A) Exposed-thread numbers at the crestal level were calculated as previously described to calculate the radiological bone loss at both mesial and distal sites of each implant. As shown in the respective radiographs for each group, zero indicates no exposure, while 2 and 3 refer to “two and three” threads exposed, respectively. Arrows depict the area evaluated for exposed implant threads. B) Based on counting of the threads exposed mesially and distally for each implant, the PA-alone group showed the highest number of threads exposed (mean ± SD: 2.6 ± 0.8; P < 0.05),† while PPCH-PA group exhibited the least number of threads exposed (0.8 ± 0.9; P < 0.001).*
