Dental implants are divided into 5 groups based on their functions as follows: Intramucosal Inserts: Button implants are inserted on removable dentures surface and on the side, they are inserted within the oral mucosa. Then, by inserting the denture in its place; they play the role of stabilizing it on patient’s jaw. These implants have been used for fixing complete dentures in upper jaw but using them is not common these days.
What are dental implant types and their functions?
Dental implants are divided into 5 groups based on their functions as follows:
Button implants are inserted on removable dentures surface and on the side, they are inserted within the oral mucosa. Then, by inserting the denture in its place; they play the role of stabilizing it on patient’s jaw. These implants have been used for fixing complete dentures in upper jaw but using them is not common these days.
These implants have a ladder like structure to be compatible with alveolar bone in jaws. They are designed to stabilize prosthesis especially when the lower jaw atrophy is severe. These implants are manufactured and prepared in a 2-stage surgery. In the first stage, periosteal mucosa texture is pushed aside from the bone surface. Then, molding is performed to have a shape for producing sub-periosteal implants.
In the second stage, this structure is inserted under the mucosa texture during a surgery. Prosthesis is inserted on the bases of this structure that are located outside of the mucosa texture. Nowadays, it is possible to have the shape of patient’s jaw by computerized tomographic techniques so that there is no need to perform the surgery of first stage. In this way, the implant is inserted into the jaw just be one surgery.
These implants are inserted in lower jaw anterior area. The screws will pass the width of the jaw completely. These implants are used when mandible bone atrophy is very severe. It will stabilize the denture in lower jaw.
These implants are inserted in to the mandible bone by two kinds of surgery: inside or outside of the oral cavity. Despite of relative considerable success of this technique; this is hardly used due to complicated and difficult procedure of inserting them in the jaw bone.
These implants are inserted within the jaw bone and prosthesis will be produced after stabilizing the implant in the jaw bone. Nowadays, Endosseous Implants are used more than the other types of implants.
These pin implants are used when the tooth is periodontally and the proportion of crown to root is not suitable. For this type of implant, it is necessary to clean and prepare the canal of the root.
After preparing the end of root, it is necessary to use a reamer to remove a part of the root. Then, the area will be filled with a sealer and the implant is inserted into the canal of the root. It should be fastened with screws in its place.
Implant implants are a kind of rehabilitation and restoration of the health of the teeth because they have to consider chewing, speaking and grooming of the teeth, and adding to the beauty of the teeth and face can be done by restoring and restoring the teeth and implanting implants. .
Scientific Principles for the Design of Dental Implants in Relation to Types of Force and Its Application to the Patient (Part II)
The body of the cylindrical tooth implant concentrates the shear force on the surface of the implant-readable contrast. The scan also connects to the cylindrical implant during the initial repair. To tolerate these forces by implants, the implant body should be replaced by a microscopic grip, such as Roughenig or coating coatings such as titanium spray plasma, acidic, mechanical hydrochloric acid or hydroxyacetamide HA, so that the implant can withstand the initial forces.
What is a dental implant?
An implant is a piece of metal that is often in the form of a root of the tooth and placed inside the patient's jaw bone. A dental implant is used as the basis for inserting a denture (dentures), and restoring the crown of the missing teeth using this implant base is possible.
A dental implant is a pure titanium metal metal used as a root tooth with the purpose of preserving the coatings that replace the crown of the tooth. After the implant is tightened in the jaw bone, a new tooth is installed on it, which completely resembles the natural teeth and gives the patient a completely natural sense
Scientific Principles in the Design of Dental Implants in Relation to Types of Force and Its Application to the Patient (1)
The task of dental implants is to transfer forces to surrounding biological tissues, such as bones and gums. The guidance and control of biomechanics is dependent on two factors:
1 - Characteristic of the force input
2 - Functional level (functional) where the force is propagated.
This control and guidance of the forces are directly related to the principles of designing the initial function of the implants and the degree of modulation of the implant-dependent prosthesis. Accordingly, the performance of the forces and their characteristics and the bone-implantation-implant surface where the force is distributed is more than 90 Implant design available. The biomechanical basis of different implant designs is evaluated based on their ability to control biomechanical forces. The fundamental principles of force (F) and level (S) are combined
