Radiolucent periapical lesion in patient with osteoporosis: Recommendations for implant installation?
I have a 67 year old female patient with osteoporosis. Â I extracted #4 [maxillary right second premolar;15] due to a failed endodontic treatment and non-restorable root fracture 4 months prior. Â The tooth had an abscess and a very definite radiolucent periapical lesion visible on the pre-operative periapical radiograph. Â There was a significant buccal cortical plate defect following the extraction. I curretted the socket aggressively to remove infected material. Â I grafted with Bio-Oss and covered with a resorbable collagen membrane. Â I did not pack graft material in the very most periapical reaches of the extraction socket because I was concerned about penetrating the maxillary sinus. Â The medical history is significant for Metformin for well controlled diabetes and bisphosphonates for osteoporosis. Â She has been receiving IV Risedronate. Â I have postponed the implant installation for 6 weeks to see if the periapical ‘shadow’ disappears due to bone remodeling and continued healing. Â I am planning on installing a 10mm MIS SEVEN implant which will reach the area with the shadow.
1)Should I continue to wait and observe this shadow to see it will completely fill in with new bone?
2)Are there any special precautions I should take when I do the implant installation?
Any other recommendations would be appreciated.
