Abstract

Abstract:

Aim of the study: To evaluate the efficacy of umbrella technique combined with sticky bone in horizontal ridge augmentation using Buccolingual width changes measured in CBCT.

Materials and Methods: 15 male and female Patients were selected . Buccal and lingual Infiltration anaethesia to mandibular posterior area (area of interest), crestal incision flap. Decortication using round bur and straight hand piece then drilling using screw drills with 90 degrees to the buccal cotical plate. Umbrella Screw insertion using screw holder with 6 mm length and 1.6 mm diameter where 3 mm inserted in the bone and 3 mm are kept outside. The bone graft and the I PRF are placed into sterile dish, mixed together till sticky bone is formed. Application of the sticky bone buccally, on and in between the bone screws with proper condensation.

Results: At baseline, the mean radiographic bone width value was (3.31), the standard deviation was (0.87), the median was (3.75), and the interquartile range was (1.01). After 6 months, the mean was (6.08), the standard deviation was (0.78), the median was (6.33) and the interquartile range was (0.99).

For the radiographic difference after 6 months, the mean value was (2.62), the standard deviation was (0.15), the median was (2.66) and the interquartile range was (0.20). For the percentage change the mean value was (76.30), the standard deviation was (11.25), the median was (72.94) and the interquartile range was (10.60).

Conclusion: Umbrella technique using bone screws has predictable results in the horizontal ridge augmentation. Tenting of the periosteum and soft tissue using tenting screws maintains space and minimizes resorption of the particulate graft volume.
