Five year evaluation of the excisional new attachment procedure

Area of Science:

• Periodontal regeneration and reconstructive surgery.

Background:

• The Excisional New Attachment Procedure (ENAP) is a surgical technique used in periodontics.
• Long-term outcomes of ENAP, particularly regarding new attachment and gingival parameters, require further investigation.

Purpose of the Study:

• To evaluate the long-term clinical outcomes of the Excisional New Attachment Procedure (ENAP).
• To assess changes in clinical attachment levels, pocket depth, and keratinized gingiva width 5 years post-ENAP.

Main Methods:

• A longitudinal study evaluating 56 surgical sites in patients treated with ENAP.
• Clinical measurements including free gingival margin height, pocket depth, and keratinized gingiva width were recorded pre-surgically and at 1, 3, and 5 years post-surgically.
• Patients received regular maintenance therapy approximately four times per year.

Main Results:

• A mean net gain in clinical attachment of 1.5 mm was observed at the 5-year follow-up.
• Probing depths averaged approximately 3.0 mm at 5 years post-treatment.
• While slight increases in probing depths and decreases in new attachment occurred over time, most sites showed significant improvement compared to pre-surgical levels.

Conclusions:

• The Excisional New Attachment Procedure (ENAP) provides statistically and clinically significant long-term improvements in clinical attachment and probing depths.
• ENAP, combined with consistent maintenance therapy, is an effective surgical approach for periodontal regeneration.
