Sažetak
The author set himself the task of eliminating contact with the surface in endo-osseous implants and to reduce considerably the effect of the pressure and tension forces to eliminate in this way the two basic factors decisive for the poor success of an implant. He chose the front teeth in which over one third or more than one half of the root protrudes into the radicular cyst. He widened the roots and the last reamer was used as a model for the implant. The length of the implant was determined by measurements on the roentgenogram. The implant was made of vironite. After cystectomy and apicoectomy the canal of the tooth was filled with fast-binding cement. The implant was filled into the canal from the apical side while guttapercha point was simultatenously implanted from the coronary side. The wound was then closed.The following possibilities were thus created: 1. The implant had no contact with the surface, thus preventing infections from the surface. 2. The pressure and tension forces negatively affecting the process of osteogenesis and resulting in osteolysis were considerably reduced. The cause of this phenomenon is that the periodontium has been preserved on the remaining stum of the root. In this way the forces affect simultaneously Sharpey's fibers and the relatioship implant — bone. The internal implant forms an entity with the apicotomized tooth preventing injury to the periodontium and the bone, loosening of the teeth and of the implant. The tooth is accordingly immobilized partly by a fixed and partly be a flexible joint which function simultaneously. The results obtained so far are satisfactory. The postoperative course and the following period do not at all differ from ordinary apicoectomy and cystectomy. There was no rejection of the implant, no loosening of the teeth, suppuration or pain. Concluding the author mentioned that he was experimenting with two other ways of application of — as he called it — the internal implant for other purposes.
