Overall good outcomes have been reported. Nevertheless, complications such as inflammation of the skin around the percutaneous abutment, pain and implant loss are related to BAHS.For implant loss stability, primary and secondary stability are important concepts. Primary stability is defined as implant stability immediately after surgery. Dental studies show that primary stability is influenced by implant design, surgical technique, bone quantity and bone quality. Secondary stability is defined as stability over time and is determined by primary stability and osseointegration. In dental implants, osseointegration is influenced by surgical trauma, implant design, smoking status and other subject‐related factors such as diabetes and hygiene.In BAHS, implant loss rates of 8.3%‐18% have been reported. 3‐mm
