“…11,12 Many materials have been advocated for use as endodontic dental implants. Vitallium was originally used but its biocompatibility was questioned 13 and the two materials in use because of their superior biocompatibility are titanium and aluminium oxide, which is a single crystal sapphire. 14 Bioceramic coatings have been used to modify the surface of implants and in some cases to create an entirely new surface, which are quite different from the uncoated device.…”

Endodontic dental implants have been used for many years. Many materials have been advocated for use as endodontic implants but a few of them have shown biocompatibility and have been acceptable. The aim of this study was to design and produce a novel biomaterial by producing a new surface coating on metallic substrate in order to achieve two goals, namely, an improvement in the corrosion behaviour of metallic endodontic dental implant and the bone osteointegration simultaneously. Stainless steel (SS) 316L was used as the metallic substrate and a novel double layer hydroxyapatite/niobium (HA/Nb) composite coating was prepared on it. X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques were utilised to characterise the coating. Electrochemical tests were performed in physiological solutions in order to determine the corrosion behaviour of the coated and uncoated specimens. Two types of endodontic implants were used, including SS with and without novel HA/Nb coating, which were prepared and subsequently implanted in the mandibular canine of 22 cats after completion of root canal treatment and osseous preparation. After a healing period of 4 months, osteointegration evaluation and histopathological interpretation were carried out using SEM and optical microscopy. In vitro tests indicated that the novel HA/Nb composite coating could improve the corrosion resistance and therefore the biocompatibility of SS endodontic dental implant. The clinical evaluation results showed that the average bone osteointegration of coated implants was more than for uncoated implants. The histopathological results and bone tissue response to the coated endodontic dental implants were acceptable. It can be concluded that HA/Nb composite coated SS could be used as an endodontic dental implant material.

“…Although endodontic endosseous implants are largely historic, their biomechanics are known to be valuable in improving the crown–root ratio and stability of seemingly hopeless teeth affected both by trauma and by periodontal disease . A variety of materials have been used to fabricate endodontic implants including titanium and chrome cobalt. While endodontic implants are generally well tolerated by surrounding tissues , their degree of apical seal has been unpredictable .…”

Root fractures in the middle and apical thirds of the root are treated by repositioning and for approximately 6 weeks of immobilization while those in the cervical third are immobilized for 3 months. Even though the results are good, some root-fractured teeth are lost and replaced by dental implants or fixed partial dentures. One historic but effective treatment option for those root fractures with unfavorable crown to root ratios is an endodontic implant in middle and apical third root fractures. This method offers immediate stable fixation of a crown and its coronal root segment to the underlying alveolar bone. This report documents the long-term survival of a tooth treated with an endodontic implant. A 25-year-old male patient presented following a bicycle accident with a dislocated unfavorable root fracture in the middle third. The crown with the coronal root segment was secured to the bone using a commercially available endodontic implant. The apical part of the root was removed. Although the clinical and radiological follow-up results of the endodontic implant demonstrated a good clinical function and little bone loss, the implant ultimately had to be removed after 22 years of service due to pain and increasing mobility.

A cobalt based alloy, MP35N, with excellent mechanical properties has been recently introduced as a material for surgical orthopedic implants. A study was made of local and systemic host response to this material in two different mammal species. The implantation time ranged from one to 12 months. The result of this study indicated: MP35N produces a degree of local tissue response comparable to that of 316L stainless steel. No systemic side effects were observed during the implantation times included in this study.
