The absence of teeth is currently an urgent problem for all mankind. Dentism accounts for 15% of all pathologies of the dental system [1]; 40% of patients over 60 years old are toothless [2]. The most common is the loss of chewing teeth, mainly the first molars. 8.55% of teeth are missing in the anterior dentition, 63.19% in the lateral dentition. Dentition defects, including tooth loss, account for 71.74% of all tooth losses, with terminal defects accounting for 28.26% [3]. Currently, implantation therapy is actively used in the rehabilitation of partially and completely toothless patients. This is due to the fact that prostheses based on implants allow the most complete restoration of masticatory efficiency, lingual function and high aesthetics of the bone system of the alveolar process in comparison with other types of orthopedic treatment. In addition, it is obvious that patients adapt to prostheses faster [3-7]. In this regard, partial and complete removable plate prostheses are currently recognized as a kind of sign of dental incompetence [8-11]. Nevertheless, the problem of choosing the most rational design of the implant abutment remains unresolved: in the mid-1990s, a revolutionary CAMlog system was developed based on the IMZ system, combining all the experience accumulated over the past decades. Standardized universal parts included in this system have greatly simplified the production of restorations based on implants [14].

Nevertheless, the IMZ system, CAMlog system
