Abstract
The treatment of completely toothless patients using oral implants does not always allow the insertion of adequate number implants to ensure an fixed construction, the reasons ranging from anatomical, or health restrictions to financial limitations. Unfortunately, implant supported overdentures have not gained due popularity in Bulgaria. On one hand there is the psychological barrier of having to take out the construction from the mouth, which appears to be a hard-to-overcome idea for patients. On the other, the deeply rooted opinion that mobile constructions are low quality ones and imply low financial status, reason many patients to choose the long and at times unpredictable bone augmentation techniques like sinus lift, guided bone regeneration (GBR), block grafts, distraction osteogenesis, etc. Another drawback in the development of implant prosthetics is the lack of adequate clinical and laboratory experience for the manufacturing of telescopic prostheses, individually locked clasp prostheses, and other multicomponent removable prosthetic constructions.
