简要总结

Narrow alveolar ridges with a thickness equal or less than 5 mm requires bone augmentation procedures before or at the time of implant placement. (Anitua, Begoña, and Orive 2013) Several surgical techniques have been utilized for the reconstruction of deficient alveolar ridges such as block onlay graft augmentation, guided bone regeneration, distraction osteogenesis , ridge splitting and/or ridge expansion(McAllister and Haghighat 2007). A new bone drilling technique named Osseodensification facilitates horizontal ridge expansion. Studies are needed to validate the effectiveness of osseodensification as a lateral ridge augmentation procedure that aims at increasing the thickness of atrophic ridges, thus maintaining ridge integrity and allowing for implant placement with enhanced stability. The null hypothesis Proposes no difference in the bone width gain following the osseodensification drilling system compared to the ridge splitting technique with simultaneously placed implants in narrow alveolar ridges.

详细描述

The aim of the study is to evaluate ridge width gain in patients with narrow alveolar ridges following osseodensification as compared to ridge splitting with simultaneous implant placement using CBCT.

Interventions:

I. Pre-operative phase:

Clinical Examination:

  1. Visual examination, palpation and inspection of the entire oral and Para-oral tissues.
  2. Preoperative alginate impressions for both the maxillary and the mandibular Ridges.
  3. Full mouth scaling and root planing, followed by oral hygiene instructions.
  4. The Bucco-Lingual/Palatal alveolar ridge width measurement at site of interest using a bone caliper.
  5. Study casts will be made in order to properly evaluate the inter-arch space, occlusion type and direction of forces in regard to the site of the future implant.

入选标准

  • Patients with at least one missing tooth in need of replacement.
  • Patients having a Bucco-lingual/palatal width of the edentulous alveolar ridge less than 6 mm with a minimum of 3mm residual bone width.
  • Patients having at least 11 mm residual bone height at the proposed edentulous area.
