ABSTRACT
Dental implants are made from one or more biomaterials, with titanium and alloys being the most commonly used biomaterials as they exhibit good biocompatibility, mechanical properties and machinability. Osseointegration as defined by Branemark and the closure of soft tissue is the foundation for the success of dental implants. Improving the success rate of dental implants, reducing treatment time, helping with rapid loading and reducing the incidence of peri-implantitis and peri-implant mucositis remains an important area of research in the field of oral implantology. Increasing numbers of studies have focused on altering the surface of titanium and titanium alloy in order to increase their biological activity and facilitate osseointegration and soft tissue healing. To achieve these objectives, various conventional methods exist to alter the surface of titanium, but many revolutionary approaches were implemented with the advent in nanotechnology to efficiently modify the surface. However, with the advent of nanotechnology, an innovative technology called Self Assembly is introduced for surface modification. It is done by imprinting the monolayers on the surface of the biomaterials (titanium or its alloys) by a process called self-assembly. Hence, this paper reviews the progress of the application of the self-assembly technique for the surface modification of titanium and its alloys.KEY WORDS
ABSTRACT
Introduction: The prevalence of group function and canine guided occlusion is common in natural dentition, but cross arch balance is not often seen. Hence, a study was carried out with following objectives: Analysis of incidence of cross arch balance in different age groups and working side occlusal wear facets in following subjects. Materials and Methods: A total of 200 patients with natural dentition were included in the study. Subjects with cross arch balance were analyzed for working side occlusal wear facets. Data were analyzed statistically by Chi-square test. Results: The incidence of cross arch balance in the study group was 0.7%. On examination, subjects with group function on the working side and cross arch balance on the non-working side had more occlusal wear facets. Conclusion: From the study, it was observed that there was no significant variation in the number and extent of wear facets between the cross arch and without cross arch subjects due the smaller sample size hence it was difficult to conclude the relationship non-working side contact as interference and its influence in wearing of dentition in this study.
