About this trial
Statement of problem: The stability of peri-implant bone is a crucial factor for the long-term success of dental implants, where crestal bone plays a significant role in both the primary as well as the long- term implant stability. A bone loss of 1.5 mm during the first year of loading has been acceptable according to the early standards. However, more bone stability can be expected with the development in implant designs and surfaces over the past decades.
Aim of the study: the aim of this study is to radiographically assess the crestal bone changes following delayed implant placement in mandibular previously augmented posterior sites, comparing cases with equicrestal implant placement with subcrestal implant placement
Eligibility criteria
Qualifiers
Patients older than 21 years.
Patients having augmented (by 50/50 particulate xenograft and autogenous bone) edentulous posterior site with vertical bone height of > 10 mm in the mandible with a width of ridge ≥ 7 mm
Adequate Inter-arch space for implant placement
Favorable occlusion (no traumatic occlusion).
Disqualifiers
Patients with inadequate bone volume and/ or quality
Patients with remaining roots or with signs of acute infection related to the area of interest.
Patients having systemic conditions that interfere with normal wound healing
Patients with habits that may jeopardize the implant longevity and affect the results of the study such as parafunctional habits .
