The lady 58 years young wanted to change her look as her teeth were mobile in the mandible.

Her desire was also to receive a fast treatment out- come and not be without teeth.

Finance was also an aspect so we decided to do an overdenture.

Figure 2: Extraction was performed, bone was regularized and implants were inserted.

The choice of the implant was M 3514 which could be inserted between the extraction sockets in the remaining bone, initially, primary stability was brilliant, around 70 N/cm so all conditions were excellent to go for immediate loading.

4 implants were inserted and an impression with screwed transfers was taken immediately after the surgery.

After this, the transfers were taken out and analogues were delivered to the lab.

A temporary bridge was done chairside and cemented on transfers, we used TRM.

At the next appointment a week later we tried the key and fixed the occlusion.

At the next appointment, the milled barre in titanium was tried.

Inside the barre, the lab had used PCOM to get a perfect fitting to the implants.

Another week later the overdenture in peek was delivered the barre was screwed on the implants.

The same work can be done with ROOTT R implants but there I advocate going for delayed loading, 3 months.
You may do it with ROOTT C Implants:
The difference to ROOTT M implants is that getting the perfect fitting is more difficult and it may debond.
The screws are delivering very strong retention and as for this no debonding
Also a difference in price. The same prosthetic work with monoblock implants costs less ( lesser components).
So may also use P implants when bone quality is D3, D4 and you may mix ROOTT C , M, S, and P all depending finally on the bone quality.
