Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • posterior mandible with horizontal deficient alveolar ridge that is from 2 to 4 mm measured from the crest of the alveolar ridge buccolingually
  • Age range from 25-55 years. No sex predilection.
  • Patients free from any systemic conditions and bone metabolism diseases that might interfere with the surgical intervention, soft tissue or hard tissue healing.
  • Patients of adequate alveolar bone width.
  • Both genders males and females will be included
  • Normal vertical dimension with normal inter-arch space. The minimum number of missing teeth in the posterior mandible alveolar ridge is two adjacent anterior teeth

Exclusion Criteria:

  • Intra-bony lesions (e.g. cysts) or infections (e.g. abscess) that may retard the osteotomy healing.
  • Previous grafting procedures in the edentulous area.
  • General contraindications to implant surgery.
  • Subjected to irradiation in the head and neck area less than 1 year before implantation.
  • Untreated periodontitis.
  • Poor oral hygiene and motivation.
  • Uncontrolled diabetes.
  • Pregnant or nursing.
  • Immunosuppressed or immunocompromised
  • Heavy smokers
  • Patients undergo medication interfere with bone healing
