Purpose Evaluation of the available research on PEEK materials to find that whether PEEK material has favorable properties and can enhance osseointegration, so that they can be utilize as implants material. Materials and Methods An electronic and structured systematic search was undertaken in May 2018, without any restrictions of time in the Medline/Pubmed, Sci‐hub, Ebscohost, Cochrane, and Web of Science databases. To identify other related references further hand search was done. Articles related to PEEK and their applications in implants were only included. Articles not available in abstract form and article other than English language were excluded. Results Initially, the search resulted in 153 papers. Independent screenings of the abstracts were done by the reviewers to identify the articles related to the question in focus. Sixty‐two studies were selected out of which 10 were further excluded due to not in English language. Two additional papers were obtained after hand searching, and finally 54 articles were included in the review. Conclusions Surface modification of PEEK seems to enhance the cell adhesion, proliferation, biocompability, and osteogenic properties of PEEK implant materials. PEEK had also influence the biofilm structure and reduces the chances of periimplant inflammations. Further research and more number of controlled clinical trials on PEEK implant is required in near future so that it can replace titanium in future.

“…The loads applied during the experiment were below maximum masticatory forces recorded for humans, as maximum forces are not achieved during grinding. A magnitude of load 100 N was selected considering these reasons and simulating other in-vitro studies (28,30).…”

“…The elastic modulus of BioHPP lies in the range of 4000 MPa, which very strongly resembles the elasticity of human bone, so that the chewing forces are, therefore cushioned (32). It has lower modulus of elasticity than zirconia (28). Hence, it reduces the stresses generated on the bone, absorbs more energy from the applied load, and transfers less energy to the bone.…”

INTRODUCTION: The use of short implants has been introduced as an alternative treatment for posterior regions, however, it leads to serious prosthetic complications. Using CAD/CAM, materials like zirconia and Bio-HPP can be used to fabricate implant supported restorations. OBJECTIVES: This study aimed to evaluate and compare the strains developed around short and standard implant length using two different crown materials. MATERIALS AND METHODS: Polyurethane blocks (n=20) were used as alternative materials for human cancellous bone. Blocks were divided into two groups, group A received ten standard length implants 12 mm, and group B received ten short implants 7 mm. Each group was equally subdivided into two subgroups, according to crown material (BioHPP and zirconia). Universal testing machine was used to apply a load of 100 N axially and obliquely at 45° on the restorations. Microstrains were measured using strain meter. RESULTS: The difference in microstrain values between BioHPP and zirconia was statistically insignificant for both group A and group B. Comparing between group A and group B having the same restorative materials, it was found that, the difference was statistically significant for zirconia in axial loading only. A significant difference was observed between oblique and axial loads in standard implant length for both BioHPP and zirconia restorations, and for zirconia in short implants as well (p value=0.043), while the difference was insignificant for BioHPP in short implants. CONCLUSIONS: Short implants are comparable treatment modality to standard implant lengths for single tooth restoration. Oblique forces produce more stresses than vertical forces. According to the average of loads, there is no significant difference between BioHPP and zirconia for both short and standard implant length. However, it is advisable not to use zirconia restorations with short implants.

“…The AnyOne ® External and AnyOne ® OneStage are able to better distribute the load due to their unnotched shape. Several studies [34][35][36] have focused on the influence of the implant-abutment connection on the stress distribution in the peri-implant bone. In the present study, as observed by different authors [17,[37][38][39], the most stressed bone tissue is the cortical one.…”

Prosthetic and Mechanical Parameters of the Facial Bone under the Load of Different Dental Implant Shapes: A Parametric Study

et al. 2019

View full text Add to dashboard Cite

In recent years the science of dental materials and implantology have taken many steps forward. In particular, it has tended to optimize the implant design, the implant surface, or the connection between implant and abutment. All these features have been improved or modified to obtain a better response from the body, better biomechanics, increased bone implant contact surface, and better immunological response. The purpose of this article, carried out by a multidisciplinary team, is to evaluate and understand, through the use also of bioengineering tests, the biomechanical aspects, and those induced on the patient's tissues, by dental implants. A comparative analysis on different dental implants of the same manufacturer was carried out to evaluate biomechanical and molecular features. Von Mises analysis has given results regarding the biomechanical behavior of these implants and above all the repercussions on the patient's tissues. Knowing and understanding the biomechanical characteristics with studies of this type could help improve their characteristics in order to have more predictable oral rehabilitations.
