Titanium, usually commercially pure but sometimes a 90% alloy, is used as the anchor for dental implants as it is biocompatible and can integrate into bone. Precious metallic alloys. gold (high purity: 99.7%) gold alloys (with high gold content) gold-platina alloy; silver-palladium alloy; Base metallic alloys. cobalt-chrome alloy; nickel-chrome ...
Root analogue ceramic dental implant in comparison with titanium screw type implant. As technology has improved, so has implant success rate. Conventional titanium dental implants typically have success rates of 90–95% for 10-year follow-up periods, but this is based on questionable definitions of success. [5]
Therefore, the pulp has to be removed. If the root canals of the abutment teeth are obliterated, endodontic treatment is not required. Teeth with non-negotiable root canals should not be selected as abutments. Implant-supported. Edentulous patients with sufficient amount of bony ridge on their jaws can opt for implant supported overdenture. [4]
Contact should be avoided with the root of the teeth and attempts to cleaning through the use of either soaps, chemicals or toothpaste must not occur. [20] Too much damage occur to the periodontal membrane or fibrolasts, tooth reimplantation may become unviable due to the complications that it presents due to ankylosis and root resorption.
An unusual root canal shape, complex branching (especially the existence of horizontal branches), and multiple root canals are considered as the main causes of root canal treatment failures. (e.g. If a secondary root canal goes unnoticed by the dentist and is not cleaned and sealed, it will remain infected, causing the root canal therapy to fail).
A root end surgery, also known as apicoectomy (apico-+ -ectomy), apicectomy (apic-+ -ectomy), retrograde root canal treatment (c.f. orthograde root canal treatment) or root-end filling, is an endodontic surgical procedure whereby a tooth's root tip is removed and a root end cavity is prepared and filled with a biocompatible material.
Onlays are indicated when there is a need to protect weakened tooth structure without additional removal of tooth tissue unlike a crown, e.g. restoring teeth after root canal treatment to give cuspal coverage. It can also be used if there is minimal contour of remaining coronal tooth tissue with little retention. [7]
An x-ray of a root canal operation. Before endodontic therapy is carried out, a correct diagnosis of the dental pulp and the surrounding periapical tissues is required. This allows the endodontist to choose the most appropriate treatment option, allowing preservation and longevity of the tooth and surrounding tissues.
