Use of Collagen Matrix to Change Gingival Bio-type over Apicectomy
A Case Report
Ismail, Atef
Objectives: Change in keratinized mucosa due to fistula associated with periapical granuloma may alter the outcome of apicectomy procedure Aim of this study is to evaluate the possibility of use of collagen matrix (Derma® Osteobiol) to change biotype over apicectomy.
- 32 years female patient with periapical lesion related to upper left lateral incisor exhibiting fistula in the buccal surface
- Quality of keratinized mucosa assist photography and clinical using endodontic file
- Surgical removal of periapical lesion was performed according to the surgical protocol after endodontic treatment for the affected tooth
- Bony defects were augmented using bone substitute
- Fistula was surgically removed - Collagen matrix is fashioned to cover the defect size and surrounding area
- Flap suturing and antibiotic regime for 10 days
- Clinical , photographic and radiographic evaluation follow up extended for one year.
Results: Complete closure of fistula and thickened keratinized mucosa were observed demonstrating a change of biotype from thin biotype to a thick one maintained through one year follow up. Radiographic evaluation reveals successful apicectomy procedure.
Conclusion: This clinical report reveals possible change of biotype by using collagen matrix over apicectomy site. This provides secured media for successful apicectomy procedure.
