“…Low PS is sometimes unavoidable in clinics because of anatomical, pathological, and iatrogenic issues. It tends to occur in patients with systematic diseases leading to bone metabolism problems, immediate implantation situations in the oversized implant bed caused by an improper drilling protocol, prolonged inflammation in alveolar bone and fresh extraction socket, or delayed implantation in challenging bone conditions, such as posterior maxillary site [ 11 , 12 ]. To tackle low PS, the bone substitute is routinely recommended in the circumstances described above to create a wedging effect of the implant within the peri-implant defect [ 13 , 14 ].…”

Objectives To evaluate the histological parameters and bone mechanical properties around implants with low primary stability (PS) in grafted bone substitutes within an oversized osteotomy. Materials and methods An oversized osteotomy penetrating the double cortical bone layers was made on both femora of 24 New Zealand white rabbits. Bilaterally in the femur of all animals, 48 implants were installed, subdivided into four groups, corresponding to four prepared tissue-engineering bone complexes (TEBCs), which were placed between the implant surface and native bone wall: A: tricalcium phosphate β (TCP-β); B: autologous adipose derived-stem cells with TCP-β (ASCs/TCP-β); C: ASCs transfected with the enhanced-GFP gene with TCP-β (EGFP-ASCs/TCP-β); D: ASCs transfected with the BMP-2 gene with TCP-β (BMP2-ASCs/TCP-β). Trichrome fluorescent labeling was conducted. Animals were sacrificed after eight weeks. The trichromatic fluorescent labeling (%TFL), area of new bone (%NB), residual material (%RM), bone-implant contact (%BIC), and the removal torque force (RTF, N/cm) were assessed. Results ASCs were successfully isolated from adipose tissue, and the primary ASCs were induced into osteogenic, chondrogenic, and adipogenic differentiation. The BMP-2 overexpression of ASCs sustained for ten days and greatly enhanced the expression of osteopontin (OPN). At eight weeks post-implantation, increased %NB and RTF were found in all groups. The most significant value of %TFL, %BIC and lowest %RM was detected in group D. Conclusion The low PS implants osseointegrate with considerable new bone in grafted TEBCs within an oversized osteotomy. Applying BMP-2 overexpressing ASCs-based TEBC promoted earlier osseointegration and more solid bone mechanical properties on low PS implants. Bone graft offers a wedging effect for the implant with low PS at placement and promotes osteogenesis on their surface in the healing period.

“…23 Haseeb et al compared the implant stability and insertion torque of two different macro geometry in different bone densities and concluded that lower insertion torques of new implant types help in reducing failure. 24 Gandhi et al evaluated how two different implant designs responded to conventional osteotomy drilling and found that tapered pro implant design offered a better primary stability when osseodensification was used. 25 Insertion torque is defined as the amount of torque required to place the implant into the prepared osteotomy site.…”

Purpose Compression necrosis refers to bone tissue damage that can occur when excessive pressure or force is applied to surrounding bone during implant placement. This pressure can compromise blood supply to the bone, leading to necrosis. Compression necrosis is a concern, because it can affect the stability and long-term success of dental implant. Patients and Methods This case report highlights a case of early bone loss and implant failure possibly due to compression necrosis. Clinical data, photographs, radiographs, blood examination report and histology were presented to document the early failure of an implant placed in the mandibular left posterior region of a 33-year-old female patient. Results Radiograph taken six weeks after implant placement showed severe angular defect. Therefore, the implant was surgically removed. Histological examination of the area showed bony trabeculae with an absence of osteoblastic riming, suggestive of necrotic bone. Conclusion Using excessive torque values when placing implants in dense bones can increase the risk of implant failure due to bone over compression. Dental professionals must follow the manufacturer’s instructions and employ quality surgical techniques during implant placement into dense cortical bone to minimise risks.

Materials and Methods An oversized osteotomy penetrating the double cortical bone layers was made on both femora of 24 New Zealand white rabbits. Bilaterally in the femur of all animals, 48 implants were installed, subdivided into four groups, corresponding to four prepared tissue-engineered bone grafts (TEBGs), which were placed between the implant surface and native bone wall: A: tricalcium phosphate β (TCP-β); B: autologous adipose derived-stem cells with TCP-β (ASCs/TCP-β); C: ASCs transfected with the enhanced-GFP gene with TCP-β (EGFP-ASCs/TCP-β); D: ASCs transfected with the BMP-2 gene with TCP-β (BMP2-ASCs/TCP-β). Trichrome fluorescent labeling was conducted. Animals were sacrificed after eight weeks.

Results The BMP-2 overexpression of ASCs sustained for ten days and greatly enhanced osteogenic differentiation. At eight weeks post-implantation, increased %NB and RTF were found in all groups. The most significant value of %TFL, %BIC and lowest %RM was detected in group D. Conclusion The low PS implants osseointegrate with considerable new bone in TEBGs peri-stuffed site. The addition of ASCs and BMP-2 further stimulated the %BIC. Bone graft offers wedging effect for the implant with low PS at placement and promotes osteogenesis on their surface in the healing period.
