Indirect Sinus Lift
Patient Profile: Patient is a 68-year old retired male who presented with a missing upper right first molar space. He wishes to explore treatment options to restore the missing space.
Chief Complaint: “I miss the upper right molar when eating and find I am eating constantly on the other side. I’m concerned I may fracture another tooth on the left side and need an extraction”
Dental History: His last dental appointment was to remove the fractured non-restorable upper right first molar.
Medical History: The patient reported several stents placed four years ago without complication. He was medicated on Nu-seal, an anti-hypertensive and a statin. Most recent cardiology review was favourable. ECG normal. Cardiac echo was normal with favourable ejection fraction. His blood pressure was recorded at 135/85 mm/hg and recent bloods were all within normal limits.
Extraoral Examination:
- Assessment reported all within normal limits.
Supplemental Information:
- There is not enough vertical bone height to facilitate routine dental implant treatment.
- The socket is three months post-extraction.
- The solution will require bone grafting in the form of an indirect sinus lift.
- This involves bone chips (Creos particulate graft) placed into the floor of the sinus with simultaneous implant placement.
- The implant and graft are left 4/6 months to covert to bone (ossify) and fuse together (osseointegrate)
- Implant placement is under local anaesthesia with IV sedation.
- A digital scan is taken after 4/6 months and the crown is screwed onto the implant and is permanent.

“I was concerned that I would not be able to have the dental implant option given the lack of bone height. The bone graft procedure for me was preferable to having my adjacent teeth drilled down to stumps to fit a dental bridge. I found the entire procedure very straight forward with very little discomfort afterwards. A big thank you to everyone at the Castle Clinic”.
