Abstract
Purpose: This study assessed the stability of nano-coated hydroxyapatite implants in the posterior maxilla after early loading.
Materials and Methods: This study was conducted on nine patients missing at least one maxillary posterior tooth. Ten nano-coated hydroxyapatite implants were inserted in nine patients and subjected to early loading according to the secondary stability readings taken by Osstell®. The implant stability was measured at the time of implant insertion (T0), 4 (T1), 6 (T1 modified), weeks, and four months (T2) after surgery. Cone-beam computed tomography (CBCT) was performed in all patients before treatment started. Nine implants healed well, but one implant failed due to infection.
Results: The secondary stability results six weeks after implant insertion were sufficient for implant loading. Significant differences were observed between T0, T1, T1 modified, and T2.
Conclusions: Nano-coated hydroxyapatite implants are a good choice in the posterior maxilla because they allow early loading.
