Evaluation of Vertical Height in Anterior Maxillary Sandwich Osteotomy:

Status Not yet recruiting

Clinical Trial Summary

Vertical bone height has always presented challenge for the clinicians especially in the anterior aesthetic zone. Therefore, this trial will attempt to compare whether better vertical bone height and implant placement technique can be achieved using simultaneous implant placement with the sandwich osteotomy, which is a time saving procedure performed in a single stage surgery; when compared to using fixation plates to support the segment followed by delayed implant placement.

Clinical Trial Description

Fixation plates are usually used to support the segmentalized bone segment during vertical bone augmentation using sandwich osteotomy and inlay bone grafting; to minimize movement of the bone segment and allow for new bone formation. Therefore, the aim of this study is to evaluate vertical bone height achieved at the anterior maxilla in vertical segmental sandwich osteotomy with simultaneous implant placement versus the same technique using fixation plates.

Description of Sandwich Osteotomy procedure to be done:

- A full thickness pyramidal flap with buccal paracrestal incision and two vertical releasing incisions slightly divergent to each other will be made. Then the mucoperiosteal flap will be reflected exposing the whole buccal cortical plate without reflection of the palatal mucosa.

- The palatal mucosa will not be reflected to avoid disturbance of blood supply to the mobilized segment for proper healing.

- With a Tungsten carbide disc - 1 mm in thickness and 10 mm in diameter - the alveolar bone will be segmented using a horizontal cut 3 to 5 mm apical to the crest of the ridge, and two lateral vertically oblique cuts 1-2 mm away from adjacent teeth roots slightly converging toward the alveolar crest or almost parallel to each other; thus creating a trapezoid-shaped bone segment pedicled on the attached palatal tissues.

- The horizontal and the two vertical cuts will then be revised using a set of graduated ridge splitting (fine chisels) osteotomes of sequential width and a light weight mallet to ensure that the surgical cuts are down to spongy bone.

- The segment will then be mobilized crestally, pedicled on the non-reflected palatal tissue. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
