Information regarding the influential factors on selection of implant treatment by patients was collected using a valid and reliable questionnaire, and the correlation of influential factors with outcome satisfaction was analyzed by the Pearson and Spearman correlation tests. Data were analyzed by independent t-test, Kruskal-Wallis test, Mann-Whitney test, Chi-square test, and one-way ANOVA (alpha=0.05).&nbsp; <b><span style="color:#2e74b5">Results: </span></b>Advice from dentists was the most common reason (50.4%) for selection of implant treatment. Knowledge of patients about implant treatment had a significant correlation with their outcome satisfaction (P=0.003) but had no correlation with dental clinician&rsquo;s satisfaction with the treatment outcome (P=0.054). Knowledge of patients about implant treatment had a significant correlation with the time interval between the date of advice from their dentist and time of seeking dental implant treatment (P=0.024), and their level of education (P<0.001).<span style="font-family:&quot;Verdana&quot;,sans-serif"></span> <b><span style="color:#2e74b5">Conclusion:</span></b> Patients had optimal knowledge level about implant treatment, and dentists had the most important role in knowledge enhancement of patients and convincing them to seek dental implant treatment. Knowledge level of patients had a significant correlation with their satisfaction with the outcome. &nbsp; </span></span></pre> Dental Implants, Patient Satisfaction, Knowledge 100 109 http://jrdms.dentaliau.ac.ir/browse.php?a_code=A-10-1303-1&slc_lang=en&sid=1 Kiarash Asadollahi kiarash.a1993i@gmail.com 100319475328460012313 100319475328460012313 No Private Dental Practice, Isfahan, Iran.
