RESEARCH Evaluation of 3- to 8-Year Treatment Outcomes and Success Rates With 6 Implant Brands in Partially Edentulous Patients Amir Moeintaghavi, DDS, MSc1* Mehrdad Radvar, DDS, PhD1 Hamid Reza Arab, DDS, MSc1 Hamid Reza Boostani, DDS, MSc2 Elham Ghiami, DDS3 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. Key Words: dental implant, success, failure INTRODUCTION he science of implantology is progressing rapidly, with new systems being presented every year. The replacement of missing teeth with dental implants has become an acceptable standard of care over the past several decades.1,2 Functional and esthetic physiological outcomes and psychological benefits have been reported for the use of implantsupported fixed partial dentures (FPDs) in patients who object to removable partial denture (RPD) use.3–5 The success rate of implant prosthetics is Dental Research Center, School of Dentistry, Mashhad University of Medical Sciences, Mashhad, Iran. 2 Department of Periodontics, School of Dentistry, Mashhad University of Medical Science, Mashhad, Iran. 3 Private practice, Mashhad, Iran. * Corresponding author, e-mail: DOI: 10.1563/AAID-JOI-D-10-00117 1 T higher than that of natural teeth–supported traditional prostheses.4,5 Compared with tooth-supported cantilever FPDs, implant-supported FPDs for the treatment of distal extension base situations are less prone to problems.3–5 Different risk factors can negatively affect implant longevity. Anatomic features, mastication dynamics, and adequate implant selection are all significant for long-term implant prognosis.6 Implant design features such as macro- and micro-design may influence overall implant success. Limited information is currently available. Appraising the current literature on this subject and combining existing data to verify the presence of any association between the selected characteristics may be critical in the achievement of overall implant success.7 Research on new macrostructures and nanomorphology should result in a better qualitative and quantitative osseointegration reJournal of Oral Implantology 441
