Interdisciplinary rehabilitation of a patient with ectodermal dysplasia utilizing digital tools: A clinical report.

The present clinical report describes the rehabilitation of a patient diagnosed with ectodermal dysplasia performed by an interdisciplinary team in a comprehensive approach aided by digital technology. The complexity of the treatment was related to predictability regarding timing and the type of approach. The patient was referred for treatment because of congenitally missing and abnormally shaped permanent teeth.

Evaluating the delay prior to primary care presentation in patients with lung cancer: a cohort study.

Background: Little is known about 'within-patient delay', which is the time from first symptom of lung cancer to contacting primary care.

Aim: Primary outcomes were length of within-patient delay and the proportion of total delay it represents. Secondary outcomes were factors causing delay and survival.

Narrow-diameter implants in the anterior region: A meta-analysis.

Purpose: Implants in the anterior region are challenging, and literature reporting outcomes of narrow-diameter implants (NDIs) in anterior sites is scarce. This systematic review summarized evidence of functional and esthetic performance of anterior single crowns supported by NDIs.

Materials And Methods: Ten databases were searched to find studies evaluating anterior single crowns supported by NDIs.

The influence of restorative procedures on esthetic outcomes in implant dentistry: a systematic review.

Purpose: The objectives of this review were to (1) identify if prosthodontic parameters influence the esthetic outcome of implant-supported restorations and (2) make clinically relevant recommendations based upon the findings.

Materials And Methods: Electronic and manual searches of dental literature were performed to collect information on esthetic outcomes based on objective criteria. The prosthodontic parameters included optimal three-dimensional implant position, the utilization of provisional restorations, the timing of provisional restoration with regard to implant placement, the choice of prosthodontic platform size and form, the abutment and definitive restoration material, and the mode of prosthesis retention.

Use of prefabricated titanium abutments and customized anatomic lithium disilicate structures for cement-retained implant restorations in the esthetic zone.

This report describes the fabrication of customized abutments consisting of prefabricated 2-piece titanium abutments and customized anatomic lithium disilicate structures for cement-retained implant restorations in the esthetic zone. The heat-pressed lithium disilicate provides esthetic customized anatomic structures and crowns independently of the computer-aided design and computer-aided manufacturing process.

Clinical and radiologic outcomes after submerged and transmucosal implant placement with two-piece implants in the anterior maxilla and mandible: 3-year results of a randomized controlled clinical trial.

Purpose: The aim of this investigation was to evaluate the 3-year outcomes regarding crestal bone level, clinical parameters, and patient satisfaction, following submerged and transmucosal implant placement for two-piece implants in the anterior maxilla and mandible.

Materials And Methods: Patients requiring dental implants for single-tooth replacement in the anterior maxilla or mandible were enrolled in a randomized, controlled, multicenter clinical trial. The implants were randomized at placement to either submerged or transmucosal healing, with final restorations placed after 6 months.

Submerged and transmucosal healing yield the same clinical outcomes with two-piece implants in the anterior maxilla and mandible: interim 1-year results of a randomized, controlled clinical trial.

Objectives: To test whether or not transmucosal healing at two-piece implants is as successful as submerged placement regarding crestal bone levels and patient satisfaction.

Material And Methods: Adults requiring implants in the anterior maxilla or mandible in regions 21-25, 11-15, 31-35 or 41-45 (WHO) were recruited for this randomized, controlled multi-center clinical trial of a 5-year duration. Randomization was performed at implantation allowing for either submerged or transmucosal healing.

Early loading after 21 days of healing of nonsubmerged titanium implants with a chemically modified sandblasted and acid-etched surface: two-year results of a prospective two-center study.

Purpose: The aim of this two-center study was to evaluate screw-type titanium implants with a chemically modified, sandblasted and acid-etched surface when placed in the posterior maxilla or mandible, and loaded 21 days after placement.

Material And Methods: All 56 patients met strict inclusion criteria and provided informed consent. Each patient displayed either a single-tooth gap, an extended edentulous space, or a distal extension situation in the posterior mandible or maxilla.

Single-stage Straumann dental implants in the aesthetic zone: considerations and treatment procedures.

The aim of this paper was to identify factors significant to the use of single-stage dental implants in the aesthetic zone and discuss treatment considerations related to them. In view of available literature and clinical experiences, treatment outcomes associated with the use of single-stage Straumann implants (Institut Straumann AG, Waldenburg, Switzerland) in the aesethetic zone can be considered positive and predictable.

Energies of 1 (≥3) Configurations in Hei as Calculated from Polarization Theory.

The calculated singlet-triplet mean energies are given for all He i configurations having 3 ≤ ≤ - 1 from 4 to 8. Since only Stark-shifted transitions have been observed for such configurations with ≥ 4, the calculated positions are the most accurate available. The polarization energy (to the quadrupole approximation) for two-electron ions may be evaluated for higher or from the simple formulas.

New Vacuum Ultraviolet Wavelengths and Revised Energy Levels in the Second Spectrum of Zinc (Zn ii).

Spectra from sliding spark discharges between zinc electrodes and from a hollow-cathode source were photographed in the range 2105-1400 Å with the NBS 10.7 m vacuum spectrograph. New measurements of 130 Zn ii lines in this region, combined in some cases with previous measurements in the air region, were used to derive revised positions for the known levels.

Calculations of Znii 3d45 and Agi 4d56, and Some New Levels in these Spectra.

Results of intermediate-coupling calculations are given for Zn ii 3 45 and Ag i 4 56. A [(4 ) , (56) ] coupling scheme is appropriate for the latter. New 3 4(D)5 D and 3 4(D)5 D levels were found in Zn ii, and a few other additions and revisions are given for the analysis.

The Spectrum of Singly Ionized Atomic Iodine (I ii).

The I ii spectrum has been excited in electrodeless lamps and photographed from 655 A to 11084 A. Wavelengths and estimated intensities are given for almost 2,400 lines. A revision and extension of the earlier analyses of this spectrum has increased the number of known even levels from 43 to 124, and the number of odd levels from 55 to 190.

Energy Levels and SpectSSrum of Neutral Helium (He I).

A table of energy levels based on the most accurate observations now available is given for the neutral He atom. The wavelengths contained in a revised list of He I lines from 320 A to 21132 A are also based on the best measurements, over half of them having been calculated from the wavenumber separations of appropriate levels. Several previously disturbing features of the He term scheme are obviated by the revised level values.
