A randomized controlled clinical trial of conventional and immediately loaded tapered implants with screw-retained crowns.
OBJECTIVE
Surgical, prosthodontic, and esthetic outcomes of conventional and immediately loaded, single, tapered, roughened-surface Southern implants in the anterior maxilla that were restored with screw-retained crowns were compared over 1 year.


METHODS
Standardized surgical and prosthodontic procedures were followed and accepted criteria were used for assessment.


RESULTS
There were no significant differences within or between the control and test groups for age, gender, bone quality or quantity, implant stability measurements at surgery, or implant length.


CONCLUSIONS
After 1 year, the implants that had been immediately loaded with single provisional crowns at surgery and definitive crowns 8 weeks later were as successful as conventionally loaded 2-stage implants.
