Objective: The purpose of this study was to evaluate the effect of venting of implant abutment on the peri implant soft tissue response in cement retained restorations. Patients and methods: 14 titanium threaded implants were placed in 14 patients in the premolar maxillary area. 14 crowns were cemented over the abutments where 7 of the abutments were closed design while the other 7 were vented abutments. A three stage protocol was executed; surgical stage where the implants were placed followed by the prosthetic stage which included placement of abutments of two designs, CAD/CAM provisional crowns were then fabricated and cemented. In the follow- up stage; periodontal and soft tissue esthetic assessments were done at the time of provisional restoration placement (base line), then at 3months and 6months intervals. Results: Analysis of the results revealed that the effect of the abutment venting (vented and closed) on the peri-implant tissues was statistically insignificant between groups at baseline while significant at follow up intervals. Conclusion: Vented abutments showed better perimplant soft tissue results at follow up intervals. which seems to be strongly correlated to the less amount of excessive cement extruded in this group. Clinical significance: Vented abutments should be considered as an alternative to closed ones to decrease the amount of extruded cement for better perimplant outcomes.
