Clinical performance of non-precious metal double crowns with friction pins in severely reduced dentitions.

Objectives: Several in vitro studies have investigated the retention of double crowns with friction pins (DCP); however, clinical data on their long-term success have not been reported. We sought to evaluate the 5-year survival rate of DCPs in patients with severely reduced dentition (SRD) and not severely reduced dentition (NSRD).

Materials And Methods: A total of 158 patients were treated with 182 dentures on 520 abutment teeth between 2006 and 2016.

Complications of endodontically treated abutment teeth after restoration with non-precious metal double crowns.

Objectives: This study aimed to evaluate the effects of endodontic treatment on the complication rate in abutment teeth following double crown treatment.

Materials And Methods: Data of 233 patients supplied with 278 prostheses on 773 teeth were retrospectively analyzed. The 60-month cumulative complication rate for vital, root filled, and post and core reconstructed abutment teeth is calculated using the Kaplan-Meier method.

Minimal invasive microscopic tooth preparation in esthetic restoration: a specialist consensus.

By removing a part of the structure, the tooth preparation provides restorative space, bonding surface, and finish line for various restorations on abutment. Preparation technique plays critical role in achieving the optimal result of tooth preparation. With successful application of microscope in endodontics for >30 years, there is a full expectation of microscopic dentistry.

Parotid gland-recovery after radiotherapy in the head and neck region--36 months follow-up of a prospective clinical study.

Background: The aim of the present study was to evaluate the recovery potential of the parotid glands after using either 3D-conformal-radiotherapy (3D-CRT) or intensity-modulated radiotherapy (IMRT) by sparing one single parotid gland.

Methods: Between 06/2002 and 10/2008, 117 patients with head and neck cancer were included in this prospective, non-randomised clinical study. All patients were treated with curative intent.

Prospective observation of CAD/CAM titanium-ceramic-fixed partial dentures: 3-year follow-up.

Purpose: There is lack of knowledge about the clinical performance of computer-aided design/computer-aided manufacturing (CAD/CAM) titanium-ceramic-fixed partial dentures (FPDs). The purpose of this study was to evaluate CAD/CAM titanium-ceramic FPDs after 3 years in function.

Materials And Methods: Thirty-one FPDs were fabricated for 23 patients.

Influence of sterilization on the retention properties of magnetic attachments for dental implants.

Objectives: When used with dental implants advantages of the magnetic attachments include control of load transmitted to implants, improvements in stability, support and retention for the prosthesis, and the relative ease of prostheses fabrication. Clinically, the use of sterilized components is required, and this may be problematic as magnetic alloys are sensitive to temperature. The purpose of this study was to evaluate the influence of autoclave sterilization on the maximum retentive forces and characteristic curves for magnetic attachments recommended for use with dental implants.

Corrosion of dental magnet attachments for removable prostheses on teeth and implants.

Purpose: For a long time, the use of magnets for the anchorage of dental prostheses failed due to lack of biocompatibility and the magnets' high susceptibility to corrosion in the mouth. These facts make encapsulation of the magnetic alloy with a corrosion-resistant, tight, and functionally firm sealing necessary. Due to different products and analysis methods, it is not feasible to compare the findings for contemporary products with the sparse and rather old test results in the literature.

Marginal accuracy of combined tooth-implant-supported fixed dental prostheses after in vitro stress simulation.

Objectives: Caries, periodontal disease, and peri-implant inflammation caused by deficient marginal adaptation of fixed prostheses are reasons for clinical failure of combined tooth-implant-supported fixed dental prostheses (TISFDP). This in vitro study examined the marginal accuracy in TISFDP after simulated stress in an artificial oral environment.

Materials And Methods: Twelve three-unit TISFDPs were fabricated using a high noble alloy on models containing a human premolar with an artificial periodontium and an implant.

Mechanical properties of magnetic attachments for removable prostheses on teeth and implants.

Purpose: Magnetic attachments on teeth and implants may be used to improve stability, support, and retention of removable prostheses. Various forms of magnetic attachments are available, divided according to the design, the mechanical properties of the attachments, and the clinical indication. Recently developed attachment systems are small and promise improved retentive capacity, while existing magnetic attachments continue to be technologically modified and improved.

Meta-analysis of treatment need for temporomandibular disorders in adult nonpatients.

Aims: To determine the prevalence of treatment need for temporomandibular disorders in adult populations by meta-analysis of nonpatient studies and to investigate factors influencing temporomandibular disorder treatment-need estimates.

Methods: Population-based and nonpatient studies of adult subjects with temporomandibular disorders published in the English language prior to July 2006 were systematically reviewed. Electronic databases (MEDLINE, CINAHL, and Science Citation Index Expanded) were searched (n = 641).

Incisal tooth wear and self-reported TMD pain in children and adolescents.

Purpose: Incisal tooth wear may be a sign of long-term bruxing behavior. Bruxism is purported to be a risk factor for temporomandibular disorders (TMD). The aim of this population-based cross-sectional study was to determine if anterior tooth wear is associated with the self-report of TMD pain in children and adolescents.
