Radiographic Evaluation of Type of Bone Graft Effect with Internal Sinus Elevation Alveolar Ridge Height

Abstract

Background: Generally, posterior maxillary prosthesis forms a major challenge because of the anatomical complexities caused by absorption process of alveolar following teeth losing and continued sinus expansion; which makes using dental implant very difficult because of deficiency of support bone is necessary to ensure stability. The need for additional procedures to compensate bone deficiency, especially the surgical process of sinus lifting.

Aim of study: This research aims to radiographic ally evaluate of internal sinus lifting (via alveolar process) by using Summers’ bone hammers design on alveo;ar ridge height, with the application of two types of bone grafts basis of pure hydroxy apatite of origin animal ( bovine ) purely (G-graft), and enhanced collagen type 1 (Unilab Surgibone).

Materials and Methods: In this research 28 implants (Semados) were applied in 6 patients (13 implants in 3 females and 12 implants with 3 males) aged between 30 and 52 years. The alveolar ridge heigprocess height ranged between 6-10 mm, from floor of the maxillary sinus. They have been raising the maxillary sinus floor by internal way with the application of G-graft with 13 implants and Unilab Surgibone with 12 implants. The implant has been monitoring radiologically for six months.

Results: The alveolar ridge height was up to 7.86 mm preoperative and reached to 10.92 mm postoperatively. The increase average reached to 3.06 mm, we found no significant differences between the use of both types of bone graft and along the observation period up to six months.

Conclusion: Internal maxillary sinus lifting with application of bone grafts and dental implants is effective and safe, and is not invasive surgery with guaranteed results for a long time.
