Bone-implant interface structures after nontapping and tapping insertion of screw-type titanium alloy endosseous implants.
To compare different surgical insertion procedures, histologic and histometric studies were made on the structure of the interface between jaw bone and implants in two monkeys. Two materials were tested; TiO2 coated and noncoated, screw-type titanium alloy endosseous implants. All implants by tapping insertion were healed with direct bone apposition whereas implants by nontapping insertion revealed some degrees of fibrous connective tissue intervention between bone and implant. No difference was found between TiO2 coated and non-coated materials.
