Although clinicians routinely aim to provide a prosthesis with an accurate fit on implants, a degree of prosthesis misfit is inevitable. This exploratory pilot animal study evaluated the effects of framework vertical misfit and the timing of implant loading on implant position and screw loosening. Four implants were placed in healed ridges of each side of mandibles of 3 sheep. On the right side, 2 immediate frameworks were placed after 2 days. One framework was fitting, and the other one had a vertical gap of 0.5 mm on the distal implant. After 8 weeks (first review), the left side received 2 conventional frameworks with similar fit conditions to the right side. All animals were euthanized a..View full abstract
