Regeneration, Reconstruction & Restoration (Triple R)

Trauma to the face usually involves nose and perinasal structures due to anatomic position. Treating injuries caused by trauma to these structures is hard for maxillofacial surgeon, especially if secondary rhinoplasty is being considered. In this article, after a short introduction to anatomy and diagnosis process, secondary rhinoplasty is discussed. A total of 13 articles is used for available articles between 1967 to 2014.

Klipple-Trenaunay syndrome (KTS) is characterized by three symptoms including hemangioma, varicose veins and hypertrophy of bony and soft tissues. Hypertrophy usually appears unilaterally, and mostly involves lower limb, however, trunk, upper limb, and face may also be affected. The occurrence of orofacial manifestations in KTS is rare. In this article a case with hemifacial hypertrophy as a rare manifestation of KTS who underwent surgery based on patient demand of aesthetic has been presented. Further, presentations of KTS in head and neck region and considerations for corrective surgery of these patients have been discussed.

Allogeneic bone graft has been suggested to be a quite propitious alternative bone substitute to autograft. However, controlled clinical trials with adequate samples, including meticulous bone gain measurements, histological evaluations, and long-term clinical and radiographic assessments of inserted dental implants have not yet been conducted to evaluate the abovementioned assumption. This case report presents a patient for whom allogeneic bone block grafting with a guided bone regeneration procedure had been performed in order to improve the horizontal dimension of atrophic maxillary edentulous ridge. Following an uneventful 8-month healing period, though not obvious clinically, tomography images revealed a great amount of resorption, suggesting the replacement of bone graft with soft tissue. Histologic evaluation revealed no evidence of active bone formation. A mass of connective fibrous tissue was infiltrated with inflammatory cells. In between, the presence of trabecular bony structures with a distribution of empty lacunae was illustrative of graft remnants.

Introduction: Zeolite is an aluminosilicate biomaterial which has been used widely in medicine, tissue engineering, drug delivery systems, wound dressing, as an antibacterial agent and also it has been taken into consideration in dental sciences. So the aim of this study is reviewing the application of this amazing substance in dental sciences.

Materials and Methods: In recent years there are many investigations on application of Zeolite. This review has been done on the application of this agent in dentistry. According to investigations from 1980, zeolites applications in dentistry were classified to the application in tissue engineering, root canal therapy, prosthodontics, periodontics and implant, restorative dentistry and oral medicine.

Results: zeolite is a porous, biocompatible and antibacterial agent and according to its suitable properties it has been used as tissue engineering scaffold, wound dressing and so on. Zeolite is an antibacterial agent that can be used in root canal disinfection and in soft liner dentures. It can inhibit pathogens of dental caries and periodontal disease. According to biocompatibility of Zeolite, it also can be used as implant coating to improve osteointegration. It has also been used to detect squamous cell carcinoma.

Conclusion: It seems that Zeolite can be considered as an amazing substance in dental sciences.
