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.

KEY WORDS:

 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.

 Clinical photograph. The choice of implant sites depends upon the anatomical conditions and
 functional needs.  The bone condition did not permit an implant at 21. It was replaced by 24.
