Aim of the study (i) To evaluate the survival and success rates of the new Roxolid narrow diameter implant placed in horizontally deficient ridges; and (ii) to evaluate the incidence of prosthetic complications. Materials and methods In a 24‐month period (2009–2010) 18 partially or totally edentulous patients received 51 Straumann Roxolid (13 tissue level, 38 bone level) implants. Prosthetic loading of implants was either immediate (four implants; one patient) or delayed (2–12 months after placement; 47 implants; 17 patients). The patients were rehabilitated with either fixed (16 patients; 45 implants) or removable (two patients; six implants) prostheses. Results All implants successfully achieved osseointegration and all patients completed the planned prosthetic rehabilitation. Peri‐implant bone resorption values ranged from 0 to 1 mm at the end of the observation period (range: 3–19 months). Implant survival and success rates were therefore 100%. No prosthetic complications occurred and all implants are still in function; therefore the prosthesis success rate was 100%. Conclusion Narrow diameter implants fabricated with the new titanium–zirconium alloy were demonstrated to be reliable in supporting both fixed and removable prosthetic rehabilitations in horizontally deficient ridges. Implant survival, peri‐implant bone resorption, and prosthetic complication rates were consistent with those reported in the literature for standard diameter implants placed in non‐deficient edentulous ridges.
