To evaluate the efficacy of osseodensification on primary stability and final osseointegration of implants placed in D3 and D4 type of bone

Aim

To evaluate efficacy of osseodensification on primary stability and final osseointegration of implants placed in areas of compromised bone density.

Material and methods

Study population comprised 10 patients, having D3/D4 type of bone. A total of 24 implants were placed in mandible and maxilla. The evaluation was carried out periodically for 1 year, investigating the influence of osteotomy technique using densah bur on clinical and radiographic parameters namely assessment of implant stability using torque wrench and osstell device, measurement of bone gain, bone expansion, bone density, bone surface area and crestal bone loss.

Results

The statistical analysis of torque wrench values at T0′ was 37.50(3.54SD) and 51.00(3.16SD) at T6 with p-value<0.001. The ISQ reading at T0′ was 62.8(3.4SD) and at T6 it was 65.8(5.4SD) p = 0.15,no significant difference seen. Considerable amount of bone gain post operatively noted (approx 26.8 %)p < 0.001. Evaluation of bone expansion in terms of ridge width demonstrated increase post-op(p < 0.001). Analysis of bone density in HU reveals significant increase at T6 p < 0.001. Bone surface area data tabulated at different intervals suggest increase post-op and at T6 (p < 0.05). The statistical data of crestal bone loss calculated periodically revealed 1.38 ± 0.41 at 12 months(p < 0.05).

Conclusion

Osseodensification using the versatile densah bur is a paradigm shift in the osteotomy preparation.
