Horizontal bone augmentation of the maxillary and mandibular alveolar ridges has been conventionally performed using mini titanium alloy screws. The titanium alloy screws are used to fixate corticocancellous block grafts to the recipient site or for tenting the mucoperiosteum to retain particulate bone grafts. Nonresorbable guided tissue regenerative membranes reinforced with titanium have also...

alveolar ridge is underdeveloped in ectodermal dysplasia (ed). the available treatment plans include fixed, removable or implant-supported prostheses, alone or in combination. a 5 year-old boy was referred for treatment to the department of prosthodontics, tehran university of medical sciences with the chief complaint of missing teeth. prosthodontic treatment was performed to improve masticatio...

Ridge splitting and ridge expansion have been used to expand narrow alveolar ridges. Piezosurgical ridge splitting involves separating the atrophic crests with piezosurgical inserts. Ridge expansion with motor-driven expanders was proposed to achieve the cortical dilation. The purpose of this study was to evaluate the efficacy of ridge gain by ridge expansion or ridge splitting. Eighteen (36 ra...

Despite being considered noncritical size defects, extraction sockets often require the use of bone grafts or bone graft substitutes in order to facilitate a stable implant site with an aesthetically pleasing mucosal architecture and prosthetic reconstruction. In the present study, the effect of novel TiO(2) scaffolds on dimensional ridge preservation was evaluated following their placement int...

Non-Hodgkin's lymphomas are a group of highly diverse malignancies and have a strong tendency to affect organs and tissues that do not ordinarily contain lymphoid cells. Primary extra nodal lymphoma of the hard palate is rare. Here, we present a case of diffuse large B cell lymphoma in a 60-year-old male patient that manifested as slightly painful ulcerated growth on the edentulous right maxill...

Edentulous alveolar ridges always demonstrate atrophy when left alone without dental treatment, making rehabilitaion of masticatory function in this atrophic ridge in need of auxilliary augmentation procedures. This is always challenging in posterior maxil‐ lary edentulous area because local anatomical condition of this region is easily ham‐ pered as masticatory force in the posterior dentition...

Orthodontic closure of old, edentulous spaces in the mandibular posterior region is a major challenge. In this report, we describe a method of orthodontic closure of edentulous spaces in the mandibular posterior region accelerated by piezoelectric decortication and alveolar ridge expansion. Combined piezosurgical and orthodontic treatments were used to close 14- and 15-mm-wide spaces in the man...

s: In case extensive atropy of the alveolar process of the mandible may result in the mental foramen becoming located on or near the crest of the residual ridge. This frequently is the cause of discomfort for the denture wearers. When adjustment of the denture does not alleviate the problem, it may be necessary to transpose the nerve and this is also indicated when the alveolar sulcus is to be ...

This report describes the proliferation and the expression of Cbfa-1 in a rare case of peripheral osteo-chondroma arising from the mandibular oral mucosa of an edentulous alveolar ridge. Histologically, the lesion consisted of mesenchymal cells with either bone or cartilage tissue in the center. Almost all the tumor cells were reactive for PCNA, however, only the cells around the bone and carti...

Congenital epulis (CE) of the newborn is a rare benign soft tissue tumor that presents at birth. It occurs usually as a single mass with various sizes, although some multiple lesions have also been reported. The lesion is more common in female neonates and normally affects the maxillary alveolar ridge. Rare recurrence and no malignant alteration have also been reported. This condition may inter...
