Prevalence of Peri-Implant Mucositis and Peri-Implantitis in Patients Treated with a Combination of Axial and Tilted Implants Supporting a Complete Fixed Denture

Abstract EN

Objectives.

The aim of this retrospective study was to assess the incidence and prevalence of peri-implant mucositis and peri-implantitis in patients with a fixed full-arch prosthesis supported by two axial and two tilted implants.

Materials and Methods.

Sixty-nine patients were included in the study.

Each patient received a fixed full-arch prosthesis supported by two mesial axial and two distal tilted implants to rehabilitate the upper arch, the lower arch, or both.

Three hundred thirty-six implants for 84 restorations were delivered.

Patients were scheduled for follow-up visits every 6 months in the first 2 years and yearly after.

At each follow-up visit peri-implant mucositis and peri-implantitis were diagnosed if present.

Results.

The overall follow-up range was from 12 to 130 months (mean 63,2 months).

Three patients presented peri-implantitis.

The prevalence of peri-implant mucositis ranged between 0 and 7,14% of patients (5,06% of implants) while the prevalence of peri-implantitis varied from 0 to 4,55% of patients (3,81% of implants).

Conclusions.

The prevalence and incidence of peri-implant mucositis and peri-implantitis are lower than most of the studies in literature.

Therefore this kind of rehabilitation could be considered a feasible option, on the condition of adopting a systematic hygienic protocol.
