The treatment choice for the recovery of missing teeth has been expanded for two patients and clinicians with the utilization of dental implants. For the success of dental implants, the quality and the amount of the available bone and soft tissues in the recipient site are very important factors. However, because of the tumor, injury, periodontal ailment, and so on, these variables might be undermined or inaccessible which again brings out the need for extra hard and soft tissue manipulation. This paper outlines a technique using a modified rolled palatal pedicle connective tissue graft with an autogenous bone graft from the mandibular symphysis area to achieve a predictable long-term success of dental implants prosthesis.

   Introduction Top

Substitution of missing maxillary front tooth with lingering edge imperfection is a test and hard assignment to accomplish. Esthetics outcome relies upon three-dimensional emergence profiles of the prosthesis, tooth shape, and shade of fixed prosthesis. The emergence profile is reliant on remaining alveolar ridge volume, width, and length. A careful treatment planning is obligatory for the accomplishment of the objective of an anticipated esthetic outcome for anterior ridge defects.[1]

Tooth loss along with it brings inescapable sequelae of quick resorption of the alveolar bone because of the absence of intraosseous incitement by periodontal ligament (PDL) fibers and renders to the deficient amount of bone, following tooth loss.[2]

Tooth loss in the anterior maxilla causes early bone resorption, however, essentially in the horizontal direction, and mostly loss of bone occurs on the buccal side (Att et al., 2009).[3] There is a high incidence (91%) of residual ridge remodeling after anterior tooth loss. Most of these are class III deformities (Siebert's characterization).[4]

As reported in the literature, implant treatment is a productive, profitable, and predictable choice for the restoration of missing teeth.[5] Along with teeth, the strength of delicate soft tissue around implants is an important factor to accomplish an acceptable esthetic outcome.[6]

A nutritive undersupply of the bone may happen because of deficient peri-implant tissues bringing about fixture loss because of resorption. Appropriate gingival architecture is particularly significant so as to accomplish attractive anterior esthetics.[7] For augmentation of defects, bone can be harvested from nonessential bones, such as from iliac crest, mandibular symphysis (chin area), and anterior mandibular ramus (coronoid process).[2]

The present case report demonstrates a technique using a modified rolled palatal pedicle connective tissue graft, with an autogenous bone graft from mandibular symphysis area to correct the localized maxillary anterior alveolar ridge defects while replacing an anterior missing tooth using implant therapy.

   Case Report Top

A systemically healthy patient aged 20 years reported to the department of prosthodontics with the chief complaint of a missing tooth and a discolored tooth in the maxillary anterior region. On clinical examination, it was found that the patient had a congenitally missing maxillary right central incisor. The patient was motivated to replace his congenitally missing maxillary right central incisor via orthodontic and prosthodontic treatment. However, due to financial constraints, patients insisted on replacement of clinically missing maxillary right lateral incisor only. Intraoral and radiographic examination revealed a severe alveolar ridge deformity in relation to missing maxillary right lateral incisor region [Figure 1]a and a root canal-treated maxillary left central incisor. Cone-beam computed tomography scan [Figure 1]b of the maxillary anterior region showed thin remaining bone (Siebert's class III defect), and clinical examination showed thin gingival biotype (>1.5) with a narrow band of attached gingiva. The region needs to be augmented through hard and soft tissue augmentation.

Among all the options, the patient opted for autologous bone grafting followed by implant placement for the missing tooth and PFM crown for the central incisor, and informed consent was obtained from the patient.

After administration of local anesthesia, incisions are made and mucoperiosteal flap was raised to expose the surgical site. An acrylic surgical stent was placed in the patient's mouth for easy access. The implant site preparation was completed at a depth of 10.5 mm [Figure 1]c.

A narrow platform implant with a diameter of 3 mm and a length of 10 mm is inserted. Final insertion was done using a torque ratchet with an insertion torque of 30 Ncm [Figure 1]d.

In the attached gingiva, a midline vertical release incision [Figure 2]a was performed to get access to the donor site extending from distal sides of both the canines. Particulate bone graft material was taken from mandibular symphysis region [Figure 2]b and compacted on the defect site [Figure 2]c. The site was covered with a biodegradable membrane.

A partial-thickness horizontal incision [Figure 2]d was made on the palatal aspect of the ridge from central incisor to canine. From the horizontal incision line, an oblique incision was placed from mesial line angle of right canine to second premolar [Figure 3]a. Underlying connective tissue was exposed. Parallel incision was given from the mesial line angle of the central incisor. These parallel incisions were joined by a horizontal incision at the apical end. A full-thickness palatal connective tissue pedicle graft approximately two times more than the apicocoronal length of the ridge defect was rolled onto the defect site. Horizontal mattress sutures were placed on the donor and defect site [Figure 3]b and [Figure 3]c. A prefabricated Essex appliance made of vacuum-formed sheet and artificial lateral incisor [Figure 3]d was inserted in the patient's mouth.

Three-month postoperative evaluation showed a considerable amount of ridge thickness with soft tissue emergence profile [Figure 4]a, with no postoperative complications which have been assessed with a periapical radiograph [Figure 4]b. A second-stage surgery was performed after 6 months for exposure of the permucosal element and placement of a healing abutment to recontour the emergence profile [Figure 4]c. After 10 days, a provisional crown [Figure 4]d was given. The adjacent root canal-treated central incisor was prepared for porcelain fused to metal crown, and simultaneously, the titanium abutment was milled and adjusted for the lateral incisor [Figure 5]a. Impression was obtained from an open tray method [Figure 5]b. After metal coping trial [Figure 5]c, final prosthesis was delivered with desirable esthetics and accurate fit [Figure 5]d.

   Discussion Top

Dental implants are the treatment of choice for the restoration of missing teeth these days. However, the placement of an implant in the alveolar bone stays a difficult factor for the vast majority of the clinicians because of resorption of the alveolar ridge bringing about an absence of bone volume.[1]

The placement of esthetic implants is motivated by both the theory of restoration and biology. To place the implant esthetically, it should fulfill the criteria of contour so that the restoration is gratifying. It should be positioned biologically to allow both hard and soft tissue architecture to be preserved. In the current case report, implant was placed 3–4 mm apical to the gingival margin of the contra lateral tooth to enable a natural emergence profile of restoration. Mesiodistal placement was also considered by maintaining a space of 1.5–2 mm with the adjacent tooth.[8]

Different soft and hard tissue manipulation strategies were suggested for the management of alveolar deformities. Methodology for hard tissue improvement includes autologous block grafts, bone grafts, and substitutes[5] and guided bone regeneration.[9] To achieve an adequate emergence profile, it is necessary to have an ample amount of bone and soft tissue thickness, especially on the buccal side.

Techniques for soft tissue profile improvement include onlay free mucosal graft interpositional connective tissue grafts, pouch graft, roll pedicle grafts, and modified roll pedicle grafts.[1] In the current trend, these roll grafts are a viable treatment alternative to achieve a desirable soft tissue contour. The advantage of using palatal pedicle connective tissue is due to its intact blood supply which reduces the risk of graft necrosis and provides proper bulk of soft tissue.[1]

For appropriate esthetic result, deficient alveolar bone height and width regularly require bone manipulation procedures performed either previously, at the time of, or after the implant surgical procedure.[10] The best quality level of bone grafting materials is autografts. These are taken from a same patient, acquired from one site and placed in another site, and regenerate the bone by the procedure of osteogenesis and osteoinduction. Using xenografts could elicit acute and chronic immune reactions, as well as disease transmission due to interaction of residual proteins within graft particles and the host cell receptors.[10] The comfort of autograft bone material is that the bone structures, for example, minerals, collagen, and viable osteoblasts, and bone morphogenic proteins, are kept up. It is osteoinductive, biocompatible, simple to control, and effortlessly profited from remote destinations. When compared to other alternatives, transplants of autogenous origin have a shorter healing and incorporation period. The symphysis region had been selected for harvesting in this clinical situation to cover the defect due to the presence of denser bone. Placement of healing cap over the implant helps augment the gingiva, resulting in excellent emergence profile, gingival, and papilla contour.

In this new combined surgical and prosthetic approach for correcting soft tissue dehiscence and hard tissue defect, there is also a placement of short clinical crown, so it should not induce any stress on the underlying healing soft tissue. However, within 2–3 months of healing, all the marginal gingival tissue and mesial and distal papilla grip the provisional crown, resulting in a proper emergence profile. It also ensures the increase vascular supply and allows the tissue to occupy the proximal space adjacent to the definitive prostheses.
