Radiographic assessment of findings in the maxillary sinus using cone-beam computed tomography.

OBJECTIVES. To assess the presence of anatomic variations and pathology of the maxillary sinus using cone beam computed tomography (CBCT) of the maxilla where pre- implant surgery is planned. MATERIAL AND METHODS.

Does residual cement around implant-supported restorations cause peri-implant disease? A retrospective case analysis.

Objectives: The purpose of this study was to determine the relationship between patients with a history of periodontitis and development of cement-related peri-implant disease.

Materials And Methods: Seventy-seven patients with 129 implants for this retrospective analysis were selected from completed implant cases that were scheduled for regular maintenance or had experienced mechanical or biological complications between years 2006 and 2011 in private practice. Implants with extracoronal residual cement and implants without cement remnants were analyzed.

Passive tactile sensibility of teeth and osseointegrated dental implants in the maxilla.

Purpose: The purpose of this study was to compare passive tactile sensibility of natural teeth and osseointegrated dental implants in the maxilla.

Material And Methods: Twenty-nine patients (17 males and 12 females) were included in the study. Natural teeth were subdivided into two groups: non endodontically treated teeth (NETT) and endodontically treated teeth (ETT).

Influence of thin mucosal tissues on crestal bone stability around implants with platform switching: a 1-year pilot study.

Purpose: The aim of this pilot study was to determine what effect thin mucosal tissues can have on crestal bone stability around implants with platform switching.

Materials And Methods: Twelve 2-piece implants, consisting of 6 implants with horizontally matching implant-abutment connection (control) and 6 implants with platform switching (test) were placed in 4 patients. The mean age of the patients was 43 years (range, 37 to 56 yrs).

Reaction of crestal bone around implants depending on mucosal tissue thickness. A 1-year prospective clinical study.

Purpose: The aim of this paper was to distinguish what kind of mucosal tissue, measured at the top of the crest can be referred to as thin, medium or thick and its influence on crestal bone loss around dental implants after a 1-year follow-up.

Materials And Methods: Totally 64 implants were evaluated in 26 patients. 32 implants (test group) were placed about 2 mm supracrestally and 32 implants (control group) were positioned equal to the bone level.

The influence of soft tissue thickness on crestal bone changes around implants: a 1-year prospective controlled clinical trial.

Purpose: The aim of this clinical trial was to evaluate the influence of gingival tissue thickness on crestal bone loss around dental implants after a 1-year follow-up.

Materials And Methods: Forty-six implants (23 test and 23 control) were placed in 19 patients. The test implants were placed about 2 mm supracrestally, whereas the control implants were positioned at the bone level.

Influence of ceramic inlays and composite fillings on fracture resistance of premolars in vitro.

Objective: The aim of this study was to assess the resistance of fracture of mesio-occlusal-distal (MOD) ceramic inlays and composite fillings in premolars and to compare fracture modes between the groups.

Material And Methods: Twenty seven extracted intact human premolars were selected and divided into three groups: I - intact teeth (control group), II - MOD cavities restored with indirect ceramic inlays (Finesse, Dentsply Ceramco, USA), III - MOD cavities restored with direct composite fillings (Filtek P60, 3M ESPE, USA). The fracture resistance (N) was assessed under axial compressive loading with a metal cylinder 3.

Influence of abutment material on stability of peri-implant tissues: a systematic review.

Purpose: The aim of this systematic review was to evaluate available evidence for a difference in the stability of peri-implant tissues between titanium abutments versus gold alloy, zirconium oxide, or aluminum oxide abutments.

Materials And Methods: Studies were identified by examining several electronic databases and major dental implant, prosthetic, and periodontal journals. To be selected for the preliminary article pool, the article must have been written in the English language and published from 1980 to March 2007.

Biologic width around implants. An evidence-based review.

Purpose: The concept of biologic width forms a basis for successful peri-implant soft tissue integration around titanium implants. Therefore, the objectives of this review are to determine and critically evaluate the present knowledge about biologic width around implants and to establish future research trends.

Materials And Methods: The literature was selected through several electronic databases, as well as a manual search in the major dental implant, prosthetic and periodontal journals.

Changes in the periodontal condition after replacement of swaged crowns by metal.

Evidence based clinical studies have shown exact recommended design for artificial crown reconstruction with acceptable long-term results taking into an account the biological price. Previous histological and clinical studies proved that fixed prostheses might influence the periodontal condition of crowned teeth, if not all biological criteria have been considered. The aim of the present study was to assess the periodontal condition of the crowned teeth after stainless steel swaged crowns were replaced by cast metal ceramic crowns.

The effect of 2 different diameter cast posts on tooth root fracture resistance in vitro.

Prosthetic treatment frequently involves the restoration of endodontically treated teeth (ETT), which in turn implies that there has been a reduction of the crown due to previous restorative treatment, trauma and/or endodontic manipulations. The prognosis of a restored ETT is very much dependent on pre-endodontic status of the tooth, the quality of the endodontic treatment, the amount remaining tooth structure and the bone support. The aim of this study is to measure fracture resistance of extracted premolar teeth restored with 2 different diameter posts.
