Objective:To observe the outcomes of dental implant treatment based on the evaluation of bone conditions using Cone Beam Computed Tomography (CBCT). Material and Methods:A total of 31 dental implants were collected for the present study. Subsequently, mesial and distal bone losses were examined, while buccal and lingual bone thickness were measured at 7 levels. Evaluation and interpretation of CBCT results was performed by 3 independent examiners. Results:The average of mesial bone loss was 1.08 mm and 1.36 mm on distal bone. Every dental implant had lingual/palatal bone on level 1 to 3, only 1 (6.5%) didn’t have bone on level 4, 3 implants (9.7%) had no bone at level 5 and 6, and 22 implants (74.2%) had no bone at level 7/implant platform. There were 8 implants (25.8%) didn’t have buccal bone at level 7, only 1 implant (3.2%) didn’t have buccal bone at level 2,4,5 and 6, and there were 2 implants (6.5%) had no buccal bone on level 3. Dehiscence / fenestration can be seen on 90% of the implant subjects. Conclusion:These bone loss condition could be consequence of several factors such as infection, diagnosis, treatment plan, and operator’s surgery skills. The implants that placed without CBCT could lead to operator miscalculation on bone condition, therefore in moderate to advanced cases, the use of CBCT should be mandatory for treatment plan.
