Methods: Sixty two delay loading angulated implants|(in two groups of 5-15’ and 15-25’) were studied .All implants were evaluated during an average of 37 months after insertion. Marginal bone level was measured through radiographic examination and periodontal probing
Results: The average bone loss around the implants with the angulation of 5-15’ was documented 1.04mm and it was 1.06mm in the other group. NO significant statistical difference was seen in the bone loss of these two groups. Evaluation of pocket depth in the buccal site of the implants showed mean of pocket depth in group1 was 3.4 mm and in group 2 was 3.6 mm .Statistical analyze showed no significant difference between two groups.
Conclusions: The results showed that increasing the angulation of implants in the anterior region of the jaws has no effect on the success rate of implants and bone loss around them.
