Dental implants act as a bridge between the oral environment and deep core structures of the jaw. The temperature rise leading to heat generation in the course of operation of the dental implants results in thermal injury of the adjoining bone tissue to the implant site resulting into implant failure. Present review is focused on existing research done in the heat generation and its distribution during dental implant drilling. Various factors such as drill speed, drill design, mode of irrigation, depth of drill, drill diameter, drill material that affect osseointegration due to heat generated while drilling, are compared. The motive of this review is to assess the various factors that are responsible for heat generation and their effects on osseointegration during osteotomy. A systematic study reveals that the rise in the temperature at the implant site mainly depends upon the drill speed, drill diameter, depth of drill as well as irrigation used. The purpose of this review is taking these factors into consideration to find out the best possible parameters during implantation to avoid bone necrosis. The temperature during dental implantation ranges from 35 ℃ to 43 ℃ while in some in-vitro studies the temperature increases up to 50 ℃ was observed which is not admissible due to the thermally induced necrosis. © 2022

Heat generation during implant site preparation and its effects on osseointegration: A review

The goal of any manufacturer is customer’s satisfaction this can be achieved by delivering the quality product, right on time at reasonable cost. Any organization whether manufacturing or service will survive and sustain the competency if it is flexible enough to continuously and systematically respond to the customers need and accordingly adds value to the product. Equipment, Material, and labour cost will increase with the inflation rate which are the dominant parameters that affect the price of the product. A simple mathematics, underutilization of equipment, material and labour is direct loss incurred. So, without any doubt the first focus of attention must be towards maximum utilization of this dominant parameters followed by reducing wastages in manufacturing activities. Lean manufacturing are now vital tools in all manufacturing sectors like automotive, electronics, plastic, textile, food, dairy, foundry, stampings, maintenance. The benefit observed after implementation of individual or combined lean manufacturing technique was reduction in cycle time, elimination of non-valued activities, clean, tidy, and hygienic workplace. Besides this there will be a smooth production flow, increase in productivity, reduction in production cost, involvement of employees, documentation of orders, reduction of inventory, breakdown with better intra and inter connectivity to take decisions fast and quick response. The present review focuses on different manufacturing sectors to see the effect of lean manufacturing techniques implemented for improving the process and reducing the wastages.

Lean manufacturing a vital tool to enhance productivity in manufacturing

Dental implant is used as restoration of lost tooth caused due to accidental injuries. When dental implant gets osseointegrated, it behaves in a manner like natural teeth as it is continuously acted upon by static and dynamic loads. The forces get transmitted during osseointegration are directed toward jawbone and they induce excessive stresses which may result in implant fracture and fatigue failure. The way in which stresses get transferred to jawbone via interface determine the survivalrate of implant. Therefore, it is important to study the stress concentration at bone-implant interface. Mechanical parameters like stiffness, porosity, mechanochemical parameters and biomechanical parameters like implant length, diameter, thread shape and geometry affect it. Hence, it is essential to optimize these functional parameters to lower the stress intensity at implant-bone interface and improve implant stability. This review paper concentrates on different approaches used in optimization and design of experiments (DoE) techniques to have minimum stress level at the interface. Optimization techniques referred are topology and shape optimization and in DoE techniques Analysis of Variance method (ANOVA), Taguchi method, Sensitivity analysis method are discussed mainly. DoE based implant thread profile optimization by response surface method is an important understand stress distribution along interface. While Taguchi method along with FE analysis is recommended for design of experiments approach where multi factors need to optimize with factorial design
