Abstract

Purpose: The use of bone graft following cyst enucleation could lead to infection so, this study was conducted to investigate impact of (e-PTFE) membrane alone without bone graft in promoting bone healing compared to the spontaneous bone regeneration after cyst enucleation.

Materials and methods: Sixteen intra-bony cysts in 16 patients (6 males, 10 females) were included. In study group (e-PTFE) barrier membrane was used alone after enucleation while, in control group the conventional technique was used. The follow up Period was 6 and 12 months postoperatively. Clinically, pain, soft tissue healing, and membrane exposure were assessed. Radiographically, CBCT scans were performed before, immediately after surgery, 6 months and 12 months postoperatively to assess change in density and volume of the defect area. Chi-Square and simple mean tests were used to statistically analyze all of the radiographic and clinical data (P≤.05).

Results: Clinically there was no statistically significant difference between the two groups in terms of pain or soft tissue assessment. Radiographically it was evident that (e-PTFE) membrane maintained buccal bony contour better than control group. In addition, presence of the PTFE membrane resulted in reaching bone density levels comparable to the surrounding normal bone compared to the control group.

Conclusions: The guided bone regeneration of jaw bone defects using expanded polytetrafluroethylene (e-PTFE) barrier membrane without grafting material is a viable treatment option that could result in more predictable outcomes regarding bone gain after jaw cysts enucleation.
