The aim of this study was to evaluate the occurrence of interradicular temporary anchorage devices (TAD) loss installed to anchor canine retraction performed in association to alveolar corticotomy (AC) versus piezocision (PZ) surgeries. One hundred maxillary self-drilling TAD were installed in 50 patients who needed first maxillary premolars extractions. One week later, AC or PZ surgeries were performed surrounding the canine and the extraction sites. A group without any adjunct surgery to accelerate tooth movement was used as control. TAD stability was evaluated throughout the 6 months of canine retraction. A total of 7, 8 and 9 TAD were lost in the AC, PZ and control groups, respectively. No significant difference in TAD stability among the groups was observed (p > 0.05). Despite the increased inflammatory response due to AC or PZ, TAD stability was not compromised.
