Dental implants are used to replace single or multiple missing anterior and posterior teeth in both lower and upper jaw. There are two ways of placing implants, the immediate implant placement and the delayed implant placement. Both methods have different requirements. Not everybody will be suitable for an immediate dental replacement procedure due to, for example, a need to carry out a bone grafting procedure.
It is possible to place a dental implant immediately after the removal of the tooth. In cases of fractures, root resorption or due to a failed root canal the tooth can be removed and immediately replaced with a dental implant.
In order for the immediate dental placement to be successful aesthetically, the tooth needs to be removed without compromising the bone and gum tissues surrounding the tooth. To achieve such a result, the dental surgeon needs to perform very precise surgery. Any errors which might cause injuries to the bone could threaten the final result and leave the patient with an unaesthetically pleasing appearance. Such an outcome would be especially unacceptable in replacing the anterior teeth where it could be clearly visible when talking or smiling.
For the immediate dental placement to be successful the implant must be stable. Sometimes, to achieve stability the dental implant must be attached to the bone. In order to preserve the natural outline of the tooth, the dentist often fills the gaps around the dental implant with bone grafting material. Such precise stabilization and positioning is essential in order to give the artificial tooth the look of a natural tooth. Additionally a temporary crown should be placed to protect the implant from direct biting forces to ensure the success of the treatment.
There are cases where immediate implant placement is impossible or at least advised against. Sometimes after the tooth is lost or removed the bone is insufficient for the dental implant placement to be performed immediately, so this is delayed until the site of treatment is properly prepared.
When the bone is insufficient bone grafting is performed. Thanks to this, the dental implant is more stable and the treatment has higher chances of success. Bone grafting makes even the worst, seemingly hopeless cases of missing teeth eligible for dental implant treatment. When the bone grafting does its job the dental implant can be placed.
After this, the dentist can attach a temporary crown to the dental implant so it is protected from the biting forces, ensuring it is safe from damage or any movement which could cause the failure of the bone and implant fusion. This process of fusion is essential to the final success of dental implant treatment. A well-stabilized and protected implant will fuse with the bone after a couple of weeks to a month or a bit longer. After the implant and bone have sufficient time to fuse, the dental surgeon will be able to place the final crown on the dental implant.
