Abstract


Purpose: The present study was to retrospectively compare narrow diameter implants (NDIs) with regular diameter implants (RDIs) accompanying regenerative procedures in the atrophic maxillary anterior region.

Materials and Methods: The subjects were patients with NDIs (diameter ¡Â3.5 mm) and RDIs (diameter ¡Ã4.0 mm) placed in the atrophic maxillary anterior area from January 1st 2005 to December 31th 2009 at the Department of Periodontology, Dental Hospital of Yonsei University in Seoul, Korea. The cumulative survival rates were calculated. Also, the biologic and mechanical complications were examined as well.

Results: The survival rate of NDIs and RDIs were 96.67% and 98.60%, respectively, which did not reach a statistical significance. The rate of membrane exposure in RDIs was 23.94%. Further, no significant mechanical complications were observed in both groups.

Conclusion: Narrow diameter implants can be a good alternative for simplifying surgery and is therefore successfully used in the atrophic maxillary anterior region.
