The most predictable way to assure optimal healing and readiness for completing a successful implant procedure is to wait six to nine months after extraction. Bone augmentation can be initiated one to two months after the extraction.
After implant placement the upper jaw requires six months for osseointegration. The final surgical step involves exposing the implants and the placement of healing abutments for two weeks.
The next phase involves the placement of a final abutment and a provisional(temporary) restoration. Ideally this would remain in place for several months to condition the bone. When the implant osseointegrates woven bone forms. This type of bone is made up of randomly directed cells. When the bone is under load it forms lammelar bone. This type of bone is in distinct layers and is able to handle the forces of chewing. Depending on the studies this protocol has a 98-99% success rate.
Candidate for Immediate Load (One Day) Implants?
In some situations, if there is sufficient height, width and density of existing jaw bone material there are other options.
The tooth can be extracted very carefully, the implant immediately placed, a final abutment immediately placed along with a provisional crown. The patient walks out of the office with teeth!
Since the implant is loaded immediately, lammelar bone forms during osseointegration. The final crown can be placed in about six months.
The success rate for immediate placement drops slightly to 96%, depending on the skill and experience level of the doctor. In the event that there is a failure often the next size larger implant can be placed. Otherwise the traditional technique can be used.
In order to provide the immediate technique, the dentist must be proficient in both the surgical and prosthetic phases, have a large inventory of implants and abutments. It is imperative that the teeth are taken out with minimal trauma to the bone. In most cases patients do not require analgesics postoperatively.
