Leonardo Trombelli: Periodontal regeneration with the Single Flap Approach (Straumann® Emdogain)

 

Periodontitis is the most common chronic inflammatory disease seen in humans. 5 – 15% of the worldwide population suffers from severe periodontitis that may lead to tooth loss [1]. Subjects with periodontitis have a 25% increased risk for coronary heart disease when compared to periodontitis-free individuals [2].  Over the years, many treatment strategies have been devised to treat this condition by regenerating the hard and soft tissues lost due to periodontal disease or trauma. Various surgical techniques and biomaterials have been explored. With the Single Flap Approach (SFA), Prof. Leonardo Trombelli has developed a simplified but effective procedure.

Technique matters: Flap design and suture techniques are of paramount importance for maximizing the reconstructive potential of a biomaterial [3]. Watch Prof. Leonardo Trombelli’s surgical movies on the Straumann website.

Key: the adequate surgical procedure
While an adequate biomaterial contributes to the success of a regenerative treatment, an adequate surgical procedure is key. In recent years, it has been understood that the stability of the root surface-adhering blood clot is of paramount importance to ensure adequate early healing which allows for the cascade of biologic events leading to periodontal regeneration to take place. A dehiscence of the wound margin which may occur as a result of a compromised vascular supply due to surgical manipulation and/or tensile forces could jeopardize regeneration. [4] 

A simplified and effective procedure
A flap design and suturing technique which allow for stabilization of the blood clot and its protection from mechanical and microbiologic challenges is then the solution. The Single Flap Approach (SFA) is one of the techniques which fulfills such requirements. It represents a simplified procedure that allows to surgically access intrabony periodontal defects by raising a single full thickness flap (either buccal or lingual, depending on the defect extension). [5] The Single Flap Approach (SFA) leads to considerable clinical improvement [6]. It is similarly effective to the double flap (i.e., buccal and palatal) approach [7]. SFA leads to limited postsurgical recession making it a suitable option to surgically treat defects in areas with high esthetic demands [8].

Case report by Prof. Leonardo Trombelli illustrating the Single Flap Approach

At the diagnosis stage, periodontal probing indicates a deep periodontal pocket (Fig. 1). A regenera¬tive treatment based on the single flap approach technique in combination with Straumann® Emdogain® is performed (Figs. 2 and 3). Two weeks after the treatment, the soft tissue at the surgical site is in good condition (Fig.4). Probing at one year post-op indicates healthy periodontal conditions (Figs. 5 and 6, right). Courtesy of Prof. Leonardo Trombelli.

Straumann® Emdogain® (used alone or in combination with bone graft) is arguably the material of choice to treat periodontal defects. Adding Emdogain® to an open flap debridement surgical procedure has demonstrated to yield significantly better clinical results than the procedure alone . Adding Emdogain® to the procedure has also been shown to significantly reduce post-surgical pain and swelling, as well as improve wound healing .
