Implant etrafı defektlerin kapatılmasında bistüri tekniğiyle elde edilen otojen kemik tabakaları güvenilir mi?

Abstract

Amaç: 

Bu çalışmanın amacı, keskin bir busturi yardımıyla en yakın kemik kaynağından dental implantların etrafındaki dehisens ve fenestrasyon defektinin kapatılmasındaki basit bir tekniği ve bunun klinik sonuçlarının analizini sunmaktır.

Gereç ve Yöntemler:

Aynı cerrah tarafından 750 vidalı dental implant yerleştirildi. İmplantların 112 sinde dehiscence tarzında defekt ve 23'ünde ise (% 3) fenestrasyon tarzında defekt bulunuyordu. 

15 nolu bustüri kullanılarak en yakın kortikal kemikten elde edilen kemik tabaka implant etrafındaki defecktleri kapatmak için kullanıldı. Sağ kalım oranları değerlendirildi.

Bulgular: 

135 adet implantın açıkta kalan yüzeyi, bustüri tekniği kullanılarak alınan otojen kemik ile kapatlmıştır. İmplantlar klinik bir bulgu göstermemiş ve sağkalım oranı% 100 dur.

Sonuç: 

Dental implantların dehisens veya fenestrasyon defektlerinin tedavisinde kullanılan bustüri tekniği kolay, etkili ve güvenilirdir.

Is Autogenous cortical bone sheet reliable for the management of defects around dental implants by using scalpel technique?

Abstract

Background: The aim of this study is to present a very easy technique for coverage of dehiscence and fenestration defects around the dental implantsfrom the nearest bone source by using a sharp scalpel and the analysis of its clinical results.

Materials and Methods:750 screw dental implants were inserted by the same surgeon. Exactly 112 of the (15%) implants had dehiscence defects and 23 of them (3 %) had fenestration defects. A bone sheet was obtained from the nearest available cortical bone for covering a bone defect around an implant by using a new no: 15 scalpel. Survival rates of implants were evaluated.

Results:One hundred and thirty-five exposed implant surfaces were augmented with autogenous bone, harvested by scalpel technique. The survival rate of these implants was 100% with no significant clinical finding.

Conclusion:The scalpel technique described in the present study is easy, effective and reliable for the management of dehiscence or fenestration defects of dental implants.
