do not align properly (Figure 1). The extraoral examination showed high lip mobility and the need for denture exten- sion for sufficient facial support. The intraoral examination revealed severely atrophicmaxillary andmandibular alveo- lar ridges. The radiographic findings showed completely edentulous maxilla and mandible with minimal (maxillary anterior region), moderate (mandible), and severe (maxil- lary posterior) atrophy of residual alveolar ridge in the re- spective edentulous areas. The right maxillary sinus also showed signs of acute sinusitis (see Figure 1e).

A 46-year-old woman presented to the clinic seeking implant-assisted treatment options.

The chief complaints were that she shows too much pink area of her dentures while smiling, and her teeth

The treatment risk for the maxillary milled bar overdenture was assessed using the SAC Assessment Tool highlighting key general health, full-arch esthetic, surgical, and prosthet- ic risk factors resulting in an overall treatment risk (Figure 2).
