Impact of annual bone loss and different bone quality on dental implant success – A finite element study

In vitro study of proximal cancellous bone loss effect in the dental implant stability

“…To test the effect of bone loss in the proximal region of the cancellous bone around dental implant the bone was removed. The effect of bone loss was 0.2 mm in deep per year has been taken into account (Linetskiy et al 2017). Was considered two situations, bone loss after 5 and 10 years off implantation, which is equivalent to removing 1 mm and 2 mm of bone respectively proximally.…”

“…After machining the bone with a hole, the implant was self-screwed with a controlled torque at 0.9 N.m with a screw drive. The compression load done in an Instrom Machine 10KN at 14 representing the loads on the tooth (two components) in the vertical and horizontal direction (Linetskiy et al 2017) presented in Figure 1c, applied on a sphere of a diameter of 20 mm. The test was carried out at a speed of 1 mm/ minute up to 355 N in compression, maintaining this force for a total of 60 seconds before relaxation.…”

“…Bone loss around the implant is a critical aspect (Demenko et al 2016) and can predict in long term the stability of fixation (Linetskiy et al 2017). Some studies with finite element model has been developed to predict bone loss in proximal region of cancellous bone and the influence on implant stability, with an effect of 50 to 55% in stability, but is dependently of geometries of implant (Linetskiy et al 2017).…”

The Trends of TiZr Alloy Research as a Viable Alternative for Ti and Ti16 Zr Roxolid Dental Implants

“…This inflammatory process is a result of bacterial biofilm accumulation as a function of diseases such as peri-implantitis, which is a chronic pathological microbial process [4] that affects the soft tissue and surrounding bone areas of an implant. Implant loss can be attributed to a number of factors, ranging from the bone quality and general health of the patient [5] to the incompatibility of the implant, in addition to incorrect insertion techniques. Implant rejection in peri-implantitis caused by the materials' properties and their behavior [6] is an important part of oral health problems.…”

“…Based on ratios between cortical and trabecular tissues, as well as vascularization, bones can be classified into four types, with type I being the most dense and least vascularized, and type IV being the lightest but with high vascularization. One finite element study [5] established functional loads and how bone loss affects the longevity of the implants. This study found that implants have a lifetime of more than 10 years in type I bones, and strains were immediately deleterious for implants in type IV bone.…”
