Azhar Kharsa Ph.D. Orth. commented that *only* osseointegrated implants can or should be used for orthodontic anchorage. The only response that comes to mind is.....rubbish! There is adequate evidence from animal research and clinical application that non-integrated anchors are efficacious and certainly more cost-effective than osseointegrated implants UNLESS the osseointegrated implants are subsequently used for prosthetic replacement of a missing tooth/teeth. If Dr. Kharsa has evidence or experience to the contrary, I suggest that it be presented for scrutiny. Otherwise, the statement is mearly personal opinion.

I've been using the Canon 300d with the 18-35mm lens that it came with for about 9 months with good results.  We take all our pictures using the manual (M) setting.  The shutter speed is 60 for all shots.  The intraorals we use f22 and extraorals f5.6.  We switch from manual focus for intraorals to auto focus for extraorals.  Because the flash is above the lens, moving the camera to below the occlusal plane for the buccal shots helps with the shadow from the upper part of the check retractor.  It takes some practice to take occlusals without distracting shadows.  Please give me a call if you have questions.
