Factors Affecting the Success of Dental Implants

Evaluation of oral microbial corrosion on the surface degradation of dental implant materials

“…Dental implants are some of the most successful implantable devices with ≈3 million being used in the United States alone and ≥500,000 new implants being placed annually . The majority of dental implants today are manufactured from commercially pure titanium (Ti) with survival rates of 90.9% to 97.7% being reported after 15 years post‐implantation . The high success rates of Ti dental implants stem from the formation of an oxide layer (primarily TiO 2 ) that shields the underlying metal from the oral cavity while providing a suitable substrate for osseointegration .…”

A histomorphometric study on treated and untreated ceramic filled PEEK implants versus titanium implants: Preclinical in vivo study

“…Specimens were either untreated or were surface treated with 50 µ, 110 µ, or 250 µ aluminum oxide particles. The authors found that the CFRP and CFP specimens treated with 110µ exhibit low contact angles and moderately rough surface (1-1.5 µm) and were thus suggested as potential substrates for fabrication of dental implants (Elawadly et al, 2017;Elias, 2011). Based on the findings of previously described study, CFP was selected because of its favorable surface properties and its white color, which can be considered advantageous in jaw regions of high esthetic demand.…”

“…The titanium implant has a moderately rough implant surface with an Ra value of 1.59 μm (Elias, 2011). Nine implants were randomly selected from the eighteen milled PEEK implants and were sandblasted by 110 µ aluminum oxide particles under pressure of 5 bars for 10 s at a fixed distance of 50 mm resulting in Ra value of 1.55 μm (SCFP).…”

“…Various techniques have been employed to improve the bioactivity of the material, among which are surface coating and surface treatment or a combination of both techniques (Ma & Tang, 2014). Such treatments led to modification of the roughness average values (Ra value) and wettability of material, which were said to influence BIC (Elias, 2011).…”

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

“…The lack of a tooth is a recurring problem due to functional and aesthetic changes and there are more and more solutions, mainly dental implants as a solution. Several factors affect the integrity of the dental implant (Nelson 2011), but the main cause of implant failure is peri-implantitis, which generates infection and bone loss; another critical aspect is the lack of bone integration after implantation (Kullar and Miller 2019).…”
