Objective:The aim of this study was to compare preliminary the different systems of implants from FAEPO and APCD specialization clinic ÇƒÏ Araraquara, S.P. Methods:Data were obtained from 253 patients under treatment and 24 were smokers. Results:A total from 776 implants were placed (636 cylindrical, 81,64%, and 143 conic, 18,36%). For the cylindrical implants there was predominance on the implants placed at mandible (53,3%). Dimensions most used for cylindrical implants were length from 13mm (31%) and 10mm (25%) and diameter from 3,75mm (58%) and 4,0mm (26%). For the conic implants there was predominance on the implants placed at maxilla (81,81%), and the dimensions most used were length from 15mm (36%) and 13mm (34%) and diameter from 4,3mm (48%) and 5,0mm (22%). After 1 year 10 implants (1,3%) showed loss of osseointegration, 3 from smokers patients, 9 cylindrical implants and 1 conic implant. Survival of cylindrical implants was 98,59% and of conic implants was 99,31%. The qui-square test showed no differences between survival of conic and cylindrical implants (p=0,788). Conclusion:There are no differences on survival of conic and cylindrical dental implants on a short time analysis.
