ABSTRACT
Nineteen patients with either chronic adult periodontitis, advanced chronic periodontitis or rapidly progressive chronic periodontitis with teeth which, although retainable, were mobile, reduced in number, with large or posteriorly situated edentulous segments, had their treatment completed wlth full arch fixed bridges supported on the remaining teeth and standard Branemark implants. The 19 patients and their 61 implants were followed up for periods of 2-5 years affer the fitting of the permanent bridges, Bone loss after 2 years measured less than 0. 1 mm. Further loss occurred only slowly in those patients reviewed after 4 and 5 years. In this way, the remaining teeth, including the mobile ones which were kept, assisted in the carrying out of the treatment through to the fitting of the bridges. It should be noted that strict attention was given to the requirements of delaying the loading of the implants and the distribution of occlusal forces.

fig. 1. Rapidly progressive periodontitis. Four teeth with abscesses, 14,13, 11 and 21 which must be extracted. |

fig. 2. The teeth were extracted four months previously and replaced with a removable partial denture. The periodontal disease is stabilised. Note the severe Class I incisor overbite and the conditions predisposing to secondary occlusal traumatism. |
