AIM: The aim of this research was to assess peri-implant bone remodeling of post-extractive implants over 2 years. MATERIAL AND METHODS: 30 patients meeting pre-established inclusion criteria were enrolled for the study. One implant for each patient was inserted in the post-extraction sockets according to a defined surgical protocol (atramautic extraction, curettage of extraction socket, implant insertion, grafting with collagenated cortico-cancellous porcine bone, and a trimmed collagen membrane to completely cover the socket, suture). A temporary adhesive bridge, with an adequate profile, was bonded to the adjacent teeth. X-ray evaluation with a standardized stent was carried out at different times. Measurements were obtained from the implant edge to the bone peak. The values obtained at time 0 and at 2 years were compared by t-student test. RESULT: Our results showed that after one year 73% of patient had 0 mm of bone reabsorption, 20% of patient had 0 mm ≤ x ≤ 0.5mm, 7% of patient had 0.5 mm ≤ x ≤ 2 mm of bone reabsorption. After two years 62% of patient had 0 mm of bone reabsorption, 24% had 0 mm ≤ x ≤ 0.5mm, 14% had 0.5 mm ≤ x ≤ 2 mm. CONCLUSIONS: The results showed no significant differences in bone reabsorption in most patients over 2 years.

Abstract

AIM: The aim of this research was to assess peri-implant bone remodeling of post-extractive implants over 2 years. MATERIAL AND METHODS: 30 patients meeting pre-established inclusion criteria were enrolled for the study. One implant for each patient was inserted in the post-extraction sockets according to a defined surgical protocol (atramautic extraction, curettage of extraction socket, implant insertion, grafting with collagenated cortico-cancellous porcine bone, and a trimmed collagen membrane to completely cover the socket, suture). A temporary adhesive bridge, with an adequate profile, was bonded to the adjacent teeth. X-ray evaluation with a standardized stent was carried out at different times. Measurements were obtained from the implant edge to the bone peak. The values obtained at time 0 and at 2 years were compared by t-student test. RESULT: Our results showed that after one year 73% of patient had 0 mm of bone reabsorption, 20% of patient had 0 mm ≤ x ≤ 0.5mm, 7% of patient had 0.5 mm ≤ x ≤ 2 mm of bone reabsorption. After two years 62% of patient had 0 mm of bone reabsorption, 24% had 0 mm ≤ x ≤ 0.5mm, 14% had 0.5 mm ≤ x ≤ 2 mm. CONCLUSIONS: The results showed no significant differences in bone reabsorption in most patients over 2 years.
