The current study aimed to evaluate both the quality and quantity of gained and maintained bone width after ridge splitting utilizing autogenic bone wedges versus mixed bone particles for horizontal ridge augmentation in the anterior esthetic zone.

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:

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

   1. The anterior maxillary vertical dimension was more than ten mm measured from the alveolar crest to the basal bone of the maxilla.
   2. 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.

2. All patients were free from any medical conditions that may affect bone healing .

3. No local pathosis that may interfere with bone healing.

4. No previous grafting procedures at the indicated edentulous ridge.

   Exclusion Criteria:

1- Patients suffering from any systemic disease that may affect bone healing. 2- Patients with less than 3mm labio palatal alveolar ridge width. 3- Ridge with inadequate vertical bone height. 4- Presence of any local pathosis that may interfere with bone healing. 5- Patients unable to continue the whole follow up.
