The patients suffering from various maxillary defects of palate and lips require a form of definitive treatment after attaining adulthood. These defects affect the patients psychologically giving them negative impact of life, the treatment of these defects with definitive prosthesis will enhance the aesthetics along with occlusal rehabilitation and giving them the confidence they require. This case report describes the rehabilitation of 18yrs old female patient with unilateral cleft palatal defect which is rehabilitated with porcelain fused to metal (PFM) crowns covering the defect and as well providing the confidence the patient required.
Keywords: Occlusal rehabilitation, esthetic, unilateral cleft palate, porcelain fused to metal (PFM)

| Introduction:|| |
Clefts of the lip and palate (CLP) are commonly encountered congenital anomalies, affecting one in seven hundred live births and often result in severe functional deficiency on the patient's chewing abilities, appearance and ability to speak. The restorative dental care and management of cleft lip and palate patients calls for a complex multi-disciplinary approach with long term involvement. These patients eventually require definitive fixed or removable prosthesis for aesthetic and functional demands when they become adults. The maxillary central incisors are often hypoplastic with short roots and are severely malposed. When planning a prosthetic rehabilitation for a patient with congenital abnormalities; lack of teeth, intraoral anatomic deformities, inadequate arch development, and inspection of appropriate occlusal vertical dimension must be taken into consideration. Paranaiba et al demonstrated that patients with unilateral CLP were frequently more affected by dental anomalies than bilateral CLP. The incidence of congenitally missing teeth, especially lateral incisors adjacent to the alveolar cleft is high., There are various treatment modalities of definitive prosthesis for unilateral and bilateral cleft lip and palate patients after completion of orthodontic treatment such as; conventional multi-unit fixed partial denture (FPD), resin composite veneered multi-unit FPD, fiber- reinforced composite resin-bonded FPD, conventional removable partial denture (RPD), RPD with extra coronal attachment and combination of fixed and removable partial dentures. In this case report the management of an alveolar cleft which is being managed by PFM crowns to maintain the esthetics desired by the patient due to economical constraints.
| Case Report:|| |
An 18 years old female patient reported to outdoor patient department of Department of Prosthodontics in Vananchal Dental College and Hospital, Garhwa, Jharkhand for the replacement of missing teeth (22) due to the alveolar cleft. On clinical and radiographic (OPG & OCCLUSAL x-ray) [Figure 1] examination confirmed that a repaired unilateral cleft palate and moderate tissue deficiency in the palate. Bone grafting and implant placement were not indicated due to the extent of the defect area in the palate [Figure 2]a, [Figure 3]. There were no food or liquid leakage into the nasal cavity but the extent of hard and soft tissue deficiency influences the aesthetic appearance and phonetics. A Porcelain Fused to metal fixed partial denture was chosen as a definitive restoration since this system has an acceptable marginal fit, adequate function and good esthetic properties. The diagnostic casts were made and a mock preparation followed by wax up was done, the esthetic results were evaluated and patient consent was obtained with the results obtained in mock up. The abutment teeth chosen were both central incisor, right lateral incisor, both canines, and both first premolars. The mesially tilted right central incisor [Figure 2]b was root canal treated as the patient was not willing for orthodontic correction of the tooth. After preparation of these teeth [Figure 3] a pre fabricated tray and two types (light and heavy body) silicone impression material (soft putty, light body) was used. The master cast was transferred to an articulator using an interocclusal record when the molars were in the maximal intercuspal position. We had to use one extra pontic (except the left incisor pontic) to restore the defect area between upper left lateral incisor and canine. The pontic was designed in a modified ridge lap pattern. The pontic was contoured like an upper right canine for the best aesthetic results [Figure 4]. The fittng accuracy of the frameworks was tested in the patient's mouth before the ceramic veneer was applied. The frameworks were evaluated intraorally for accuracy of fit after the addition of veneering ceramic. The gingival margins of the right canine pontic and lateral incisor abutment were not at the same level with the other abutment. To restore the osseous defect gingival porcelain was used to replicate the gingiva. As the gingival margins were not visible in the smile line, the defect on the alveolar ridge was restored by extending the length of the canine pontic, with gingival porcelain. The completed prosthesis was luted with Type I Glass ionomer cement [Figure 5]. The defect area on the alveolar ridge was healthy and aesthetically compatible with the restorations.
| Discussion:|| |
Adolescent patients with cleft lip and palate present special prosthodontic problems and demand particular attention to aesthetic considerations. Management of such patients should, ideally, begin early and be part of the overall team approach and patient must be instructed to maintain good oral hygiene and dietary advice being given to patients at the outset, and thereafter continually reinforced. Numerous factors affect decisions for the most appropriate restoration. Henry and Tan addressed issues of patient psychology, particularly the age at which patients are receiving prosthetic care. Siebert classified the ridge defects into three categories.
Class I- Loss of faciolingual ridge width with normal apicocoronal height.
Class II- Loss of ridge height with normal width.
Class III- Loss of both ridge width and height.
Authors described the use of multiple unit bridges (6-10 units) to replace missing teeth and stabilize the maxillary arch., This patient had a wide space between left central incisor and canine because of the alveolar defect. Therefore, one more canine pontic was placed to restore this area. The crown for the left canine abutment was fabricated like an upper first premolar to maintain symmetry. During the provisional phase, aesthetics, phonetics, retention and occlusion were assessed. As the gingival margins were not visible in the smile line, the length of the canine was extended with gingival porcelain for the final prosthesis. Thus, the defect on the alveolar ridge could also be restored and the gingival margin of the left canine pontic was at the same level with the other abutment teeth.
Herein, Prosthodontic should make a decision whether to use fixed (conventional or implant supported) or removable partial denture. The circumstances of vertical bone loss at edentulous anterior region, RPDs can hinder severe hygiene problems and deficiencies of labial support contrary to FPDs and can provide good esthetics. In addition it is possible to ensure permanent retention of maxillary arch while hindering arch collapse with RPDs. Despite these advantages, patient satisfaction with RPDs significantly reduces with age. The common objection is that its removable structure accentuates its artificial character. Alternatively osseointegrated implants after secondary bone grafting have provided an invasive treatment approach for cleft lip and palate patients., The use of endosseous implants for CLP patients with grafted alveolar clefts have lots of advantages, especially preservation of tooth structure in healthy adjacent teeth and the prevention of resorption of grafted bone. Secondary bone grafting at the early stage of the mixed dentition posses many benefits, however there is a conflict on timing of bone grafting. Despite various advantages of surgical intervention in cleft lips and palates, conventional prosthetic rehabilitation may be preferred especially in young patients, in whom bone grafting followed by endosseous implants is not a treatment option, because of patients choice or socio-economic constraints.
| Conclusion:|| |
Despite, the recent advancement in bone grafting and dental implants for cleft lip and palates, conventional prosthodontic rehabilitation, remains to be an important aspect in treatment of such patients. The treatment plan markedly improved the masticatory, speech functions and also helped to stabilize the psychological state of the patient.
