Bone Resorption
Conditions
Brief summary
Using autogenous Chin block for vertical augmentation with simultaneous implant placement at anterior maxilla region comparing between the Onlay and Inlay grafting techniques.
Detailed description
to study the vertical augmentation with simultaneous implant placement at anterior maxillary region. * P: Patient requires implant at anterior maxillary ridge with vertical deficiency. * I:Inlay Sandwich Technique with immediate implant placement. * C:Onlay autogenous graft immediate implant placement. * O:Outcome name Measuring device Measuring unit Primary outcome: Vertical bone gain CBCT Millimeter -Secondary outcome(a): Crestal bone loss CBCT Millimeter
Interventions
\* Local anesthesia with vasoconstrictor(V.C) used for hemostasis. chin block graft * Scrubbing and draping of the patient will be carried out in a standard fashion using betadine surgical scrub. * The donor site is usually the chin area, its approached using local anesthesia with VC at symphysis region. * Low vestibular incision exposing the symphysis area to the inferior border of the mandible. * Using fissure bur to harvest the graft for the defect. * Closure using vicryl 3-O sutures.

Inclusion criteria
* \* Patients with partially edentulous anterior maxillary ridges. * Patients were free from any systemic disease that interferes with bone healing. * Absence of local pathosis at anterior maxillary area. * No history of any grafting procedure at the designated edentulous ridge. The edentulous ridge vertical dimension was less than 10 mm measured from the alveolar crest to the nasal floor (i.e.ridge had vertical inadequacy) with normal horizontal alveolar dimension or patient with Increased Inter-Arch Space.
Exclusion criteria
* \* Patient with fully dentulous maxilla. * Pregnant females. * Presence of bad habits (severe bruxism, clenching). * Systemic diseases that may interfere with bone healing.e.g. uncontrolled Diabetes.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| vertical Bone gain | 6 months | * The nasal floor will be used as a fixed reference by adjusting the cross sectional long axis in the center of the area of interest and bisecting it (showing the buccolingual dimension). * All the patients will wear the radiographic dentures with radiopaque material (barium sulphate mixed with acrylic powder) filling the teeth at the area of interest to ensure that the calculations were taken at the same region. * On the cross sectional view of CBCT and at each proposed implant site, a line will be drawn starting from the crest of the ridge till the nasal floor. The height will be recorded preoperatively, immediately (1 week) and 6 months postoperatively.the difference between them in millimeters will be recorded. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| crestal bone loss | 6 months | crestal bone loss around the implant will be measured in millimeter after 6 months |
