Oral scleral heterografts. A pilot study
Oral Surgery, Oral Medicine, and Oral Pathology
|May 1, 1978
Summary
Scleral heterografts show promise for oral cavity applications, demonstrating firm attachment and minimal immune response. Further research is needed to explore their use in periodontal surgery and reconstructive procedures.
Area of Science:
- Oral surgery
- Biomaterials science
- Tissue engineering
Background:
- Scleral grafts are used in reconstructive surgery.
- Limited availability of human donor sclera.
- Need for alternative biomaterials in oral and periodontal surgery.
Purpose of the Study:
- To evaluate the efficacy and characteristics of scleral heterografts in the oral cavity.
- To assess their potential for obliterating bony defects and oroantral fistulas.
- To investigate the feasibility of using bovine sclera as a substitute for human sclera.
Main Methods:
- Scleral heterografts were implanted in oral cavity models.
- Graft characteristics such as adherence, tissue response, and vascularization were analyzed.
- Clinical acceptance and host antigenic response were evaluated.
Main Results:
- Scleral heterografts exhibited firm attachment to submucosal, periosteal, and bony tissues.
- Grafts remained fibrotic, suggesting stress-bearing capacity with minimal scarring or contracture.
- Minimal host antigenic response and evidence of vascularization and cellular integration were observed.
Conclusions:
- Scleral heterografts are a viable option for obliterating bony undercuts, cystic cavities, and major bony defects in the oral cavity.
- Their tenacious adherence makes them promising for treating oroantral fistulas.
- Further studies on scleral layering and antigenicity are essential to determine their full potential, including the use of bovine sclera in periodontal surgery.
