This treatment concept reduced the need for addi- tional surgeries and number of implants needed to provide a fixed hybrid restoration with a first molar occlusion. A medium to high lip line was noted upon a wide smile with a bi-level plane of occlusion. Also noted was supraeruption of her maxillary and man- dibular anterior teeth (FDI: #12, 11, 21, 22 and #41–43,US:#7–10and#25–27)creatingadeepbite of6 mm(Fig.2).AClassIcaninerelationshipwasre- corded with 6 mm overjet & 6 mm overbite. Due to hermedication-relateddrymouthissue,generalised recurrent caries were noted. Periodontal probing depths ranged generally from 4–7 mm in the maxil- lary jaw and from 4 to 6 mm in the mandibular jaw with moderate to severe marginal gingival bleeding upon probing in both jaws.
