This study evaluates the efficacy of reamer mediated crestal sinus floor elevation with noninvasive sinus crestal approach technique in periodontally compromised patients with and without the use of porous titanium granules (PTG) as augmentation material. Fourteen patients aged from 26 to 56 years. Patients were divided into two groups (seven patients each), Group I: the implant was placed in combination with sinus crestal approach technique with the use of collagen membrane and metallic porous titanium granules (Tigran granules). Group II: implant placed with the same technique as group I without any regenerative material. Patients were followed up clinically and radio graphically for six months. In group I and group II respectively the mean height of the residual sub antral bone was 7.40 ± 0.57mm and 7.71 ± 0.49mm, whereas mean elevation of the sinus floor were 3.03 ± 0.51 and 3.14 ± 0.56 mm. Marginal bone loss was 1.12 ± 0.5 mm and 0.55 ± 0.41mm. Newly formed bone was 2.89 ± 0.02 mm and 1.50±0.14 mm. Density of newly formed bone was 45.25 ± 0.72% and 24.50 ± 0.72%. None of the patients experienced any discomfort during the procedure. The Sinus Crestal Approach kit provides an alternative, risk free method for sinus lift when compared to traditional methods. Porous Titanium Granules are a novel non-resourbable and genuinely osteoconductive bone graft substitute. Highly significant difference was founded in the amount of newly formed bone and its density in group I than group II (P ≤ 0.05).
