Treatment option for deficient maxilla by bone expansion using D-shaped bone expander for implant restorations

Background: Researchers are continuously developing various implant site development techniques to improve the predictability of implant restoration. The bone expansion from osteotome is a simple technique to improve the bone width, and is mainly applied to maxillary bone. It enables the dentist to select the optimum implant location and orientation for better functional and aesthetic rehabilitation. Case Presentation: A male patient of 30 years of age with history of tooth extraction nine weeks before due to non-restorable carious tooth destruction, reported to our department of Prosthodontics wanting to replace missing 11 and 16. Clinical examination of the extracted site with digital palpation, bone mapping showed the deficient bone width in both the region for the adequate implant size and buccal soft tissue concavity in the lateral incisor region. Bone mapping revealed the underlying bone was deficient in width by 1-1.5 mm for 3.4-3.8 mm diameter implant placement. Following conventional Panoramic, peri-apical radiographs, initial clinical examinations dental implants were advised with bone expansion by osteotomes. Conclusion: The osteotome techniques are a predictable, simple alternative to complex augmentation techniques to place an implant in case of bone atrophy. The bone expansion technique is limited to maxillary the bone, with bone width deficient less than 3 mm. Since it is a single stage surgical procedure, it is advantageous for the patient for early prosthetic replacement.
