An immediate dental implant is an implant, which is placed within the tooth socket as soon as the tooth is extracted.
There are a lot of advantages of this technique.
1- In the conventional two stage technique, after the extraction of the tooth , one has to wait for six months for fresh bone to form and then only one can proceed with the implant surgery. In the immediate implant technique, the six month waiting period is eliminated, as the implant is given on the same day of the extraction with a temporary tooth on it.
2- The second surgery is also eliminated in an immediate implant case. The healing process is a natural one, where the body builds fresh bone around the implant.
3- In many cases the procedure is flapless, which means the surgery is conservative .
4- The size of the implant used in this procedure, is equal to or slightly more than the size of the natural root , so more conservation of bone occurs here and the contour / form of the ridge i.e. jaw bone is maintained.
5- This procedure provides a more esthetic look of the final crown, as a more natural tooth angle and emergence profile can be maintained.
6- Last but not the lease the patient gets instant gratification.
However certain factors have to be kept in mind while selecting a case for an immediate dental implant.
To ensure best results a systematic approach should be adopted by the dentist .
Step 1- is the comprehensive data collection of the case i.e. photographs, study models, OPG, X-Ray and CT scan.
Step 2- is a thorough consultation with the patient. This includes getting the patient history of any medical problems like diabetes, blood pressure, bleeding disorders, radiation history etc. Also getting a history of any habits like smoking or grinding teeth. At this stage the patient expectations are discussed.
Step 3- is a hard tissue analysis , which means how much bone is there. If the bone is deficient then with the predictable techniques the bone augmentation can be done . A simultaneous bone graft with the implant can be done in many cases.
Step 4- is a soft tissue analysis.Here the gum type is assessed, so as to understand the final esthetics that can be achieved.
Once the above information is in place the dentist can decide if the case is appropriate for an immediate dental implant.
