technology DeNtaltribuNe|april-June, 201022 Endosseous implant treatment has been widely reported as a highly predictable treatment modality with a low percentage of clinical complications. Pru- dent clinical judgement and careful consideration of the risks and benefits of various treatment options are essential for the treatment planning and long-term success of prostho- dontic treatment.1 Traditional implant prosthe- ses are commonly fabricated using acrylic resin teeth sup- ported by a metal framework. Significant space is designed at the tissue surface of the pros- thesis to enhance oral hygiene maintenance. However, application of this prosthetic design in the maxil- lary arch is occa-sionally esthe- tically inadequate and speech may be compromised. Conventional porcelain-fus- ed-to-metal restorations require the placement of labial restora- tion margins below the free gingival margin in order to mask the hue and value transition be- tween the sub-gingival implant sub-structures and the supra- gingival crown restorations. From a periodontal point of view, sub-gingival placement of restoration margins is related to adverse periodontal tissue response.2–5 As a result, restora- tion margins are best placed coronally from the free gingival margin.4,5 Porcelain-fused-to-metal re- storations are commonly used in the posterior teeth because of their well-documented long- term clinical track record.6–13 CAD/CAM ceramic-based mate- rials are prescribed nowadays, owing to their demonstrated promising physical properties 14,15 and clinical longevity.16 This article describes the clinical application of high- strength zirconium oxide resto- rations in the prosthodontic management of an edentulous maxilla with a failing implant prosthesis. Clinical report A 62-year-old female with an implant-supported maxillary prosthesis was evaluated at the Specialist Dental Group in Sin- gapore. She presented clinically with a maxillary fixed complete denture supported by six endos- seous implants (Nobel Replace, Tapered Groovy, Nobel Biocare). The prosthesis had acrylic resin teeth supported by a gold alloy metal framework. The implantatthepatient’smaxillary right canine area was exposed. The patient reported no symp- toms (Fig. 1). An occlusal exa- mination revealed a stable maxi- mal intercuspation position with insignificant centric rela- tion to maximal inter-cuspation slide at the teeth level. A canine- guided occlusal scheme was noted. No parafunc-tional habits Complete maxillary implant prosthodontic rehabilitation with a CAD/CAM-fixed prosthesis By Neo Tee-Khin, Ansgar C.
