Evaluating the Effectiveness of the Original Designs of Immediate-Prostheses after Multiple Tooth Extraction: Clinical Cases

Background. Rehabilitation of patients with chronic periodontal diseases leading to multiple tooth loss can be carried out using the method of immediate prosthetics. However, the likelihood of atrophy of denture-supporting tissues under non-physiological load with removable dental prostheses imposes special requirements for their design features.

Case description. Two patients seeking for dental surgical and prosthetic treatment for the diagnosis of chronic generalized periodontitis were treated in the dental clinic of Ryazan State Medical University named after academician I.P. Pavlov. Patient A. was mounted immediate prostheses made using additive technologies with the original design of the drug reservoir. Patient B. was mounted immediate prostheses with bases made of acrylic plastic, border ring of elastic polymer, and a drug reservoir made of polymethyl methacrylate. Patients underwent tooth extraction with immediate prosthetics. Patients were followed for 21 days. Criteria for the effectiveness of treatment included visual and palpatory control of extraction sites with a planimetric wound size analysis, assessment of microcirculation at the extraction site, control of the drug persistence in the reservoirs of prostheses.

Conclusion. The observations at the stages of prosthodontic treatment revealed that immediate prostheses made with the help of 3D modeling and printing technologies resulted in a normal course of healing after tooth extraction with the normalization of microcirculatory parameters at the surgical wound sites. When using combined prosthetic structures, healing of postoperative wounds also proceeded favorably, however, congestion in the microcirculatory system was noted.
