Brief Summary

To assess the accuracy of the computer assessed guides in horizontal bone augmentation achieved at posterior mandible using guided modified ridge splitting technique versus free hand modified ridge splitting technique

Conditions

Horizontal Bone Augmentation; Horizontal Ridge Deficiency

Keywords

computer guided modified ridge splitting; computer guided modified cortical shell technique; guided modified ridge splitting in posterior mandible

Outcome Measures

Primary Outcomes (1)

• Accuracy of the Computer Assessed Guide in the study group

  Accuracy of the Computer Assessed Guide in the study group In comparison with the control group between predicted and immediately postoperative horizontal bone width with Cone beam computed tomography in Millimeters measurement tool is CBCT scan superimposition in mm

  immediately postoperative

Secondary Outcomes (1)

• Alveolar ridge horizontal bone gain

  4 months

Other Outcomes (1)

• soft tissue dehiscience

  2 months postoperatively

Study Arms (2)

computer guided modified ridge splitting technique (study group)

EXPERIMENTAL

The first treatment plan includes harvesting and fixing the bone graft in posterior mandibular area using a computer-modified surgical guide.

Procedure: computer guided modified ridge splitting technique in horizontal bone deficiency in posterior mandible

conventional modified ridge splitting technique (control group)

EXPERIMENTAL

The second treatment plan includes manually harvesting and fixing the bone graft in posterior mandibular area without a surgical guide

Procedure: free hand modified ridge splitting technique in horizontal bone deficiency in posterior mandible

Eligibility Criteria

• Age: 25 Years - 55 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• 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

You may not qualify if:

• 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
