ADVANCING THE ART AND SCIENCE OF DENTISTRY

EXTRACTION, IMMEDIATE LOAD IMPLANT WITH A BONDED “MARYLAND” FPD CROWN
“TEETH-IN-A-DAY”

Dental implants can be placed into fresh extraction sockets immediately after tooth removal. These are called “immediate implants.” Delayed implants are those placed into partially or completely healed bone. One of the main advantages of an “immediately implant” is the “loading” of it. If the loading of the implant is achievable with an aesthetic provisional crown(s), a removable plastic partial denture for tooth or teeth replacement is avoided. This loading technique shortens treatment time and preserves soft tissue contours and bone height, providing an aesthetic outcome. The disadv antage of immediate loading, although small, is an increased risk of lack of osseointegration of the immediate load implant.

PROVISIONALIZATION AND TISSUE STABILITY

Gingival tissues shape is based on tissue surrounding natural teeth. Preserving osseous architecture is the key to predicting the eventual gingival tissue position and natural aesthetics. To maintain tissue and underlying bony architecture and prevent bone loss after extraction, it is necessary to maintain socket size and shape with an immediate prosthodontic replacement. After tooth removal and insertion of an immediate implant, provisionalization can be achieved in one of several ways. A prefabricated provisional crown is attached directly to the implant. Another technique is the fabrication of a provisional “Maryland Bridge” to ensure stabilization of the immediate load implant. After insertion of a temporary abutment, the prefabricated “Maryland FPD” can be relined at the surgical site to maintain and support the soft tissue height. Occlusal adjustments are then made, and the patient is advised to avoid eating on the restoration to allow uneventful healing.

The following patient was evaluated once a week for the first month after treatment. After three months, the patient was scheduled for final restoration. The provisional aesthetic “Maryland Bridge” was removed. An impression post was inserted into the implant and the final impression was taken with an open tray technique. To fabricate the final restoration, the laboratory used an angled custom abutment with adequate space for the PFM crown. The shade was selected to match the existing teeth.

FINAL RESTORATION
After receiving the final restoration, the custom abutment was inserted into the implant and the PFM crown was luted to it with resin modified glass-ionomer cement.

Because gingival tissue possesses biological memory, preserving osseous architecture is the key to predicting the eventual gingival tissue position

CONCLUSION
The use of dental implants for immediate replacement of a missing tooth or teeth has become a well-accepted treatment option. The healing time of surgical procedures involved with traditional dental implants “in the smile zone” had been a cause of patient concern in the past. Clinical research is onging, but with the knowledge and techniques now available, the use of immediate implants with provisional crown(s) in the aesthetic zone is very acceptable. Patients now have a better option for replacing a missing tooth or teeth at the time of surgery, without the need of removable appliances and waiting for the socket(s) to heal. The immediate load implant gives patients greater satisfaction with aesthetic outcome.
