Evaluation of "Tent-Pole" Grafting Technique for Reconstruction of Mandibular Ridge Vertical Defects

Evaluation of "Tent-Pole" Grafting Technique for Reconstruction of Mandibular Ridge Vertical Defects (Clinical and Radiographic Study)

The aim of this study is to evaluate clinically and radio-graphically the efficiency of "Tent- Pole "grafting technique for reconstruction of anterior or posterior mandibular ridge defects using synthetic bone graft and Platelet Rich Fibrin (PRF) membrane.

Various techniques have been described for the reconstruction of large vertical defects before implant placement . In this study we assessed the efficacy of tenting the periosteum and soft tissue matrix with titanium screws maintaining a space for the graft material in order to augment large vertical defects of mandibular ridge (anterior or posterior region) using data from 12 patients . After 6 months we assessed the increase in bone height and density.

Inclusion Criteria:

• Patients with missing lower tooth or teeth and have a related large vertical bony defect .
• Patients with about 7mm residual bone hight and requiring about 5 mm increase in the vertical height of the mandibular alveolar ridge for future prosthetic rehabilitation.
• Patients with an acceptable oral hygiene and willing to improve it

Exclusion Criteria:

• Presence of infection or local lesions.
• Parafunctional habits.
• Current chemotherapy or radiotherapy.
• Heavy smokers.
• Alcohol or drug abuse.
• Medically compromised patients with diseases that affect passively the clinical procedure or result.
