Performance of the counter-torque technique in the explantation of nonmobile dental implants

Abstract

Background: The application of the counter-torque technique has been proposed as a conservative and atraumatic alternative for the explantation of nonmobile dental implants. The objective of this report is to assess the performance of this technique in a large number of patients. Results: Three hundred and fifty-five patients were treated for the explantation of 749 nonmobile dental implants. The explantations were performed by the application of counter-torque to break the bone-implant interface. Successful implant explantation was achieved in 98.4% of the implants. The frequency of complications was 1.3%, most commonly related to the appearance of fissure lines at the implant neck. Conclusions: The counter-torque technique has a high success rate but is not exempt from complications, although at a very low rate.

Clinical Application of Bone Marrow Mesenchymal Stem/Stromal Cells to Repair Skeletal Tissue

“…Importantly, efforts are being made to determine how BMSC are subsequently integrated to form the correct cell configuration and able to differentiate, repair and recapitulate the functional skeletal tissue and how mechanical loading is exerted upon the MSC engineered bone [ 42 ]. Another consideration is to improve/restore or modulate the diseased or disrupted microenvironment prior to the commencement of the regenerative therapy, to ensure greater efficacy in skeletal repair [ 43 ]. Furthermore, a permissive vascular environment is imperative for bone formation, where vascular supply assists in bone regeneration by mitigating hypoxic conditions and necrosis within the scaffold, in addition to the strong coupling between angiogenesis and osteogenesis.…”

“…The methods developed to recruit endogenous BMSC and deliver exogenous BMSC systemically or locally ( Figure 1 ) include cell-free strategies, magnetic cell labeling and tissue specific targeting, aptamer-nanoparticles, small bioactive molecules, injectable agents, the use of platelet-rich plasma (PRP) or bone marrow aspirates, BMSC secreted exosomes, and bio-engineered scaffold approaches, including three dimensional (3D) bioprinting (bioinks) [ 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 ].…”

Oral Lichen Planus and Dental Implants: Protocol and Systematic Review

“…Given the foregoing [ 30 ], our workgroup would like to propose a protocol for OLP treatment and monitoring when rehabilitated with dental implants ( Figure 3 ).…”

Antibiotic-loaded amphora-shaped pores on a titanium implant surface enhance osteointegration and prevent infections

“…The position of the K-wire was checked by x-ray immediately after surgery and during the follow-up. An osteointegration score modified from Das et al [ 11 ] was used to evaluate the macroscopic and radiographic changes in soft tissue swelling, implant movement, surface irregularities, hyperplastic growth/periosteal reactions, and peri-implant bone radiolucency. Each parameter was scored from 0 (no changes) to 3 (severe changes).…”

“…PSM inhibits bacterial adherence due to a modified surface chemistry or surface topography [ 9 ]. In general, hydrophilic surface conditions [ 10 ], structured surface topography [ 11 ] and porous structures [ 12 ] can enhance the osteointegration of the implant. Laser surface treatments for improved osteointegration are the state of the art, but these differ in terms of the details of the respective surface topographies.…”
