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.

Detailed 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.

Type	Name	Description
PROCEDURE	Ridge Splitting	To measure the horizontal bone width before and after implant insertion and 6 months post-op. To measure BLI measured using PA radiographs taken immediately and 6 months post-op. To measure implant stability with the resonance frequency analyzer (Osstell,Osstell USA) at time of implant placement, 3 months and 6 months post-op. To measure implant success rate. The implants used in this study: NobelActive 3.5 - 4.3mm diameter, 10 - 13 mm in length.
