8 titanium implants (Nobel Biocare, Göteborg, Sweden) were inserted into edentulous lower premolar areas of 4 dogs so that 6 threads of the implant protruded from the bone crest. Newly‐developed perforated dome‐shaped titanium space maintainers were fixed to the implant with cover screws. Autogenous bone fragments were placed under the space maintainers. On one side of the arch, the space maintainer was covered with a non resorbable cell occluding barrier. The implant/space maintainers were submerged under coronally postitioned flaps. Following a 3‐month healing period, there was a mean gain of new bone amounting to 2.5mm for all specimems. A greater height of bone was found for those sites in which an e‐PTFE membrane was used; 3.1mm vs. 1.9mm ( p <0.05). This study demonstrated the potential of coronal bone growth of the alveolar bone in a protected space around screw implants with exposed treads when placed in the dog.
