Abstract

Aim

To present a technical note on intra-sinusal bone ring concomitant with Le Fort 1 osteotomy.

Material and method

A 57-year-old man was referred to our Department for full-mouth rehabilitation. Oral examination identified: uncompensated multiple tooth loss and a class 3 skeletal malocclusion. The treatment plan consisted in a Le Fort 1 osteotomy and short-arch dental implant rehabilitation. Intra-sinusal bone ring technique associated with Le Fort 1 osteotomy were carried out under general anaesthesia.

Result

High primary retention was clinically observed of both the implant and the bone graft. Radiographic follow-up demonstrated satisfactory healing of the graft and implant osseointegration.

Conclusion

Bone ring technique concomitant with Le Fort 1 osteotomy seems to be appropriate to correct jaw discrepancy associated to a single tooth loss of the upper molar region with residual bone height of at least 3 mm to ensure implant primary stability.
