Ridge Splitting Using Autogenous Bone Wedge Versus the Conventional Intercortical Augmentation Technique in Horizontally Deficient Anterior Maxilla

This randomized clinical study included 20 patients with a horizontally deficient ridge in the esthetic region. Two groups were divided according to the type of intercortical bone graft used after ridge splitting: 10 patients for each. (The intervention group) had grafting with autogenous bone wedges harvested from the chin, and (the control group) had mixed (autogenic and xenogenic) bone particles.

Inclusion criteria

• All patients possessed partially edentulous anterior maxillary ridge with the following criteria

• The anterior maxillary vertical dimension was more than ten mm measured from the alveolar crest to the basal bone of the maxilla.
• The horizontal alveolar dimension varies from 3-5 mm at the crest and 6-8 mm at the basal part of the ridge measured from the labial cortex to the lingual cortex.
• All patients were free from any medical conditions that may affect bone healing .
• No local pathosis that may interfere with bone healing.
• No previous grafting procedures at the indicated edentulous ridge.
