Objectives: To evaluate and to compare the effect of the conical neck design on marginal bone loss around the fixtures, when both implants were provided with micro‐threads to the top of the fixture. Materials and methods: Two types of implant, one with a straight shape (S) and the other with a conical neck design (C) provided with a retentive element to the top of the fixture, were placed adjacent to each other in the partially edentulous areas of 12 patients. Bone loss around each implant was analyzed after 1 year of functional loading. The bone losses after loading were compared using Wilcoxon's signed‐rank test. Results: The mean marginal bone losses (S, 0.05±0.09 mm; C, 0.07±0.14 mm) were not statistically significant between the two groups ( P =0.578). Conclusions: There was no significant difference between conical and straight neck implants in terms of marginal bone loss after 1 year of loading. To cite this article:
