Conventional tooth implants lacks the damping prosperities of the periodontal ligaments (PDL) compound. It may therefore, disrupts the natural function of implant and leads to excessive stress and strain in jaw bone. Our new proposed implant has the viscoelastic properties needed to overcome such difficulties. A three dimensional finite element model of modified implant was developed and was subjected...
Oral implantology is the branch of dentistry focused on the reconstruction of missing teeth and their supporting structures with natural or synthetic substitutes. Conventional instruments used during oral implantation exhibit severe operational limitations, especially in the presence of limited surgical access, anatomically delicate bone structures, and proximity to soft tissues, because of the high...
The localized management of sinus floor (LMSF) is one of key technologies in dental implant surgery, but the lining mucosa of maxillary sinus is easily impaled during LMSF surgery. This paper proposed a computer aided design method to construct 3-D finite element model of LMSF. Then the models are processed for analysis. Finally, the virtual surgery simulation was carried out from three aspects which...
A new kind of sensor for measuring force in arbitrary direction to test force's value and direction with a dimension Oslash53 mm times h8.2 mm, developed for dental surgery measurement, has been proposed in this article. A four-beam structure is employed for arbitrary force test. Based on material theory the value and direction of force can be calculated by strain test. A matrix that proves the four-beam...
This paper introduces the production of 3D virtual clinic to help dentists in their treatment. To achieve this goal, different scientific areas are integrated such as: computer graphics, pattern recognition, computer vision, information technology and finite element machine (FEM). The proposed system includes the following tools; patient information system, automatic 2-D cephalometrics, 3-D cephalometrics,...
