The objective of project is to reduce the micromotion of novel implant under the static loads using function of uniform design for FE analysis. Integrating the features of regular implant, a new implant model has been done. Micromotion of the novel implant was obtained using static structural FE analysis. Compared to the existing International team for implantology implants, the micromotion of the novel implant model was considerably decreased by static structural analysis. Six control factors were taken for achieving minimizes the micromotion of novel dental implant system. In the present work, uniform design technique was used to create a set of finite element analysis simulation: according to the uniform design method, all FE analysis simulation; compared to the original model, the micromotion is 0.01944mm and micromotion of improved design version is 0.01244mm. The improvement rate for the micromotion is 35.02%.

Nowadays, the implant system can easily and immediately replace missing teeth or damaged teeth. Dental implants act like teeth or become permanent parts of the human mandible. Immediate loading of the dental implant system has newly gained fame due to several factors including pain, healing time, aesthetic appearance, and psychological benefits to the patient. The biological process between implants and bone is called osseointegration. The primary stability is the main role of the successive surgical process. Achieving primary stability is an important factor for successful osseointegration, such as bone quality, design of the implant, and surgical methods.

Researchers consider primary stability a requirement of successful osseointegration(Branemark, 1977). Bone quality, implant shape, and surgical technique influence the primary stability of dental implants. Implant design is the relevant parameter for gaining primary stability (Chong, Khocht, Suzuki, & Gaughan, 2009). The taper implant model provides better primary stability, and it has shown better stability through the healing process(O'Sullivan, Sennerby, & Meredith, 2004). X. Li and Dong (2017) investigated the influence of various neck designs on implant stress distribution. In this study, the researcher investigated the adult mandible with various implant neck structures and different loading conditions. Researchers indicated that various neck morphologies with v-shaped micro threads of implant influence the stress circulation around the implant-bone surfaces. Moreover, researchers observed the overall stress at the cortical bone area and around the implant neck. Researchers examined the FE analysis and investigated the load distribution of various thread profiles and material properties of the dental implant around the mandibular bone. Several researchers investigated Zirconium dental implants and observed in their study that they have high mean stress at their implant bodies and low mean stress around their bones compared to TI implants,(Shafi, Kadir, Sulaiman, Kasim, & Kassim, 2013).
