Endoscopically controlled osteotome sinus floor elevation (ECOSFE) allows visualization of sinus membrane perforations but cannot prevent them. This technique, while less invasive, is not recommended for standard posterior maxilla procedures due to complexity and equipment needs.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Dental Implantology
  • Regenerative Medicine

Background:

  • Sinus floor elevation is crucial for dental implant placement in the posterior maxilla.
  • Traditional techniques can be invasive, necessitating exploration of less invasive alternatives.
  • Endoscopic visualization offers potential for improved control during sinus augmentation.

Purpose of the Study:

  • To quantify vertical bone gain using endoscopically controlled osteotome sinus floor elevation (ECOSFE) with simultaneous implant placement.
  • To assess the incidence of sinus membrane perforations during ECOSFE procedures.
  • To evaluate the outcomes of implants placed in augmented sinus sites.

Main Methods:

  • A prospective study involving 18 ECOSFE procedures with simultaneous implant placement.

  • Augmentation materials included beta-tricalcium phosphate (beta-TCP) or autogenous bone.
  • Implants ranging from 10-16 mm were placed in residual alveolar crests averaging 6.8 mm.

    • Main Results:

    • Significant bone gain was achieved, with implant lengths substantially exceeding residual crest height (P < .0005).
    • One sinus membrane perforation occurred, successfully repaired.
    • Two implants were removed due to mobility; endoscopic findings included misplaced beta-TCP and polypoid mucosa.

    Conclusions:

    • ECOSFE allows visualization but not elimination of sinus membrane perforations.
    • The technique is technically demanding and requires extensive equipment, limiting its recommendation for standard use.
    • ECOSFE is suggested for confined use in scientific trials.
