Despite its growing popularity, alveolar distraction osteogenesis (DO) is a technically challenging operation. The purpose of this review is to estimate the types and frequencies of complications in alveolar DO and to identify factors associated with them. 26 reports of alveolar DO found in the PubMed database that met the criteria for inclusion were studied. 256 patients underwent 270 DO procedures; 109 complications arose in 77 patients (30%) with 77 distractions (29%). In 27/77 patients, more than 1 complication occurred. 20 complications (7%) were a consequence of surgery, 32 (12%) occurred during distraction, 22 (8%) during the consolidation period and 35 (13%) post-distraction. The most common complications were insufficient bone formation following the consolidation period (22 cases, 8%), regression of distraction distance (18 cases, 7%) and problems related to the distractor device (16 cases, 6%). The most severe complications occurred in 4 cases (2%). The type of device used and an augmentation rate of more than 0.5 mm/24 h were significantly related to insufficient bone formation and evidence of complications. This review indicates that complications in alveolar DO are frequent, but rarely cause severe problems or clinical decline. Appropriate treatment selection, surgical technique and adjusted protocol should decrease the number of complications.
