Abstract

To evaluate bone loss after three years in implants placed at the implantology consult at the Egas Moniz University Clinic, relating bone loss to the type of loading (conventional or immediate load). A comparative and retrospective study, performed on a sample of 65 implants, placed in 24 of 327 patients, who attended the implantology consult at the Egas Moniz University Clinic in 2015, representing 7.3% of the study population through the measurement of distance between implant platform and bone using radiographs. Three years after implant placement with and without immediate loading there is statistically significant bone loss mesially and distally. It was found that when compared bone loss in loaded vs unloaded mesially and distally implants, there were no statistically significant differences. The bone loss of the unloaded implants was compared three years after being placed, with the bone level of the loaded implants also three years later. No significant difference was found. Although no statistically significant differences were found between bone loss in loaded implants vs unloaded mesially and distally, as it is supported by the literature, it was possible to conclude that there was, in fact, a statistically significant bone loss, mesially and distally, three years after implant placement with and without immediate loading. This may be due to poor oral hygiene, a history of periodontitis, smoking and peri-implantitis.

student of Dentistry at University Institute Egas Moniz. Her areas of scientific interests are: Surgery, Imlantology & Periodontics.

Ricardo São João, School of Management and Technology-Polytechnic Institute of Santarém; CEAUL-Centre of Statistics and its Applications-University of Lisbon

is graduate in Applied Mathematics/branch Statistics & Operational Research (CEUL,2000) and holds a M.Sc. in Applied Mathematics for Biological Sciences (ISA-UTL,2007). The interest in health area motivated him to hold the specialization course in Epidemiology (FM-UL,2011) and his doctoral thesis in Life Sciences/Bioestatistics (FCM-UNL,2015) under the topic of "Statistical methods applied to Oncology Data Modeling". Ricardo also specializes in statistics and mathematical modeling with a strong background in the areas of statistics, modeling, and statistical computing. Assistant Professor currently at the Polytechnic Institute of Santarém and at the Faculty of Medical Sciences (UNL) he teaches in undergraduate and graduate programs. He is full member of the Centre of Statistics and its Applications of Lisbon (CEAUL). The enthusiasm and passion for teaching and the challenge of modeling complex phenomena with great impact on health and welfare of the population makes he feel doubly motivated. His research interests are in: Applied Multivariate Statistical Analysis, Spatial Statistics, Biostatistics & Epidemiology.
