concave surfaces in the alveolar area, and subtle stipplings allowed us to achieve a 3-D depth effect quickly and easily (Fig. 10). The individual layers were light cured for 20 seconds each. Intermediate curing can, for instance, be per- formed with a Quick curing light (Ivoclar Vivadent). Prior to final polymerisation in a light furnace (Lumamat 100, Ivoclar Vivadent), a glycerine gel (SR Gel, Ivoclar Vivadent) was applied on to the denture base in a covering but not too thick a coating to minimise the formation of an inhibition layer. Only minor shape correc- tions were necessary before pol- ishing the dentures. Tungsten car- bide burs are best used for this step—the inhibition layer should be removed from the entire sur- face. Finishing was achieved by first smoothing the surfaces with rubber polishers, followed by mechanical high-gloss polishing at low rotational speed using a goat hair brush, leather buff and Universal Polishing Paste (Ivoclar Vivadent; Figs. 11 & 12). Result The patient attained a revived aesthetic appearance owing to the natural aesthetics of the maxil- lary and mandibular dentures. Her smile told us that she had her self-confidence back, which was the most satisfying reward for our work. The dentures were charac- terised by a dynamic interplay of shades and natural light reflec- tions, nuanced gingival surfaces and strong, healthy-looking teeth (Fig. 13). They showed a stable fit and provided the desired suction effect. Assessment of the phonetic and functional criteria confirmed the success of the treatment. Com- pared with the preoperative situa- tion, the new dentures imparted a clearly more youthful appearance to the face of the patient (Fig. 14). 15 Dental Tribune Asia Pacific Edition | 12/2016 TRENDS & APPLICATIONS www.dental-tribune.com The Dental Tribune International Magazines Shipping Address Name Address Zip Code, City Country E-mail Date, Signature PayPal Credit Card Credit Card Number Expiration Date Security Code CAD/CAM Clinical Masters* cosmetic dentistry* implants laser ortho** roots Journal of Oral Science & Rehabilitation*** EUR 44 per year (4 issues per year; incl. shipping and VAT for customers in Germany) and EUR 46 per year (4 issues per year; incl. shipping for customers outside Germany). * EUR 12 per year (1 issue per year; incl. shipping and VAT for customers in Germany) and EUR 14 per year (1 issue per year; incl. shipping for customers outside Germany). ** EUR 22 per year (2 issues per year; incl. shipping and VAT for customers in Germany) and EUR 23 per year (2 issues per year; incl. shipping for customers outside Germany). *** EUR 200 per year (4 issues per year; incl. shipping and VAT).

Morphological aspects were also considered in the customisation of the soft tissue.—Fig. 11: The completed maxillary denture.—Fig.12: View from the reverse side: the broad functional margin in the labial vestibule would prevent the denture from shifting.—Fig.13: Customised denture in situ: it is hardly noticeable that the patient is wearing conventional complete dentures.—Fig. 14: Compared with the initial situation, the patient looks clearly younger and happier.
