Abstract
There are various causes for residual alveolar ridge defects, most common being the collapse of the cortical plate during extraction. Localized defects of alveolar ridge affect prosthetic restoration due to poor emergence profile of the pontic. Various soft tissue augmentation procedures have been recommended for the correction of these defects. Abrams’s roll technique has been widely used for soft tissue ridge augmentation in the maxillary anterior region where aesthetics is a prime concern. The original Abrams’s roll technique has been modified and revisited by many authors to overcome the limitations. The present clinical case report discusses the modified roll technique as an option to treat alveolar ridge deformity. The current procedure resulted in expectable ridge augmentation, uneventful healing, and good aesthetic outcome. Hence this modified technique can be selected for the treatment of mild to moderate Seibert class I ridge defects in the aesthetic zone.
Highlights
Localized alveolar ridge defect is common after prolonged edentulism
Esthetic outcome of fixed prosthesis depends on three-dimensional emergence profile of the pontic which is highly dependent on harmony between soft tissue and prosthesis
When the fixed partial denture is planned as an option for rehabilitation, in the majority of cases acceptable aesthetic outcome can be achieved by soft tissue correction alone.[10]
Summary
Localized alveolar ridge defect is common after prolonged edentulism. These defects may be caused by the deficiency in the volume of bone and soft tissue resulting from extractions, advanced periodontitis, and periapical pathologies.[1]. To avoid exposure of palatal bone, modified roll technique was altered using trap-door technique.[8] The epithelium over the palatal connective tissue is raised and preserved to cover the palatal bone in this technique This technique is recommended for augmentation of moderate defects like Seibert’s Class I. The present case report demonstrate modified rolled palatal pedicle connective tissue graft combined with immediate temporization of the area to correct the localized maxillary anterior alveolar ridge defects and to get an emergence profile for the pontic. A 28-year-old, systemically healthy female patient visited the outpatient department of Periodontology and Implantology, presenting Seibert class I deformity in the edentulous ridge following extraction of the maxillary left lateral incisor few years before (Figure 1) This region only requires soft tissue augmentation to correct the ridge. In the present case report single incision was adopted for obtaining connective tissue pedicle, which presents several advantages: i) It requires
