Summary
A modified gingival graft technique offers comparable results to conventional free gingival grafts (FGG) for increasing keratinized tissue width and thickness. This modified approach, however, significantly reduces patient postoperative pain and analgesic use.
Area of Science:
- Periodontology
- Oral Surgery
- Regenerative Dentistry
Background:
- Gingival augmentation is crucial for managing mucogingival defects.
- Conventional free gingival graft (FGG) procedures are standard but can cause patient morbidity.
- A modified FGG technique involves suturing the flap over the graft to potentially improve outcomes.
Purpose of the Study:
- To compare the efficacy of a modified FGG technique versus conventional FGG for gingival augmentation.
- To evaluate changes in keratinized tissue width (KTW) and thickness (KTT).
- To assess postoperative pain (POP) and analgesic intake.
Main Methods:
- A 12-month, multicenter parallel randomized controlled trial.
- Recruited subjects with buccal RT2 gingival recessions and KTW < 2 mm in mandibular incisors.
- Randomized 40 subjects into conventional FGG (control) and modified FGG (test) groups.
Main Results:
- Both techniques significantly increased KTW and KTT compared to baseline (p < 0.05).
- No significant differences in KTW or KTT were observed between the modified and conventional FGG groups.
- The modified FGG group reported significantly less POP and analgesic use at 7 days (p < 0.05).
Conclusions:
- The modified FGG technique is as effective as conventional FGG for augmenting keratinized tissue at mandibular incisors.
- The modified FGG technique leads to reduced patient morbidity, including less postoperative pain and analgesic consumption.
