Background:
There have been numerous reports evaluating clinical outcomes of implants placed in institutional settings, but there are few studies relating to implants placed in private practice. The aim of this retrospective study was to analyse the clinical outcomes of 1000 consecutively placed Straumann implants in private specialist periodontal practice.
Methods:
A hand-search of patient records was undertaken to identify 1000 consecutively placed implants. Data extracted included patient demographics, details of implants placed, implant sites, timing of placement after extraction, hard and soft tissue augmentation procedures, loading protocols, type of prostheses and treatment outcomes (implant survival, implant success and complications).
Results:
The majority of implants (71.5 per cent) placed in patients aged 40 to 69, and the majority of patients (88.6 per cent) received 1 or 2 implants. During the period of the study, 9 implants were lost and 45 presented with complications requiring chairside intervention. A life table analysis showed 5 and 10-year cumulative survival rates of 99.2 per cent and 98.4 per cent respectively, and 5 and 10-year cumulative success rates of 93.1 per cent and 90.9 per cent respectively.
Conclusions:
With careful treatment planning and adherence to recommended surgical and prosthetic protocols, high implant survival and success rates can be achieved in a private practice setting.
