Expanding soft tissue with Osmed tissue expanders in the goat maxilla.

Objectives: soft tissue limitations are encountered in implant dentistry, due to the loss of alveolar bone. The aim of this study is to compare the outcome of soft tissue preparation using Osmed self-inflating soft tissue expanders with different in situ times in two implantation techniques.

Material And Methods: Osmed self-inflating soft tissue expanders were implanted in goats using a tunnel approach and a flap approach.

Digital videographic measurement of tooth display and lip position in smiling and speech: reliability and clinical application.

Introduction: Tooth display and lip position in smiling and speech are important esthetic aspects in orthodontics and dentofacial surgery. The spontaneous smile and speech are considered valuable diagnostic criteria in addition to the posed social smile. A method was developed to measure tooth display in both smile types and speech.

The oral pigmentation chart: a clinical adjunct for oral pigmentation in removable prostheses.

Purpose: Non-Caucasian patients exhibit different characteristics of oral pigmentation and may request that the acrylic resin parts of their dentures look natural, simulating the original mucosal color. Tooth loss, bone resorption, and lack of attached gingiva may, however, make it difficult to determine what the original pigmentation was like. The purpose of this investigation was to study the distribution in oral pigmentation around the natural dentition in non-Caucasians, in a preliminary effort to classify these variations into a chart of oral pigmentation, and to analyze its reproducibility.

Shear bond strength of different types of luting cements to an aluminum oxide-reinforced glass ceramic core material.

Objective: The aim of this study was to find the optimal choice of luting cement to Synthoceram, an aluminum oxide-reinforced glass ceramic material. The bond strength of five different commercial luting cements to the ceramic material was evaluated. The effect of surface treatments, etching, sandblasting, silanizing, and combinations of these treatments was also investigated.

Microbiological and clinical effects of chlorhexidine enclosed in fixtures of 3I-Titamed implants.

This double-blind study used a split-mouth design to investigate the microbiological and clinical effects of 0.2% chlorhexidine enclosed in fixtures. Twelve patients had 46 fixtures implanted.

Effect of GBR and fixture installation on gingiva and bone levels at adjacent teeth.

Guided bone regeneration (GBR) is frequently used in oral implantology. It is unclear to what extent GBR affects the periodontium of adjacent teeth. Therefore, the present study quantifies changes in the proximal gingiva and bone levels at these teeth in 30 patients.

Porcelain-veneered computer-generated partial crowns.

Objective: It would be advantageous to be able to use computer-aided design and manufacturing to fabricate a restoration that can be layered with a conventional porcelain veneer in the occlusal region, thus optimizing esthetics, function, and strength. This case study reports the laboratory technique and the clinical performance of 38 partial crowns fabricated with computer technology and veneered with porcelain.

Method And Materials: Twenty-one mandibular and 17 maxillary molars in 27 patients were prepared for partial crowns.
