– Endosseous dental implants have been inserted into dog jaw bone following two different implantation principles. Using the two‐step procedure, the implant is left submerged, covered by the mucoperiosteum for a healing period, before communication with the oral cavity is established. According to the one‐step procedure, this communication is established peroperativcly. In order to estimate radiographically the degree of bone resorption following the two‐step as compared to the one‐step procedure, the former was used on the right and the latter on the left side of the mandible in two dogs. Periodic identical intraoral radiographs revealed bone resorption in the neck area of all implants. After a 1‐yr period with bilateral bridges, the vertical resorption varied between 3 and 5 mm. No difference was found between the two methods concerning this bone resorption. The observation seems to be contrary to the general opinion on the matter, and pertinent investigations with the present model will be performed in a human material.
