However, the ability to ensure high primary implant stability in a severely atrophied ridge is of chief concern. The purpose of this study is to measure and compare the success rate of implants placed at the time of crestal approach sinus lift in patients with \u22644\u2009mm of residual alveolar bone (\n RAB<\/jats:styled-content>\n ) and >4\u2009mm of\n RAB<\/jats:styled-content>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Materials and Methods<\/jats:title>\n \n In this three\u2010site multicenter study, one hundred two patients, 53 males and 49 females, (23\u201389 years old; mean\u2009=\u200956.2) were evaluated. Three experienced surgeons (>15 years) performed the crestal approach sinus lift microsurgeries with simultaneous implant placement. At baseline and at the follow\u2010up appointments, calibrated examiners measured radiographic interproximal bone level using\n ImageJ<\/jats:styled-content>\n for Windows after calibration of the radiographs. References for the bone level measurements were the platform, first and second threads of the implants. Statistical analyses, using\n STATA<\/jats:styled-content>\n version 12, stratified patients according to\n RAB<\/jats:styled-content>\n height (group 1:\n RAB<\/jats:styled-content>\n of \u22644\u2009mm;\n n<\/jats:italic>\n \u2009=\u200935 and group 2:\n RAB<\/jats:styled-content>\n \u2009>\u20094\u2009mm;\n n<\/jats:italic>\n \u2009=\u200967), age, gender, and treatment center.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n The success rate was 100% for group 1 and 98.51% for group 2 at 6 to 100 months postprosthetic loading (mean\u2009=\u200929.7 months). The peri\u2010implant bone loss averaged 0.55\u2009mm (interquartile range [\n IQR<\/jats:styled-content>\n ]\u2009=\u20090.5 [0\u20131]) in group 1 and 0.07\u2009mm (\n IQR<\/jats:styled-content>\n \u2009=\u20090 [0\u20130]) in group 2. There was no statistically significant difference between the two groups. Clinical outcomes were independent of age, gender, and treatment center.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n \n The\n RAB<\/jats:styled-content>\n height did not increase crestal bone loss or reduce the success rate of the implants and associated prostheses. The crestal approach should be considered a viable technique for use in patients with residual bone height of \u22644\u2009mm and merits further evaluation.\n <\/jats:p>\n
