Journal of Clinical PeriodontologyResearchers have found in a 10-year follow-up study that in edentulous patients with persistent maxillary denture complaints, similar, favourable outcomes are seen in bar-supported maxillary overdentures on either four or six anteriorly placed implants. The study has been published in the Journal of Clinical Periodontology.
A study was conducted to evaluate bar-supported maxillary implant overdenture treatment when supported by either four or six implants after 10 years.
Edentulous subjects with maxillary denture complaints and ample bone volume to facilitate implants in the anterior region of the maxilla were planned for implant overdenture treatment, randomized to receive either four implants (n = 25) or six implants (n = 25) and subsequently evaluated after 10 years of function. Outcome variables included peri-implant bone-level changes, implant and overdenture survival, complications, presence of plaque, calculus and bleeding, degree of peri-implant inflammation, probing depth and patient satisfaction. Differences between the groups and between evaluation periods were tested with a Student's t-test.
