I'm at D3 at UoP. I can remember asking specifically about the amount of writing when I was interviewed by a student. They said there wasn't much writing at all. Well... While this isn't much writing, it was more than I expected.
In D1 we had a few group PowerPoint presentations for case based discussions. We also had to do a case presentation on a fictional patient. D2 included a group microbiology lab report, a case presentation on one of your clinic patients, 4 clinic reflections with EBD. D3- 3 more EBD clinic reflections, a group paper with EBD, case presentation on clinic patient, and group project for practice management.
Additional case presentations are made in front of reconstructive faculty and oral surgeons for treatment planning when you have patients that need anterior implants, and other complex implant restorations.
