A retrospective analysis of early implant failure of the Adin Touareg –X dental implant system Mogammad Thabit Peck, 1 Asim Satti, 2 Abdul Majeed 3 Introduction Dental implants have become a popular the treatment of choice for the management of edentulous sites, and in many cases have become the standard of care, this is mainly due to the ability of modern dental implants to successfully osseointegrate [1]. Dental implants are however not without complications and in a number of cases may not osseointegrate after placement. This is termed early implant failure (EIF) [2]. Many reasons have been suggested for EIF, however no single reason has been identified as a consistent causative factor [2-4]. Dental implant manufactures have sought to enhance the success rate of osseointegration by modifying dental implant surfaces by both chemical and physical means [5,6]. This has been shown to enhance osseointegration when compared to non-modified surfaces [6]. Variation in surface modification techniques exist, with many dental implant manufacturers producing unique surfaces on their implants. It has been postulated that these differences contribute to the range of osseointegration success rates seen from various manufactures [6]. The aim of this study was to investigate the early failure rate of a dental implant system with a calcium phosphate (CaP) modified surface. Materials and Methods Patient’s files from a dental teaching centre were analysed for the required data. All patients who had undergone implant placement using the Adin Toureg-X dental implant system (Adin Dental Implants Systems ltd., Afula, Israel) either for single or multiple missing teeth were included in the study. A single-experienced peridontist placed all the implants. The surgical protocol for each placement was standardised. The following groups of variables were recorded from the file for each patient; IJCDS • OCTOBER, 2014 • 5(2) © 2014 Int. Journal of Clinical Dental Science ABOUT THE AUTHORS 1.

Because the current literature is sparse with regards to this phenomenon, a retrospective analysis of EIF for a novel dental implant system was carried out. Materials and methods: Data was collected from files of patients being treated at a dental teaching institution. Patient, implant and surgical variables were collected and analysed statistically. Results: 29 implants placed in 13 individuals with a mean age of 49.7 years. Survival rate was 92% among healthy patients and 75% among patients with co-morbidity. All implant failures were amongst patients with type 3 bone. Implants with a diameter of 3.5 mm and less recorded a survival rate of 87.5% and implants with a length of 10 mm and less recorded a survival rate of 90.9%. Conclusions: The presence of co-morbidity, implant diameter and bone quality affect the osseointegration success rate of the current system. Previous studies indicate that the unique implant surface on this system may contribute to enhanced healing in the early phases. Further research is required to substantiate these initial clinical results in a larger sample. Keywords: Dental Implants, early implant failure, osseointegration 30 RESEARCH
