Endosseous implants may be used to stabilise teeth where attached root length has been lost due to some pathologic al process or to stabilize unsupported teeth following periodontitis.In case of doing this technique for periodontically involved teeth,it is recommended only if there has been a complete control of the periodontal bone loss and active periodontal infection.The implant may be a fabricated nickel chrome wire measuring 1.3 mm or 1.5 mm in diameter.It must be of sufficient length to extend in to the original position of the tooth apex and must also penetrate about 5 mm in to the sound bone beneath.At the coronal end sufficient wire will be required both for manipulation and also for construction of a core to carry a crown.Ready made endodontic implants with appropriate bone drills are also available commercially.
1.Firstly the canal must be carefully and completely reamed to the implant diameter.
2.The apical area is then exposed surgically,irrigated and dried with ribbon aguze and the canal is also dried.
3.The cement is then applied to the canal walls.(EPA that is epoxyorthobenzoic acid or Cold cure acrlic can be used for this purpose)
4.The coronal half of the implant is also covered with cement and then the implant is inserted in to the canal and through the apex where it is carefully wiped with a sterile cotton wool before removing the ribbon gauze pack.
5.The post may be tapped firmly in to the overlying bone and any excess cement is carefully removed and washed out of the bone wound.
6.The coronal end is closed by an apicectomy.
