Influence of Dental Implant Diameter on Implant Success

Abstract

Background: Missing teeth may result in a functional and cosmetic deficit and have traditionally been replaced with dentures or bridges.
Dental implants offer an alternative; they are inserted into the jawbones and used to support dental prostheses.
Objective: To relate diameter of dental implants with im- plant success.
Patients and Methods: Implants with a root form, conical morphology and internal hex design, with SLA (sand blast large grid acid etch)
surface treatment was used in this study. Two surgical procedures technique for submerged, bone level implants were used and 3 years
follow up after prosthetic procedure was done. The diameter was classified as narrow, regular, or wide. The statistics were computed
with Epi Info Version 6.
Results: In this study, 603 dental implants (312 maxillary and 291 mandibular) were placed in 285 patients (mean age, 45.23 years) involving
152 males and 133 females with 1.2: 1 male to female ratio. The 3 years survival rate for all 603 implants was 96.02%. The largest
success rate was observed in wide diameter implants (99%), followed by regular diameter (97.6%) and then narrow diameter (94.11%).
According to Epi Info Version 6 analysis the chi2= 7.6 and P- value= 0.03 associated with 3 years follow up.
Conclusion: According to this study there is relationship of implant diameter with success rate.
Key words: Dental implant, implant diameter, implant success.
