Thought I might share a recent case. Patient is a healthy adult male, non-smoker. He is fed up with mobile broken down dentition. Three weeks prior to surgery, I injected Dysport [abobotulinumtoxin A] into his Temporalis and Masseter muscles. Alginates were taken to create full immediate dentures which would be converted to screw-retained temps on the day of surgery. I have an in-house lab technician to help with the conversion.
Day 1 maxillae: To help with Pterygoids I used a pilot drill guide made by MIS Implants in their implant center here in Israel . Patient does not receive teeth at end of day 1 .
Day 2 mandible: Extractions and implant placement. Impression for creating model used by technician to retrofit the immediate denture to a screw retained acrylic temp. At end of day 2 deliver both screw retained temps.
Update: Here is another case. 9-yr old classic All on 4.
