Accuracy of Implant Placement Position Using Nondental Open-Source Software: An In Vitro Study.

Purpose: To evaluate the accuracy of implant placement position using two different dental implant planning software.

Materials And Methods: A set of Digital Imaging and Communications in Medicine (DICOM) files from a cone beam computed tomography of a patient missing maxillary right first premolar was used. Implant planning was done using two open-source programs: A nondental 3D Slicer/Blender (3DSB) software and a commercial dental implant treatment planning program: Blue Sky Plan 4 (BSP4).

Virginia-based periodontists' perceptions: Current and future trends of the specialty.

Background: The aim of this survey was threefold: (1) describe the demographics of periodontists and their practices in Virginia; (2) explore periodontists' perceptions of the impact that changes in the field of dentistry (i.e. increasing corporate dentistry, graduate debt, digitalization, and volume of periodontal procedures done by general practitioners [GPs]) are having on the specialty; (3) explore how periodontists might adjust their practices to account for these trends.

Dental patients' self-reported use of dietary supplements on medical history questionnaires.

Dietary supplement effects and drug interactions can lead to significant adverse health events, thus potentially impacting the safe delivery of oral healthcare. This study sought to determine the frequency of, and factors impacting, dietary supplement use among 209 dental patients and whether the design of a medical history questionnaire influences reporting of supplement use. Patients were randomly allocated to 1 of 2 groups in which they completed either a standard medical history questionnaire (n = 107) or the same questionnaire with an additional item about dietary supplement use (n = 102).

The effect of esthetic crown lengthening on perceptions of a patient's attractiveness, friendliness, trustworthiness, intelligence, and self-confidence.

Background: Smile esthetics have been shown to play a major role in the perception of whether a person is attractive, and whether they are perceived as friendly, trustworthy, intelligent, and self-confident. A proposed major determinant of the esthetics of a smile is the amount of gingival display, which can be excessive in cases of altered passive eruption. The aim of this study is to see whether altering the amount of gingival display of patients would affect dental professionals' and laypersons' perceptions of the aforementioned social parameters.

Randomized, prospective, clinical evaluation of prosthodontic modalities for mandibular implant overdenture treatment.

Statement Of Problem: Mandibular implant overdentures provide improved treatment outcome than conventional denture therapy, but there is controversy as to which overdenture treatment is the best choice.

Purpose: This study evaluated 3 different mandibular implant overdenture treatments with respect to prosthesis retention and stability, tissue response, patient satisfaction and preference, and complications to determine treatment outcomes.

Material And Methods: In a prospective, randomized clinical trial, using a crossover design, 30 subjects (mean age, 58.

Clinical crown length of the maxillary anterior teeth preorthodontics and postorthodontics.

Background: Prevalence information on excessive gingival display in postorthodontic patients is limited. By studying the size relationship of the clinical crowns of teeth, in an orthodontic population, we can begin to quantify their need for periodontal plastic surgery.

Methods: Preorthodontic and postorthodontic crown dimensions were measured on 200 plaster models, and after 5 years, 31 of the subjects were recalled to repeat the measurements in a clinical examination.

Surgical crown lengthening: evaluation of the biological width.

Background: Previous surgical crown lengthening studies have investigated positional changes of the free gingival margin but not the biological width. Histological studies utilizing animal models have shown that postoperative crestal resorption allowed reestablishment of the biological width. However, very little work has been done in humans.
