Aim. The aim of this radiological study; Cone-beam Computed Tomography (CBCT) examinations and immediate implant applications in the Mandibuler posterior region; Planning is the investigation of the conditions of the anatomical formations in the region for data collection and identification, to determine the possible complexity and / or complications during or after surgery and to determine the prognosis. Materials and methods. Four hundred and ninety-seven CBCT images of the Mandibuler region of a total of 497 patients were analyzed retrospectively. Images of Mandibuler first premolar, second premolar, first molar and second molar regions were evaluated. In this scanning study; Crest morphology (Gallucci and Posterior Crest type) and anatomical formations of the Mandibuler posterior region were evaluated. Categorical variables were presented as number of events and percentage. Chi-square test was used to compare categorical variables (p<0.05). Results. Of the four hundred and ninety-seven partially edentulous patients, 293 were female and 204 were male. In Gallucci crest type evaluation, the rates were found to be 41.5% for oblique crest, 25.2% for S-shaped crest, 19% for straight crest, 10.7% for hourglass crest, and 3.7% for basal bone crest. When the posterior crest type classification was evaluated, the rate of U (concave) crest was 35.5%, P-type 34.1%, and C-type 30.3%, respectively. In terms of implant complexity, in our study, oblique crest type was found to be higher and (U) concave crest type was found to be lower than other studies compared to other studies. Conclusions. The fact that the concave (U) crest type was found to be lower in our screening study compared to other studies means that the complication rate also decreases and it shows that we are more fortunate in terms of racial implant success. Careful evaluation of CBCT images can provide important clinical information regarding ridge shape and anatomical formations before and during implant placement. Especially the complex structure of the Mandibuler posterior region requires extra careful examination before implant application.
