Abstract
Aim: to compare between patient satisfaction and bone height changes of mini-implant supported overdentures in comparison with conventional implant after bone expansion technique.Methodology : This randomized clinical trial contains 36 edentulous participants with thin mandibular ridges randomly divided to receive 2 mini-implants, or 2 conventional implants after ridge splitting, both treatments were done in the inter-forminal area of the anterior mandible.Then the patients received mandibular overdentures with ball and socket attachments. At base line, after 6 and 12 months of loading the implants, patients{u2019} satisfaction was evaluated using Visual analogue scale, in addition to bone height changes using Soredex DIGORA Optime Classic software.Results: there was statistically significant difference in the overall satisfaction between the mini-implants and the conventional implants group, the amount of bone height changes in the mini-implant group was statistically significant less than the conventional implant group at base line, 6 and 12 months. Conclusion: Treatment with 2 mini-implants provides high level of satisfaction and less bone height changes in a follow up period of 12 months in comparison to using conventional mini-implants after ridge expansion
