Online published on 23 December, 2019. Abstract Purpose The aim of this study was to investigate the stability of three implants supported by a milled bar, which carries two different attachment systems and submitted to immediate loading. Methodology The current research was a prospective study conducted according to split-mouth design with random allocation of the tested attachments. Two types of attachments were used, OT Equator and OT Cap attachment. A total of 8 completely edentulous patients were divided into 2 Groups according to OT Equator position. CBCT was used for the planning and construction of the surgical stent. A milled bar with the attachments was fabricated prior to implant placement. Each patient received three implants in the interforaminal region, connected with a milled bar. On one side of the bar; OT Equator attachment was used, while the other side was supplied with OT Cap attachment. Overdenture was delivered at an average time of 10 to 15 days after implantation. Follow-up period was 12-months after loading. Implant stability was evaluated using Osstel TM. Results The results revealed that; there were no significant differences between all groups at implant placement time and at 12-months period for all implants and through different time intervals until the followup period was finished. Conclusion The results of the current study indicated an increase in implant stability and due to splinting of the implants by using immediate loading protocol. Splinting of the implants using a rigid bar appears to be a successful treatment option that could be considered for treating the completely edentulous patient.
