Brief Summary:

Overcoming the vertical and horizontal bone deficiency in the posterior maxillae are considered as the most challenging scenarios for implant-supported oral rehabilitation in modern implant dentistry. Therefore, a comprehensive and precise understanding of such anatomical structures are needed to avoid potential complications that ultimately might jeopardize the treatment outcome.

Cone-beam computerized tomography (CBCT) offers some advantages to conventional CT-scan such as lower-dose radiation with high isotropic spatial resolution and cost. Therefore, it offers a viable and reliable tool to study anatomical structures such as the posterior atrophic maxillae


Condition or disease Intervention/treatment
Bone Deficiency, Posterior Maxillae Radiation: Cone-beam computed topography

Study Type : Observational
Estimated Enrollment : 150 participants
Observational Model: Cohort
Time Perspective: Retrospective
Study Start Date : July 2016
Estimated Primary Completion Date : September 2016
Estimated Study Completion Date : October 2016

Intervention Details:
  • Radiation: Cone-beam computed topography
    This study used a retrospective database of preexisting data that included patients treated as part of routine periodontal and oral surgery therapy for each patient's needs. All the patients signed an inform consent approving using their radiographic data for research purposes.


Primary Outcome Measures :
  1. Lateral wall thickness [ Time Frame: One month ]
  2. Residual ridge height [ Time Frame: One month ]
  3. Palatonasal recess [ Time Frame: One month ]

Study Population
This study used a retrospective database of preexisting data that included patients treated as part of routine periodontal and oral surgery therapy for each patient's needs. All the patients signed an inform consent approving using their radiographic data for research purposes.
Criteria
  • Images were included if:

    1. Pristine maxillary posterior atrophic ridges (between premolars and molars) as a result of missing single or multiple teeth for over than 12 months.
    2. Residual ridge height (RH) was < 10 mm.
    3. Presence of teeth adjacent to or opposing the edentulous area so the location of the edentulous ridges corresponding to the tooth site could be identified.
    4. The maxillary sinus to be measured was visible from its floor to at least 15 mm from the alveolar crest of the edentulous ridge.
  • Images were excluded if:

    1. Images were unclear or incomplete due to scattering or other reasons
    2. Edentulous ridge height was more than 10 mm
    3. Ridge preservation/augmentation simultaneous/delayed to tooth extractions
    4. Grafted maxillary sinus for implant-supported prosthesis
    5. The location of the edentulous ridge cannot be determined
    6. Implants or other prosthetic device restoring the posterior ridge
    7. Presence of sinus pathology that made the measurement impossible
    8. The outline of the edentulous ridge cannot be identified due to low 'grey scale' density
