Abstract

Background: Poor bone volume in the alveolar ridge resulting from long edentulism can be observed in the first year of tooth loss as decreased ridge width forcing an improper placement of the dental Implants without additional surgical procedures to reconstruct the original anatomy of the alveolar crest. Osseodensification is a suitable biomechanical technique to overcome this possible obstacle, which uses a counterclockwise, non-cutting densifying bur utilizing a non-subtractive densifying method to increase the peri-implant bone density.
Objectives: To compare and measure the changes in the peri-implant bone density with osseodensification (OD) and rotary expanders’ techniques with simultaneous implant placement.
Materials and methods: Fourteen patients requiring implant placement in the anterior maxillary region till the premolar region were randomly selected and divided into two groups (seven patients per group), the control group was operated on with the rotary expanders’ technique, and the test group was operated on with the osseodensification (OD) technique. The Radiographical evaluation was performed preoperative and postoperative (immediate, 6 months) to assess the changes of the peri-implant bone density.
Results: Statistical analysis of the radiographical evaluation proved that the densifying burs enhanced the peri-implant bone density more than the rotary expanders, where the mean peri-implant bone density of densifying burs values were ( 758.8 preoperative, 1013.1 immediate postoperative, and 1170.0 after 6months ).
Conclusion: Within the limitations of this study, results allow the conclusion: both rotary expanders and osseodensification burs improve the peri-implant bone density, but without a significant difference.
