ABSTRACT
Objectives
To assess the vertical discrepancy between implant-supported crowns and adjacent teeth in the maxillary anterior region at least 8 years after implant placement and to evaluate the influence of this discrepancy on the level of esthetic awareness of patients.
Material and methods
The sample consisted in 23 adult individuals evaluated at least 8 years after placement of an implant supported central or lateral single tooth fixed partial denture. Patients their crown delivered at a mean age of 47.8 years. Vertical discrepancy was measured by comparing initial and follow-up periapical radiograph using the implant as a stable structure. The satisfaction of the patients with their anterior teeth condition and the awareness of the possible vertical problem were evaluated using a questionnaire. The aesthetic outcome and patient awareness were related to the objective measurement of the vertical discrepancy.
Results
All implant showed a mean infra-occlusion of 0.62mm (range 0.15-1.63 mm). The vertical discrepancy was not associated to the patient’s gender, age at implant placement and duration between initial and recall radiograph. Patients were generally satisfied with the longterm aesthetic outcome of their smile (mean 3.9 on a 1-5 scale, 1 unsatisfied and 5 completely satisfied). Out of 23 patient 8 noticed the implant infraocclusion and only 4 of them found the problem severe enough to be willing to improve the situation. The amount of vertical discrepancy was not associated with the patient’s perception of the discrepancy.
Conclusion
Implant supported crowns in the anterior region may suffer infra-occlusion in the long term. The amount of vertical discrepancy was not dependent on gender and age of the patient. Patients were generally satisfied with the aesthetic result of the restoration. The amount of vertical discrepancy, at least in the range we have measured, was not perceived by the patients as a complication.
