دراسة توسيع الحافة السنخية و الامتصاص العظمي العمودي حول الزرعة السنية بتقنية فلع العظم حسب نظام فولمر-فالنتين

Abstract EN

Background & Objective: Existing bone loss still remains an important challenge when implant placement is required to rehabilitate the compromised site.

A new way to place dental implants in cases of alveolar atrophy, described in some articles, is the ridge-splitting technique, which allows the ridge to be widened by a less invasive procedure than the traditional grafting approaches.

The aim of this study is to evaluate the efficiency of this technique in bone augmentation, evaluate the relationship between peri-implant alveolar bone loss after Use of the Bone Splitting Technique, and to study the alveolar ridge width before and after split.

Material & Method: The sample of this study consists of 10 patients(2 females, 8 males), aged (27-62) years, affected by horizontal alveolar ridge atrophy, were treated by means of bone splitting technique and expansion of the posterior ridge of both maxilla and mandible.

Alveolar ridge width was measured before and after splitting (3 months), although pri-Implant alveolar bone loss was measured clinically (3 months) later, and on Digital Panoramic X-rays photos.

A 12- 32 month follow-up period study, mean follow-up was 22.3 months.

T and Person tests were used for statistical study.

Results: AT P<0.05 The study showed no relationship between initial alveolar ride width and Peri-implant vertical bone loss after use of bone splitting technique, it although showed a significant increase in alveolar ridge width after 3 months, the study also showed significant differences in bone loss after 3months and the following period (22.3) months.

Conclusions: Within the limits of this study, bone splitting technique appeared to be an important technique to treat narrow ridges, there’s no relationship between initial alveolar ride width and Periimplant vertical bone loss after use of bone splitting
