient Height: A Randomized Clinical Trial

“…However, our finding contradicts other studies that reported no significant difference concerning primary stability between the Densah and osteotome techniques [32,33]. Secondary stability measured after 6 months shows a statistically significant difference in the mean implant stability measurements among the three groups; again, Densah has the highest mean implant stability, which is in agreement with previous results [32,34]. On the other hand, the results were also compared with those of another study [24,33], which reported no statistically significant difference between the piezosurgery and osteotome techniques; both showed lower mean implant stability measurements that were statistically significant.…”

“…This finding is similar to those of other studies [30,31] that demonstrated the highest implant stability to characterize the Densah group. However, our finding contradicts other studies that reported no significant difference concerning primary stability between the Densah and osteotome techniques [32,33]. Secondary stability measured after 6 months shows a statistically significant difference in the mean implant stability measurements among the three groups; again, Densah has the highest mean implant stability, which is in agreement with previous results [32,34].…”
