Careful planning is indispensable in the treatment of an edentulous jaw with implant-supported res- torations. The axes and positions of the implants must correspond to the given biological, mechani- cal and aesthetic conditions. In situations in which severe bone recession has occurred, the work of the dental team has to involve the reconstruction of the dental and the gingival tissue. The flawless reconstruction of gingival tissue requires sound teamwork,aswellasexcellentmaterialsandexcep- tional skill. Layering with the light-curing labora- tory composite SR Nexco (Ivoclar Vivadent) takes this procedure to a new level. A 37-year-old female patient presented to our practice with her teeth and the surrounding bone structure in very poor condition (Figs. 1 & 2). Numerous teeth were missing from both the upper and lower jaws. In addition, the upper jaw showed considerable bone and gingival resorption. The patient wished to have her teeth restored to regain an attractive appearance. Owing to the extensive damage, complete restoration of both jaws with implants was indicated.

During the reconstructive phase, the upper jaw had to be treated with a provisional removable denture owing to the atrophied alveolar ridge.
