Traditional "blind" local anesthesia in the maxilla is characterized by variability in results, a relatively late onset of pain block, and an increased risk of complications. The aim of the study was to analyze the effect of a customized navigation template on the effectiveness of local conduction anesthesia in the maxilla, measured by time characteristics and the volume of anesthetic consumed. Materials and methods: The randomized study included 100 patients (the study group, n = 50, received anesthesia via a navigation template; the control group, n = 50, used the classical manual technique). All patients underwent cone-beam computed tomography to clarify the diagnosis, and patients of the main group underwent CBCT data were used to generate bone reconstructions, which were merged with intraoral scan data for subsequent digital planning of a customized navigation template, with intraoral scans combined for subsequent digital planning of a customized navigation template. The clinical phase involved the use of an individual navigation template during various dental procedures with the assessment of the anesthesia onset time (sec), anesthetic volume (ml), extent of the anesthetized area and complications. Results and discussion. With infraorbital, tuberal, incisor and palatal anesthesia in the main group, the onset time was statistically significantly shorter (p < 0.01). The volume of the administered drug with tuberal and infraorbital anesthesia in the main group was lower (p = 0.001), for incisor and palatal – no differences were found. In the main group, 100 % isolated anesthesia was achieved, no complications were recorded; in the control group - a positive aspiration test (6 %), hematomas (4 %), pain on injection (2 %). Correlation analysis showed the effect of age on the onset time and volume of anesthetic. Conclusion. The use of a navigation template significantly accelerates the onset of anesthesia, reduces the volume of anesthetic, and improves the safety and quality of anesthesia in the maxilla.
