Biologic and Esthetic Outcome of CAD/CAM Custom Ceramic Implant Abutment: A Clinical Report.

A prerequisite of a functional and esthetical implant-supported crown is a proper surgical planning and an abutment with a design and color that maintain the initial soft-tissue contour. This clinical report describes the use of a custom ceramic implant abutment designed with computer-aided design and computer-aided manufacturing (CAD/CAM) technology. A zirconia framework was milled and cemented extra orally to a prefabricated titanium base, the new custom abutment being both precise and esthetic.

Prosthodontic management of an extreme atrophy of the mandible correlated with a prominent genial tubercle - a clinical report.

Extreme atrophy of the mandibular alveolar crest can pose a great prosthodontic challenge, especially when the genial tubercles remain as a bony projection in the floor of the mouth. This article is a clinical report on the prosthodontic management of a severe mandible atrophy correlated with a prominent genial tubercle. A complete denture was carefully designed and fabricated in order to restore both the function and esthetics of the patient.

Cone beam computed tomography observations of the lingual foramina and their bony canals in the median region of the mandible.

Purpose: To investigate by means of CBCT the presence of lingual foramina and their bony canals in the midline of the mandible and to describe their anatomical characteristics.

Materials And Methods: CBCT examinations of 36 patients were carefully examined in the median region of the mandible in order to detect the lingual foramina and their corresponding vascular canals. Their presence, number, position, diameter and trajectory were established.

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

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.

Phenotypic and molecular methods used for identification of oral streptococci and related microorganisms.

The oral cavity contains the greatest biodiversity, over 70 species being isolated from mouth mucosa, saliva, denture surfaces and/or dental-plaque. The oral streptococci, representing over 80% of the mouth micro flora, are able to synthesize glucosyl-transferases, enzymes involved in glucans production. Glucans are involved in production of an extracellular slime layer promoting adhesion and formation of a dental plaque biofilm.

A simple prosthetic restorative solution of a single peg-shaped upper central primary incisor in a case of ectodermal dysplasia.

Introduction: This clinical report describes the oral rehabilitation of a 7-year-old male diagnosed with hypohidrotic ectodermal dysplasia and anodontia.

Background: Ectodermal dysplasia (ED) comprises a large, heterogeneous group of inherited disorders, which are defined by primary defects in the development of two or more tissues derived from the embryonic ectoderm (skin, hair follicles, nails, teeth, sebaceous and sweat glands). Our patient exhibited the typical general and cranio-facial features of ED as well as emotional and behavioral problems.

Correct complete denture rehabilitation, a chance for recovering abused tissues.

The prosthodontic treatment must provide for the edentulous patients bio-functional prosthetic restorations, bio-prophylactic for the surrounding tissues. In this aim, an edentulous patient must be submitted to a methodical clinical examination in order to establish the quality of hard and soft tissues, which will indicate the degree of difficulty of the prosthetic treatment. Additional investigation as a microbiologic examination and cephalometric radiographs can be useful in a modern investigation.

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 success depends on establishing a correct and long lasting relation between them. The present article's purpose is to present the pro-prosthetic and prosthetic treatment possibilities for partial or complete edentulous patients who have variations of the mucosa of the residual ridges, as well as to present the histopathological importance of these variations.
