Comparison Of Immediate And Delayed Maxillary Dental Implant Placement Using A Computerized Image Analysis Program - A Clinical Study

Measurement of bone density has a significant clinical use in medicine and it is based on X- ray images made with DEXA, CT, CBCT, panoramic and retroalveolar images. Aim: The aim of this clinical study was to compare the immediate and delayed implant placement by the use of computerized densitometric analysis in three time period: immediate after implant placement, after 6 months and after 12 months. Materials and methods: In this clinical study, 60 participants were divided into two groups of 30 participants, whose loss of one tooth in the premolar region of the upper jaw was replaced by the insertion of dental implant. An individually modified standard programme for computerized analysis was made, with specially designed software for measuring density of gray shadows in the region of interest (ROI) on RVG images. Results: There were statistically significant differences found in the change of the level of gray area between the immediate and delayed group in all seven regions, and at points P6 and P7. Conclusion: These results showed that the immediate technique had lower results in the first six months, regarding the shading level and bone remodeling, but the results were consistent with the results of the delayed technique one year after implant placement.
