The clinical and histological features of the peripheral odontogenic fibroma are briefly outlined. A case arising from the attached lingual gingiva between the mandibular right permanent first molar and the second molar in a 67 year old Indian female is reported here. The unusual occurrence of marked clear cell differentiation within the odontogenic epithelial component, and histogenetic link to the clear cell rests of the dental lamina and surface epithelium are discussed.
In the first part of this article the biological rationale and the use of different implants was considered. In this second part, guided bone regeneration (GTR) around implants, immediate placement of implants, peri-implantitis, and failing implants will be discussed.
Dental implantology is a rapidly advancing area of dentistry providing a number of alternative treatment possibilities for patients with partially or fully edentulous mouths. The following article is the first in a series of three dealing with various aspects of dental implantology, with a particular emphasis on those areas related to field of periodontology. In this paper we shall consider the biological basis of dental implants, different implant systems, and the peri-implant sulcus. Forthcoming articles will cover the diagnosis and treatment of peri-implantitis and failing implants, guided bone regeneration around implants, immediate implant placement, the placement of implants in the posterior maxillae, and implant maintenance.
