| Background: Implant geometry has a major impact on insertion torque values and primary stability, and bone engagement during implant insertion differs according to implant morphology. Objective: This study was aimed to compare the implant survival and success as outcome of 2 types of implant morphology either the tapered or cylinder form in delayed immediate placement of dental implant. Materials and methods: A total of 20 implants (10 for tapered and 10 for cylinder implants) were inserted after tooth extraction i.e. delayed immediate implant placement. The primary stability of each implant was measured by using insertion torque value. Then, implant examined clinically and radiographically for success criteria after placement. Results: The insertion torque measurement was showed 38.50 ± 4.74Ncm as a mean value for the tapered implant and 26.0 ± 5.16 Ncm for cylinder implant while the insertion time for tapered was 0.71 ± 0.07 second/mm and for cylinder was 0.95 ± 0.14 second/mm. Conclusion: Tapered implants showed better primary stability than straight-walled implants and had a higher success rate. A higher insertion torque can lead to the destruction of peri-implant bone, compromising osseointegration and failure of dental implant. | ||||
