This is due to severe alveolar bone resorption of the affected tooth, which leads to food impaction with adjacent teeth after repair, affecting the long-term stability and functional recovery of the implant. 3) Implant-crown integration and occlusal relationship: The implant crowns seem to have good occlusion with surrounding teeth, which is crucial for chewing function and long-term comfort. 4) Bone structure around implants: The bone structure around the implants appears stable on the images, showing no signs of bone absorption, which is a positive indication of implant success. 5) Shape and proportion of crowns: The installed crowns match the shape and proportion of natural teeth, contributing to aesthetic preservation and functionality. 6) Impact of missing upper first molar on occlusion: The absence of the 16th tooth may affect the distribution of occlusal forces on that side, and it is recommended that further restoration be needed in the later stage. 7) Soft tissue condition: The health of soft tissues is challenging to assess in such images, but there are no apparent signs of alveolar bone or gingival inflammation. 8) Overall oral functionality: From the images, it appears that the patient's oral restoration is nearing completion, but the impact of the missing tooth (16) on overall functionality should be considered. Figure 4 The CT image from March 20, 2016 shows that most of the implants have already been fitted with dental crowns Figure 5 The CT image from September 11, 2016 shows that all implants have crowns installed, but one tooth is missing in position 16 of the upper jaw
