To compare and Evaluate Marginal Bone Loss Around Short and Long Implants Placed in Posterior Maxilla via Conventional Drills and Osteotomes.

Abstract

PURPOSE-To calculate the marginal bone loss occuring around short and long implants placed using bone condensing osteotomes as well as using conventional drilling and to understand the viability of osteotome technique and short implants. MATERIALS AND METHODS- An in‑vivo study was undertaken to evaluate the crestal bone loss on mesial and distal aspect of short and long implants placed via osteotomes and conventional drills (group A,B,C,D 5 implants per group) using standardized intra‑oral periapical radiographs at baseline,3 months and 3 months post loading Statistical Analysis Used: Student’s unpaired t‑test. RESULTS- Long implant via drills and osteotomes were group A and B and their results were statistically significant different (p < 0.004), short implant via drills and osteotomes were group C and D where better bone level was observed for short implant via osteotomes, when compared long implant via osteotome(group B) and short implant via osteotome The results show that bone level measurement at 3 months post loading were higher at mesial (0.52mm) and distal (1.06mm) positions for long implants compared to short implants placed via osteotome. The results were statistically significant (p<0.05).CONCLUSION-Considering the limitations of implant placement in the posterior maxilla, osteotome and short implants are a non-invasive and predictable procedure for allowing implant placement and bypassing the invasive surgical, bone augmentation and graft procedures.
