Abstract

Background: To date, no clinical investigation has assessed the clinical and radiographic indices around narrow diameter implants (NDIs) and regular diameter implants (RDIs) in individuals with cigarette smoking habit and nonsmokers.

Objective: To estimate and compare the clinical and radiographic indices around NDIs (< 3.3 mm) and RDIs placed in cigarette smokers (CS) and nonsmokers (NS).

Materials and methods: Eighty-six patients requiring implant surgery in the anterior mandible were divided into two groups (39 CS and 43 NS). Patients were further categorized into two subgroups on the basis of implant diameter: (a) patients with NDIs (3.3 mm) and (b) patients with RDIs (4.1 mm). Clinical indices evaluating plaque index (PI), bleeding on probing (BOP), and probing depth (PD) were recorded at 18 and 36 months of follow-up. Digital periapical radiographs were studied to evaluate crestal bone levels (CBL) incorporating in a specialized software and examined on a calibrated computer display screen with the help of an image analyzer.

Results: The mean age of patients in CS group and NS group was 44.6 and 42.5 years, respectively. There was no statistically significant difference in the overall mean scores of PI, PD, and CBL around NDIs and RDIs among CS and NS patients at 18 and 36 months of follow-up. However, there was a statistically significant difference only in the overall mean BOP around NDIs and RDIs among CS and NS patients at 18 and 36 months of follow-up.

Conclusion: The findings of the current study suggests that NDIs can show reliable clinical stability and radiographic bone levels as RDIs placed in CS and NS, with the support of strict oral hygiene protocols.

Keywords: cigarette smoking; crestal bone levels; narrow implants; periimplant inflammation.
