New Method to Increase Inter-alveolar Height With Preservation of Crestal Cortical Bone for Implant Treatment
The aim of this technique is to provide adequate interocclusal distance (3 mm) allowing preprosthetic management. A bone block was cut with piezosurgery and extracted, leaving the crestal cortical bone intact. The free crestal alveolar bone was fixed to the maxilla with 2 dental implants. After 3 months of follow-up, abutment surgery was performed and osseointegration was evident with adequate interocclusal height (7 mm) allowing prosthetic management.
(a) Bone block was extracted in the middle of the alveolus and coronal bone segment was left. (b) After osteotomies, coronal and basal segment were drilled together and two segments were fixed with two intraosseous implants. Primer stability was good at both of implants. (c) Autograft and fibrine-rich plasma was on the segments. (d). Increased vertical occlusal height is seen.
