A qualitative and quantitative histological study of the initial healing response adjacent to 24 submerged and non‐submerged implants placed in the lower jaws of 6 monkeys is presented. The histomorphometric analysis showed no significant differences in mineralized bone‐implant contact length between submerged and non‐loaded non‐submerged titanium implants. The infrabony defects around some of the implants on the radiographs were significantly correlated to the histological measurements. Qualitatively, a greater number of gingival inflammation cells and a longer junctional epithelium were seen adjacent to non‐submerged implants without oral hygiene than were seen adjacent to non‐submerged implants with oral hygiene in the initial healing period.
