Thank you for your good question and I will tell you in order.



(1) Press the stop condenser on the hatch reamer KIT and press it so that the osteotomy hole is clearly visible.

If insufficient, please allow enough for the reamer to contact the maxillary sinus membrane.

There is nothing harmful, but lack can be dangerous.

The reason I added spoon condenser to the express kit is because of the handling of the bone chip and the surrounding clearance.

 

(2) For 4.1mm diameter implants, there are differences depending on the implant length and the amount of bone remaining.

In case of 4.1 * 11mm, if remaining bone is 5mm, 3-4 times.

If the remaining bone is less than 5mm, it can be done 7 to 8 times by performing 3-4 more times because the maxillary sinus membrane needs to be safely secured for the first time before reaming.

In the 3mm lift case you mentioned, open the hatch and insert enough bone graft into the odteotomy hole.

Once the condensing is done, bone graft into the hole and the implant should be placed.

For a few minutes, the teacher shows a good result by opening the hatch and placing the implant directly without bone graft.

Many papers show the results of bone formation when implants are placed without bone graft after elevation of the maxillary sinus membrane.

Many use only PRF and the results are excellent.

 

(3) Osteotom shows difficulty in obtaining initial fixation of dense bone because fracture of maxillary sinus bone fails to obtain hole of desired size.

Therefore, in the soft maxillary remnant bone, there is also a role of compacton to harden the dense bone to obtain the initial fixation of the implant.

In this situation, the implantation of the bone chip in between and the failure of the implant due to impaired blood flow is not a common occurrence in osteotomy surgery.

Hatch reamers may be embedded with bone chips in the lateral maxillary bone marrow during the process of deleting dense bone at low speed, but they are only partially and have no compaction process.

It is no problem if the implant is placed without further action.

Was it helpful?

Thank you.
