Objective There is a need for quality assessment regarding to implantology within the Centre of Dentistry and Dental care (CDD) in a period of seven years (2011-2018). The aim of this study is to evaluate the survival of SSC’s in patients treated within the CDD on the basis of a maximum of 7 years old data from the patient file. With the data from the implants that did not survive this period, an attempt will be made to find out why the implants have failed, whether this is in accordance with the literature and what the risk factors are to improve the quality regarding to implantology within the CDD. The main research question is: “What is the 5-year survival rate of titanium implants combined with screwed single unit crowns (SSC’s) for replacing missing teeth in patients within the CTM?” Moreover, the sub-question: what risk factors are associated with failure of titanium implants in combination with SSC’s? Materials and Methods The number of implants that were included in this study was 361. Kaplan-Meier analyses were performed for the 5-year survival rate of titanium implants in combination with screwed single unit crowns. The results of the expected 5-year survival of 97% is compared with literature. Cox regression analysis was used to detect the factors influencing implant failure. Results Of the 361 implants, 15 of them have failed during the follow-up period. These implants are 7 from Straumann, 3 from Astra and 5 from Nobel Biocare. The 5-year survival rate was 96.8%. Implant brand was the only variable with a statistically significant effect on survival. The 5-year survival rate of Straumann implants was 97.8%. For Astra implants the 5-year survival rate was 93.8% and for Nobel Biocare 92.5%. Conclusion The 5-year survival rate of titanium implants for single crowns in this study is 96.8%. This is in line with the literature. There is a statistically significant effect of implant brand on survival. Straumann implants have a greater chance of survival than Nobel Biocare implants. Little research has been done in the differences in the three implant brands. Based on the results, it is recommended to continue using Straumann implants and better not to use the Nobel Biocare brand implants within the CTM until the cause of the failure has been determined. However, there is need for more research in differences in A-brand on the survival of SSC’s. This way we can make a thorough choice in the future when it comes to the type of implant brand.
