Radiographic Evaluation of The Labial Bone Dimensional Changes After Immediate Implant

Evaluation of Horizontal and Vertical Labial Bone Dimensional Changes After Flapless Immediate Implant Placement With and Without Bone Grafting: A 1-year Cone-beam Computed Tomography Randomized Clinical Trial.

For the dimension of the peri-implant buccal gap, a controversy is present whether complete bone formation labial to the implant. Therefore, leaving the blood clot in the large socket around implants without augmentation is questionable to result in complete bone fill and would not affect the buccal contour collapse. The aim of this clinical trial was to evaluate the labial bone dimensional changes after immediate implant placement in the esthetic zone with & without bone grafting inside the socket by using CBCT superimposition (Fusion) scans.

inclusion criteria:

1. adult (>20 years) with non-restorable maxillary teeth in the esthetic zone,
2. thick gingival phenotype,
3. intact but thin labial plate of bone (≤1mm)
4. intact palatal bone extending at least 6mm apically,
5. sufficient apical bone to attain implant primary stability (a minimum of 35 Ncm insertion torque)
6. labio-palatal socket dimension measured from the CBCT axial cut at mid-crestal part ≥5mm.
7. patients agreed to sign a written informed consent.

Exclusion criteria:

1. smokers,
2. pregnant women,
3. patients with systemic disease,
4. patients with parafunctional habits such as bruxism or clenching,
5. infected socket,
6. periapical pathosis
7. history of radiotherapy or chemotherapy within the past 2 years.
