The cleanness of teeth and condition of teeth shows the characteristics of human. Although for layman it is just a part of body but in medical science its importance is very high. Starting from a small child to old person it is very essential. Still carelessness, bad habits, genitic problems and age are the most important factor for its decay. But Dental doctors and hospitals helps to recover from various dental related prob- lems. For small children, candy, chocolates, sweets, ice-cream are the most hazardous problems that cre- ates tooth decay. So some times the person has to loose his/her teeth from early age or they have to leave with medicines or precautions. Now a days these problems can easily fixed by Dental implants. Since patient satisfaction levels are directly associated with the levels of expectations predicted by the patient prior to a dental implant procedure, if expectations are not achieved, a negative influence on satisfaction levels ensues. It seems logical that such expectations are anticipated when considering the topic area of patient satisfaction since an intrinsic relationship exists between the psychological factors of self- reported confidence levels both prior to and subsequent to treatment and the psychological success of that treatment. So in this paper an effort is taken to find barriers of dental implants by PROMETHEE method. Ó 2020 Elsevier Ltd. All rights reserved.

Introduction The dentist uses a dental implant of titanium post (like a tooth root) to mount replacement teeth or a bridge into that area, which is surgically positioned into the jawbone beneath the gum line that allows the placement of implant. An implant is very tight like a denture can. Like bridges the Dental implants do not have to be anchored to other teeth, but provides general oral health. As Dental implants combine to jawbone and provide firm hold up to artificial teeth, dentures and bridges mounted to implants won’t slide or move in side mouth during eating and speaking. These implants safe and soundly fitted and helps the dentures and bridges plus individual crowns placed over implants. In this way the teeth feel more natural than conventional bridges or dentures. But , in some cases it is found that some people suffers as ordinary bridges and dentures are usually not comfortable , due to sore spots, poor ridges or gagging. To replace the missing tooth ordinary bridges must be joined to either side of the space of the teeth. New replace- ment tooth/teeth is placed without placing adjacent teeth near to it. But implant placement is successfull in case of presence of healthy gums and adequate bone to support the implant. Implants are permanent solution for teeth replacement but usually more expensive than other methods of tooth replacement. There are two methods of implants Endosteal implants and subperiosteal implants. Although dental implant is a very useful technique still dental implant failure rate is also very high. Dental implant failures can take place for several reasons. It may be short-term failures which can be described as a failure to heal in the bone, a process called ‘‘osseointegration”. The short-term failures can be treated by removing the implant, repairing the surgical site with a bone graft and allowing it to heal before attempting to place another fix- ture. Since bone heals much more slowly than soft tissue, this pro- cess can take several months. Long-term dental implant failure https://doi.org/10.1016/j.matpr.2020.09.708 2214-7853/Ó 2020 Elsevier Ltd.
