A healthy 55-year-old edentulous male presented with concerns over his loose mandibular complete denture. After having it fabricated, he indicated that he never felt confident in chewing harder foods. He sought out our office because we offer minimally invasive narrow diameter implants to stabilize loose dentures

Since the patient was interested in having maximum stability for his mandibular denture, a cone-beam CT scan (CBCT) was ordered to determine if bone volume allowed a broad distribution of implant placement. While implants could have been placed without the use of a computerized surgical guide, using a guide ensures precise placement with maximum A-P spread.

A CBCT scan of the patient was made using cotton rolls for occlusal and soft tissue separation, and a radiopaque polyvinyl siloxane (PVS) was applied to the intaglio of the mandibular complete denture. A second scan of the denture was also made and a subsequent dental cast fabricated from the radiopaque PVS impression.

Four 2.9 mm x 12 mm Zest LOCATOR Overdenture Implants (LODI, ZEST Anchors) were planned in the computer software (Invivo, Anatomage) and a guide (Anatomage Guide, Anatomage) was fabricated. Implants were placed using a minimally invasive technique and attached to the denture the same day using an overdenture attachment material (CHAIRSIDE, ZEST Anchors).

When the patient was seen for recall 2 weeks later, the tissues were fully healed. During the 6-month recall, a CBCT scan was made to verify implant healing and integration and to assist in planning additional maxillary implants.
