Abstract

This study aimed to evaluate vertical and horizontal alveolar bone changes after immediate implant placement in the mandibular posterior region combined with ridge preservation and socket sealing with custom healing abutments. Material and methods: eighteen immediately placed implants were inserted in sockets of mandibular molar and the space around the implants was filled with Allograft bone material. Socket was sealed with custom healing abutment. Radiographic evaluation of vertical and horizontal alveolar bone changes were performed on CBCT images taken immediately after implant placement (T0), six months (T6) and 12 months (T12). The following distances were measured around the four implants surfaces; 1) P-BIC; from implant platform to the first bone contact, 2) P-T; vertical distance between implant platform and alveolar bone crest, 3) OBS; from buccal and lingual border of bone to the implant surface at the level of the implant platform (OBS0), 2 mm (OBS2), and 4 mm (OBS4) apical to implant platform.
Results: The highest bone loss at P-BIC and P-T distances was noted with distal surface, followed by mesial surface, the lowest was noted was buccal/lingual surfaces. At T6 and T12, Buccal surface recorded significant higher OBS0 bone loss than lingual surface.
Conclusion: Immediate implant placement in the mandibular posterior region combined with ridge preservation and socket sealing with custom healing abutments and delayed loading protocol is a successful treatment and associated with acceptable vertical and horizontal bone loss around implants after one year follow-up.
