This study aimed at analysing the radiographic changes around the distal implants of implant-supported fixed complete dentures (IFCDs). 63 digital periapical radiographs were taken at prosthesis installation, after 1  and 3 years of functional loading. Radiographic data were collected by means of gray levels and texture analysis parameters. Maximum bite force, bruxism, dental arch, use of provisional prostheses and time of functional loading were analysed as possible factors responsible for the alteration in density around the implants. A hierarchical linear regression of mixed effects tested the relation between radiographic data and clinical factors over time. There was an increase in radiographic trabecular bone density around the distal implants of IFCDs.
