Soft Tissue Grafting Procedures before Restorations in the Esthetic Zone: A Minimally Invasive Interdisciplinary Case Report

An esthetically pleasing smile is a valuable aspect of physical appearance and plays a significant role in social interaction. Achieving the perfect balance between extraoral and intraoral tissues is essential for a harmonious and attractive smile. However, certain intraoral deficiencies, such as non-carious cervical lesions and gingival recession, can severely compromise the overall aesthetics, particularly in the anterior zone. Addressing such conditions requires careful planning and meticulous execution of both surgical and restorative procedures. This interdisciplinary clinical report presents a complex case of a patient with esthetic complaints related to asymmetric anterior gingival architecture and severely discolored and eroded maxillary anterior teeth. The patient was treated using a combination of minimally invasive ceramic veneers and plastic mucogingival surgery, resulting in a successful outcome. The report emphasizes the potential of this approach in achieving optimal esthetic results in challenging cases, highlighting the importance of an interdisciplinary team approach in achieving a harmonious balance between dental and soft tissue aesthetics.


Introduction
Dental esthetics play a crucial role in modern society, as an esthetic smile is associated with kindness, popularity, intelligence, and high social status [1]. Achieving an aesthetically pleasing smile requires a harmonious balance between various intraoral and extraoral elements, including the lips, teeth, and gingival tissues [2][3][4][5][6]. Gingival esthetics, also known as "pink esthetics", is a critical determinant of overall dental esthetics, as they frame any esthetic restorative work performed on the teeth [1]. Therefore, conditions such as gingival recession can significantly compromise the esthetic outcome, especially when multiple anterior maxillary teeth are involved [7,8]. Over the years, several surgical procedures have been proposed to manage these complex cases, including coronally repositioned flaps, lateral sliding flaps, free gingival grafts, and subepithelial connective tissue grafts using tunneling and envelope flap techniques [7][8][9][10][11][12]. These procedures aim to establish a harmonious gingival architecture, increase the amount of keratinized gingiva, and reduce hypersensitivity related to denuded root surfaces [13]. However, to achieve satisfactory results, precise surgical techniques must be employed and attention to detail is necessary to prevent the formation of post-surgical defects, such as scarring, keloid-like defects, and loss of the interdental papilla [7,9]. Data have shown that the outcomes of the surgical treatment of gingival recession are positive. A recent Cochrane systematic review evaluating root coverage procedures for single and multiple recession has reviewed 48 randomized controlled trials in which gingival recessions were addressed with subepithelial connective tissue grafts plus coronally advanced flap and tissue guided regeneration with resorbable membranes plus connective tissue grafts and it concluded that all procedures can be successfully provided for treating single or multiple gingival recessions [14].
Ceramic dental laminate veneers are a well-documented and predictable treatment for modifying the shade of whitening-resistant teeth, improving the shape of teeth with acquired malformations and loss of facial enamel, correcting minor rotations, and closing moderate diastemas [15][16][17][18]. Contemporary dental ceramic systems have improved mechanical and optical properties [19][20][21]. When ceramic restorations are conditioned and combined with resin-based cement, a strong and long-lasting chemical, the micromechanical bond can be created between the ceramic and the underlying tooth substrate [22,23]. Despite significant advances in adhesive dentistry, the success of treatment with dental veneers depends on several factors, including thorough planning, adequate preparation and conditioning of the tooth structure, satisfactory design and conditioning of the restorations, and preparation of the receptor dental and gingival tissues to ensure the harmonious integration of the restorations with the rest of the mouth [24,25]. This clinical report presents the interdisciplinary management of a patient with esthetic complaints related to asymmetric anterior gingival architecture and severely discolored and eroded maxillary anterior teeth. The patient was treated with a combination of minimally invasive ceramic laminate veneers and plastic mucogingival surgery.

After a medical questionary, the patient was classified as an ASA type 1 patient systematically healthy with no medical conditions to be concerned about prior to dental care. Additionally, he expressed suffering from severe root sensitivity when drinking or eating. At the initial consultation, the patient expressed that he used to chew on citrus fruits with his anterior teeth and that lemon juice was a big part of his diet until he noticed defects in his anterior teeth. Intraorally, generalized loss of clinical attachment and Miller type 1 gingival recession was observed in the maxillary right first premolar, right canine, and both maxillary central teeth. Additionally, cervical non-carious lesions were noticed on teeth maxillary right first premolar, right canine, right lateral, right central, and maxillary left central, and significant loss of facial enamel was noticed on both maxillary central teeth, giving the teeth a lower color value than the adjacent anterior teeth (Figure 2A  After a medical questionary, the patient was classified as an ASA type 1 patient sys tematically healthy with no medical conditions to be concerned about prior to dental care Additionally, he expressed suffering from severe root sensitivity when drinking or eating At the initial consultation, the patient expressed that he used to chew on citrus fruits wit his anterior teeth and that lemon juice was a big part of his diet until he noticed defects i his anterior teeth.

Discussion
An attractive smile plays a significant role in contemporary society [1], and with the advances in dental material science and CAD-CAM technologies, highly esthetic ceramic restorations [26][27][28] can now be designed and manufactured consistently and predictably [18]. To achieve satisfactory results, gingival esthetics must be established to provide a pleasing "frame" for dental restorations [1]. Successful plastic surgery periodontal procedures have been used to correct deficiencies related to gingival recession [11,13]. Connective tissue grafts have been reported to provide satisfactory root surface coverage, ranging from 76.6% to 100%, depending on the size and configuration of the recession, the location, and the number of teeth treated [7,9]. Research suggests that connective tissue grafts and tunneling techniques offer advantages over other periodontal procedures, such as coronally and horizontally repositioned flaps, as the forces exerted by intraoral muscle insertions can be circumvented [7] and the integrity of fragile interproximal tissues can be preserved [9]. Moreover, this treatment modality permits predictably enhancing the amount of keratinized tissue available, thus creating a more maintainable periodontal environment [8]. Both elements are crucial to ensure the satisfactory esthetic integration of restorations with equigingival or subgingival finish lines [14]. Previous case reports treating multiple recessions in the esthetic zone have shown positive outcomes. Case series treating 22 patients with a total of 73 recessions with a mean depth of 2.8 mm were treated with the coronally advanced flap technique and reevaluated at 1 year, resulting in an average of 97% root surface coverage, and a complete root coverage was achieved in 16 out of the 22 patients [29]. Patients were treated with a similar approach in another case series with a longer follow-up treating 22 patients with 73 gingival recessions in the esthetic zone Miller Class I and II [30]. The results displayed 94% of root coverage at 5 years of examination and complete coverage was obtained in 15 out of the 22 patients [30]. Moreover, a systematic review from the American Academy of Periodontology (AAP) evaluated the success of soft tissue root coverage procedures. This review evaluated 234 clinical trials on class I, II III, and IV gingival recessions, and it demonstrated that all clinical procedures provided a significant reduction in recession depth, concluding that connective tissue grafts provide the best outcome for clinical practice [31]. Due to the positive clinical reports, soft tissue grafting procedures can be considered in the anterior region to fulfill the patient's esthetic demands.
Traditionally, root surfaces are cleaned with compounds such as citric acid or tetracycline hydrochloride preceding root coverage procedures to remove the smear layer, open the dentinal tubules, and decrease the microbial load and bacterial cytotoxic byproducts [7][8][9]. In the present clinical report, 24% EDTA gel (Straumann PrefGel; Straumann, Basel, Switzerland) was applied for 2 min before the connective tissue graft application. Ethylenediaminetetraacetic acid is an organic compound widely used in endodontics as an adjuvant irrigation agent due to its effectiveness in removing calcium by means of chelation [18]. Highly concentrated gel preparations of this compound are advantageous since their viscosity permits the selective treatment of the intended surfaces only, thus avoiding the highly concentrated formulation's unnecessary demineralization of other dental tissues and substances. Some studies have recommended the results obtained with EDTA gel. A clinical trial evaluating EDTA gel conditioning during periodontitis assessed the surface topography and periodontal ligament cell adhesion with and without the application of EDTA gel, and the results concluded that it provides the most desirable root surface to which maximum periodontal ligament cells can adhere and on which they can grow [32].
Ceramic restorations are a well-supported treatment that can improve the patient's self-esteem and social interactions [1,14]. Modern dental ceramics possess mechanical and chemical properties, making them excellent restorative materials. Feldspathic and glassinfiltrated ceramics can be bonded to the enamel using an adhesive hybrid layer [18] and have a modulus of elasticity similar to the enamel, making them a suitable "biomimetic" alternative to replace lost enamel [14]. In the present clinical report, the teeth were minimally prepared using the desired restorative contours established with a diagnostic wax-up as a reference. This step was critical to ensure that the tooth preparations preserved as much enamel as possible to guarantee adequate union between the restoration and the substrate, and to provide enough space to fabricate esthetic and structurally durable restorations.
Further studies with larger sample sizes and longer follow-up periods are needed to confirm the effectiveness of the connective tissue grafting technique in combination with EDTA gel for root surface cleaning. Additionally, it would be valuable to compare the outcomes of this technique with other periodontal procedures to determine the most effective and efficient treatment for gingival recession.
