Ridge Expansion in the Maxillary Aesthetic Zone Using Piezo-electric Surgery

Tooth Loss Clinical Trial

Official title:
Lateral Alveolar Ridge Expansion in the Maxillary Aesthetic Zone Using Piezo-electric Surgery and Threaded Osteotomes for Immediate Implant Placement.

Clinical Trial Summary

In this split-mouth controlled study, implants placed using the alveolar ridge expansion technique will be compared to those placed in native bone with sufficient horizontal bone width.

The Piezosurgery device and Bone expanders (Mectron,Italy) will be employed in an alveolar ridge expansion technique.

Clinical Trial Description

The success rate of endosseous implant placement in native bone has been proven to be highly predictable. Reliable long term result requires sufficient bone thickness surrounding the implant's body. This is especially true in the maxillary aesthetic zone where buccal bone thickness of 2mm or more is necessary to prevent loss of buccal bone margin and maintain the integrity of the gingival architecture.

Ridge expansion technique, an alternative to bone graft, widens the alveolar ridge prior to implant placement, thus permits the preservation of buccal and lingual bone thickness.

Narrow atrophy edentulous alveolar ridges (study site) in the maxillary aesthetic zone will be split lengthwise using piezo-electric surgery (Piezosurgery, Mectron, USA). The prepared osteotomy will subsequently be expanded using threaded osteotomes (Bone Expanders, Mectron, Italy). Implants will immediately be inserted in the prepared osteotomy. In the edentulous alveolar ridges with sufficient thickness (controlled site) in the maxillary aesthetic zone, implants will be placed directly using conventional drilling technique. Outcome measures will be compared. ;
