Implant Survival in Immediately Loaded Full-Arch Rehabilitations Following an Anatomical Classification System—A Retrospective Study in 1200 Edentulous Jaws

This retrospective study analyzed implant survival of immediate implant-supported fixed complete denture (IFCD) treatment options (TOs) based on the level of alveolar atrophy (CC). Records of 882 patients receiving a total of 6042 implants at one private referral clinic between 2004 and 2020 were co...

Records of 882 patients receiving a total of 6042 implants at one private referral clinic between 2004 and 2020 were considered. The mean follow-up period was 3.8 ± 2.7 years. Cumulative implant survival rates (CSRs) were analyzed as a function of CCs and TOs according to Mantel-Haenszel and Mantel-Cox. Hazard risk ratios for implant loss were compared using Cox regression. Confounding factors were identified using mixed Cox regression models. The 2- and 5-year CSRs were 98.2% and 97.9%, respectively. Maxillary 2- and 5-year CSRs were lower (97.7% and 97.3%) compared to mandibular CSRs (99.8% and 98.6%) (<i>p</i> = 0.030 and 0.0020, respectively). The CC did not influence CSRs of IFCDs in the mandible (<i>p</i> = 0.1483 and 0.3014, respectively) but only in the maxilla (<i>p</i> = 0.0147 and 0.0111), where CSRs decreased with increasing atrophy. TOs did not statistically differ in terms of survival rate for a given level of alveolar atrophy. The adaption of IFCD treatments to the level of atrophy and patient-specific risk factors can result in high CSRs, even at different levels of bone atrophy.João Manuel Mendez CaramêsDuarte Nuno da Silva MarquesGonçalo Bartolo CaramêsHelena Cristina Oliveira FranciscoFilipe Araújo VieiraMDPI AGarticleedentulous mandibleedentulous maxillaimplant-supported prosthesisfull-archatrophyretrospective studyMedicineRENJournal of Clinical Medicine, Vol 10, Iss 5167, p 5167 (2021)
