Evaluation of 3- to 8-year treatment outcomes and success rates with 6 implant brands in partially edentulous patients.

The use of osseointegrated implants as a foundation for the prosthetic replacement of missing teeth has become widespread, with new dental implant systems being introduced every year. There is growing interest in identifying the factors associated with implant failure, such as implant type. This study was designed to establish the relationship between implant type and success. Eighty-eight patients (mean age, 52 years) with 268 implants (110 BioHorizons, 60 ITI, 60 Paragon, 18 Xive, six 3i, and 19 Allfit) participated in this 5-year retrospective study. Statistical significance was defined for P < .05. Peri-implant probing depth was associated with bone loss and bleeding on probing. Implant failure was not associated with implant brand. Maximal (or minimal) peri-implant probing depth and bone loss values were seen at anterior regions (or premolars). Maximal (or minimal) bleeding on probing was seen at the posterior (or anterior) region. No significant differences were observed between the different systems in terms of implant failure.
