How to Choose Plain Catgut for Your Practice
- Absorption Mechanism — Plain catgut is broken down by proteolytic enzymatic digestion of the natural collagen fibre, unlike synthetic Vicryl or PGA sutures which absorb by hydrolysis — this produces a faster but less predictable absorption timeline and a greater local inflammatory response.
- Absorption Time (5–7 Days) — Plain catgut loses most of its tensile strength within 5–7 days, making it suitable only for procedures with rapid mucosal healing, such as gingivectomy or simple paediatric extraction closure — it is not appropriate where wound support beyond a week is needed.
- USP Size — 3-0 and 4-0 plain catgut are most commonly used intraorally; 4-0 is preferred for mucosal margins requiring finer approximation and less tissue trauma.
- Tissue Reactivity — Plain catgut elicits a greater inflammatory tissue response than synthetic absorbable sutures because it is a foreign protein digested by macrophage and enzymatic activity — avoid in patients with a known sensitivity to bovine- or ovine-derived materials.
- Cost and Availability — Plain catgut remains a lower-cost alternative to synthetic absorbable sutures in the Egyptian market, making it a practical choice for high-volume, short-healing procedures such as student clinic extractions.
Catgut vs Synthetic Absorbable Sutures
| Suture | Material | Absorption Time | Tissue Reaction |
|---|---|---|---|
| Plain catgut | Natural collagen | 5-7 days | Higher |
| Vicryl (polyglactin 910) | Synthetic | 56-70 days | Low |
| PGA | Synthetic | 60-90 days | Low |

Frequently Asked Questions
What is the difference between plain catgut and Vicryl sutures?
What is the difference between plain catgut and Vicryl sutures?
Plain catgut is a natural collagen suture absorbed by enzymatic tissue digestion, while Vicryl (polyglactin 910) is a synthetic suture absorbed by hydrolysis. Catgut absorbs faster (5–7 days to lose tensile strength) but causes a greater inflammatory tissue response than the more predictable, lower-reactivity Vicryl.
How long does plain catgut take to absorb after a dental extraction?
How long does plain catgut take to absorb after a dental extraction?
Plain catgut loses the majority of its tensile strength within 5–7 days, although complete resorption can take up to 70 days. Functional wound support is effectively gone within the first week, so it is only suitable for procedures with rapid mucosal healing.
Is plain catgut suitable for all oral surgery procedures?
Is plain catgut suitable for all oral surgery procedures?
No — plain catgut is only appropriate for short-healing procedures such as gingivectomy or simple extraction closure. It is not suitable for flap surgery or procedures requiring wound-edge support beyond about a week, where a synthetic absorbable suture is more reliable.
Can plain catgut cause an allergic or inflammatory reaction?
Can plain catgut cause an allergic or inflammatory reaction?
Plain catgut is a natural collagen protein digested by the body's enzymatic and macrophage activity, which produces a greater local inflammatory response than synthetic sutures. Avoid use in patients with a known sensitivity to bovine- or ovine-derived materials.
