Bilateral maxillary sinus augmentation was performed in 10 patients in a split-mouth design using a bobine HA (BBM) as a control and porcine HA (PBM). Six months after sinus lifting, 60 implants were placed in the posterior maxilla. The ISQ was recorded on the day of surgery from RFA at T1 (baseline), T2 (three months), and T3 (six months). Statistically significant differences were found in the ISQ values during the evaluation period. The ISQ (baseline) was 63.8 \u00b1 2.97 for BBM and 62.6 \u00b1 2.11 for PBM. The ISQ (T2) was ~73.5 \u00b1 4.21 and 67 \u00b1 4.99, respectively. The ISQ (T3) was ~74.65 \u00b1 2.93 and 72.9 \u00b1 2.63, respectively. All of the used HAs provide osseointegration and statistical increases in the ISQ at baseline, T2 and T3 (follow-up), respectively. The BBM, sintered at high temperature with high crystallinity and low porosity, presented higher stability, which demonstrates that variations in the physico-chemical properties of a bone substitute material clearly influence implant stability.<\/jats:p>","DOI":"10.3390\/ma10060644","type":"journal-article","created":{"date-parts":[[2017,6,12]],"date-time":"2017-06-12T10:27:59Z","timestamp":1497263279000},"page":"644","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Implant Stability of Biological Hydroxyapatites Used in Dentistry"],"prefix":"10.3390","volume":"10","author":[{"given":"Maria","family":"Ram\u00edrez Fern\u00e1ndez","sequence":"first","affiliation":[{"name":"C\u00e1tedra Internacional de Investigaci\u00f3n en Odontolog\u00eda, Universidad Cat\u00f3lica San Antonio de Murcia, Avda.
