“…Similar results were obtained in another study [446]. Periodontal ligaments around extracted sockets were found to have an ability to regenerate bone on HA-coated tooth-shaped implants [341]. Positive results were also observed in another study, in which bone formation around BCP (HA + β-TCP) particles in periodontal defects of dogs were found to be more discernible if compared to healing in control [486].…”

The molecular precursor method is an easy and simple method for coating thin carbonate-containing apatite (CA) films onto titanium surfaces. A molecular precursor solution containing ethanol, calcium-EDTA complex, and phosphate salt was dropped onto a titanium surface and then heated at 600°C for 2 h. An adherent thin CA coating was achieved. Animal implantation experiments showed that CA-coated implants had significantly higher bone-to-implant values than non-coated implants (p<0.05). The molecular precursor method was also used to coat three-dimensional titanium webs (TWs). Thin CA films could be coated inside the center area, as well as the surface of the TW, with excellent bone formation inside the CA-coated TW. Furthermore, the molecular precursor method was used to coat partially stabilized zirconia with CA. Better bone response was observed for CA-coated zirconia. From this, it is concluded that the molecular precursor method is useful for producing thin CA coatings on implant materials.

“…Studies showed that implant made of titanium, poly(methylmethacrylate) and dacron implanted into alveolus of rabbit could give rise to attachment apparatus whose mechanical behaviour was comparable to periodontal ligament [65]. Authors found that periodontal ligament (PDL) like tissues could be induced on HA coated titanium dental implants when subjected to occlusal load in rats [66]. Reports suggests that placing custom-made, titanium implant in hollowed roots with narrow slits, give rise to growth of periodontium like tissue onto it [67].…”

This review paper investigates the possible transformation of endosseous dental implant, primarily from the current osseointegrated to the future ligament anchored implant within which a new class of implants with enhanced feature of "neuro-ligament integration" may appear. Endosseous dental implants used presently to replace missing teeth get fused with bone but they do not have any periodontal ligament interface between the alveolar socket and the surface of the implant, which natural teeth do. Hence, they lack any proprioceptive sensation, which is important for discrimination, directional and masticatory sensation. Attempts have been made to regenerate periodontium around the implant in 90s, which was not completely successful. Thereafter, there has been limited research. However, recent advances in tissue engineering and biomaterials gave renewed hope of establishing sensory dental implants. In this review, various methods of regeneration of periodontium onto the surface of titanium implants have been discussed along with the possible types of neurological assessment and neuroimaging that could be carried out for validation of its afferent feedback. The review starts by giving background information of major stages and terminologies in the field of oral implants, its response to host tissue in bone, various surface modification of dental implants, stem cells that are used for periodontal regeneration, different approaches for regeneration of periodontium, concept of proprioception in periodontium, osseoperception of dental implants and concludes with neurophysiology of oro-dentofacial region in brain including its detection and measurements methods.
