The patient is controlled diabetic with fair oral hygiene but stable periodontal attachment for the last 7 years (He is my father).
Due to diabetes we proceeded with staged approach for the implant placement.
Extraction+socket graft and later implant placement
The design of the prosthesis:
The lab fabricates a PFM crown keeping access to the screw of the abutment
The abutment is sandblasted and the crown is cemented on the abutment with a permanent cement extra orally
Benefits:
1. Cost ( you use the abutment that comes with the implant)
2. Factory abutment has better fit on implant platform compared to a UCLA abutment
3. Avoid cement trap in cases with deep peri-implant sulcus. This could lead to peri-implantitis development
4. Easy access in case the crown needs to be removed for any reason
