Assessment of the survival of a single implant-supported cantilever prosthesis in the anterior mandible

Abstract

Background: Implant dentistry has seen rapid and remarkable progress in recent years. The present study assessed the survival of a single implant-supported cantilever prosthesis (ISCP) in the anterior mandible. Materials and Methods: Sixty-four patients with missing mandibular anterior teeth of both genders were provided with a single implant and restored with cantilever screw-retained prosthesis. All were followed for 2.5 years for the implant and prosthetic success. Results: Age group of 20–30 years comprised 14 males and 10 females, 30–40 years had 10 males and eight females, 40–50 years had six males and seven females, and 50–60 years had four males and five females. The difference was nonsignificant (P > 0.05). A screw loosening was seen in total of 15 cases, in 1 at 12 months, 5 at 18 months, 2 at 24 months, and 7 at 30 months, and porcelain fracture was seen in total of eight cases, in 4 at 18 months, 1 at 24 months, and 3 at 30 months. The difference was statistically significant (P < 0.05). Conclusion: Screw-retained ISCP developed complications such as screw loosening and porcelain fracture.
