Additional loss of tooth structure occurs during endodontic access, leading to further weakening of the tooth. Most teeth requiring root canal treatment have been structurally compromised by caries and subsequent restorative procedures. Amount of Remaining Coronal Tooth Structure A bitewing radiograph should be used to evaluate the remaining tooth structure, pulp chamber, and bone levels and periapical radiographs should be used to evaluate tooth length and root morphology. A periodontal probe can be used to measure the height of the remaining tooth structure that will provide a ferrule measure pocket depths, which can reveal periodontal status and possible signs of root fracture and map the subgingival root morphology. This process allows clear visualization of the remaining tooth structure and removes bacteria. The first step is to remove any existing caries and restorative materials.

Evaluation of a tooth requires clinical, radiographic, and esthetic evaluation. Criteria for a Restorable ToothĪ tooth must retain sufficient sound tooth structure after root canal therapy to allow predictable restoration. , This chapter will discuss the considerations needed to properly restore endodontically treated teeth. Specific restorative options must be evaluated based on functional demand and remaining tooth structure. Before endodontic therapy, restorability must be determined this involves careful evaluation of the existing tooth structure, including removal of all caries along with any existing restorations, both to reduce the risk of marginal leakage during treatment and to reveal the amount of sound tooth structure. However, for success the teeth need to be restored to their previous form and function. Outline indications for post placement in anterior and posterior teeth.ĭescribe common post systems and the advantages and disadvantages of each.ĭescribe core materials and their placement.ĭescribe techniques for restoring an access opening through an existing restoration.Įndodontic therapy is predictable.

The final artificial tooth can be removable or fixed, depending on preference.After reading this chapter, the student should be able to:ĭescribe the main factors involved in the survival of root-filled teeth. New teethĪbout two weeks following abutment placement when your gums have healed, your dentist will take impressions to make the crown. You and your oral surgeon can discuss which way is best for you. In some procedures, the abutment is attached to the post during the original surgery, eliminating the need for the second procedure. The abutment is the piece of the implant that extends above the gum and that the crown (your real looking artificial tooth) will be attached to. Once ossification is satisfactorily complete, your dental surgeon will reopen your gum and attach the abutment to the implant. It will take time (commonly 2 to 6 months) for that growth to become the solid base you need for the new, artificial tooth or teeth. Your jawbone will grow into the implant, which is called osseointegration.

Your dentist might also recommend eating only soft foods for about a week. Your dentist may also prescribe antibiotics and pain medication. Your gum will be closed over the post.Īfter the surgery, you’ll be given instructions for proper aftercare and oral hygiene during the recovery period. They’ll then drill holes in the bone and implant the endosteal post deep into the bone. Implant placementĪfter numbing the area, your initial surgery will include your oral surgeon cutting your gum to expose your jawbone. In these meetings you’ll also review the entire procedure, including payment and time commitments. That diagnosis and recommended treatment must be confirmed by a dental surgeon. The first step, of course, is for your dentist to determine that you’re a viable candidate.
