Coronally Advanced Flap Technique to Treat Class I and II Gingival Recession in Combination with Connective Tissue Graft or Equine Collagen Matrix: A Retrospective Study.

The research compares how effective an equine collagen matrix (ECM) and a connective tissue graft (CTG) are when treating Class I and II gingival recession using a technique called coronally advanced flap (CAF).

Objective of the Study

• The research is a retrospective study aimed at comparing the efficacy of ECM and CTG in the treatment of Class I and II gum recession using the CAF technique. The researchers studied the medical records of 50 patients to deduce their findings.

Data Parameters and Follow-up

• Four primary parameters were used to assess the effectiveness of ECM and CTG as treatments: recession depth, probing depth, keratinized tissue width, and percentage of root coverage. These factors were recorded at the start of the study and at a follow-up one year later.
• The investigators also sought to determine how many patients achieved complete root coverage following the receipt of either treatment.

Results of the Study

• Based on the parameters investigated, the study found that the results when using ECM and CTG in conjunction with the CAF technique were generally comparable. This implies that both methods could be equally effective when treating Class I and II gingival recession, when paired with the CAF surgery.
