AU - Poštić S FAU - Ristić, Ljubiša AU - Ristić L CN - OT - Telescopic partial denture OT - outer telescope crown OT - inner coping AB - Telescopic crowns and casted partial dentures can be used in many clinical cases. This study examined the impact of telescopic partial dentures on single remaining tooth continuation in a period of 10 years. Two partially edentulous patients with single remaining teeth in their jaws -single premolars in a lower jaw, and single molar in the upper jaw on the right side - were selected for the fabrication of telescopic metal-framed partial dentures. Dentures were retained on residual dentition entirely by cylinder telescope crowns. Inner telescopic crowns and metal fundaments of outer telescopic crowns were fabricated using a precious alloy (gold) (DAMCAST CC, Yadent Zhengzhou, China). The fit of the secondary outer crown copings over the primary copings was evaluated on the master casts and in the patient's mouth. Outer crowns were mechanically retained (Palavit G., Heraeus-Kulzer, Germany) in specifically designed boxes in a framework of cobalt-chromium-molybdenum alloy (Co-Cr-Mo-W, (Remanium 2000) UNS R30075, ASTM F75, ISO 5832-4) of partial dentures. Indirect light-cure composite (Sinfony™, 3M) was used for the fabrication of aesthetic axial and occlusal portions of outer telescope crowns. Acrylic-resin anatomic cross-linked artificial teeth (Optognath, Bayer-Galenika, Galenika, Serbia) were used in the set-up procedure in a semi-adjustable articulator (Artex CT, Amann Girrbach). Vital abutment teeth survived considerably long - for 10 years, in the situation of single and few tooth abutments, with at least one recall appointment after the 1st year of the therapy. Telescopic dentures provided aesthetically pleasing and comfortable effects - preventing bone loss and longer life span of the remaining premolar and molar teeth. AID - 857675
