Implant Systems Used in a Teaching Hospital - A Retrospective Analysis

Introduction: Dental implant therapy is one of the best treatment modalities for restoration of the missing teeth. It's been available as a treatment option for more than over thirty years. There are many types of implant systems available and clinicians are facing the dilemma of choosing an implant system from a large number of options. The main goal of modern dental treatment is to restore the patient's normal function, speech, esthetics, as well as health. Aim: The aim of this study was to evaluate the different types of implant systems used and most commonly employed implant systems in replacing the missing teeth among the patients attending a teaching institution. Materials and Methods: Case records of patients who underwent implant placement were retrieved. A total number of one thousand one hundred and twenty eight implants were placed in five hundred and eighty five patients with a mean age of 39.9 ± 12.5. Descriptive statistics such as frequency, percentage and chi square test was done for association. Results: The common implant site was found to be mandibular posteriors. There were three implant systems used namely, Equinox, Nobel Biocare and Straumann; under nobel biocare and straumann there were different types of implants used. Majority of the implants placed were from the nobel biocare system 45.12%. Association between age, site of implant placement with implant systems showed statistical significance(P<0.05) while association between gender and implant systems did not show any statistical significance(P>0.05). Conclusion: Within the limitations of this study, the most common implant system used to replace the missing teeth of the patients who attended a teaching institution was found to be Nobel Biocare, in which male patients were mostly treated with dental implants and mandibular posterior teeth were the most common site of implant placement. Clinical Significance: Nobel biocare is the most preferred implant system in the hospital where a majority of the patients were males.
