Dental implant is very important part in the field of dentistry. The production of dental implant helped to provide the dentist to planning it, placing into jaw bone and to restoring of missing teeth whenever it fails. An abutment is a part of dental implant which is used to fix over the implant part and below the crown. The crown is made by porcelain material which is used to be attached directly on the implant part. An abutment part which is used to fixed in implant to make dental implant strong and to improve the stability into jawbone. The dental abutment provides the retention into the implant, to support, to improve the stability and for the increase the final restoration in jawbone where it is fixed. Key Words: Dental Implant, Abutment, Stress, Crown. 1. Introduction Teeth loss is a common problem in day to day life so for that the dental implant process is used. There are uses of dental implants on missing teeth is also a common thing to replace the real teeth. There are so many researches are done on dental implant designs to make proper and well- shaped. Its material is biomaterial which is convenient for body and the variations in technique of the implantation has increased more. In the field of dentistry many of work included related to the dental implant. Use of proper shape and sizes in design of dental implant, biomaterials which helps to avoid infection and surface modification is very essential to improve the durability of the dental implant. In the dental implant there are various types of dimensions that are presently used for various types of bone quality. In dental implant, different types of abutments such as angular and straight are also presents. 2. Design of Dental Implant In the dental implant, there are various types of sizes and shapes are available. These are helps to dental implants to fit in jawbone easily. There are changes in shapes and sizes of implant, types of threads, and its thickness is stated. There are number of design and sizes of abutment, crown are available. Proper size, shape of dental implant and quality of bone improve stability of dental implant in the jaw bone. There are parts which present in dental implant are given further. 1)Length:- When forces act on dental implant the stress distribution is depends on its length and its diameter in the jawbone which is surrounded to implant. There are some lengths of dental implants which are increases from 6mm to 20mm. 2)Diameter:- In the sizes of diameter of dental implant there are many of variability available. Diameter is important factor for the stability and retention of implant when it fixed into jawbone. When point related range is concern then diameter from 3mm to 7mm are used. If the dental implants diameter is wide then it helps to improve the stability. There are variations available for different type of bone quality. 3)Geometry:- Dental implant has a many types of geometry such as cylindrical type of dental implant, conical type of shape and screw shape hollow cylindrical shape is also present. Some related studies are shows or focus on the conical implant surfaces that it occurs higher type of stresses as compared to use of screw shaped of geometry of dental implant. 4)Thread:- In lower position of dental implant, threads are important part to fix into jawbone. It improves stability in jaw bone. Threads are also help to minimizing or reduce the stresses in the bone and implant when forced. In threads classification, the depth pitch thread, thread as flank angulation, some with the top radius of curvature and also the straight part present at the position of bottom side of the thread in implant. 3. CAD models of Dental Implant All attachment in dental implant parts are made or generated with the help of Pro/E software. Crown, abutment, implant, bone and gums are made in the Pro/E software to make complete dental implant. Some images of three dimensional modeling are shown below. Fig -1: Abutment
