This case report describes Clark’s technique of vestibuloplasty to treat shallow vestibule and, in addition, the use of free gingival autograft to augment attached gingiva to treat Miller’s recession. Vestibuloplasty is performed to deepen a shallow vestibule. Different vestibuloplasty techniques are used to deepen the shallow vestibule by modifying the soft tissue attachment. A 29-year-old male presented to the Department of Periodontics and Oral Implantology, Regional Dental College, Guwahati, India with the chief complaint of bleeding from the lower anterior along with the gingival recession. Maintenance of regular oral hygiene was an added hindrance. The combined technique of vestibuloplasty and use of free gingival graft was performed to achieve dual benefits of increasing the vestibular depth and attainment of a thick gingival phenotype.
A radiant smile results from a healthy body and emotional well-being. The overall smile aesthetics is governed by many factors, such as gingival tissues, form, and position of the teeth [1]. Periodontal plastic surgery plays an important role in enhancing the overall aesthetics. Periodontal plastic surgery, apart from being used as an aesthetic procedure, is also used for improving the maintenance of regular oral hygiene [2]. One such common problem is the shallow vestibule. A shallow vestibule hinders the maintenance of oral hygiene, which leads to incomplete removal of plaque deposits [2]. Sometimes the muscular traction provided by the vestibule can be a causative agent for the development of gingival recession. The presence of a labial frenal attachment can be an additive factor leading to further gingival recession. The depth of the vestibule is measured from the coronal part of the attached gingiva to the muco-buccal fold [3]. Vestibuloplasty is performed to deepen a shallow vestibule. Different vestibuloplasty techniques are used to deepen the shallow vestibule by modifying the soft tissue attachment. This case report describes Clark’s technique of vestibuloplasty [4] to treat the shallow vestibule and, in addition, the use of free gingival autograft to augment attached gingiva to treat Miller’s recession.
A 29-year-old male presented to the Department of Periodontics and Oral Implantology, Regional Dental College, Guwahati, India with the chief complaint of bleeding from lower anterior and gingival recession. The patient also had a complaint of not being able to maintain routine oral hygiene due to a shallow vestibule, which prevents the movement of the toothbrush. Following routine examination, it was found that the patient had no previous dental history and was not having any tobacco chewing habits. The patient had a shallow vestibule and the tension test was positive in relation to the lower anterior. Bleeding on probing was present along with gingival recession (Miller’s Class I) in relation to 41, 42, and 31. The patient was suggested vestibuloplasty for treatment of the shallow vestibule along with free gingival autograft to augment the thin attached gingiva following phase I therapy, which included full mouth scaling and gingival curettage in the lower anterior. Pre-operative images are shown in Figure 1 and Figure 2.
Gingival curettage was followed specifically for the lower anterior to treat gingivitis, which occurred due to recurrent deposits of plaque as the patient was not able to maintain his routine oral hygiene. For vestibuloplasty, a horizontal incision was placed at mucogingival junction with respect to 43,42,41,31,32, which was followed by supraperiosteal dissection up to the desired vestibular depth. The mucosa on the labial side was then undermined. The vestibuloplasty incisions are shown in Figure 3.
A free gingival autograft was harvested from the palate (Figure 4), the primary purpose of which was to achieve more attached gingiva and to obtain a thicker gingival phenotype.
The free gingival autograft was stabilized using a 5-0 resorbable Vicryl suture (Ethicon, Inc., Raritan, New Jersey, United States) (Figure 5) and the undermined area of the mucosa was also sutured at the desired level of the vestibule. Sling sutures were used to stabilize the free gingival graft whereas the mucosa was sutured back by using simple interrupted suture at the desired level of the vestibule.
A sterilized tin foil is placed to prevent the adherence of COE-PAK™ (GC Corporation, Tokyo, Japan) to the surgical site (Figure 6, Figure 7). COE-PAK acts as a physical barrier protecting the wound from the oral environment.

The Coe-Pack was removed after 14 days. A post-operative evaluation was done after two weeks (Figure 8, Figure 9).
A post-operative evaluation was done again after three months (Figure 10, Figure 11).
Periodontal plastic surgery techniques that were earlier included in the definition of mucogingival surgery are widening of the attached gingiva, deepening of the shallow vestibule, and resection of an aberrant frenum. Deepening of shallow vestibule by vestibuloplasty is a widely-performed technique [5]. Achieving the widening of the attached gingiva and augmenting the thin gingival phenotype along with obtaining a deeper vestibule for maintaining routine oral hygiene is the primary aim of this case. The main reason for having a shallow vestibule is ridge resorption following the extraction of tooth. Other factors relating to shallow vestibule can be firm muscle pull/insertion by positive frenal attachment [6]. This case presents as a gingival recession, which is because of the frenal pull in the lower anterior. Also, the patient had a thin gingival phenotype and a shallow vestibule. Both can lead to the accumulation of plaque in the lower anterior and the possibility of having further recession in the lower anterior also increases [6].
Vestibuloplasty techniques can be broadly classified as mucosal advancement vestibuloplasty, secondary epithelization vestibuloplasty, and grafting vestibuloplasty (Table 1) [7].
Mucosal advancement vestibuloplasty depends on the height of the bone and the extent of free mobile mucosa along with the vestibule so that adequate deepening can be achieved [8]. If there is an absence of free mobile mucosa along with the vestibule, the secondary epithelization technique has a better prognosis [9 ]. Kazanjian’s technique (1924) was the foremost technique described in the literature for vestibuloplasty. The disadvantage associated with Kazanjian’s technique is extensive scarring of the lip. This scarring is mainly because of the labial flap, which is pedicled off the alveolar process and used to cover the alveolar bone side. The labial surface heals by secondary epithelization. Clark (1953) recommended flap be pedicled off the lip and the raw area be left on the alveolar side rather than the labial side [10]. The disadvantage of Clark’s technique is its unpredictability in maintaining the vestibule depth. Clark's technique, which heals by secondary epithelization mechanism, can cause reinsertion of detached muscles to their preoperative levels, causing a relapse in vestibular depth [9]. In this case, besides Clark’s technique of vestibuloplasty, a free gingival graft harvested from the palate was used to augment the thin gingival phenotype and prevent further recession. Details of literature on free gingival graft are given in Table 2.
The periodontal phenotype has been proposed to replace the term gingival biotype [18]. The term periodontal phenotype, first proposed by Müller and Eger, includes the three-dimensional gingival volume and thickness of the buccal/facial bone plate [19]. The free gingival graft will help in the prevention of further recession [20]. Lesser invasive procedures like the use of collagen matrix-like Geistlich Mucograft® (Geistlich Pharma AG, Wolhusen, Switzerland) and Mucoderm® (botiss medical AG, Berlin, Germany) can be used as an alternative to autogenous grafts like free gingival grafts for the treatment of such similar scenarios [13].
This case report shows the successful outcome of vestibuloplasty in the anterior mandible. The combined technique of vestibuloplasty and the use of free gingival graft have dual benefits of increasing the vestibular depth and attainment of a thick gingival phenotype. The deeper vestibule will make routine oral hygiene possible and prevent the accumulation of plaque.
