A 55-year-old male patient in good health presents with a fully edentulous upper arch. The patient reports wearing a full upper denture for about 5 years. He states he is unhappy with his denture and only wears it if he is out in public. The patient is specific in asking for a denture that does not cover the roof of his mouth and will stay in place without adhesives. All treatment options were presented, and the patient elects to proceed with an implant supported maxillary overdenture.

Clinical examination suggests a thick maxillary ridge, however with a CBCT scan (i-CAT FLX), the ridge is shown to be atrophied in the buccal lingual dimension. With this diagnostic information, treatment planning was finalized to use 6 LODI 2.9 mm implants (Zest Anchors) for the case. 

Six osteotomies are made with a 1.6-mm pilot bit. Each implant is removed from the sterile vile with the handpiece driver and seated to full length. Due to the aggressive design of the implant, the bone could be compressed and condensed and over 35 ncm of initial stability was attained. The LOCATOR attachments are placed on the implants and torqued to 30 ncm.

The existing denture is adjusted to seat passively over the attachments. The denture is then relined with a soft reline material Ufi Gel SC (VOCO). The patient will continue to use the existing denture during the healing phase and while the new overdenture is being made.

After 10 weeks of healing, the overdenture process begins. Impressions were taken and sent to a commercial lab that is well-equipped to handle implant cases (Burbank Dental). The wax setup with a cast frame for structural support was sent back for a try in. The setup was placed and checked for frame fit, occlusion and esthetics. When finalized, Burbank processed the denture leaving space in the acrylic to add the LOCATOR (Zest Anchors) housings chairside. The housings are placed on the LOCATOR attachments and blue Fit Test C & B (VOCO) was added to blockout any undercuts. A self-curing pickup material Quick Up (VOCO) was placed in each well of the denture and placed over the housings. When set, the denture is removed and the attachment housings are now part of the denture. Any excess material is smoothed and any voids are filled in with a novel pink colored light cured composite included in the Quick Up kit.
