Should you screw retain or cement retain your dental implant crown?
Screw retain vs cement retain for a dental implant really depends on doctor preference. Experience of the dentist is far more important than which you choose IMHO.
Screw v cement dental implant research
Results of a systemic review on screw retain vs cement retain dental implants JPD 2016 Lemos
- Cement retained have less bone loss
- Cement retained have fewer prosthetic complications
- Cement retained have more favorable survival rates
Not what I would have expected.
Wonder how a screwmentable crown would do? By that I mean one that has separate crown and abutment that has crown cemented on in the mouth but has screw access so is removed to clean cement and then replaced.
When should we splint he crowns of a dental implant?
Another one of those controversies that are unclear. Reasons to consider splinting are
- Tall implant crowns, which result from significant bone loss and are thus also often on short implants. No perfect number but crown/abutment height of 15 mm is tall and anything > 10 mm consider.
- Smaller diameter implants, especially those replacing molars. 4.0 mm diameter and under is narrow and can lead to more prosthetic complications.
- Bruxers and anyone with occlusion that results in lateral forces (although should just eliminate those)
- Although not common any more, any external hex implant
