Influence of implant design and length on stress distribution in immediately loaded implants in posterior maxilla - A two-dimensional finite element analysis.

Aim: The aim of this two dimensional (2D) finite element analysis study was to evaluate the influence of implant design (step and tapered) and length on stress distribution at bone implant interface, when placed in maxillary posterior bone under immediate loading protocol.

Materials And Methods: 2D finite element models were developed to simulate the two types of implant designs, i.e.

Investigating the impact of diameters and thread designs on the Biomechanics of short implants placed in D4 bone: a 3D finite element analysis.

Background: Dental implants emerge as a dependable and efficacious alternative for patients experiencing partial or complete tooth loss. The stability of these implants is influenced by surface topography and macro-level design. In cases where the height of the maxillary posterior region is diminished, employing short implants can prove advantageous.

Three-Dimensional FEA Analysis of the Stress Distribution on Titanium and Graphene Frameworks Supported by 3 or 6-Implant Models.

Titanium is the main component of dental implants. It is also routinely used as a framework material for implant-supported full-arch prostheses due to its low density, biocompatibility, and other mechanical properties. Remarkable mechanical properties such as lesser mass density and higher young's modulus of graphene have gained popularity among scientists, improving the properties of biomedical implants.

Changes in cellular and molecular components of peripheral blood in patients with generalized aggressive periodontitis.

Aim: The association between periodontitis and systemic health is evident; however, until recently, there has been a lack of scientific evidence to define the relationship between aggressive periodontitis and systemic conditions. The aim of the present study was to evaluate the changes in the white blood cell count and levels of serum proteins in patients with generalized aggressive periodontitis (GAP) and to compare it with periodontally-healthy controls.

Methods: Patients with GAP (n = 60) and periodontally-healthy controls (n = 60) were recruited.

Lip repositioning.

Excessive gingival display is a frequent finding that can occur because of various intraoral or extraoral etiologies. This report describes the use of surgical lip repositioning technique for the management of a gummy smile associated with vertical maxillary excess and hypermobility of the upper lip. The procedure restricts the muscle pull of the elevator lip muscles by shortening the vestibule, thus reducing the gingival display when smiling.

3D finite element analysis of immediate loading of single wide versus double implants for replacing mandibular molar.

Purpose: The purpose of this finite element study was to compare the stresses, strains, and displacements of double versus single implant in immediate loading for replacing mandibular molar.

Materials And Methods: Two 3D FEM (finite element method) models were made to simulate implant designs. The first model used 5-mm-wide diameter implant to support a single molar crown.

2D FEA of evaluation of micromovements and stresses at bone-implant interface in immediately loaded tapered implants in the posterior maxilla.

Aim: The aim of the study is to evaluate the influence implant length on stress distribution at bone implant interface in single immediately loaded implants when placed in D4 bone quality.

Materials And Methods: A 2-dimensional finite element models were developed to simulate two types of implant designs, standard 3.75 mm-diameter tapered body implants of 6 and 10 mm lengths.

An in-office, cost effective technique for measuring width of bone using intra-oral periapical radiographs in occlusal projection.

Background: The aim of this in vitro study was to determine the dimensions of ridge/width of bone and deviation of center of ridge using Intra Oral Periapical Radiographs (IOPA) in occlusal projection as a preprosthetic diagnostic method.

Materials And Methods: Mandibles with edentulous space were procured and cold cure acrylic stents were fabricated. Three holes were drilled occlusally, buccally, lingually and filled with gutta percha.

Short implants: A systematic review.

Background: Short implants are manufactured for use in atrophic regions of the jaws. Although many studies report on short implants as ≤10 mm length with considerable success, the literature regarding survival rate of ≤7 mm is sparse.

Purpose: The purpose of this study was to systematically evaluate the publications concerning short dental implants defined as an implant with a length of ≤7 mm placed in the maxilla or in the mandible.

Evaluation of Micromovements and Stresses around Single Wide-Diameter and Double Implants for Replacing Mandibular Molar: A Three-Dimensional FEA.

Purpose. The purpose of this finite element study was to compare stresses, strains, and displacements of double versus single implant, in immediate loading for replacing mandibular molar. Materials and Methods.
