Abstract

Objective: Evaluate the jaw bone condition of patients with upper molars loss using cone beam computed tomography (CBCT). Methods: The study was conducted on CBCT films of 151 patients with missing upper molars and analyzed and processed to survey the size of the jawbone in the tooth loss area, as well as bone density. Results: Jaw bone size including height, width and jaw bone thickness all decreased with the number of missing teeth, in which the difference in thickness was statistically significant (p<0.05). Jaw bone height <8mm accounts for a high proportion (53.51%). The lowest jaw height (<4mm) is common at tooth number 7. Jaw bone thickness of 6-9mm prevails. Jaw bone width when losing 1 tooth is mainly 8-12mm. The majority of patients had bone type C (81.1%). Bones with density D1 and D2 are not found, while bones with density D5 predominate (71.43%). Conclusion: Researching the condition of the jawbone in the missing area, specifically the size and density of the jawbone, helps doctors plan appropriate treatment for each patient, especially in implant surgery, ensuring ensure the best results for patients
