Influence of time on primary stability of dental implants placed with osteotomes due to the elastic properties of peri-implant bone

Abstract

Background/purposeThe use of osteotomes as a technique for densification and expansion of the residual ridge is one of the most widely used procedures to achieve adequate peri-implant bone quantity and density. The aim of this study was to evaluate the influence of time and the elastic deformation of peri-implant bone in the primary stability of implants placed using osteotomes.Materials and methodsIn each of 10 fresh fragments of cow rib, two implants were placed using osteotomes. The insertion torque and initial implant stability quotient (ISQ) values were measured. In the control implants, the immediate removal torque was measured, while in the test implants, after 15 min of placement, ISQ values were measured again, and the removal torque was measured.ResultsThere were significant differences between the ISQ values and between the insertion torque and removal torque at 15 min. The ISQ values (perpendicular/parallel) increased between the initial moment (64.4 ± 9/70.3 ± 5.9) and 15 min (66/71.4 ± 6.4). The removal torque at 15 min (12.4 ± 5.8) was lower than the insertion torque (15.9 ± 5.9). Compression of the trabeculae in contact with the implant placed using osteotomes was observed, as well as a greater number of trabecular fractures in the implants placed using conventional drilling.ConclusionThere is an increase in ISQ values of dental implants placed using osteotomes after 15 min of placement.

Evaluation of the primary stability in dental implants placed in low density bone with a new drilling technique, Osseodensification: an in vitro study

“…The bone expansion technique using expansion osteotomes to create the bone bed was an alternative attempted to improve primary implant stability ( 4 , 6 , 14 - 16 ). Osteotomes enable condensing of bone trabeculae, which improves peri-implant bone density rather than removing bone by drilling, with consequently improved primary stability ( 18 ).…”

Determinants of Temperature Development during Dental Implant Surgery

“…The observed slower insertion process of the MT implant is due to a comparably small thread pitch, which on the one hand requires more surgical time but allows the bone to respond to inevitable deformation during implant insertion [45]. Furthermore, the slower insertion process facilitates precise positioning of the implant-abutment interface in the vertical dimension.…”

Comparative Evaluation of Marginal Bone Levels, ISQ Trends, and Implant Survival Rates Between Conventional Drilling and Osteotome Technique Using Implants of Varied Lengths: A Split-Mouth Randomized Controlled Clinical Trial

“…11 As compared to conventional drilling protocols, the Summers technique was considered to be effective in situations of low bone density as bone drilling leads to development of a necrotic border zone around the surgically created implant site. 12,13 However contradictory results in terms of bone loss and primary stability have been reported in literature when the osteotome and conventional drilling techniques were compared. 14,15 A randomized control trial reported that the osteotome technique leads to higher primary implant stability in the initial three months.…”
