Added Sugar and Oral Health: A Position Paper of the Brazilian Academy of Dentistry.

Excessive sugar consumption is the main cause of dental caries. Dental caries is highly prevalent and negatively impacts the quality of life at all stages. Furthermore, sugar consumption is associated with other noncommunicable conditions and diseases, such as obesity, diabetes, and cardiovascular diseases.

Prosthetically Driven Alveolar Reconstructions: A Retrospective Study.

This study aims to evaluate the post-extraction alveolar bone reconstruction amongst 12 patients exhibiting loss of buccal bone plate in a tooth of the anterior region of the maxilla using the prosthetically-driven alveolar reconstruction technique (PDAR). In PDAR, a partial fixed provisional prosthesis (PFPP [conventional or adhesive]) with a specially designed pontic maintains the clot in a mechanically stable position during alveolar regeneration. Moreover, the pontic design, in hourglass shape and located in the subgingival area, also prevents gingival margins from collapsing.

Evaluation of Pink and White Esthetic Scores for Immediately Placed and Provisionally Restored Implants in the Anterior Maxilla.

Purpose: To evaluate the esthetic result of immediately placed implants with immediate provisional restorations in the anterior maxilla using the pink esthetic score (PES) and white esthetic score (WES).

Materials And Methods: The records of patients were evaluated retrospectively. The evaluation was carried out by two examiners using 12 evaluation criteria.

Comparative analysis of microorganism species succession on three implant surfaces with different roughness: an in vivo study.

Purpose: Because almost all implant systems reveal marginal bone loss and some implants can be affected by periimplantitis, to realize an effective maintenance treatment it is important to understand the biofilm development over different implant surfaces. The objective of this human study is to comparatively analyze the kinetics of microorganism species succession on 3 surfaces.

Materials And Methods: Three commercially pure titanium sheets with different roughness were randomly fixed bilaterally on the lingual regions of Hawley-type plates of 6 volunteers.

Osseointegration of titanium alloy and HA-coated implants in healthy and ovariectomized animals: a histomorphometric study.

Objectives: The objective of the present study is to evaluate the response to dental implants in healthy and osteoporotic bone.

Materials And Methods: Ten ovariectomized (OVX) New Zealand rabbits submitted to a hypocalcic diet and 10 sham-aged rabbits were used. All animals were submitted to bone mineral density (BMD) measurements before ovariectomy, and also 4 months afterwards, using dual energy X-ray absorptiometry.

Surface characterization of dental implants coated with hydroxyapatite by plasma spray and biomimetic process.

Purpose: The aim of this study was to characterize implants coated with hydroxyapatite (HA) using 2 different processes.

Materials And Methods: Commercially pure titanium implants were coated with HA using a modified biomimetic process and the plasma spray process. These implants were characterized by scanning electron microscopy, Fourier-transformed infrared spectroscopy, and x-ray photoelectron spectroscopy.

Histomorphometric analysis of HA-coated implants interface with irradiated and nonirradiated bone.

Purpose: The purpose of the present study was to investigate whether osseointegration of HA-coated implants can be affected by irradiation.

Materials And Methods: A single dose of 15 Gy was applied to the right tibia of 5 rabbits and the left tibia was not irradiated and used as control. After 3 months, the animals were killed and the quantification of the implant-bone contact surfaces was performed using scanning electron micrographs of the resin sections containing the implants in the irradiated and nonirradiated bones.

Tridimensional analysis of maxillary sinus anatomy related to sinus lift procedure.

Purpose: To evaluate the angulation of the maxillary sinus walls at the apical sinus region.

Materials And Methods: Using preoperative computerized tomographies of 15 patients selected for sinus lift procedures, the angulation of the maxillary sinus floor was measured drawing straight lines tangential to the mesial and lateral walls. The measurements were taken from sagittal images at specific areas (i.

Achieving aesthetic success with an immediate-function implant and customized abutment and coping.

Unlabelled: The absence of teeth in the anterior region often results in a number of negative consequences compromising appearance and facial anatomy, as well as patients' self-esteem and social behavior. Dental implants have increasingly become a viable option for achieving natural-looking restorations. The success of anterior restorations, however, depends upon several factors.

Single-tooth implants in the maxillary incisor region with immediate provisionalization: 2-year prospective study.

Osseointegrated implants have been increasingly used for aesthetic, predictable restorative treatment. This study presents the 2-year postoperative results of patients treated with immediate, single, tapered implants in the maxillary incisor region and the simultaneous placement of provisional implant-supported crowns. Of the total of 92 implants placed, 6 were lost.
