The purpose of this study was to evaluate marginal bone level around single-tooth implants placed in anterior maxilla and immediately restored.
Materials and Methods
Twenty implants were placed in 20 patients (8 men and 12 women) that were selected for this study. Following atraumatic non-surgical extraction of tooth, all patients immediately received implants and the definitive prefabricated abutment was placed. Implant position was transferred to the scanning unit of the CAD/CAM system using prefabricated surgical guide. Temporary crowns were immediately fabricated and cemented.
Eight weeks later final crowns were luted. Outcome assessment as implant survival and level of marginal bone radiographic evaluations were performed at 8 weeks, 1 and 3 years time period after loading.
Results
All implants placed osseointegrated successfully after 3 years of functional loading.
The mean marginal bone loss was 0.16 mm (SD, 0.167 mm), 0.275 mm (SD, 0.171 mm) and 0.265 mm (SD, 0.171 mm) at 8 weeks, 1 and 3 years time period respectively. Four out of the 20 implants showed no bone loss.
Conclusion
Immediate loading technique using the final abutment directly eliminated the need for a second stage surgery and prevented interruption of soft and hard tissue at implant neck, which resulted in better soft tissue response and reduced marginal bone loss.
Clinical significance
Immediately loaded implants, in fresh extraction sockets by insertion of a provisional restoration on the titanium abutment without any later manipulation, helped to protect the initially forming blood clot and presented a template for soft tissue contouring that resulted in significant reduction of marginal bone resorption and maintenance of soft tissue architecture.
