Abstract: Preservation of interdental papilla and the need for esthetics are being progressively considered an essential criteria since crestal bone loss before loading may compromise implant success. Extensive and conserved flap designs frequently used in implant surgery.  Salivary Alkaline phosphatase could be used to detect possible turnover process in the bone. This study evaluated crestal bone loss interproximally and to assess Alkaline phosphatase level occurring after implantation of single-tooth using two different flap designs. A total of 24 patients aged in range between 20-40 years underwent implant installation.  Participants were divided in 2 groups: group A (12 patients) treated with extensive type, and group B (12 patients) with conserved one. Saliva was sampled from each patient five times (before, 2, 4, 12 and 24 weeks after surgery). An intraoral paralleling radiograph was taken as a baseline to evaluate the relation between the crestal bone and the dental fixture, one day and 24 weeks after surgery. The maximum amount of crestal bone loss on both mesial and distal sides for extensive was 0.6 mm while for conserved was 0.3 mm. The highest mean of Alkaline phosphatase in conserved type was seen in 2 weeks following surgery (7.04), while for extensive one was 6.95. The study results indicated that loss in the crestal bone interproximally was of practical importance and statistically significant less subsequent to the use of a conserved flap design when compared with the extensive type, also Alkaline phosphatase could be useful as a potential marker for bone turnover.
