NCT07182929

Brief Summary

The goal of this retrospective study is to compare the radiographic outcomes of deproteinized porcine bone mineral (DPBM) and deproteinized bovine bone mineral (DBBM) following lateral sinus floor augmentation (LSFA) with simultaneous implant placement. The main questions it aims to answer are: Does DPBM show greater graft resorption than DBBM at 6 months postoperatively? Do both materials achieve comparable bone quality and osseointegration outcomes despite differences in resorption rates? This is a retrospective, single-center cohort study. Participants included 56 patients (56 sinuses) who underwent LSFA with either DPBM (test group, n=28) or DBBM (control group, n=28) and had complete cone-beam CT scans taken preoperatively, immediately postoperatively, and at 6 months post-surgery. Radiographic parameters such as bone height, augmentation volume, and bone texture features were analyzed to evaluate graft stability and new bone formation.

Outcome Measures

Primary Outcomes (4)

  • Apical Bone Height (ABH)

    The vertical distance (mm) from the implant apex to the most apical point of the graft material

    immediately postoperatively (T1), and 6 months postoperatively (T2)

  • Bone Height (BH)

    The vertical distance (mm) from the implant shoulder to the most apical point of the graft material. Site-specific measurements were denoted as buccal (bBH), palatal (pBH), mesial (mBH), and distal (dBH) bone heights

    immediately postoperatively (T1), and 6 months postoperatively (T2)

  • Endo-Sinus Bone Gain (ESBG)

    The vertical distance of the augmented bone along the longitudinal axis of the implant, from the sinus floor to the most apical point of the graft

    immediately postoperatively (T1), and 6 months postoperatively (T2)

  • augmented volume (AV, mm³)

    The augmented volume (AV, mm³) was measured at both T1 and T2 and was analyzed with the segmentation function of 3D Slicer 5.8.1

    immediately postoperatively (T1), and 6 months postoperatively (T2)

Secondary Outcomes (1)

  • Peri-Implant Bone Level (PBL)

    immediately postoperatively (T1), and 6 months postoperatively (T2)

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients who received LSFA with simultaneous implant placement from June 2022 to June 2024 at the Stomatology Hospital, Zhejiang University School of Medicine, were screened for eligibility. All patients underwent preoperative clinical, radiographic examinations and laboratory tests. Eligible patients subsequently received LSFA performed by experienced implant surgeons following the standardized surgical protocol.

You may qualify if:

  • Aged between 18 and 80 years;
  • Single or multiple missing teeth in the posterior maxilla with a healing period of at least 3 months;
  • Complete baseline data and surgical records;
  • Underwent LSFA with simultaneous placement of a single implant, grafted exclusively with either DBBM (Bio-Oss®, 0.25-1.0 mm, Geistlich Pharma AG, Wolhusen, Switzerland) or DPBM (THE Graft®, 0.25-1.0 mm, Purgo Biologics, Seoul, Korea);
  • Available CBCT images obtained preoperatively (T0), immediately postoperatively (T1), and at 6 months postoperatively (T2);
  • RBH ≤6 mm shown by CBCT at T0 at the edentulous site;
  • No systemic disease, untreated periapical pathology or active periodontitis;
  • Provision of written informed consent for the implant surgery by the patient or their legal guardian.

You may not qualify if:

  • Uncontrolled systemic diseases or any bone-metabolism diseases;
  • Pregnancy or lactation;
  • Head and neck radiation therapy within the past 5 years;
  • acute and chronic inflammation in the maxillary sinus;
  • Additional vertical or horizontal bone augmentation procedures besides LSFA;
  • Use of graft materials other than the specified DBBM or DPBM, or use of composite grafts;
  • Heavy smoking (≥20 cigarettes/day), alcohol abuse, or history of substance abuse;
  • Placement of multiple implants in the same grafted site (excluded to avoid within-patient confounding).
