Immediate Loading of Maxillary and Mandibular Implant-Supported Fixed Complete Dentures: A 1- to 10-Year Retrospective Study
This study evaluated the success rates of 50 full-arch maxillary and/or mandibular implant-supported fixed complete dentures. After a mean follow-up time of 42.1 months, 269 implants remained in function, which corresponded to cumulative implant success rates of 85.2% and an absolute success rate of 90.6% (269/297 implants). This study suggested that higher implant failure rates might be associated with a dental history of bruxism (29.3%) vs no history of bruxism (4.6%) and surgeons with limited experience (≤5 years; 12.2%) vs surgeons with experience (2.4%).
Measurement of marginal bone level (MBL). Reference line (RL) is at the apical corner of the implant neck. Zero and positive values were given when the MBLs were at or coronal and apical to the RL. Negative values were given when the MBLs were apical to the RL.
