Characteristics and frequency distribution of bone defect configurations in peri-implantitis lesions-A series of 193 cases.

ABSTRACT:

Background

Knowledge on peri-implantitis bone defect characteristics and predictors is still limited.

Purpose

To describe peri-implantitis bone defect characteristics and identify possible predictors.

Methods

Various parameters at patient- (age, gender, smoking, and supra-structure), implant- (surface, type, connection, platform, and misfit), and site level (region, alveolar ridge position, defect characteristics, neighboring structure) were recorded retrospectively.

Results

Among 193 implants, the most prevalent defects were class Ic (25.4%), and Id (23.8%); a previously non-described category "class Id with only one bone wall" was frequently observed (11.9%). Mean intrabony defect depth and width ranged from 4.5 to 6.2 mm and from 2.7 to 2.9 mm, respectively;
