ObjectivesThe aim of this prospective clinical cohort study was to validate implant crowns with a novel Functional Implant Prosthodontic Score (FIPS).
Material and methodsTwenty patients were restored with cement-retained crowns on soft tissue level implants (Institut Straumann AG, Basel, Switzerland) in posterior sites and annually followed-up for 3 years. FIPS was applied for the objective outcome assessment including clinical and radiographic examinations. Five variables were defined for evaluation, resulting in a maximum score of 10 per implant restoration. The patients' level of satisfaction was recorded and correlated with FIPS.
ResultsAll implants and connected crowns revealed survival rates of 100% without any biological or technical complications after three years of loading. The mean total FIPS score was 7.81.5, ranging from 6to10. The variable bone revealed the highest scores (2 +/- 0;range: 2-2), followed by occlusion (1.9 +/- 0.1;range: 1-2). Mean scores for design (1.2 +/- 0.6;range: 0-2), mucosa (1.3 +/- 0.7;range: 0-2), and interproximal (1.4 +/- 0.4;range: 1-2) were more challenging to satisfy. The patients expressed a high level of functional satisfaction (84.1 +/- 9.5;range: 68-100). A significant correlation was found between FIPS and the subjective patients' perception with a coefficient of 0.88 (P<0.0001).
ConclusionsThe findings of the clinical trial indicated the potential of FIPS as an objective and reliable instrument in assessing implant success. FIPS can be considered as a supportive tool to validate a satisfactory outcome as perceived by patients, to identify possible failure risks, and to compare follow-up observations.
