Clinical and histoenzymatic interrelations of the edentulous ridge's mucosa.

چکیده
The edentulous ridge's mucosa presents various histological aspects and different histoenzymatic equipment. These aspects are determined by constitutional factors (genetic, nutritional), as well as by age and by the associated pathology. The purpose of this paper is to evidentiate, through histochemical techniques, the aerobe (NADH2-cytochrome-c reductase) and anaerobe (lactatdehydrogenase) oxidoreducing enzymatic activities, as well as the hydrolytic enzyme's activity (ATP-ases, pH 9.4), corroborated with the histological aspects of the edentulous ridge's mucosa. The enzymatic activity and the morphological alterations present various aspects, depending on the metabolic type (aerobe oxidative, anaerobe oxidative, hydrolytic), according to the mucosal area (epithelium, chorion), to the different cell types, or even within the same cellular type (especially at the level of the connective lamina propria cells). They also vary from one edentulous patient to another, depending on the existence of a previous prosthetic treatment and on the type of this treatment. The local clinical examination, sustained by a histoenzymatic investigation, reveals the importance of the structural alterations and they can offer guidance for the proper prosthetic treatment and for the achievement of functional prosthetic restorations that provide the oral mucosa its necessary trophicity for as long as possible.

Clinical, histological and therapeutic study regarding the variations of the edentulous ridge's mucosa.
The oral mucosa of the edentulous ridges presents many morphological macroscopic and microscopic variations, from one area of the edentulous ridge to another, as well as from one patient to another. Because the mobile prosthetic treatment realizes a direct contact between the dental prosthesis and the mucosa of the denture supporting structures and of the peripheral structures, the prosthetic s...
متن کاملComparison of the Efficacy of Digital Caliper and a Newly Designed Digital Bone Gauge for Measurement of Edentulous Alveolar Ridge Width
Objectives: An efficient, safe, affordable and easily accessible measuring instrument for quantitative assessment of bone prior to dental implant placement enables more accurate treatment planning. Costly imaging modalities are neither widely available, nor affordable for some patients. This study sought to assess the efficacy of a newly designed digital bone gauge for measurement of bone width...
متن کاملProsthetic management of edentulous mandible using endosseous implants and overdentures.
UNLABELLED The choice of a suitable prosthesis for a specific case is determined to a great extent by the underlying residual bone as well as the mucosa. Also of significance are the expectations and demands of the patient from the prosthesis. The following case report discusses the rehabilitation of a complete edentulous mandibular arch with an implant retained mandibular over denture. CLINI...
